BACKGROUND AND PURPOSE: To determine the feasibility, toxicity, and clinical
effectiveness of concurrent weekly cisplatin chemotherapy in conjunction with
definitive radiation in the treatment of localised muscle invasive bladder
cancer. PATIENTS AND METHODS: In January 1997 the Trans Tasman Radiation
Oncology Group embarked on a Phase II study (TROG 97.01) of weekly cisplatin
(35mg/m(2)x7 doses) plus radiation to a dose of 63Gy over 7 weeks. Following an
interim toxicity analysis, the dose intensity of cisplatin was reduced to 6
cycles and the radiation schedule changed to 64Gy over 6.5 weeks leading to the
second study (TROG 99.06). A total of 113 patients were enrolled. RESULTS: Acute
grade 3 urinary toxicity occurred in 23% of the patients. Acute grade 4 pelvic
toxicity was not seen. Thirty-eight patients (33%) experienced grade 3 or 4
cisplatin related toxicities with 15 patients (12%) requiring significant dose
modification. The reduced dose intensity in Study 99.06 improved tolerability.
Incidence of significant late morbidity was low (6%). Seventy-nine patients
(70%) achieved complete remission at the 6 month cystoscopic assessment. Local
invasive recurrence was seen in 11 of the 79 patients (14%). In 18 patients
(16%) isolated superficial TCC/CIS were detected (6 months and beyond).The local
control rate was 45% with a functional bladder being retained in 69 of the 113
patients (61%). RFS and DSS at 5 years were 33% and 50%, respectively.
CONCLUSION: Our two sequential Phase II studies have shown that concurrent
chemoradiation using weekly cisplatin in the management of localised invasive
bladder TCC is feasible and reasonably well tolerated. This approach is
currently being investigated further in a randomised study.

Standardization of pelvic lymphadenectomy performed at radical
cystectomy: can we establish a minimum number of lymph nodes that should be
removed?

Sloan-Kettering Cancer Center, New York, New York.
BACKGROUND.: The number of lymph nodes (LNs) removed during radical cystectomy
(RC) for transitional cell carcinoma (TCC) of the bladder affects overall and
disease-specific survival, but no consensus exists regarding the minimum number
of LNs that should be removed. The goal of the current study was to determine if
a threshold number of nodes exists, above which taking additional LNs has no
clinical benefit. METHODS.: A total of 1121 patients were identified who
underwent RC for clinically localized TCC of the bladder between January 1990
and April 2004. To determine the relation of LNs removal and overall survival, a
Cox proportional hazards model was used with pathologic stage, age, and
comorbidity as covariates. A dose-response curve, adjusted for covariates, was
modeled to assess the impact of an increasing number of LNs removed on overall
survival. RESULTS.: A median of 9 LNs were removed (range, 0-53 LNs). In
multivariable analysis, all covariates (number of LNs removed, age, stage of
disease, and comorbidity) were found to be predictive of survival. The
dose-response curve for number of LNs versus survival revealed that, when
adjusted for covariates, the probability of survival did not plateau but instead
continued to rise as the number of LNs removed increased. CONCLUSIONS.: No
evidence was found that a minimum number of LNs is sufficient for optimizing
bladder cancer outcomes when a limited or extended pelvic LN dissection is
performed during RC. Instead, the probability of survival continues to rise as
the number of LNs removed increases. This study supports a more extended LN
dissection at the time of RC, and highlights the challenges of interpreting
retrospective LN dissection data. Cancer 2006. (c) 2006 American Cancer Society.

State-of-the-art management of metastatic disease at initial
presentation or recurrence.

Carcinoma of the bladder is the second most prevalent genitourinay malignancy
and the fifth most common solid tumor in the USA. On the basis of favorable
response rates and survival data, cisplatin-based regimens can be considered the
standard treatment for fit patients with metastatic urothelial cancer. Since
cisplatin-containing regimens are contraindicated for patients with impaired
renal function, gemcitabine plus either paclitaxel or docetaxel may be an
effective and well-tolerated treatment option for these patients. Randomized
trials are needed to determine the future role of these combinations in the
management of advanced transitional cell carcinoma. The optimal regimens for the
medically unfit patients and second-line chemotherapy remain undefined.
Postchemotherapy surgical resection of residual cancer may result in a
disease-free survival in highly selected patients who would otherwise die of the
disease. Progresses in the understanding of the molecular biology of bladder
cancer and identification of new targeted therapies will undoubtedly provide new
opportunities but whether or not this approach to therapy will lead to better
results must still be determined.

Chemotherapy in Patients with Locally Advanced Bladder Cancer.

Section of Hematology/Oncology, University of Chicago, IL.
Background: Despite the general acceptance of gemcitabine/cisplatin in
metastatic bladder cancer, its role and tolerability in the adjuvant setting, in
which renal insufficiency is common, is unclear. Patients and Methods: A total
of 39 patients with locally advanced transitional cell carcinoma of the bladder
(T2-T4, N0-N2) were treated with 4 cycles of gemcitabine/cisplatin/amifostine
after radical cystectomy. All toxicities were evaluated by the National Cancer
Institute Common Toxicity Criteria. Tumor samples were immunohistochemically
stained for pRB, p53, and p16. Results: Thirty-five patients (90%) completed 4
cycles of chemotherapy. Eleven patients (28%) experienced grade 4 hematologic
toxicity, and 14 patients (36%) experienced grade 3 nonhematologic toxicity. The
median increase in creatinine was 0.3 mg/dL. With a median follow-up of 22.8
months (range, 7-70 months), 13 patients (33%) had recurrent disease, 1 patient
at 6 years after completion of therapy. Twelve patients (31%) died, including 11
(28%) with recurrent disease. Thirty-three tumor blocks were evaluated for pRB,
p53, and p16 alterations. In an exploratory analysis, altered expression of p53,
p16, and pRB was found in 15 (45%), 22 (67%), and 30 patients (91%),
respectively. No association between altered p53 and disease-free or overall
survival was detected, but altered p16 and pRB expression was associated with
better outcome (P </= 0.001). Conclusion: Gemcitabine/cisplatin with amifostine
is tolerated in the adjuvant setting for patients with locally advanced bladder
cancer. The favorable prognostic value of altered p16 and pRB raises the
hypothesis of a relative beneficial effect of chemotherapy in this population
but needs verification in other studies.

Recent improvements in the detection and treatment of nonmuscle-invasive
bladder cancer.

In total, 70-80% of newly diagnosed bladder cancers are confined to the mucosa
and staged as Ta, T1 or carcinoma in situ according to the 2002 tumor, lymph
nodes and metastasis classification. The standard treatment for these nonmuscle-invasive
bladder cancers is transurethral tumor resection with or without adjuvant
intravesical chemotherapy or intravesical immunotherapy and subsequent
follow-up. Diagnosis and follow-up of nonmuscle-invasive bladder cancer offers
two main problems. First, approximately 10-20% of all tumors are not seen in
standard cystoscopy. Additionally, frequently repeated follow-up cystoscopies
are bothersome for the patient. As an adjunct to standard cystoscopy,
fluorescence-guided cystoscopy has demonstrated significantly higher tumor
detection rates and optimized patient treatment in recent Phase III studies.
Second, routinely performed urine cytology is characterized by high specificity
but low sensitivity. Today, several urine tests are available that may increase
diagnostic accuracy and potentially prolong intervals of follow-up cystocopy.
Owing to rather high recurrence rates after transurethral tumor resection in
most tumors and high progression rates in poorly differentiated tumors, adjuvant
intravesical chemotherapy or intravesical immunotherapy has gained widespread
use in patients with nonmuscle-invasive bladder cancer. Only a few further
immunomodulatory drugs, such as recombinant cytokines, have shown significant
clinical effectiveness. Additional approaches, such as photodynamic therapy with
different photosensitizers and thermotherapy in combination with intravesical
chemotherapy, have been evaluated in Phase III studies.

Removal of more lymph nodes may provide better outcome, as well
as more accurate pathologic findings, in patients with bladder cancer--analysis
of role of pelvic lymph node dissection.

OBJECTIVES: To examine the role of pelvic lymph node dissection (PLND) in
patients who underwent radical cystectomy for bladder cancer. The diagnostic and
therapeutic role of PLND is still controversial in bladder cancer. The extent of
PLND and the necessary number of lymph nodes to remove have not been defined.
METHODS: This retrospective review included 146 patients with refractory
superficial and muscle-invasive disease treated with radical cystectomy,
regional PLND (internal iliac, external iliac, and obturator nodes) and urinary
diversion from January 1990 to December 2002. RESULTS: Lymph node metastases
were detected in 25 patients (17.1%). The average number of nodes removed in the
node-positive and node-negative patients was 13.9 and 14.2, respectively.
Although no difference was found in disease-specific survival in the
node-negative patients when stratified by the number of nodes removed (13 or
more versus less than 13), a significant survival advantage was found in the
node-positive patients with 13 or more nodes removed versus less than 13 nodes
removed. The patients with four or more positive nodes had a worse outcome than
those with less than four positive nodes. However, even if the patients had less
than four positive nodes, the survival of patients with less than 13 nodes
removed was as poor as that of the patients with four or more positive nodes.
CONCLUSIONS: In this series, the removal of 13 or more pelvic lymph nodes was
essential for more accurate pathologic examination to predict patient outcome
and contributed to an increased chance of survival.

The prognostic and staging value of lymph node dissection in the
treatment of invasive bladder cancer.
Sanderson KM, Skinner D, Stein JP.
Department of Urology, at the University of Southern California, Keck School of
Medicine, Los Angeles, CA 90089, USA. sanderson.km@gmail.com
Regional lymph node dissection (LND) at the time of radical cystectomy is an
essential component of the surgical management of invasive bladder cancer and
might provide diagnostic and therapeutic benefits for both node-negative and
node-positive patients. The benefits obtained in pathologically node-negative
patients might result from more complete resection of undetected micrometastases
or from a more meticulous surgical technique. Advanced nodal disease also seems
to be amenable to thorough surgical resection in a subpopulation of patients
with bladder cancer. Despite the growing body of evidence to support the role of
a more extended LND, no guidelines regarding the optimal boundaries of LND have
been established. An increased number of resected nodes and wider LND boundaries
have been associated with improved local disease control and prolonged survival.
Additionally, mapping series indicate that the common iliac and presacral nodal
regions are more frequently involved with tumor metastases than previously
recognized. Efforts to limit any unnecessary dissection in patients at low risk
for metastases--a tailored approach--has been proposed, but remains unproven.
From the available evidence, the most reliable diagnostic and therapeutic
approach to LND includes the routine extended LND in all patients undergoing
cystectomy with curative intent.

Randomized prospective phase III trial of difluoromethylornithine
vs placebo in preventing recurrence of completely resected low risk superficial
bladder cancer.

PURPOSE: Ornithine decarboxylase catalyzes the rate limiting step in polyamine
synthesis and its activity can be inhibited by difluoromethylornithine, which
has been shown in preclinical studies, to prevent bladder cancer. MATERIALS AND
METHODS: To assess the ability of difluoromethylornithine to prevent recurrence
of low risk superficial bladder cancer, 454 patients with newly diagnosed (283)
or occasionally recurrent (171), stage Ta (425) or T1 (29), grade 1 (263) or
grade 2 (191), completely resected urothelial cancer were randomized to receive
1 gm difluoromethylornithine daily or placebo for 1 year. Patients were followed
with cystoscopy every 3 months for 2 years and then semiannually for 2 years or
until first recurrence. Index and recurrent tumors underwent central pathology
review. RESULTS: No serious drug related toxicities were seen in either arm. Two
patients died of bladder cancer at 2 and 4 years after randomization, both in
the difluoromethylornithine arm. At 42 months followup, 103 patients in the
difluoromethylornithine arm (46%) and 97 in the placebo arm (43%) (p = 0.30)
experienced at least 1 tumor recurrence. Over 73% of recurrences occurred within
1 year in each arm. Each arm had similar responses for each stratification
factor. During the 42 months of followup, 10 (4.4%) difluoromethylornithine and
9 (3.9%) placebo treated patients had progression to TIS or grade 3 disease, and
2 (0.9%) in the difluoromethylornithine arm and none in the placebo arm
developed stage T2+ cancers. CONCLUSIONS: A year of difluoromethylornithine did
not prevent recurrence of completely resected low risk superficial bladder
cancer, when started shortly after surgery.

Lymphadenectomy in bladder cancer: How high is "high enough"?
Stein JP.
Department of Urology, Norris Comprehensive Cancer Center, University of
Southern California Keck School of Medicine, Los Angeles, CA 90089, USA.
PURPOSE: The role of a regional lymphadenectomy in the surgical treatment of
high-grade, invasive transitional cell carcinoma of the bladder has evolved over
the last several decades. Although the application of a lymphadenectomy for
bladder cancer is not significantly debated, the absolute extent or level of
proximal dissection of the lymphadenectomy remains a controversial issue.
MATERIAL AND METHODS: A review of the literature should help elucidate the
rationale and extent of an appropriate lymphadenectomy in patients undergoing
radical cystectomy for bladder cancer. Various surgical issues of
lymphadenectomy as well as prognostic factors in patients undergoing radical
cystectomy for bladder cancer are examined. RESULTS: A growing body of evidence,
spanning from early autopsy and cadaveric studies to recent retrospective series
and multicenter prospective trials, suggests that an extended lymph node
dissection (cephalad extent to include the common iliac arteries) may provide
not only prognostic information but also provide a therapeutic benefit for both
patients with lymph node-positive and lymph node-negative disease undergoing
radical cystectomy for bladder cancer. Although the absolute boundaries of the
lymphadenectomy remain a subject of controversy, historical reports confirmed by
recent lymphatic mapping studies suggest the inclusion of the common iliac as
well as possibly presacral nodes in the routine lymphadenectomy for transitional
cell carcinoma of the bladder. The need to extend the dissection higher to
include the distal para-aortic and paracaval lymph nodes may be important in
select individuals but remains more controversial. The extent of the primary
bladder tumor (p-stage), number of lymph nodes removed, the lymph node tumor
burden (tumor volume), and lymph node density (number of lymph nodes
involved/number of lymph nodes removed) are all important prognostic variables
in patients undergoing cystectomy with pathologic evidence of lymph node
metastases. Systemic adjuvant chemotherapy remains a mainstay of treatment of
patients with lymph node metastases. CONCLUSIONS: Radical cystectomy with an
appropriately performed lymphadenectomy provides the best survival outcomes and
lowest local recurrence rates. Although the absolute limits of the lymph node
dissection remain to be determined, evidence supports a more extended
lymphadenectomy to include the common iliac vessels and presacral lymph nodes at
cystectomy in patients who are appropriate surgical candidates. When feasible,
adjuvant chemotherapy is warranted in patients with positive nodal metastasis.

(J-107088), a novel topoisomerase I inhibitor, in patients with advanced solid
tumors.

3052, Durham, NC, 27710, USA, hurwi004@mc.duke.edu.
PURPOSE : To assess the maximum tolerated dose, safety, and pharmacokinetic (PK)
profile of escalating doses of the novel topoisomerase I (topo I) inhibitor
edotecarin (J-107088) given as a 2-h intravenous (IV) infusion once every 21
days in patients with advanced solid tumors who had not responded to standard
therapy. PATIENTS AND METHODS : Twenty-nine patients (18M:11F) received a 2-h IV
infusion of edotecarin in doses of 6, 8, 11, 13, or 15 mg/m(2) every 21 days
(with an additional 1-2 weeks permitted for recovery) and were evaluated for
safety, PK, and tumor response. RESULTS : The most common non-hematologic
toxicities were grade 1-2 nausea, fatigue, anorexia, vomiting, and fever. The
most common hematologic toxicities were grade 1-2 thrombocytopenia and grade 3-4
neutropenia, leukopenia, and anemia. No grade 3-4 diarrhea was reported.
Dose-limiting toxicities were observed in four patients at the 15 mg/m(2) dose
and one patient at the 13 mg/m(2) dose. These toxicities included grade 3
nausea, vomiting, headache, and fatigue, as well as grade 4 neutropenia and
febrile neutropenia. The maximum tolerated dose was declared at 15 mg/m(2). One
patient with bladder cancer had a confirmed partial response at a dose of 13
mg/m(2). There was a trend to dose-proportional increases in edotecarin peak
plasma concentrations and area under the curve values. Renal excretion of
edotecarin was minimal (3-8% of the dose). CONCLUSION : The recommended Phase II
dose of edotecarin is 13 mg/m(2) once every 21 days. The toxicities in this
study were those typical of cytotoxic chemotherapy and less severe than those
associated with other topo I inhibitors. The observed safety profile and
preliminary evidence of clinical benefit warrant further investigation of this
drug as monotherapy or part of combination therapy in patients with solid
tumors.

Benson MC.
Columbia University Medical Center, 161 Fort Washington Ave, 11th Floor,
Department of Urology, New York, NY 10032, USA.
PURPOSE: Up to 50% of patients treated with intravesical agents for superficial
bladder cancer will experience recurrence. Response rates to second-line
intravesical therapies range from 20% to 40%. For these high-risk patients,
novel agents are necessary to prevent recurrence. Docetaxel is a microtubule
depolymerization inhibitor with unique physiochemical properties, making it an
excellent candidate for investigation as an intravesical agent. PATIENTS AND
METHODS: This phase I trial included patients with recurrent Ta, T1, and Tis
transitional cell carcinoma who experienced treatment failure with at least one
prior intravesical treatment. Docetaxel was administered as six weekly
instillations at a starting dose of 5 mg, with a dose-escalation model used
until a maximum tolerated dose (MTD) was achieved. Primary end points were
dose-limiting toxicity (DLT) and MTD. Efficacy was evaluated by cystoscopy with
biopsy, cytology, and computed tomography imaging. RESULTS: Eighteen patients
(100%) completed the trial, and the distribution of stages included six patients
with Tis, seven with Ta, and five with T1 disease. No grade 3 or 4 DLTs occurred
in 108 infusions, and no patient had systemic absorption of docetaxel. Eight
(44%) of 18 patients experienced grade 1 or 2 toxicities, with dysuria being the
most common. Ten (56%) of 18 patients had no evidence of disease at their
post-treatment cystoscopy and biopsy. None of the patients who experienced
relapse had disease progression. CONCLUSION: Intravesical docetaxel exhibited
minimal toxicity and no systemic absorption in the first human intravesical
clinical trial. This suggests that docetaxel is a safe agent for further
evaluation of efficacy in a phase II trial.

[Intra-arterial chemotherapy for invasive bladder cancer
(T2-3N0M0)]
[Article in Japanese]

We assessed the effectiveness of intra-arterial MVAC chemotherapy or a
combination of intra-arterial chemotherapy and external beam radiotherapy based
on diagnostic images and histological (transurethral) examination in 15 cases
with T2-3NOM0 between January 2003 and September 2005. When the clinical
response was assessed one month after the treatments, a complete response (CR)
was achieved in 20% (1/5) and 50% (5/10) by intra-arterial MVAC chemotherapy and
a combination of intra-arterial chemotherapy and external beam radiotherapy,
respectively. Total radical cystectomy was required on one patient during the
follow-up period of 4-26 months. Although our result showed that the combination
of external beam radiation therapy and intraarterial cisplatin effectively
contributed to the preservation of the bladder with localized invasive bladder
cancer, radical cystectomy is required when CR is not achieved after this
treatment.

Delay in the Surgical Treatment of Bladder Cancer and Survival:
Systematic Review of the Literature.
Fahmy NM, Mahmud S, Aprikian AG.
Department of Surgery (Urology), McGill University, Montreal, Quebec, Canada.
OBJECTIVES: Eighty per cent of the newly diagnosed invasive bladder tumours are
invasive from the outset. Half of these patients already have occult distant
metastases reflecting the rapid nature of progression. The aim of the current
study was to review the literature to determine if delay in cystectomy leads to
worse prognosis and to determine if a possible cutoff point for delay exists,
after which a worse outcome would be expected. METHODS: We performed a
systematic review of publications indexed in Medline and other scientific
databases by analyzing types and causes of delay in performing radical
cystectomy. Information on the impact of such delays on tumour recurrence and
survival was collected and summarized. Papers that described only delay without
any outcome correlation were excluded from the study. RESULTS: A total of 13
papers published from 1965 to 2006 were included in this study. Three (23%)
papers did not find any correlation between pretreatment delays and survival.
Two (15%) papers reported a trend towards worse survival with delay. Eight (62%)
papers documented significant association between delay and worse prognosis.
Delay influenced survival as an independent variable in two (25%) of these eight
papers. In the remaining six (75%) manuscripts, delay was significantly
associated with a higher pathologic stage. CONCLUSIONS: Although studies on
bladder cancer failed to show a linear relationship between delay and prognosis,
the majority confirmed that delays are associated with worse outcome. Studies
suggested a window of opportunity of less than 12 weeks from diagnosis of
invasive disease to radical cystectomy.

Laparoscopic Cystectomy with Extracorporeal-Assisted Urinary
Diversion: Experience with 34 Patients.
Gerullis H, Kuemmel C, Popken G.
Department of Urology, HELIOS-Hospital, Berlin Buch, Berlin, Germany.
OBJECTIVES: Open radical cystectomy remains the gold standard for nonmetastatic
muscle invasive bladder cancer. Laparoscopic cystectomy has been described as a
feasible procedure and is still being evaluated. We describe our initial
experience with this laparoscopic surgical approach in 34 patients. METHODS:
From February 2002 to October 2004, 18 men and 16 women underwent laparoscopic
cystectomy with extracorporeal-assisted urinary diversion for transitional cell
carcinoma of the bladder (n=27), invasive cervical carcinoma (n=4), and atrophic
bladder (n=3). We report here on specific technical details and present initial
results of our series. RESULTS: The mean operating time was 244min, the mean
blood loss 325ml, and the transfusion rate 5.9%. All procedures were completed
laparascopically without conversion to open techniques. No major complications
occurred during or after the operation. In case of urothelial malignancy (n=27),
the histopathologic analysis of the removed specimen revealed organ-confined
transitional cell carcinoma of the bladder in 66.7% (pT1:14.8%; pT2: 51.9%) and
locally advanced disease in 33.3% (pT3: 25.9%; pT4: 7.4%). In two cases final
histology proved positive surgical margins. Extended lymphadenectomy detected
lymph node metastasis in two patients. CONCLUSIONS: We demonstrate that the
combination of laparoscopic cystectomy and extracorporeal urinary diversion is
possible and remains a safe, feasible, and repeatable surgical technique. To
determine the oncologic outcome long-time follow-up will be necessary.

Cystectomy delay more than 3 months from initial bladder cancer
diagnosis results in decreased disease specific and overall survival.
Lee CT, Madii R, Daignault S, Dunn RL, Zhang Y, Montie JE, Wood DP Jr.
Michigan Urology Center, University of Michigan, Ann Arbor, Michigan.
PURPOSE: Some groups hypothesize that a delay in cystectomy may result in higher
pathological stage and possibly alter survival in patients with bladder cancer.
The timing of this delay has been somewhat arbitrary. We evaluated the timing
from T2 bladder cancer diagnosis to cystectomy, its impact on survival and
potential causes of delay. MATERIALS AND METHODS: A contemporary cohort of 214
consecutive patients presented with clinical T2 bladder cancer and underwent
radical cystectomy as primary therapy. Clinicopathological parameters were
maintained in an institutional database. A review of time to cystectomy,
pathological stage, disease specific survival and OS was performed. Variables
were tested in univariate and multivariate analyses. The log rank test was used
for exploratory analyses to determine meaningful delay cutoff points. RESULTS:
Mean followup and time to cystectomy in the entire cohort was 40 months and 60
days, respectively. A significant disease specific survival and OS advantage was
observed in patients undergoing cystectomy by 93 days or less (3.1 months)
compared to greater than 93 days (p = 0.05 and 0.02, respectively). Pathological
staging was similar between the groups (p = 0.15). A multivariate benefit in OS
was observed in patients treated with timely cystectomy. The most common factor
contributing to cystectomy delay was scheduling delay, as seen in 46% of cases.
CONCLUSIONS: A cystectomy delay of 3.1 months undermines patient survival,
likely through the development of micrometastases, since local stage progression
is not apparent at this point. Most delays are avoidable and should be
minimized. Despite the need for second opinions and the impact of busy surgical
schedules clinicians must strive to schedule patients efficiently and complete
surgical treatment within this time frame.

Radical cystectomy for invasive bladder cancer: long-term results
of a standard procedure.

Southern California, Keck School of Medicine, MS#74, 1441 Eastlake Avenue, Suite
7416, Los Angeles, CA, 90098, USA, stein@usc.edu.
Radical cystectomy with an appropriate lymphadenectomy remains the standard of
therapy for high-grade invasive bladder cancer. This surgical approach provides
the best survival rates with the lowest local recurrence rates and orthotopic
diversion can be performed safely in most patients with an acceptable outcome
and quality of life. Pathologic analysis of the bladder tumor and regional lymph
nodes will help direct the need for adjuvant therapy in high-risk individuals.
Equivalent long-term local control and survival are not seen with other forms of
treatment including radiation therapy, chemotherapy, or a combination of the
two. The rationale and clinical results of large, contemporary cystectomy series
are presented, which provide a benchmark of outcomes with this form of surgical
treatment.

PURPOSE: Operative mortality from radical cystectomy has decreased as a result
of improvements in surgical and anesthetic care. We reviewed the perioperative
deaths from a large group of patients treated with radical cystectomy for
primary bladder cancer. MATERIALS AND METHODS: All perioperative mortalities
from radical cystectomy were identified from a single high volume institution.
The medical records were reviewed to assess the cause of death as well as
possible contributing factors. RESULTS: From August 1971 to December 2001, 1,359
patients with primary bladder cancer were treated with radical cystectomy and
pelvic iliac lymphadenectomy at our institution. Of these patients, 27 (2%) died
within 30 days of surgery or before discharge from hospital. Median patient age
at surgery was 67 years (range 47 to 78) and males accounted for 81% of the
patients. The median time to death was 28 days from cystectomy (range 0 to 80).
Most deaths were cardiovascular related (including acute myocardial infarction,
cerebrovascular accident, arterial thrombosis) or due to septic complications
with resulting multi-organ system failure, followed by pulmonary embolism,
hepatic failure and hemorrhage. Septic related mortality was most often
associated with postoperative urine or bowel leak. While most deaths occurred
before hospital discharge, 2 patients died at home due to a late pulmonary
embolus. No association was seen between pathological stage or type of urinary
diversion and mortality. CONCLUSIONS: Perioperative mortality from radical
cystectomy is low in this group of patients. Most deaths are due to
cardiovascular or septic complications. Careful patient selection and meticulous
surgical technique may help decrease the incidence of perioperative mortality.

Prostate sparing radical cystectomy- not for all, but an option
for some.
Pinthus JH, Nam RK, Klotz LH.
Department of Surgery, Division of Urology, McMaster University, Hamilton,
Ontario, Canada.
OBJECTIVES: Prostate sparing radical cystectomy (PSRC) is a controversial
surgical approach for the treatment of male bladder cancer. The objective of
this review is to address some of the concerns related to the potential
compromise of oncological outcome compared to radical cystoprostatectomy (RCP)-the
gold standard procedure. METHODS: Review of series published in the English
literature. Only studies that address PSRC for transitional cell carcinoma of
the bladder were included. RESULTS: There are only a limited number of studies
addressing this approach. All are retrospective, non-comparative and not uniform
in terms of patient selection and technique. Long-term follow-up is lacking. The
incidence of synchronous and or metachronous prostate cancer and TCC of the
prostatic urethra is lower than that found in RCP due to pre-operative
screening. The local recurrence rate is 5%- comparable with RCP. Stage for
stage, recurrence free and overall survival are compatible. CONCLUSIONS: The
experience with PSRC is too limited to allow firm conclusions as to whether the
outcome with respect to disease free and disease specific survival is comparable
to that achieved by RCP. However, with proper patient screening and selection
the short-term results appear promising.

Perioperative chemotherapy for localized bladder cancer.
Winquist E.
University of Western Ontario and London Health Sciences Centre, London,
Ontario, Canada.
INTRODUCTION: Survival benefits have been recently reported in meta-analyses of
randomized clinical trials (RCTs) studying perioperative chemotherapy for
muscle-invasive urothelial cancer. Controversy and lack of awareness of these
data have diminished their impact on daily practice, and they deserve further
scrutiny. MATERIALS AND METHODS: Recently published meta-analyses of RCTs
studying perioperative chemotherapy for bladder cancer were narratively
reviewed, along with two reports from the most recently reported RCT of
neoadjuvant chemotherapy for bladder cancer. RESULTS: Two recently published
individual patient data meta-analyses report that cisplatin-based combination
neoadjuvant chemotherapy is associated with an absolute survival benefit of 5%
at 5 years, and adjuvant chemotherapy with an absolute survival benefit of 9% at
3 years. However, the value of the adjuvant meta-analysis is limited by the
available data. Positive surgical margins and fewer than 10 lymph nodes removed
are associated with poorer prognosis. Pathological complete response is
associated with better survival. CONCLUSIONS: Patients diagnosed with
muscle-invasive urothelial cancer may benefit from perioperative chemotherapy
and should be routinely referred to a medical oncologist. Surgical factors
potentially have a greater impact on survival than the use of perioperative
chemotherapy. RCTs studying all stages of localized muscle-invasive bladder
cancer are currently enrolling patients in Canada and are a high priority.

Neo-adjuvant chemotherapy for muscle-invasive bladder cancer: a
look ahead.
Sawhney R, Bourgeois D, Chaudhary UB.
Department of Medicine, Division of Hematology/Oncology, South Carolina, USA.
Randomized clinical trials of neo-adjuvant cisplatin-based combination
chemotherapy for locally advanced muscle invasive bladder cancer has shown a
survival benefit over cystectomy alone. Pathologic complete response (pT0) after
neo-adjuvant chemotherapy is emerging as a potentially important surrogate
clinical end point. Future clinical trials incorporating targeted therapies with
novel clinical end points may accelerate development of therapeutic strategies
for locally advanced muscle invasive bladder cancer. Furthermore, evaluation of
molecular markers may further help to stratify patients to a risk adapted
approach.

Radical radiotherapy for bladder cancer: retrospective analysis
of a series of 459 patients treated in an Italian institution.

Spedali Civili, Brescia, Italy.
AIMS: To contribute to the available evidence about the efficacy of exclusive
radiotherapy for bladder cancer through a retrospective analysis of a large
series of patients consecutively treated in a single institution. MATERIALS AND
METHODS: A total of 459 patients with UICC categories T1-T4, N0-Nx and M0
bladder cancer consecutively treated with radiotherapy alone with radical intent
formed the clinical basis for this study. Many of them (and particularly the T1
cases) had poor medical conditions or were unfit for surgery. About half of the
cases (54%) had a T2 tumour, and about 18% had T3-T4 disease. Eighty per cent of
the cases received minimal doses in the target volume in the range 60-70 Gy;
pelvic lymph nodes were treated in 34%. Simple radiotherapy techniques were used
in most cases. Average follow-up for living patients was 4.4 years. Results were
analysed according to number and type of relapses: overall survival,
disease-specific survival, failure-free survival probability, acute and late
toxicity (RTOG scale). RESULTS: Actuarial 5-year overall survival,
disease-specific survival and failure-free survival rates at 5 years for the
entire series were 36%, 56%, 33%, respectively. Age, T category (for all the end
points) and tumour dose (only for failure-free survival) were significantly
related to prognosis at multivariate survival analysis. Late enteric toxicity
(6.1% of the cases) was significantly linked with the treated volumes (univariate
analysis). Urinary late toxicity (23% of cases) was linked with age and T
category (multivariate analysis). In both cases, toxicity was mostly Grade 1 or
2. CONCLUSIONS: The results of radiotherapy in this negatively selected series,
accrued over a long period of time in patients treated with unsophisticated
techniques, are reasonably good; they add to the evidence available to support
the use of modern bladder-sparing programmes, including the association of
chemo- and radiotherapy.

Adjuvant and neoadjuvant chemotherapy for bladder cancer:
management and controversies.
Garcia JA, Dreicer R.
Department of Hematology and Oncology, The Cleveland Clinic Foundation, OH
44195, USA.
Radical cystectomy remains the gold standard treatment for muscle-invasive
bladder cancer. Although surgery achieves excellent local control, within 5
years almost 50% of patients relapse and subsequently progress to develop
systemic disease. Transitional cell carcinoma of the bladder is sensitive to
chemotherapy. Although platinum-based chemotherapy can produce relatively high
overall response rates, the impact on the survival of patients with advanced
disease has, at best, been limited. Randomized trials of cisplatin-based
chemotherapy regimens in the neoadjuvant setting have demonstrated the potential
to improve survival. By comparison, adjuvant studies have been plagued by
suboptimal trial design, limited patient numbers, and lack of standardization of
the chemotherapy regimens used. With the introduction of new cytotoxic drugs and
novel small molecules, there is a need for well-designed studies to address the
optimal utility of perioperative therapy in high-risk patients with bladder
cancer.

Endoscopic therapy of superficial bladder cancer in high-risk
patients: holmium laser versus transurethral resection.
Muraro GB, Grifoni R, Spazzafumo L.
Centre of Statistic Research on Ageing Department, INRCA, Ancona, Italy.
Many lasers are widely used in urological surgery for several applications.
Their use to treat the superficial bladder cancer (SBC) is safe and minimally
invasive. The Holmium:YAG (Ho:YAG) laser represents the pinnacle of laser
technology in Urology. The authors carried out this study on safety, efficacy,
complication rates, postoperative catheterization time, and hospital stay of
high-risk patients who underwent Ho:YAG vs. transurethral resection (TUR). Two
groups of high-risk patients with SBC and comorbidities underwent either Ho:YAG
or TUR. Different clinical aspects of the tumours and recurrences were
considered. No significant difference between the two groups was noted regarding
number, progression of grade and stage and place and time of recurrences. In the
Ho:YAG patients, perioperative complications occurred at a lower percent than in
the TUR group. Also, in 54% of patients, the catheter was removed within 24
hours; 76% had a postoperative hospital stay of 24 to 48 hours. In the TUR
patients: 4% had the catheter removed within 24 hours and 6% left the hospital
within 24 to 48 hours. In SBC treatment, Ho:YAG and TUR were equally as
effective; the Ho:YAG laser was associated with shorter catheterization time and
hospital stay. These Ho:YAG features could be advantageous from a psychological
standpoint, particularly for elderly, high-risk patients and in terms of
cost:benefit ratios.

Is adjuvant chemotherapy for bladder cancer safer in patients
with an ileal conduit than a neobladder?
Manoharan M, Reyes MA, Kava BR, Singal R, Kim SS, Soloway MS.
Department of Urology, University of Miami School of Medicine, Miami, FL, USA.
OBJECTIVE To assess the safety of adjuvant chemotherapy in patients with
neobladder reconstruction in comparison to ileal conduit, as radical cystectomy
and urinary diversion is an effective curative surgical treatment for
muscle-invasive and high-risk superficial bladder cancer, and adjuvant
chemotherapy is usually considered for patients with clinical stage > T2 and
nodal metastasis. PATIENTS AND METHODS We analysed retrospectively patients who
had had a radical cystectomy and urinary diversion between 1992 and 2004.
Patients with high-risk disease who had adjuvant chemotherapy were identified
and stratified based on the type of urinary diversion (ileal conduit or
neobladder). The chemotherapy regimen, complications from the adjuvant
chemotherapy and other relevant data were analysed. RESULTS Overall, 343
patients had radical cystectomy, 40 had adjuvant chemotherapy; 25 had an ileal
conduit and 15 had a neobladder. Patient characteristics including age, stage
and follow-up were similar. In all, 55% of patients had grade 1 toxicity, 23%
grade 2, 18% grade 3, and 13% grade 4. No patients had serious organ toxicity
and none died. There were no significant differences in the toxicity among the
two groups. CONCLUSIONS Adjuvant chemotherapy appears to be safe in patients
with a neobladder and equally safe in patients with an ileal conduit. Hence
neobladder reconstruction should not be denied to patients with bladder cancer
who are at high risk of recurrence and who might require adjuvant chemotherapy.

Restaging transurethral resection of high risk superficial
bladder cancer improves the initial response to bacillus Calmette-Guerin
therapy.
Herr HW.
Department of Urology, Memorial Sloan-Kettering Cancer Center, 1275 York Avenue,
New York, NY 10021, USA. herrh@mskcc.org
PURPOSE: This study was an evaluation of whether restaging transurethral
resection (TUR) of superficial bladder cancer improves the early response to
bacillus Calmette-Guerin (BCG) therapy. MATERIALS AND METHODS: A total of 347
patients with high risk superficial bladder cancer (high grade Ta and T1 tumors
associated with carcinoma in situ) underwent a single transurethral resection (TUR,
132 patients) or restaging TUR (215 patients) before receiving 6 weekly
intravesical BCG treatments. The patients were evaluated for response (presence
or absence of tumor) at first followup cystoscopy, at 6 and 12 months after
treatment, and evaluated for disease stage progression within 3 years of
followup. RESULTS: Of the 132 patients who underwent a single TUR before BCG
therapy, 75 (57%) had residual or recurrent tumor at the first cystoscopy and 45
(34%) later had progression, compared with 62 of 215 patients (29%) who had
residual or recurrent tumors and 16 (7%) who had progression after undergoing
restaging TUR (p = 0.001). CONCLUSIONS: Restaging TUR of high risk superficial
bladder cancer improves the initial response rate to BCG therapy, reduces the
frequency of subsequent tumor recurrence and appears to delay early tumor
progression.

Phase II Study of Gemcitabine and Cisplatin in Patients with
Advanced or Metastatic Bladder Cancer: Long-Term Follow-Up of a 3-Week Regimen.

Background: Bladder cancer is the fifth most common cancer among men and the
seventh among women. At diagnosis, at least 25% of bladder cancer tumors are
locally or systemically advanced. Systemic chemotherapy is the only current
modality for advanced or metastatic transitional cell carcinoma of the bladder.
Recently, a phase III randomized study has demonstrated that the regimen with
gemcitabine (GMC) and cisplatin (CDDP) had a survival advantage similar to the
standard M-VAC (methotrexate, vinblastine, doxorubicin and cisplatin), with a
better safety profile. Aim: It was the aim of this study to evaluate the tumor
response rate, the median time to progression, the median survival and toxicity
in a 21-day schedule with GMC and CDDP in patients with advanced/metastatic
bladder cancer. Patients and Methods: From September 1998 to December 2000, 27
patients with advanced/metastatic transitional cell carcinoma were enrolled. All
patients received 1,200 mg/m(2) GMC administered as a 30-min intravenous
infusion on days 1 and 8, and 75 mg/m(2) CDDP as a 1-hour infusion on day 2.
Cycles were repeated every 21 days. The patients had a median age of 59.8 years
(range 39-75) and an Eastern Cooperative Oncology Group performance status of
0-2. Results: Twenty-five patients were valuable for toxic effects, length of
survival and tumor response. The statistical analysis was performed in May 2004.
Mean and median follow-up were 20.23 and 13.2 months (range 2-68), respectively.
The overall remission rate (complete response + partial response) was 48% (95%
CI 28.4-67.6%). The median time to progression was 9 months (range 2-56). The
median duration of survival for all patients was 13.2 months (range 2-68+), with
1-year and 23-month survival rates of 60 and 20%, respectively. There was no
grade 4 toxicity or treatment-related death. Grade 3 anemia was observed in 4
patients (16%) and grade 3 thrombocytopenia occurred in 6 patients (24%). No
grade 3-4 nausea/vomiting or neutropenia was observed. Conclusion: GMC and CDDP
is an active schedule with a good safety profile in a 21-day regimen. It may be
a valid alternative to the standard 28-day regimen due to its high tumor
response and survival with a low incidence of toxicity, especially in pretreated
and metastatic patients. Copyright (c) 2005 S. Karger AG, Basel.

[Clinical investigation on the effect of intravesical
instillation of antifibrinolytic agents with bacillus Calmette-Guerin on
preventing bladder cancer recurrence.]
[Article in Chinese]
Ding GQ, Shen ZJ, Lu J, Jin XD, Chen J, Shi SF.
Department of Urology, Sir Run Run Shaw Hospital of Medical School, Zhejiang
University, Hangzhou 310016, China.
OBJECTIVE: To investigate the effect of intravesical instillation of
antifibrinolytic agents with bacillus Calmette-Guerin (BCG) on preventing
recurrence of surperficial bladder transitional cell carcinoma (BTCC) after
surgical management. METHODS: A total of 326 cases of superficial BTCC
undergoing transurethral resection of bladder tumor (TURBT) or partial
cystectomy were divided into 5 groups. Then the different dosage BCG with or
without antifibrinolytic agents was regular instilled into bladders (once a
week, then once a month after 6 times). Group A including 66 cases received
intravesical instillation of 100 - 120 mg BCG plus 100 mg para-aminomethyl
benzoic acid (PAMBA). Group B including 64 cases: instillation of 50 - 60 mg BCG
plus 100 mg PAMBA; Group C including 65 cases: 100 - 120 mg BCG plus 2.0 g
epsilon-aminocarproic acid (EACA); Group D including 64 cases: 50 - 60 mg BCG
plus 2.0 g EACA; Group E (control group) including 67 cases: 100 - 120 mg BCG.
All the cases had been followed up for 4 to 69 months (mean, 28.5 months). Not
only was cystoscopy performed every 3 monthes, but also iopsy was carried out to
identify recurrence when necessary. Side effect was recorded after instillation.
RESULTS: The rate of tumor recurrence of Group A, Group B, Group C and Group D
was 12%, 10%, 9%, 9% respectively, which was significantly lower than that of
Group E (30%) (chi(2) = 5.699, 6.818, 7.380, 7.867, P = 0.017, 0.009, 0.007,
0.005). And there was no significant difference of tumor recurrence rate between
Group A and Group B or between Group C and Group D (Group A and Group C: high
dosage BCG plus antifibrinolytic agents, while Group B and Group D: low dosage
BCG plus antifibrinolytic agents) (P > 0.05). But the side effects developing in
Group B and Group D after BCG instillation were less than those in Group A and
Group C. CONCLUSIONS: The efficacy of BCG on prevention the recurrence of
surperficial BTCC can be enhanced when combined with antifibrinolytic agents.
Even if the dosage of BCG was reduced by half, the efficacy didn't changed. A
new approach of low dosage BCG plus antifibrinolytic agents is recommended in
the prophylaxis of recurrence of bladder cancer.

The role of taxanes in the management of bladder cancer.
Galsky MD.
Memorial Sloan-Kettering Cancer Center, 1275 York Avenue, NY, NY 10021, USA.
Galskym@mskcc.org.
Transitional cell carcinoma of the bladder is a chemo-sensitive neoplasm.
Whereas the MVAC (methotrexate, vinblastine, doxorubicin, and cisplatin) regimen
was long considered the standard of care for patients with advanced disease, the
evaluation of newer agents with retained activity and improved tolerability has
been the focus of much investigation over the past decade. Among the most
important of these newer agents are taxanes. Whereas taxane-containing regimens
have not yet been shown to improve the survival of patients with transitional
cell carcinoma in randomized trials, ongoing phase III trials will further
define the role of these agents in both the perioperative and advanced disease
settings.

Systemic chemotherapy in inoperable or metastatic bladder cancer.
Bamias A, Tiliakos I, Karali MD, Dimopoulos MA.
Department of Clinical Therapeutics, Medical School, University of Athens,
Greece.
Urothelial cancer is a common malignancy. The management of patients with
recurrent disease after cystectomy or initially metastatic or unresectable
disease represents a therapeutic challenge. Systemic chemotherapy prolongs
survival but long-term survival remains infrequent. During recent years there
has been improvement due to the use of novel chemotherapeutic agents, mainly
gemcitabine and the taxanes. The long-considered-standard MVAC has been
challenged by combinations showing more favourable toxicity profiles and equal (gemcitabine-cisplatin)
or even improved (dose-dense, G-CSF-supported MVAC) efficacy. Specific interest
has also been generated in specific groups of patients (elderly patients,
patients with renal function impairment or comorbidities), who are not fit for
the standard cisplatin-based chemotherapy but can derive significant benefit
from carboplatin- or taxane-based treatment. Retrospective analyses have enabled
the identification of groups of patients with different prognoses, who possibly
require different therapeutic approaches. Modern chemotherapy offers a chance of
long-term survival in patients without visceral metastases, possibly in
combination with definitive local treatment. Finally, the progress of targeted
therapies in other neoplasms seems to be reflected in advanced bladder cancer by
recent studies indicating that biological agents can be combined with modern
chemotherapy. The true role of such therapies is currently being evaluated.

Bladder cancer: current optimal intravesical treatment.
Lamm DL, McGee WR, Hale K.
BCG Oncology, PC, Phoenix, AZ, USA.
Superficial bladder cancer can be treated surgically, but patients are at high
risk for recurrence. Tumors are categorized as low, intermediate, and high-risk
based on grade, stage, and pattern of recurrence. Low-risk tumors are best
treated with a single instillation of chemotherapy (thiotepa, doxorubicin, or
mitomycin) (Lamm, 2002). Though effective, the toxicity of bacillus Calmette-Guerin
immunotherapy (BCG) restricts its use to treat higher-grade tumors. Intermediate
risk tumors can be treated with chemotherapy as well, but will often require
immunotherapy. High-risk tumors are best treated with intravesical BCG using a
3-week maintenance schedule. Side effects of BCG immunotherapy can be decreased
by logarithmic reductions in dose. Patients who fail BCG may be rescued with BCG
plus interferon alfa or radical cystectomy.

Novel therapies in bladder cancer.
Alonzi R, Hoskin P.
Mount Vernon Hospital, Northwood, Middlesex, UK.
The most effective non-surgical treatment for bladder cancer remains
radiotherapy. The dramatic technical developments in radiotherapy have enabled
greater accuracy and reliability based on three-dimensional imaging for both
planning and verification. Particle therapy, in particular using protons,
provides further opportunities for optimising radiation delivery and dose
escalation. Novel fractionation schedules with both hyperfractionation and
hypofractionation may have added benefits. Chemoradiation has been shown in one
randomised-controlled trial to improve the results of radiotherapy alone, and
requires further investigation. Hypoxia modification using carbogen and
nicotinamide has also shown promising results in a phase II trial, and is now in
phase III evaluation. Novel drug agents for bladder cancer are few, but the
anti-EGFR agents and anti-angiogenic agents may have promise; the development of
anti-apoptotic agents and antisense gene therapy may also become a component of
the future multimodality management of this tumour.

Chemotherapy for metastatic bladder cancer.
Roberts JT.
Northern Centre for Cancer Treatment, Newcastle General Hospital, Newcastle upon
Tyne, UK. trevor.roberts@nuth.nhs.uk
This paper reviews the current status of systemic chemotherapy in the management
of advanced and metastatic urothelial cancer. The activity of a number of single
agents and combination drug regimens is discussed, and the small number of
randomised-controlled studies available is also considered. Prognostic factors
for response and survival, particularly long-term survival after systemic
chemotherapy, are also reviewed. Special consideration is given to the role of
systemic chemotherapy as a precursor to surgery (or radiotherapy) in locally
advanced disease that is initially considered incurable. Therapeutic options for
patients unable to tolerate cisplatin owing to renal impairment or other
comorbidities are explored. Future directions are explored, including the role
of molecular phenotyping in providing prognostic information, indicators of the
likely success of conventional therapeutic measures and the development of
specific targeted therapies.

Neoadjuvant chemotherapy in transitional-cell carcinoma of the bladder (TCC)
improves survival. This is one of the most important developments in the
management of muscle-invasive bladder cancer in recent times. There is an
improved absolute 5-year survival of at least 5% for T2-T4 disease. To achieve
this benefit, a cisplatin-containing combination is required. There is no
difference in survival whether radical radiotherapy or radical cystectomy is
given as subsequent definitive treatment.

OBJECTIVES: To determine the tolerability and efficacy after 1 year of weekly
intravesical gemcitabine therapy in patients with intermediate-risk and
high-risk superficial transitional cell carcinoma. METHODS: A total of 116
patients with intermediate-risk and high-risk bladder cancer who had undergone
transurethral resection were treated with one cycle (once a week for 6 weeks) of
gemcitabine 2000 mg. Local and systemic tolerability and efficacy were
evaluated. RESULTS: In terms of the tolerability of gemcitabine, 14 patients
(12.0%) reported urgency, 6 (5.1%) dizziness and slight fever (less than 38
degrees C), 1 (0.8%) severe abdominal pain, with ulcerative lesions of the
bladder mucosa at cystoscopy, and 1 (0.8%) parosmia. The remaining 94 patients
(81.3%) did not report any local side effects during the treatment period. In
terms of efficacy, recurrence developed in 29 patients (25.4%) a mean of 7
months after transurethral resection; 85 patients (74.6%) were disease free
after 12 months. The univariate analysis showed a greater level of efficacy in
patients with a first occurrence (P = 0.0408), patients who had had no previous
treatment (P = 0.0368), and patients with Stage pTa superficial transitional
cell carcinoma (P = 0.0018). The multivariate analysis did not reveal any
significant data. No significant differences were found between the
intermediate-risk and high-risk patients in tolerability or efficacy. No
recurrence developed in 18 (75%) of 24 intermediate-risk bacille Calmette-Guerin-refractory
or 7 (43.7%) of 16 high-risk bacille Calmette-Guerin-refractory patients.
CONCLUSIONS: The results of our study have confirmed the good tolerability and 1
year efficacy of intravesical gemcitabine. The treatment schedule proposed
resulted in high patient compliance, and the results can be compared with the
results of studies using other intravesical treatments.

Bladder cancer with obstructive uremia: Oncologic outcome after
definitive surgical management.
El-Tabey NA, Osman Y, Mosbah A, Mohsen T, Abol-Enein H.
Urology and Nephrology Center, Mansoura University, Mansoura, Egypt.
OBJECTIVES: To report the surgical and oncologic outcomes of patients with
bladder cancer who present with obstructive uremia. METHODS: A total of 61
patients presented to our institute with obstructive oliguria or anuria
concomitant with bladder cancer. The mean serum creatinine at presentation was
11.4 +/- 5.1 mg%. After stabilization of kidney function following nephrostomy
drainage, only 38 patients were eligible for radical cystectomy. Analysis of the
intraoperative findings, early postoperative course, definitive histopathologic
findings, and long-term functional and oncologic outcome was performed. The mean
follow-up period was 16.2 +/- 8.1 months (range 8 to 134). RESULTS: Radical
cystectomy with bilateral iliac lymphadenectomy was feasible in 26 patients,
palliative cystectomy in 10, and ileal conduit only without cystectomy in 2. The
postoperative morbidity was minimal and treated conservatively. Bladder cancer
causing uremia was invasive in 94.5%, and was pathologic Stage T4 in 30.5% of
cases. At the mean follow-up, treatment failure was observed in 26 patients
(68.4%), with only 12 patients living free of disease and a mean serum
creatinine of 1.4 +/- 0.7 mg%. Although none of the preoperative variables
proved to be predictive of the oncologic outcome, significant correlation was
found between the tumor stage and grade, as well as lymph node involvement, and
treatment failure. CONCLUSIONS: Although bladder cancer causing obstructive
uremia is almost always muscle invasive, with a large proportion of patients
presenting with locally advanced disease, an adequate number of these patients
could achieve long-term disease-free survival.

Prostatic Capsule- and Nerve-sparing Cystectomy in Organ-confined
Bladder Cancer: Preliminary Results.
Martis G, D'Elia G, Diana M, Ombres M, Mastrangeli B.
Department of Urology, S. Camillo Hospital, Viale Kennedy, 02100, Rieti, Italy.
We present a novel radical cystectomy technique that allows bladder cancer
control while maintaining urinary continence and reducing the risk of erectile
dysfunction by sparing the prostatic capsule and the neurovascular bundles.
Between September 1997 and December 2002, 85 men were candidates for cystectomy;
32 were selected for a prostatic capsule- and seminal-sparing cystectomy with
orthotopic urinary diversion. All patients had clinical organ-confined bladder
cancer (cT1 to cT3a). One patient died of unrelated causes. Of the remaining 31
patients, two with pT4, N+ disease underwent three cycles of adjuvant
chemotherapy and are free of disease at 10 and 12 months postoperatively.
Twenty-nine patients with organ-confined bladder cancer are free of disease
after a mean follow-up of 32 months. At 24 months, 98% of the patients are
completely continent during the day and 83% during the nighttime hours. In
addition, 80% of the patients are able to complete sexual intercourse without
auxiliary measures at a mean of 24 months postoperatively. Prostatic capsule-
and nerve-sparing cystectomy permits en bloc removal of the bladder, of the
adenomatous prostatic tissue, and of the seminal vesicles, thereby achieving
local cancer control and preserving erectile function and urinary continence.

Quality of care: partial cystectomy for bladder cancer--a case of
inappropriate use?
Hollenbeck BK, Taub DA, Dunn RL, Wei JT.
Department of Urology, University of Michigan, Ann Arbor, USA. bhollen@umich.edu
PURPOSE: Partial cystectomy is perceived to be a less morbid, less technically
demanding procedure than radical cystectomy, although only select patients
(approximately 6% to 10%) are appropriate candidates (solitary tumor in
space/time, absence of carcinoma in situ). From a quality of care perspective,
overuse of partial cystectomy may signify inappropriate delivery of health care.
MATERIALS AND METHODS: Subjects who underwent extirpative treatment for bladder
cancer between 1988 and 2000 were identified within the Surveillance,
Epidemiology and End Results (SEER, 3,381) registry and the Nationwide Inpatient
Sample (NIS, 22,088). Adjusted models were developed to identify clinical
factors independently associated with the use of partial cystectomy for bladder
cancer treatment within each sample. RESULTS: Among patients who underwent
extirpative surgery for bladder cancer, 18% and 20% of those in SEER and NIS,
respectively, underwent partial cystectomy. Significant decreases in use between
early and later years were noted in both samples (SEER-22% to 13%, NIS-24% to
17%, both p <0.0001). Partial cystectomy was preferentially used in the elderly,
those with stage I disease, females and black patients. Furthermore, partial
cystectomy was more commonly provided in rural, nonteaching, low volume
hospitals. CONCLUSIONS: Trends in national use of partial cystectomy are
consistent between the NIS and SEER with 13% to 17% of patients currently being
treated with partial in lieu of radical cystectomy. Partial cystectomy is
disproportionately used in certain medical centers (nonteaching, rural, low
volume) and patient populations (elderly, black, females, stage I disease)
reflecting selective referral or overuse.

Current status of establishing standards for lymphadenectomy in
the treatment of bladder cancer.
Huang WC, Bochner BH.
Department of Urology, Memorial Sloan-Kettering Cancer Center, New York, USA.
PURPOSE: Pelvic lymph node dissection at the time of radical cystectomy is a
crucial component of the surgical management of invasive bladder cancer. No
established therapeutic or diagnostic guidelines regarding pelvic lymph node
dissection are, however, currently available. We reviewed the past and
contemporary literature to clarify the current role of pelvic lymph node
dissection both as a staging modality as well as potential therapeutic
intervention. RECENT FINDINGS: The role of pelvic lymph node dissection has
evolved over the past 60 years. Although the added benefits of radical
cystectomy over simple cystectomy alone are accepted, an optimal template for
pelvic lymph node dissection has not been established. Increasing evidence
suggesting therapeutic and diagnostic benefits by extending the boundaries of
lymphadenectomy or by increasing the number of nodes excised has been reported.
Much of the recent literature, however, is based on retrospective studies, and
is influenced by factors such as node count variability, inconsistencies in the
quality of the surgery, and the biases in patient selection. Currently, the
optimal boundaries of pelvic lymph node dissection and the minimum number of
nodes to be pathologically examined remain undetermined. SUMMARY: The diagnostic
and therapeutic benefits obtained by extending the limits of lymphadenectomy are
compelling but inconclusive. Establishing standards for pelvic lymph node
dissection will not only increase the consistency of staging and improve the
design and interpretation of clinical trials in invasive bladder cancer but also
help to identify and optimize the therapeutic benefits of lymphadenectomy.
Prospective, randomized trials will be needed to properly establish the extent
of lymphadenectomy required to obtain such benefits.

[Intravesical adjuvant chemotherapy for superficial bladder
cancer - results of a survey in saxony.]
[Article in German]
Steinbach F, Schuster F.
Urologische Klinik, Stadtisches Klinikum Dresden-Friedrichstadt. Steinbach-Fr@khdf.de.
For patients with superficial bladder cancer, adjuvant intravesical chemotherapy
or immunotherapy with Bacillus Calmette-Guerin (BCG) is recommended in national
and international guidelines. We analyzed whether the recommended therapeutic
regimens are used in daily urological practice. Questionnaires concerning the
adjuvant intravesical therapy were sent to 152 urologists in the German Federal
State of Saxony. Of the surveyed physicians, 134 practiced in an outpatient
medical facility and 18 in a hospital. Of the questionnaires, 73 (48.02 %) were
returned and evaluated. An adjuvant intravesical therapy after transurethral
bladder tumor resection was performed in every second patient (median value
50.07 %). The majority of the urologists (79.4 %) treated the bladder tumors
with intravesical chemotherapy or BCG depending on tumor stage and grade of
malignancy. Chemotherapeutic agents or BCG was exclusively used in 13.6 % and
4.1 % of treated patients, respectively. Chemotherapeutic agents were
predominantly applied up to the primary tumor stage T1 and malignancy grade G2.
In cases with recurrent T1 bladder tumors of G2 or higher grade of malignancy,
BCG was the main agent for intravesical treatment. In patients with recurrent
T1G3 tumors, the majority of urologist (57.1 %) preferred another therapeutic
regimen than intravesical instillation. Only 23.2 % of the urologists believed
that intravesical BCG is superior to chemotherapeutic agents. These data
demonstrate that adjuvant intravesical instillation with chemotherapeutic agents
and BCG is well established in urological practice. In contrast to the
recommendations of national and international guidelines, chemotherapeutic
agents are more frequently used in cases with a high risk of progression.

[A randomized study of prophylactic intravesical instillation of
pirarubicin (THP) prior to transurethral resection of
superficial bladder cancer]
[Article in Japanese]

A prospective randomized study was conducted to evaluate the efficacy of
prophylactic intravesical instillation of pirarubicin (THP) prior to
transurethral resection (TUR) of superficial bladder cancer. A total of 63
patients were randomized into two groups, the THP group and the control group.
In the THP group, 30 mg of THP dissolved in 50 ml saline was administered 4
times intravesically for 4 consecutive days before TUR. In the control group, no
instillation was performed before TUR. The patients were followed by cystoscopy
and urinary cytology every 3 months. The non-recurrence rates in the THP group
and control group were 54.1% versus 37.6% at 1 year and 40.4% versus 26.8% at 2
years, respectively (P = 0.086). Time to recurrence for tumors larger than 1 cm
was significantly longer in the THP group (P = 0.0137). Time to recurrence for
single and grade 1+2 tumors tended to be longer in the THP group (P = 0.09, P =
0.079). No significant adverse effects were observed in any patient. Our
findings suggest that intravesical THP instillation prior to TUR would be
effective for patients with single, low grade lesions larger than 1 cm of
superficial bladder cancer.

PURPOSE: To compare long-term survival in patients with locally advanced or
metastatic transitional cell carcinoma (TCC) of the urothelium treated with
gemcitabine/cisplatin (GC) or methotrexate/vinblastine/doxorubicin/cisplatin (MVAC).
PATIENTS AND METHODS: Efficacy data from a large randomized phase III study of
GC versus MVAC were updated. Time-to-event analyses were performed on the
observed distributions of overall and progression-free survival. RESULTS: A
total of 405 patients were randomly assigned: 203 to the GC arm and 202 to the
MVAC arm. At the time of analysis, 347 patients had died (GC arm, 176 patients;
MVAC arm, 171 patients). Overall survival was similar in both arms (hazard ratio
[HR], 1.09; 95% CI, 0.88 to 1.34; P = .66) with a median survival of 14.0 months
for GC and 15.2 months for MVAC. The 5-year overall survival rates were 13.0%
and 15.3%, respectively (P = .53). The median progression-free survival was 7.7
months for GC and 8.3 months for MVAC, with an HR of 1.09. The 5-year
progression-free survival rates were 9.8% and 11.3%, respectively (P = .63).
Significant prognostic factors favoring overall survival included performance
score (> 70), TNM staging (M0 v M1), low/normal alkaline phosphatase level,
number of disease sites (<or= three), and the absence of visceral metastases. By
adjusting for these prognostic factors, the HR was 0.99 for overall survival and
1.01 for progression-free survival. The 5-year overall survival rates for
patients with and without visceral metastases were 6.8% and 20.9%, respectively.
CONCLUSION: Long-term overall and progression-free survival after treatment with
GC or MVAC are similar. These results strengthen the role of GC as a standard of
care in patients with locally advanced or metastatic TCC.

Extent of lymphadenectomy in radical cystectomy for bladder
cancer.

hammad.ather@aku.edu
BACKGROUND: The benefit of pelvic lymphadenectomy in patients with cancer of the
urinary bladder remains controversial. Though the inclusion of lymph node
dissection in conjunction with radical cystectomy for patients with clinically
negative nodes is well accepted, however, the extent of the nodal dissection
remains contentious, particularly in patients with gross disease and T1G3
cancer. The extent of the primary bladder tumor, number of lymph nodes removed
and the lymph node tumor burden are important prognostic variables in patients
undergoing cystectomy. We analyzed the impact of the extent of lymphadenectomy
during radical cystectomy on survival in the contemporary literature. METHODS: A
Pubmed search was carried out for the literature published over the last 15
years using bladder cancer, radical cystectomy, survival, lymphadenectomy and
complications as the key words. We have discussed the extent of lymphadenectomy
on survival and its anatomical basis to determine the optimal number of lymph
nodes to be removed and the concept of node density. RESULTS: Evidence from
contemporary literature indicate significantly increased survival rates after
cystectomy in patients with bladder cancer diagnosed with stages III or IV
disease who have had relatively more lymph nodes examined, suggesting that even
some patients with higher stage disease may benefit from extended pelvic
lymphadenectomy at the time of cystectomy. Studies also indicate that more
extensive lymphadenectomy significantly improved the prognosis of patients with
bladder cancer, not only by providing prognostic information but perhaps it is
also due to its inherent therapeutic value. CONCLUSION: Extended lymph node
dissection improves local control and survival. However, in the absence of
controlled randomized trial this remains a dubitable issue.

Radical cystectomy in patients aged >/= 75 years: an updated
review of patients treated with curative and palliative intent.
Zebic N, Weinknecht S, Kroepfl D.
Department of Urology Kliniken Essen-Mitte, Essen, Germany.
OBJECTIVE To evaluate the morbidity and mortality of radical cystectomy in a
group of unselected patients aged >/= 75 years who were treated with curative
and palliative intent. PATIENTS AND METHODS We retrospectively analysed 53
patients aged 75-90 years (median 78.8 years) who had radical cystectomies
between May 1994 and July 2002. The patients were divided into two groups: 46
were treated with curative intent (group A) and seven with palliative intent
(group B). The indications for cystectomy in group A were recurrent and
otherwise therapy-resistant bladder cancer, severe irritative voiding symptoms,
and recurrent macrohaematuria. The indications in group B were advanced pelvic
malignancy with severe irritative voiding symptoms, severe pain, and recurrent
macrohaematuria requiring blood transfusions. Patients were categorized
according to the American Society of Anesthesiologists classification, with a
score of II in 28 patients, III in 21 and IV in four. Complications and
mortality before, during and after surgery, and the duration of hospital stay
and clinical outcome, were assessed. RESULTS The early mortality rate in group A
was 4% (2/46); in group B two patients died after prolonged complications. The
median (range) hospital stay was 28 (6-56) days, and was significantly longer in
patients with complications, at a median (range) of 36 (6-70) days. The
complication rates early and late after surgery in group A were 22% and 11%,
respectively, and in group B, five of seven (early). The total median survival
was 2 (0.33-7) years. CONCLUSIONS Elderly people undergoing radical cystectomy
have a greater risk of perioperative morbidity and mortality, especially those
with very advanced pelvic malignancies who have had cystectomy with palliative
intent. The incidence of early and late complications in patients treated with
curative intent is acceptable, but the hospital stay is prolonged.

A phase-1 study of sequential mitomycin C and 5-aminolaevulinic
acid-mediated photodynamic therapy in recurrent superficial bladder carcinoma.

Department of Urology, University Hospital of Wales, Cardiff, Wales, UK.
OBJECTIVE To report a phase-1 study of patients with recurrent superficial
bladder cancer treated with photodynamic therapy (PDT) using sequential
mitomycin C and 5-aminolaevulinic acid (ALA). PATIENTS AND METHODS Twenty-four
patients were treated, the primary endpoint being the safety and tolerability of
combined therapy at increasing doses of ALA and light. RESULTS Mitomycin C
instillation was followed by ALA concentrations of 6%, 8% or 10%; there was no
effect on toxicity. The light dose, at a wavelength of 635 nm, was increased
from zero to 25 J/cm(2), with the upper fluences producing transient symptoms.
There were no episodes of skin photosensitivity or systemic toxicity. A total
fluence of 25 J/cm(2) represented the upper light dose for the tolerability of
this procedure by patients. There were no persistently high urinary symptom
scores or reduction in functional bladder capacity up to >/=24 months of
follow-up. In this group, cumulative tumour recurrences were none at 4, two at
8, six at 12, nine at 18 and 11 at 24 months after PDT, respectively. CONCLUSION
Sequential mitomycin C and ALA-PDT is a safe and well tolerated treatment, with
potential for managing difficult-to-control superficial transitional cell
carcinoma and carcinoma in situ of the bladder.

[Lymphadenectomy for bladder cancer Diagnostic and prognostic significance as
well as therapeutic benefit.]
[Article in German]
Leissner J.
Klinik und Poliklinik fur Urologie, Universitatsklinikum, Bonn.
BACKGROUND: Pelvic lymphadenectomy for invasive bladder cancer is not a
standardized procedure and its relevance for staging and prognoses is still
under discussion. A number of retrospective studies have demonstrated a positive
correlation between extent of lymphadenectomy and prognosis after radical
cystectomy.MATERIALS AND METHODS: In a retrospective study, we correlated the
extent of lymphadenectomy with survival after radical cystectomy. Thereafter, we
conducted a prospective study to investigate the limits of pelvic
lymphadenectomy and the pattern of lymphatic spread.RESULTS: Retrospectively, we
found a significantly better survival for patients when 15 and more lymph nodes
were removed. The individual surgeon was also evaluated as an important
prognostic factor.CONCLUSIONS: Based on retrospective data, an extended and
complete pelvic lymphadenectomy improves the prognosis. The cranial border
should be at least at the level of the aortic bifurcation. A prospective
randomized study will have to clarify the effect of lymphadenectomy on the
prognosis of patients after radical cystectomy.

Adjuvant chemotherapy for transitional cell carcinoma of the
bladder: paradigms for the design of clinical trials.

Room 919, 161 Fort Washington Avenue, New York, NY 10032, USA. dpp5@columbia.edu.
Optimal treatment of high-risk, muscle-invasive bladder cancer involves local
and systemic therapy. Published trials of adjuvant chemotherapy in bladder
cancer are limited, but the evidence suggests that the combination of
chemotherapy and surgery in high-risk patients improves survival. The
identification of biologic markers with prognostic significance will allow
clinicians to better determine which patients are at high risk for relapse. The
development of newer, less toxic drugs with activity in bladder cancer has set
the stage for the next generation of trials. Several multicenter randomized
controlled trials are evaluating new chemotherapy regimens in the adjuvant
setting. These new trials represent an important step forward in improving the
treatment of bladder cancer.

The management of lymph node metastasis from bladder cancer.
Simms MS, Mann G, Kockelbergh RC, Mellon JK.
Department of Urology, Leicester Hospital, Gwendolen Road, Leicester LE5 4PW,
UK.
AIM: The presence of pelvic lymph node metastasis from bladder cancer has
traditionally been associated with a very poor prognosis. The aim of this paper
is to review the literature with regard to the management of patients with nodal
disease, particularly gross nodal metastasis and suggest a strategy for
management of these patients. METHODS: We performed a literature search in the
PubMed database and the reference lists of relevant papers describing the
management of locally advanced bladder cancer. FINDINGS: There are no randomised
studies relating specifically to the management of nodal metastasis in bladder
cancer. It is clear however that a significant number of patients with
micrometastatic nodal disease may be cured. Few studies exist which address the
management of patients with gross nodal disease and consist of series from a
limited number of institutions. In patients with gross nodal disease detected
pre-operatively or at the time of surgery, a multimodality approach consisting
of surgery, chemotherapy and possibly radiotherapy seems appropriate. The
prognosis of such patients relates to the pathological stage of the primary
tumour and the degree of lymph node involvement. In addition a good response to
neoadjuvant chemotherapy may identify patients who are likely to survive longer.
CONCLUSIONS: The prognosis for patients with gross nodal disease from bladder
cancer is poor although cure may be possible in a small number of patients. In
such cases a multimodality approach is appropriate and management decisions
should be made on an individual patient basis.

Bladder cancer.
Borden LS Jr, Clark PE, Hall MC.
Department of Urology, Wake Forest University School of Medicine, Winston-Salem,
North Carolina, USA.
PURPOSE OF REVIEW: This article reviews the recent literature concerning
important issues in the management of patients with bladder cancer. A brief
overview of all aspects of bladder cancer including the etiology, diagnosis, and
treatment are discussed with a focus on recent advances. RECENT FINDINGS:
Bladder cancer is a significant cause of morbidity and mortality. The treatment
for bladder cancer should be based on individual patient risk assessment and
should include a multidisciplinary approach. In patients with superficial
bladder cancer, research has focused on improving and optimizing intravesical
therapy to reduce tumor recurrence and progression as well as on methods to
better select the most appropriate treatment for patients with high-risk
features. The important prognostic and therapeutic role of lymphadenectomy
during radical cystectomy has become apparent and recent work has attempted to
better define what should be considered the standard for lymph node dissection.
Finally, in an attempt to improve survival, advances have been made using
systemic chemotherapy in both the perioperative settings as well as for
treatment of metastatic bladder cancer. SUMMARY: Research continues to improve
our understanding of bladder cancer. This ongoing investigation is currently
being translated to the bedside with refinements in the diagnosis and treatment
of patients with bladder cancer.

A randomised trial of accelerated radiotherapy for localised
invasive bladder cancer.
Horwich A, Dearnaley D, Huddart R, Graham J, Bessell E, Mason M, Bliss J.
Academic Unit of Radiotherapy and Oncology, The Royal Marsden NHS Trust and The
Institute of Cancer Research, Sutton, UK.
BACKGROUND AND PURPOSE: To evaluate the efficacy and toxicity of an accelerated
fractionation regimen to treat localised muscle invasive bladder cancer.
PATIENTS AND METHODS: A prospective randomised trial was undertaken in 229
patients randomised between 1988 and 1998 comparing accelerated fractionation
(AF) to a dose of 60.8Gy in 32 fractions over 26 days with conventional
fractionation (CF) treating to 64Gy in 32 fractions over 45 days. Accelerated
fractionation was delivered using two fractions per day with a 6h gap between
fractions and with the first daily fraction size being 1.8Gy and the second
daily fraction size being 2.0Gy. There was a 1 week treatment gap after the
first 12 fractions. Conventional fractionation was one fraction per day, 5 days
per week. Eligible patients had clinical stage T2 or T3, N0 or N1, M0
transitional cell carcinoma. The primary endpoint of the trial was local control
and the trial was powered to detect a 20% difference (alpha 0.05, power 90%).
Secondary endpoints were toxicity and survival. RESULTS: In the initial phase of
the trial, randomisation was unequal such that in total 129 patients were
randomised to accelerated fractionation and 100 to conventional fractionation.
Acute toxicity was evaluable in 121 patients treated with AF and 96 patients
treated with CF. RTOG grade 2 or 3 bowel toxicity was noted in 44% of AF
patients compared to 26% of CF patients (P trend =0.001). Acute grade 2 or 3
bladder toxicity was seen in 35% of AF patients compared to 36% of CF patients
(P=0.99). Late radiation toxicity was evaluated in patients surviving free from
local recurrence at 2 years post treatment. Late radiation toxicity equivalent
to RTOG grade 2 or more had occurred in 44% (95% CI 34-55%) of AF patients and
in 38% (95% CI 26-49%) of CF patients (logrank over 5 years follow-up P=0.23).
There was no significant difference in analysis of time to loss of local tumour
control comparing the two treatment arms; local recurrence was recorded in 29 of
the 100 patients treated with CF and in 41 of 129 patients treated with AF (logrank
P=0.86). There was also no significant difference between the treatment arms
comparing disease-free survival and overall survival. The overall survival
figures at 3 years were for AF 54% (95% CI 45-63%) and for CF 47% (95% CI
36-57%). By 5 years the overall survival was 37% for AF and 40% for CF. There
were two treatment related deaths, both on the AF arm of the trial. CONCLUSIONS:
This accelerated fractionation schedule did not improve on the efficacy of
conventional fractionation for patients with T2 and T3 bladder cancer and
accelerated fractionation was associated with increased acute bowel reactions.

Neoadjuvant chemotherapy for invasive bladder cancer.
Advanced Bladder Cancer Overview Collaboration.
BACKGROUND: Controversy exists as to whether neoadjuvant chemotherapy improves
survival in patients with invasive bladder cancer, despite randomised controlled
trials (RCTs) involving over 3000 patients. OBJECTIVES: To conduct a systematic
review and meta-analysis of individual patient data to evaluate the effect of
neoadjuvant chemotherapy on survival in patients with this invasive bladder
cancer. SEARCH STRATEGY: MEDLINE and Cancerlit searches were supplemented with
information from registers and by hand searching meeting proceedings and also by
discussion with relevant trialists and organisations. These have been regularly
updated until June 2003. SELECTION CRITERIA: Trials that aimed to randomise
patients with biopsy proven invasive (i.e. clinical stage T2-T4a) transitional
cell carcinoma of the bladder to receive local definitive treatment with or
without neoadjuvant chemotherapy were eligible for inclusion. DATA COLLECTION
AND ANALYSIS: We collected, validated and re-analysed updated data on all
randomised patients from all available randomised trials, including 3005
patients from 11 RCTs. For all outcomes, we obtained overall pooled hazard
ratios using the fixed effects model. To explore the potential impact of trial
design we pre-planned analyses that grouped trials by important aspects of their
design that might influence the treatment effect. To investigate any differences
in effect by pre-defined patient subgroups we used a stratified logrank analysis
on the primary endpoint of survival. MAIN RESULTS: These results include data
from one extra trial and so update those in the original publication ABC 2003.
Platinum based combination chemotherapy showed a significant benefit on overall
survival with a combined hazard ratio (HR) 0.86 (95% CI 0.77 to 0.95, p=0.003);
14% reduction in the risk of death; 5% absolute benefit at 5 years (95% CI 1 to
7%); overall survival increased from 45% to 50%. This effect was observed
irrespective of the type of local treatment and did not vary between subgroups
of patients. The HR for all trials, including those that used single-agent
cisplatin, tended to favour neoadjuvant chemotherapy (HR= 0.89, 95% CI 0.81 to
0.98, p=0.022). Although platinum based combination chemotherapy was beneficial,
there was no clear evidence to support the use of single-agent platinum, indeed
there was significant difference in the effect between these groups of trials
(p=0.029). AUTHORS' CONCLUSIONS: This improvement in survival encourages the use
of platinum based combination chemotherapy for patients with invasive bladder
cancer.

Guangdong, 510060, P. R. China. zhoufaj86@263.net.
BACKGROUND & OBJECTIVE: Although total cystectomy plus neobladder is widely
used, with good outcome, to treat men patients with invasive bladder cancer, the
experience of treating women patients with the same therapy is limit. This study
was designed to investigate the outcome of total cystectomy plus sigmoid
neobladder for women patients with invasive bladder cancer. METHODS: Clinical
data of 8 women with invasive bladder cancer, who underwent total cystectomy
plus sigmoid neobladder from Jan. 2002 to Oct. 2003 in Cancer Center of Sun
Yat-sen University, were retrospectively analyzed. RESULTS: The operations were
technically successful in all cases. The mean follow-up was 18 months (ranged
6-24 months). Six patients survived disease-freely;2 developed pelvic metastasis
6 and 12 months after operation respectively. All patients could actively
urinate, 4 were continent day and night, 4 were continent at daytime with mild
nocturnal incontinence. Mild hydronephrosis was detected in 1 patient 3 months
after operation, which disappeared spontaneously 3 months later. Renal function
and serum electrolytes were normal in all cases. CONCLUSIONS: Total cystectomy
plus sigmoid neobladder could manage invasive bladder cancer in women patients,
and the new bladders function well. But night continence in women patients is
not as good as that in men patients.

11st Department of Medical Oncology, St Savas Anticancer Hospital, 171,
Alexandras Avenue, 11522 Athens, Greece.
The purpose of the study was to investigate the toxicity and efficacy of the
combination of gemcitabine and docetaxel in untreated advanced urothelial
carcinoma. Patients with previously untreated, locally advanced/recurrent or
metastatic urothelial carcinoma stage-IV disease were eligible. Patients with
Performance status: PS ECOG >3 or age >75 years or creatinine clearance <50 ml
min(-1) were excluded. Study treatment consisted of docetaxel 75 mg m(-2) (day
8) and gemcitabine 1000 mg m(-2) (days 1+8), every 21 days for a total of six to
nine cycles. A total of 31 patients with urothelial bladder cancer, 25 men and
six women, aged 42-74 (median 64) years were enrolled. The majority of patients
had a good PS (51.6%; PS 0). In all, 15 (48.3%) patients had locally advanced or
recurrent disease only and 16 (54.8%) presented with distant metastatic spread,
with multiple site involvement in 22.5%. Toxicity was primarily haematologic,
and the most frequent grade 3-4 toxicities were anaemia 11 (6.7%)
thrombocytopenia eight (4.9%), and neutropenia 45 (27.6%), with 10 (6.1%)
episodes of febrile neutropenia. No toxic deaths occurred. A number of patients
had some cardiovascular morbidity (38.7%). Nonhaematological toxicities except
alopecia (29 patients) were mild. Overall response rate was 51.6%, including
four complete responses (12.9%) and 12 partial responses (38.7%), while a
further five patients had disease stabilisation (s.d. 16.1%). The median time to
progression was 8 months (95% CI 5.1-9.2 months) and the median overall survival
was 15 months (95% CI 11.2-18.5 months), with 1-year survival rate of 60%. In
conclusion, this schedule of gemcitabine and docetaxel is very active and well
tolerated as a first-line treatment for advanced/relapsing or metastatic
urothelial carcinoma. Although its relative efficacy and tolerance as compared
to classic MVAC should be assessed in a phase III setting, the favourable
toxicity profile of this regimen may offer an interesting alternative,
particularly in patients with compromised renal function or cardiovascular
disease.British Journal of Cancer advance online publication, 1 February 2005;

RA.
Department of Urology.
PURPOSE: A prospective phase I trial was conducted to determine the maximal
tolerated dose of gemcitabine given once weekly during hypofractionated
conformal radiotherapy to patients with locally advanced transitional cell
carcinoma of the bladder. Eight male patients, median age 69 years, with Stage
T2 (n = 4) or T3 (n = 4) N0M0, were enrolled in cohorts of 3. Treatment
comprised conformal radiotherapy (52.5 Gy in 20 fractions) within 4 weeks, with
concurrent gemcitabine once weekly for four cycles. The weekly gemcitabine dose
was escalated from 100 mg/m(2) in increments of 50 mg/m(2) per cohort.
Dose-limiting toxicity was defined as any acute Radiation Therapy Oncology Group
(RTOG) toxicity Grade 3 or greater arising in >1 of 3 patients in each cohort.
Tumor response was assessed cystoscopically and radiologically at 3 months.
RESULTS: All 8 patients completed radiotherapy, and 6 of 8 completed
chemoradiotherapy. No acute toxicity greater than RTOG Grade 1 was seen with
gemcitabine at 100 mg/m(2). Dose-limiting toxicity was observed at 150 mg/m(2)
with Grade 3 toxicity seen in 2 of 2 patients (one bladder, one bowel). An
additional 3 patients received 100 mg/m(2) with minimal toxicity. No hematologic
toxicity was encountered. A complete response was seen in 7 (87.5%) of 8
patients, all of whom were disease free at a median follow-up of 19.5 months
(range, 14-23 months). No late toxicity (greater than RTOG Grade 0) has been
observed. CONCLUSION: The maximal tolerated dose for gemcitabine given once
weekly with concurrent hypofractionated conformal bladder radiotherapy was 150
mg/m(2), with a maximal recommended dose of 100 mg/m(2). This dose regimen has
now entered Phase II clinical trials.

The surgical management of muscle invasive bladder cancer: A
contemporary review.
Cookson MS.
Muscle-invasive bladder cancer is a potentially lethal disease with a high rate
of cure if timely and effective therapy is applied while the disease is confined
to the bladder or regional lymph nodes. Radical cystectomy is the gold standard
to which all other local therapies including multimodality bladder-preserving
strategies should be compared. Contemporary cystectomy combined with regional
lymphadectomy may be performed with an acceptably low morbidity, provides
unparalleled local control, and may result in durable disease-free survival even
among patients with locoregional lymph node metastases. Refinements in surgical
technique coupled with the expanded application of continent urinary diversion
have resulted in excellent functional outcomes without compromising cancer
control in properly selected patients. An increasing awareness of the importance
of quality-of-life issues combined with an enhanced understanding of tumor
biology have resulted in the surgical modifications which include an expanded
role for lymphadectomy and preservation of uninvolved adjacent organs.

Organ preservation by combined modality treatment in bladder
cancer: The European perspective.
Rodel C, Weiss C, Sauer R.
Combined modality therapy, including transurethral resection, radiation therapy,
and systemic chemotherapy, has been shown to produce survival rates comparable
to those of radical cystectomy. With these programs, cystectomy has been
reserved for patients with incomplete response or local relapse after
trimodality treatment. This review summarizes European series of combined
modality treatment of muscle-invasive bladder cancer and reflects our emphasis
on the importance of combining radiation with a transurethral resection and
cisplatin-based chemotherapy. It also documents our belief that high-grade T1
disease may be effectively treated by the same approach. This represents a true
distinction between the European and US strategies. We also review the role of
predictive and prognostic factors in selecting patients for the respective
treatment alternatives.

BACKGROUND: Despite recent progress in the treatment of advanced urothelial
cancer, there continues to be a need to identify new active agents and their
toxicity spectra. We conducted a study using FOLFOX-4 (oxaliplatin,
fluorouracil, folinic acid) in pre-treated advanced bladder cancer patients.
METHODS: Sixteen eligible patients with advanced disease were treated with
oxaliplatin (85 mg/m(3)) on day 1 followed by fluorouracil and folinic acid (De
Gramont schedule) on days 1 and 2 every 14 days until disease progression. All
patients received nutritional support to increase their caloric intake.
Objective responses and toxicity were evaluated. Biochemical responses
(reduction of markers) and nutritional parameters (increase in body weight and
albumin, and reduction in ferritin and C-reactive protein) were also considered.
RESULTS: Three patients obtained an objective response (overall response rate
19%). Hematological toxicity and stomatitis were the most commonly noted side
effects, but we observed only low (3-4) grade toxicity. In four patients (25%),
we observed a reduction in tumoral markers (carcinoembryonic antigen and
tissutal polypeptide antigen) and modified nutritional parameters. CONCLUSIONS:
Using these doses and schedules of FOLFOX-4 appears to be a promising therapy in
patients pre-treated with platinum compounds. More studies are required to
assess the possible role of this regimen in the treatment of advanced bladder
cancer.

Chemoradiotherapy as a bladder-preservation approach for
muscle-invasive bladder cancer: current status and perspectives.

790-0007, Japan. ysumiyos@shikoku-cc.go.jp
Radical cystectomy has been considered the gold standard for the treatment of
muscle-invasive bladder cancer. However, because of disappointing results with
radical surgery in terms of survival and decreased quality of life (QOL),
bladder-preservation treatment has been introduced as an alternative to radical
cystectomy. The primary purpose of the bladder-preservation approach has been to
maximize overall cure rates, with the secondary purpose being to preserve the
patient's bladder. The modalities used to ensure successful bladder preservation
include radical transurethral resection (TUR), concurrent cisplatin (CDDP)-based
chemotherapy, and radiotherapy. In patients who achieve a complete response (CR)
after trimodality therapy, 5-year survival rates of more than 50%, the same as
those of radical cystectomy, can be achieved and 70% of this group will retain
an intact functional bladder. In this article, bladder-preservation studies
using chemoradiotherapy are reviewed.

Bladder preservation protocols in the treatment of
muscle-invasive bladder cancer.

Cancer Center & Research Institute, Tampa, FL 33612 USA. torresjf@moffitt.usf.edu.
BACKGROUND: Over the last 3 decades, we have seen a paradigm shift in our
approach to the treatment of malignancy. During that time, organ conservation
protocols have become standard in the treatment of breast cancer, laryngeal
cancer, esophageal cancer, anal cancer and soft tissue sarcomas. METHODS: Data
from reports of bladder preservation protocols were reviewed to evaluate organ
preservation approaches in muscle-invasive bladder cancer. RESULTS: These trials
have shown equivalent disease control rates when compared to radical surgery,
with the advantage of organ function preservation. In spite of this, organ
preservation efforts in muscle-invasive bladder cancer have lagged behind this
overall trend in clinical oncology. However, efforts by several investigators
over the last 2 decades have shown that for a number of selected patients with
muscle-invasive bladder cancer, bladder preservation is feasible without an
apparent compromise of overall survival. CONCLUSIONS: Bladder preservation
therapy with a trimodality approach for a carefully selected patient population
is safe and effective. Formal randomized trials comparing radical cystectomy and
trimodality bladder-sparing therapy are justified.

Current Status of Radiation Therapy and Combined-Modality
Treatment for Bladder Cancer.
Rodel C.
Department of Radiation Therapy, University of Erlangen, Erlangen, Germany,
claus.roedel@strahlen.med.uni-erlangen.de.
BACKGROUND:. Standard treatment for muscle-invasive bladder cancer is radical
cystectomy. Combined-modality treatment (CMT), including transurethral resection
(TURBT), radiation therapy (RT) and systemic chemotherapy, has been shown to
produce survival rates comparable to those of radical cystectomy. With these
programs, cystectomy has been reserved for patients with incomplete response or
local relapse after trimodality treatment. METHODS:. This review summarizes
series of radical RT with different fractionation schedules and focuses on CMT
for muscle-invasive bladder cancer. Current protocols of the bladder-sparing
approach will be discussed and the background of future developments, including
incorporation of promising new chemotherapeutic agents as well as the role of
predictive and prognostic factors in selecting patients for the respective
treatment alternatives, will be given. RESULTS:. There is moderate evidence that
hyperfractionated and accelerated regimens are superior to conventional RT at
least in situations where no concomitant chemotherapy is applied. Several phase
II studies and one phase III study indicate that concomitant radiochemotherapy
is superior to RT alone. In modern series of CMT, 5-year survival rates in the
range of 50-60% have been published, and about three quarters of the surviving
patients maintained their own bladder. Recent data suggest that incorporation of
newer chemotherapeutic agents, particularly gemcitabine and taxanes, in CMT
protocols is feasible and promising. Clinical criteria helpful in determining
patients for bladder preservation include such variables as early tumor stage,
unifocal tumor, a visibly and microscopically complete TURBT, and absence of
ureteral obstruction. CONCLUSION:. CMT for bladder cancer is a reasonable
treatment option for patients who are deemed medically unfit for cystectomy and
for those seeking an alternative to radical cystectomy.

BACKGROUND & OBJECTIVE: Bladder cancer is the most common disease among
urogenital tumors, and poorly differentiated bladder transitional cell carcinoma
(BTCC) tends to recur, progress, and metastasize. This paper was to report our
experiences in intra-arterial chemotherapy as adjuvant and palliative therapy
for poorly differentiated BTCC. METHODS: Twenty-four patients with BTCC of grade
3 were treated with intra-arterial chemotherapy of GC regimen (gemcitabine plus
cisplatin). Among them, 21 had post-operative adjuvant intra-arterial
chemotherapy for 3 cycles, 3 advanced cases had palliative intra-arterial
chemotherapy for 6 cycles. RESULTS: All patients were followed-up for 6-20
months. The mean follow-up was 12 months for 21 patients received adjuvant
treatment, 1 developed pelvic metastasis, the others survived without evidenced
tumors. Of 3 advanced cases, 1 with CR survived disease-freely for 8 months; 1
with PR survived progression-freely for 6 months; 1 with PR died of tumor
relapse 13 months after chemotherapy. No serious complication was observed after
intra-arterial chemotherapy. CONCLUSIONS: Intra-arterial chemotherapy is
effective in managing poorly differentiated BTCC.

Immunotherapy for superficial bladder cancer.
Schenk-Braat EA, Bangma CH.
Department of Urology, Josephine Nefkens Institute, Room Be 362, PO Box 1738,
3000, DR Rotterdam, The Netherlands.
The treatment of superficial bladder cancer requires adjuvant therapies besides
transurethral resection because of a high recurrence rate after this standard
treatment alone. Current adjuvant therapies involve intravesical chemotherapy
for patients at low and intermediate risk for recurrence and progression, and
intravesical bacillus Calmette-Guerin for patients at intermediate and high
risk. However, these adjuvant therapies fail in a significant number of
patients, dictating the need for new and improved adjuvant treatment modalities
for superficial bladder cancer. Immunotherapy aiming at the modulation of the
immune system of the patient is a promising alternative adjuvant. This review
discusses the current status of the clinical development of various
immunotherapy approaches for superficial bladder cancer, including passive
immunotherapy, immune stimulants, immunogene therapy and cancer vaccination.

Prostatic capsule- and seminal-sparing cystectomy for bladder
carcinoma: initial results for selected patients.
Botto H, Sebe P, Molinie V, Herve JM, Yonneau L, Lebret T.
Department of Urology, Hopital Foch, Suresnes, France.
OBJECTIVE To evaluate the oncological outcome and functional results of
prostate-sparing cystectomy (PSC), proposed for treating bladder cancer, used
since 1999 in our institution in an attempt to preserve male sexuality and to
increase continence after cystectomy. PATIENTS AND METHODS Between January 1999
and December 2001, 111 men were candidates for cystectomy; 42 were selected for
a prostatic capsule- and seminal-sparing cystectomy with orthotopic urinary
diversion. All patients had clinically organ-confined tumours (clinical stage
</= T2, N0M0). The first stage of the procedure was a transurethral resection of
the prostate to exclude the involvement of transitional cell carcinoma (TCC) in
the prostate. RESULTS Eight patients were excluded from PSC because they had TCC
(seven) or prostate adenocarcinoma (one). The mean age of the remaining 34
patients was 61 years and all underwent PSC. After a mean follow-up of 26
months, seven patients (21%) had a recurrence; one developed a local recurrence,
there were widespread metastases in six (18%), and five had histologically
confirmed organ-confined tumour (T1-2N0M0). Rates for daytime and night-time
continence were 90% and 85%, and in 29 patients potency was unchanged.
CONCLUSION These early results suggest that PSC is not equivalent to radical
cystoprostatectomy for bladder cancer control, despite marked improvements in
the functional results. Moreover, in carefully selected patients this approach
appears to dramatically increase an unusually high metastasis rate. Therefore,
the indications for PSC should be either clearly well defined or abandoned in
these patients.

Salvage cystectomy after failure of interstitial radiotherapy and
external beam radiotherapy for bladder cancer.
Nieuwenhuijzen JA, Horenblas S, Meinhardt W, van Tinteren H, Moonen LM.
Department of Urology, The Netherlands Cancer Institute/Antoni van Leeuwenhoek
Hospital, Amsterdam, The Netherlands.
OBJECTIVE: To evaluate the long-term results of salvage cystectomy after
interstitial radiotherapy (IRT) and external beam radiotherapy (EBRT) for
transitional cell carcinoma, and to assess the morbidity and functional results
of the different urinary diversions used. PATIENTS AND METHODS: The records of
27 patients treated with salvage cystectomy in one institution between 1988 and
2003 were retrospectively analysed. RESULTS: Salvage cystectomy was used after
failure of IRT in 14 or EBRT in 13 patients, with a 3- and 5-year survival
probability of 46% (95% confidence interval 26-65) and 33 (11-54)%. The 5-year
overall survival after cystectomy was 54% after IRT and 14% after EBRT (P =
0.12). Tumour category, response to radiation, American Society of
Anesthesiology score, and complete tumour resection had a significant influence
on survival. Five of seven patients with incomplete resection died because of
local disease, with a median survival of 5 months. There was clinical
understaging after radiotherapy in 41% of patients. Nine patients had an
orthotopic neobladder, with complete day- and night-time continence in eight and
four, respectively. All patients but one had good voiding function. There were
early complications in two and late complications in six patients (for Bricker,
seven of 14 and none; for Indiana, none of four and two of four). The duration
of hospitalization was not influenced by the type of diversion. Erectile
function was maintained in four of six patients after a sexuality-preserving
cystectomy and neobladder. CONCLUSIONS: Salvage cystectomy can be performed with
acceptable morbidity using any type of urinary diversion. Understaging after
radiotherapy is common, but preoperative selection needs improving. A very
significant factor for an adverse outcome and death from local tumour recurrence
was incomplete resection, suggesting that salvage cystectomy should only be
attempted if complete resection is probable.

Effective bladder sparing therapy with intra-arterial cisplatin
and radiotherapy for localized bladder cancer.
Eapen L, Stewart D, Collins J, Peterson R.
Department of Radiation Oncology, The Ottawa Hospital, Ottawa, Ontario, Canada.
PURPOSE: We evaluated the feasibility and efficacy of the organ preserving
strategy of intra-arterial cisplatin and concurrent radiotherapy for localized
bladder cancer. MATERIALS AND METHODS: Bladder preservation has been pursued
over the decades in treatment regimens featuring radiotherapy alone or in
conjunction with single or multiagent chemotherapy. The chemotherapy has
consisted almost exclusively of intravenously administered drugs. There are
theoretical and clinical data demonstrating a higher concentration of cisplatin
within tumors following intra-arterial as opposed to intravenous delivery. This
study was performed to evaluate whether this increased concentration would
enhance radiosensitization and thereby increase the success of bladder
preservation. RESULTS: We report on our prospectively collected experience
during 15 years of treating 200 patients with localized bladder cancer using
this regimen of 3 courses of intra-arterial cisplatin integrated with pelvic
radiotherapy and reserving cystectomy for salvage as required. We report on the
efficacy in terms of complete response rate, ultimate tumor-free bladder
preservation, overall survival and patterns of failure. We detail the acute and
chronic toxicity observed to date. CONCLUSIONS: This strategy has resulted in a
durable high complete response rate and overall tumor-free bladder preservation
rate of 75% while maintaining a survival comparable to that achieved with
cystectomy. These results corroborate the hypothesis that intra-arterial
administration of cisplatin enhances radiosensitization during pelvic
radiotherapy.

Cancers of the bladder.
Sengupta N, Siddiqui E, Mumtaz FH.
Department of Urology, Chase Farm Hospital, The Ridgeway, Enfield EN2 8JL,
England.
Bladder cancer is the fifth most common malignancy in Europe and the fourth most
common malignancy in the United States. It affects one in 4000 people and
accounts for 5% of all diagnosed cancers. The peak incidence is in the fifth and
seventh decade. There is a strong association between smoking and bladder
cancer. Smokers have a fourfold higher incidence of developing bladder cancer
than the general population. The disease has a spectrum of clinical severity
varying from superficial bladder cancer to muscle invasive or metastatic disease
which carries a poor prognosis. Currently the superficial form of the disease is
managed by endoscopic resection of the tumour, often followed by the
instillation into the bladder of cytotoxic agents. Due to the tendency of
bladder cancer to recur repeated cystoscopies and resections are often required.
Because of this, one of the main thrusts of research is to find a way of
preventing the progression from superficial disease to muscle invasive and
metastatic bladder cancer.

OBJECTIVE: The study aimed at evaluating the activity and toxicity of
gemcitabine monochemotherapy in a unselected series of elderly patients with
advanced bladder cancer. The secondary objectives were to establish whether
there is a correlation between treatment and Comprehensive Geriatric Assessment
(CGA) and, in addition, to determine overall patient survival. METHODS:
Treatment consisted of six courses of chemotherapy with gemcitabine at a dosage
of 1,200 mg/m2 on days 1 and 8, every 21 days. CGA, as described by Gruppo
Italiano di Oncologia Geriatrica, was assessed for evaluating the functional
status of patients before, during, and after treatment. RESULTS: Twenty-five
patients were enrolled (M/F 22/3), 22 of these were evaluable for response and
23 for toxicity. Characteristics of patients: median age 76 years (range 71-87);
ECOG performance status (PS) 1 in 12 patients and 2 in 13 patients; clinical
stage III in 6 patients and IV in 19 patients. At the end of the therapy the
parameters of CGA improved in 4 cases (17%), remained unchanged in 17 cases
(74%) and worsened only in 2 cases (9%). Two patients were not evaluable.
Response evaluation showed 3 (13.5%) complete responses (CRs) and 7 (32%)
partial responses (PRs), for an overall response rate of 45.5% [95% confidence
interval (CI), 24.3-65.7%]. Three (13.5%) patients had stable disease (SD ) and
9 (41%) disease progression (DP). Median overall survival was 8 months and
median time to progression was 5 months. Treatment was generally well tolerated,
with 1 patient having grade 3 gastrointestinal toxicity and 3 having grade 4
neutropenia. CONCLUSIONS: We conclude that gemcitabine can be safely
administered in monochemotherapy, is effective and does not worsen the
functional status of elderly patients with advanced bladder cancer. Copyright

Partial cystectomy: a contemporary review of the Memorial
Sloan-Kettering Cancer Center experience and recommendations for patient
selection.

Dalbagni G, Sogani PC.
Department of Urology, Memorial Sloan-Kettering Cancer Center, 353 E. 68th
Street, New York, NY 10021, USA.
PURPOSE: Partial cystectomy is a bladder sparing procedure that has been used to
treat invasive bladder cancer in highly selected patients. This study analyzes
the outcomes of partial cystectomy in a contemporary cohort of patients to
identify appropriate selection criteria for the procedure. MATERIALS AND
METHODS: Records were reviewed for 58 patients with a primary bladder tumor who
had undergone partial cystectomy at Memorial Sloan-Kettering Cancer Center from
1995 to 2001. Information was collected on tumor size, histology, location,
presence of carcinoma in situ (CIS), multifocality, neoadjuvant treatment,
clinical stage, pathological stage and disease status. RESULTS: For the 58
patients analyzed, overall 5-year survival was 69% with a mean followup of 33
months (range 1 to 83). Of the patients 43 (74%) are alive with an intact
bladder, 39 (67%) are currently disease-free with an intact bladder and 32 (55%)
have been continuously disease-free with an intact bladder. Seven patients
experienced a superficial recurrence and were treated successfully while 15
patients experienced an advanced recurrence. On univariate analysis CIS and
multifocality were related to superficial recurrence, and lymph node involvement
and positive surgical margin were related to advanced recurrence. On
multivariate analysis concomitant CIS (odds ratio 7.05, p = 0.004) and lymph
node involvement (odds ratio 4.38, p = 0.031) were predictors of advanced
recurrence. CONCLUSIONS: In highly selected patients with invasive bladder
cancer, partial cystectomy offers acceptable outcomes. Concomitant CIS and
presence of metastases to regional lymph nodes predict advanced recurrence.

Athens, Greece.
Objectives: Neoadjuvant chemotherapy has been used to improve outcome after
cystectomy or for selection for bladder preservation in patients with bladder
cancer. We have shown encouraging results using docetaxel and cisplatin in
patients with advanced urothelial cancer. We are reporting the results of a
phase II study using this combination as neoadjuvant treatment in patients with
muscle invasive bladder cancer. Methods: Fifty patients were treated with
docetaxel and cisplatin at 75mg/m(2) every 3 weeks for 3 cycles prior to
cystectomy. Median follow-up was 70.2 months. Results: Chemotherapy was well
tolerated. 5-year survival and progression-free survival (PFS) were 51.92% (95%
confidence intervals [CI]: 37.76-66.08) and 52.47% (95%CI: 37.99-66.95).
Multivariate analysis showed that clinical stage (cT) <== 3a was associated with
improved 5-year survival (86.42% vs. 40.81%, [Formula: see text] ). Forty one
patients underwent cystectomy. No tumor was found in 15 cases (36.6%). 5-year
survival was 60.34% (95%CI: 52.2-68.48) and PFS was 57.11% (95%CI: 41.29-72.93).
Absence of residual tumor was associated with improved 5-year survival (93.33%
vs. 40.72%, [Formula: see text] ). Conclusions: Neoadjuvant chemotherapy with
docetaxel and cisplatin is feasible and produced high pathological complete
remission rate and excellent outcome in patients with no residual tumor.

Phase II Study to Investigate the Ablative Efficacy of
Intravesical Administration of Gemcitabine in Intermediate-Risk Superficial
Bladder Cancer (SBC).

Department of Medical Sciences, Urology Clinic, University of Piemonte Orientale,
Via Solaroli, 17, 28100 Novara, Italy.
Objective: Phase I studies have so far demonstrated that intravesical
Gemcitabine up to a 40mg/ml concentration is well tolerated and has a
substantial ablative activity on high-risk BCG refractory SBC. New treatment
options are needed for intermediate-risk SBC recurring after conventional
intravesical treatments. The purpose of the present study was to investigate the
ablative efficacy of intravesical Gemcitabine on intermediate-risk SBC. Methods:
The study was designed as a two-stage phase II trial, with a sample size of 39
patients. The efficacy of intravesical Gemcitabine at a concentration of 40mg/ml
(2000mg in 50ml saline solution) administered weekly for 6 weeks was assessed on
a single marker tumour left in the bladder after a complete TUR of all other
lesions. Patients underwent TUR or biopsy at the site of the marker lesion 2
weeks after completion of the treatment. Results: Complete response was observed
in 22 out of 39 patients (56%). No progression was observed among the 17
non-responders. Neither systemic nor local side effects generally exceeded grade
I toxicity. Conclusion: The ablative effect of Gemcitabine produced a higher
number of responses than the minimum required by the protocol to indicate a
significant probability of drug efficacy. It is worth testing the drug in phase
III trials to assess for durability of response.

Novel therapeutics in the treatment of bladder cancer.
Shah JB, McKiernan JM.
Department of Urology, Columbia University Medical Center, New York, NY 10032,
USA.
PURPOSE OF REVIEW: The successful treatment of bladder cancer remains a
challenge for urologists and oncologists. There have been substantial changes in
the therapeutic options for the management of both superficial and
muscle-invasive bladder cancer in the last 5 years. Here we review the
preclinical and clinical developments over the last year in bladder cancer
therapeutics. RECENT FINDINGS: There is a growing trend toward the use of
multimodal treatments for all bladder cancers. For superficial disease,
intravesical instillation of chemotherapeutic agents after transurethral
resection is quickly becoming the standard of care. Novel therapeutic modalities
under investigation include DNA vaccines, magnetically targeted carriers,
bio-adhesive microspheres and antisense oligodeoxynucleotides. For
muscle-invasive bladder cancer, systemic perioperative chemotherapy is being
used with increasing frequency and the latest preclinical research efforts are
focused on the inhibition of angiogenesis and other processes predisposing to
metastatic disease. SUMMARY: Treatment goals for bladder cancer of any stage are
complete removal of the initial tumor, prevention of disease recurrence and
effective inhibition of progression to advanced disease with the ultimate aim of
reducing mortality. The myriad novel therapeutic modalities currently being
explored suggest that these goals may perhaps be achievable within our lifetime.

Second-line intravesical therapy versus cystectomy for bacille
Calmette-Guerin (BCG) failures.
Joudi FN, O'Donnell MA.
University of Iowa Department of Urology, Iowa City, Iowa, USA.
PURPOSE OF REVIEW: To give an update on the new modalities in treating patients
with superficial bladder cancer who have failed bacille Calmette-Guerin. RECENT
FINDINGS: The addition of interferon to bacille Calmette-Guerin has proven to be
an effective combination therapy for bacille Calmette-Guerin failures.
Electromotive intravesical mitomycin C as well as local microwave hyperthermia
have been shown to improve drug delivery and increase response rates.
Intravesical gemcitabine has shown some promising results in phase I studies and
is being investigated in phase II trials. Photodynamic therapy is proposed as a
second-line therapy for bacille Calmette-Guerin failures. SUMMARY: New treatment
modalities are being introduced and existing ones improved to treat bacille
Calmette-Guerin-refractory superficial bladder cancer. These agents need to be
studied in large randomized trials. Until these agents prove to decrease
recurrence rates and delay progression of high-risk superficial bladder cancer,
cystectomy remains the standard of care for the patient who is a good surgical
candidate and willing to undergo such major surgery.

Old friends, new ways: revisiting extended lymphadenectomy and
neoadjuvant chemotherapy to improve outcomes.
Busby JE, Evans CP.
Department of Urology, University of California, Davis, Sacramento, CA 95817,
USA.
PURPOSE OF REVIEW: Standard therapy for muscle-invasive bladder cancer is
radical cystectomy and pelvic-lymph-node dissection. Because 50% of patients
will die at 5 years as a result of micrometastases, improvements have been
sought to increase the survival rates. Two specific approaches include
administration of neoadjuvant chemotherapy or extending the boundaries of the
lymph-node dissection. We reviewed the current literature to define present
trends and studies that involve these adjunct treatments. RECENT FINDINGS: The
benefits of extended lymphadenectomy have been demonstrated by several groups.
These include mapping nodal metastatic sites and defining the requisite number
of nodes removed to optimize survival. Though not universal, it is frequently
concluded that increasing the number of nodes removed improves survival without
worse morbidity. Neoadjuvant chemotherapy has been proposed to eliminate occult
cancer cells outside the margins of resection. Results have been variable and
modest, though emerging data from the Southwest Oncology Group may further
support such an approach and improve organ preservation. SUMMARY: Extended
lymphadenectomy has consistently shown benefit with minimal morbidity and should
be considered - especially in cystectomy patients that are T3. The results from
neoadjuvant chemotherapy are more modest. Further studies await further
elucidation to confirm this.

Aggressive treatment for bladder cancer is associated with
improved overall survival among patients 80 years old or older.

OBJECTIVES: To examine the impact of various treatment modalities on survival
among patients with bladder cancer who were 80 years old or older compared with
younger patients. A compendium of evidence suggests that bladder cancer surgery
is safe among octogenarians; however, the benefit of such treatment in a
population with limited life expectancy has not been well documented. METHODS:
Subjects with the primary diagnosis of bladder cancer were identified from the
National Cancer Institute's Surveillance, Epidemiology, and End Results cancer
registry between 1988 and 1999. Of the 13,796 patients diagnosed with bladder
cancer, 24% were older than 80 years of age. Proportional hazards regression
modeling was performed to determine the independent association of treatment
strategy on overall and bladder cancer survival while adjusting for multiple
covariates. RESULTS: Of patients 80 years old or older, bladder cancer
management included watchful waiting (7%), radiotherapy alone (1%), full or
partial cystectomy (12%), and transurethral resection (79%). Patients 80 years
old or older were less likely to be treated with extirpative surgery than their
younger counterparts (P <0.0001). Cox proportional hazards models demonstrated
that, among patients 80 years old or older, radical cystectomy/partial
cystectomy had the greatest risk reduction in death from bladder cancer (hazard
ratio 0.3) and death from any cause (hazard ratio 0.4) among the primary
treatment modalities (both P <0.0001). CONCLUSIONS: Disparities in practice
patterns between younger and geriatric patients with bladder cancer exist. We
provide compelling evidence that aggressive surgical management of bladder
cancer in these patients may improve survival. Risk adjustment tools should be
used to identify patients (young and old) who would be better served by less
aggressive management.

Low dose BCG as adjuvant therapy for superficial bladder cancer
and literature review.
Cheng CW, Ng MT, Chan SY, Sun WH.
Department of Surgery, Alice Ho Miu Ling Nethersole Hospital, Tai Po, Hong Kong,
China.
Background: Bacillus Calmette-Guerin (BCG) at low doses has long been employed
as prophylactic and therapeutic treatment for superficial cancer of the urinary
bladder, aiming at reducing toxicity while maintaining efficacy. A retrospective
review was reported, together with a review of the literature with respect to a
low dose BCG regimen. Methods: Forty-five consecutive patients with superficial
bladder cancer (Ta or T1) with one or more of the appropriate criteria (grade
above 1, stage above a, size >1 cm, multiple or recurrent), after complete
transurethral resection, received 27 mg Connaught strain BCG weekly for 6 weeks.
There was no maintenance therapy. Patients were evaluated with urine cytology
and cystoscopy. Recurrence, progression and death were analysed. Results: With a
median follow up of 14 (range 3-61) months, 24 (53%) of the 45 patients
responded to one course of 6 weekly BCG without recurrence. A further group of
13 (29%) patients responded to a second course of BCG on recurrence. Disease
progressed in one (2.2%) patient. Two (4.4%) patients died of an unrelated
condition. There was no disease specific mortality. Side-effects were common but
well tolerated, with only two (4.4%) cases of treatment interruption.
Conclusions: Low dose BCG could be an alternative option of adjuvant therapy for
superficial bladder cancer with acceptable toxicity and good compliance.

Combined-modality therapy with gemcitabine and radiotherapy as a
bladder preservation strategy: results of a phase I trial.
Kent E, Sandler H, Montie J, Lee C, Herman J, Esper P, Fardig J, Smith DC.
Department of Internal Medicine, University of Michigan School of Medicine and
Comprehensive Cancer Center, AnnArbor, 48109, USA.
PURPOSE: We conducted a phase I trial of gemcitabine given twice weekly with
concurrent radiotherapy in patients with muscle-invasive bladder cancer.
PATIENTS AND METHODS: Eligible patients underwent maximal transurethral
resection of their bladder tumors followed by twice-weekly infusion of
gemcitabine with 2 Gy/d concurrent radiotherapy to the bladder, for a total of
60 Gy over 6 weeks. The starting dose of gemcitabine was 10 mg/m(2) with
subsequent dose levels of 20, 27, 30, and 33 mg/m(2). The primary end point was
the determination of the maximum-tolerated dose (MTD) of twice weekly
gemcitabine with concurrent radiotherapy. Secondary end points included
assessment of toxicity associated with combined-modality therapy and initial
assessment of the rate of bladder preservation. RESULTS: Twenty-four patients
were enrolled and 23 were assessable for toxicity and response. No significant
toxicity was demonstrated at the 10 or 20 mg/m(2) twice-weekly doses.
Dose-limiting toxicity (DLT) occurred in two of three patients treated at 33
mg/m(2). Intermediate dose levels of 27 and 30 mg/m(2) were then evaluated. The
MTD of gemcitabine was 27 mg/m(2). The DLT was systemic, manifested as an
elevation in liver function tests, malaise, and edema. Fifteen of 23 patients
(65%) are alive with bladders intact and no evidence of recurrent disease at a
median follow-up of 43 months. CONCLUSION: Twice-weekly gemcitabine with
concurrent radiotherapy at 2 Gy/d to a total dose of 60 Gy is well-tolerated.
The MTD of gemcitabine is 27 mg/m(2). There is a high rate of bladder
preservation in this selected group of patients.

The evolving role of pelvic lymphadenectomy in the treatment of
bladder cancer.
Sanderson KM, Stein JP, Skinner DG.
Department of Urology, USC Norris Cancer Center, Los Angeles, CA, USA.
Regional lymphadenectomy is integral to the surgical management of high-grade
invasive bladder cancer. A growing body of evidence suggests that a lymph node
dissection may provide not only improved prognostic information, but also a
clinically significant therapeutic benefit for both lymph node positive and
negative patients undergoing radical cystectomy. While the inclusion of lymph
node resection in conjunction with radical cystectomy for patients with
clinically negative nodes is well accepted, the extent of the nodal dissection
remains highly contentious. Similarly, the benefit of node dissection for
patients with advanced disease and gross adenopathy or for those with
superficial disease (Ta, T1 or TIS) remains a topic of heated debate. This
review describes the historical evolution of lymphadenectomy in the surgical
treatment of bladder cancer and provides a comprehensive review of the current
literature addressing the role of lymph node dissection in the treatment of
bladder cancer.

Bladder cancer.
Borden LS Jr, Clark PE, Hall MC.
Department of Urology, Wake Forest University School of Medicine,
Winston-Salem, North Carolina, USA.
PURPOSE OF REVIEW: This article reviews recent advances in
the diagnosis and management of bladder cancer. RECENT FINDINGS:
Bladder cancer is a significant cause of morbidity and mortality.
Recent research has attempted to improve the care of patients
with this disease. Evidence suggests that bacillus Calmette-Guerin
is the most effective intravesical therapy for the treatment of
superficial bladder cancer and that maintenance therapy is superior
to an induction course alone. In patients with muscle-invasive
disease, nodal status and extent of lymphadenectomy have been
shown to correlate with survival after radical cystectomy. The
role of chemotherapy in the treatment of bladder cancer continues
to evolve as well. Neoadjuvant chemotherapy has recently demonstrated
a survival benefit, and trials are ongoing to define the optimal
regimen of chemotherapy for urothelial carcinoma. SUMMARY: Improved
understanding and advancements in the management of all stages
of bladder cancer continue to improve the care of patients with
this disease.

Institute H. San Raffaele, Milan, Italy. colombo.renzo@hsr.it
PURPOSE: We assessed postoperative clinical outcomes such as
day and nighttime urinary continence and overall sexual function
in patients who underwent nerve and seminal sparing cystectomy
with ileocapsuloplasty compared with patients after standard cystoprostatectomy
with similar orthotopic urinary reservoir. MATERIALS AND METHODS:
A total of 27 patients (mean age 52 years, range 36 to 61) with
superficial high risk or muscular invasive T2 bladder cancer underwent
radical nerve and seminal sparing cystectomy with ileocapsule
anastomosis. Postoperative clinical outcomes such as urinary continence,
voiding patterns and urodynamic parameters were evaluated at 3,
6 and 12 months, while overall sexual function was determined
at baseline and at 6 and 12-month followup. RESULTS: Nerve and
seminal sparing cystectomy provides better outcomes in terms of
urinary and urodynamic parameters compared to standard cystoprostatectomy.
Furthermore, fully normal postoperative erectile function and
satisfactory overall sexual quality of life were documented at
early and delayed followup in all patients. A retrograde ejaculation
with reliable sperm retrieval from urine was also documented.
CONCLUSIONS: Although these findings need to be confirmed in a
larger patient population, when respecting rigorous patient selection
criteria and careful postoperative surveillance, nerve and seminal
sparing cystectomy seems to offer satisfactory clinical and functional
outcomes. From an oncological point of view, long-term followup
is of paramount importance to confirm whether this surgical procedure
can be proposed as a valid choice of treatment for young, fully
potent and socially active patients with organ confined bladder
cancer.

Combined chemotherapy and external beam radiotherapy
for transitional cell carcinoma of the bladder.
Ennis RD.
Department of Radiation Oncology, College of Physicians and Surgeons
of Columbia University, 622 West 168th Street, BHN-Room B11, New
York, NY 10032, USA. rde5@columbia.edu
A growing body of evidence supports the treatment of invasive
transitional cell carcinoma of the bladder with transurethral
resection, chemotherapy, and external beam radiotherapy. Randomized
trials have demonstrated the superiority of chemotherapy plus
radiotherapy to radiotherapy alone. Several series with 10 years
of follow-up demonstrate that the success of this approach can
be maintained. Preservation of the urothelium, however, results
in continued risk of de novo bladder cancer development in addition
to the possibility of recurrence. Thus, continued close surveillance
and treatment of subsequent superficial or invasive bladder cancer
is an essential component of this bladder preservation approach.
Concomitant cisplatin chemotherapy and radiotherapy or initial
(neoadjuvant) combination cisplatin-based chemotherapy followed
by radiotherapy are the two options best supported by the literature.
How these regimens compare with each other and with cystectomy-based
treatment remains to be defined.

A Phase II study of gemcitabine and cisplatin
in chemotherapy-naive, unresectable gall bladder cancer.
Doval DC, Sekhon JS, Gupta SK, Fuloria J, Shukla VK, Gupta
S, Awasthy BS.
1Rajiv Gandhi Cancer Institute & Research Center, Delhi, India.
The primary objective of this study was to determine the response
rates of the gemcitabine and cisplatin combination in unresectable
gall bladder cancer patients. The secondary objectives were to
evaluate the toxicity, time to progressive disease, and overall
survival. Chemonaive patients with histologically proven, unresectable
bidimensionally measurable gall bladder cancer were enrolled into
this study. All patients were required to have a Zubrod's performance
status </=2, no prior radiotherapy, and adequate major organ
function. Patients received gemcitabine (1000 mg m(-2) intravenously
over 30-60 min) on days 1 and 8, and cisplatin (70 mg m(-2) intravenously
over 2 h) on day 1, every 21 days. Response assessment was done
by a CT scan after every other cycle of chemotherapy. In all,
30 patients were eligible for efficacy and toxicity analysis.
There were four (13.3%) complete responders, seven (23.3%) partial
responders, and seven (23.3%) with stable disease, with four (13.2%)
patients showing disease progression. The median time to progression
was 18 weeks (95% confidence interval (CI) 14-24 weeks), and the
median duration of response was 13.5 weeks (range 5.5-104 weeks).
The median overall survival was 20 weeks (95% CI 14-31 weeks),
with 1-year survival rate of 18.6%. WHO grade 3 or 4 anaemia was
seen in seven (23.3%) and four (13.3%) patients, respectively.
Five (16.6%) patients each experienced grade 3 or 4 neutropenia,
and grade 3 or 4 thrombocytopenia was seen in three (10%) and
two (6.6%) patients, respectively. The present study shows that
gemcitabine/cisplatin combination is well tolerated and active
in advanced unresectable gall bladder cancer.British Journal of

Section of Laparoscopic and Minimally Invasive Surgery, Glickman
Urological Institute, Cleveland Clinic Foundation, 9500 Euclid
Avenue, Cleveland, OH 44195, USA.
PURPOSE OF REVIEW: The laparoscopic approach in urology is
now an accepted option for kidney, adrenal, and prostate surgery.
We review the current experience with laparoscopic radical cystectomy
to identify its role in oncological bladder surgery. RECENT FINDINGS:
Pure laparoscopic techniques are being employed for the extirpative
portion of laparoscopic radical cystectomy at multiple institutions.
Various extracorporeal and intracorporeal techniques are evolving
for the reconstructive procedures necessary for urinary diversion.
Worldwide experience continues to accumulate with over 150 cases
already having been performed. SUMMARY: With the gradual growth
and experience in laparoscopic radical cystectomy, along with
continuing refinements in technique, laparoscopic radical cystectomy
is now being performed at many centers worldwide. Long-term oncological
and functional outcome data are necessary to determine its proper
role for patients with bladder cancer.

Departments of Urology and Surgery, University of California,
San Francisco, California 94143, USA. vmaster@urol.ucsf.edu
PURPOSE: Optimal management and clinical outcome of bladder
cancer in renal transplant recipients are not well-defined. We
analyzed single institution treatment strategies and outcomes
of these patients. MATERIALS AND METHODS: We retrospectively reviewed
the University of California, San Francisco transplant database
which contains information on 6,288 renal transplants performed
between 1964 and 2002. The United Network for Organ Sharing database
and Israel Penn International Transplant Tumor Registry were also
queried to characterize the global nature of bladder cancer in
renal transplant recipients. RESULTS: The United Network for Organ
Sharing database (1986 to 2001) contained information on 31 patients
who were found to have bladder cancer (0.024% prevalence) and
the Israel Penn International Transplant Tumor Registry (1967
to 2001) contained information on 135 patients representing 0.84%
of all reported malignancies. We identified 7 renal transplant
recipients with bladder cancer at our institution. Invasive transitional
cell carcinoma developed in 5 patients at a median of 2.8 years
after transplant. Three patients underwent uncomplicated radical
cystectomy and preservation of the renal allograft. Overall survival
at 48 months was 60%. CONCLUSIONS: Bladder cancer after renal
transplantation is not common. For patients who present with invasive
disease, traditional extirpative surgery should be considered.
Moreover, the allograft is rarely the source of transitional cell
carcinoma and can be preserved. In our experience the cancer and
urinary outcomes compare favorably with nontransplant patient
outcomes after treatment.

Immunotherapy for urological malignancies.
Krejci KG, Markiewicz MA, Kwon ED.
Department of Urology, Mayo Clinic, Rochester, Minnesota 55905,
USA.
PURPOSE: For decades urologists have successfully used immunotherapy
in the battle against cancer. Interleukin-2 in renal cell carcinoma
and bacillus Calmette-Guerin in bladder cancer are standard primary
and/or adjunctive therapies for these diseases. Recent advances
in our understanding of mechanisms governing immune system activation
have fostered a myriad of novel immunotherapeutic approaches that
show great promise in vivo but have had limited success in human
trials to date. This review highlights current immunotherapy strategies
that may prove to be successful treatments for urological cancers.
MATERIALS AND METHODS: We performed a MEDLINE literature search
for articles relating to immunotherapy in bladder, prostate and
renal cell carcinoma in animals and humans. We included the most
promising developments in this review. RESULTS: In addition to
combining existing therapies to improve their efficacy, novel
approaches that attempt to exploit the immune system ability to
identify, target and eradicate malignancies are now being developed.
These therapies include the use of antitumoral monoclonal and
bi-specific antibodies, manipulation of T-lymphocyte costimulatory
molecules and the administration of newly discovered cytokines
as well as the development of antitumor vaccines. CONCLUSIONS:
To date the full potential of immunotherapy for the treatment
of urological malignancies has not been recognized. As our knowledge
of the immune system expands, so too may our ability to manipulate
it to affect tumor regression. This review describes the most
recent and most promising developments in immunotherapy for urological
malignancies.

Farnesyltransferase inhibitors.
Sebti SM, Adjei AA.
The farnesyltransferase inhibitors (FTIs) were designed to
inhibit the post-translational processing of Ras proteins, which
are mutated in 30% of all human cancers. Recent studies suggest,
however, that the target of FTIs may be a protein other than Ras,
and that these agents may be more appropriately used to treat
tumors with activated wild-type ras signaling. Preliminary results
from several phase II and phase III studies have been reported.
The FTIs fail to show significant single-agent activity in non-small
cell lung cancer, small cell lung cancer, pancreatic cancer, refractory
colorectal cancer, and bladder cancer. Activity has been shown
in hematologic malignancies (acute myeloid leukemia, chronic myeloid
leukemia, myelodysplastic syndrome), breast cancer, and glioma.
Several combination studies of FTIs and standard cytotoxic agents
are ongoing.

INTRODUCTION: Superficial bladder cancer can be treated by
transurethral resection and additional intravesical therapy. Although
agents like Mitomycin C, Epirubicin and BCG are routinely used,
there is a need for more potent and/or less toxic agents. Gemcitabine
is a deoxycytidine analogue, used systemically for several tumours,
such as non-localised bladder cancer, where it is effective and
well tolerated. We investigated the use of three dose levels of
gemcitabine when given intravesically in humans for safety and
pharmacokinetic research. MATERIAL AND METHODS: Patients with
superficial bladder cancer, except pT1G3 or CIS were included.
Six weekly instillations of 1000, 1500 or 2000 mg gemcitabine
were given in 50 ml saline for one hour. Dose modifications were
defined in case of dose limiting toxicities. Blood samples were
taken before, and 5, 30, 60 (= evacuation) and 120 minutes after
instillations 1, 3 and 6. Samples were used for blood counts and
pharmacokinetics. Side effects were noted. RESULTS: 3, 4 and 3
patients were treated with 1000, 1500, and 2000 mg gemcitabine
respectively, of which 2, 3 and 1 patients had highly recurrent
tumours before treatment. Seven patients experienced side effects:
2 with dysuria after the first instillation, 2 after instillations
3-6 and 4-6 and in 3 patients headache, fatigue and heavy legs
were experienced once. All side effects were reversible, non-limiting
and WHO 1. No macroscopic hematuria was seen. Haematology showed
only one case of drop in white blood cell count (lowest dose level,
after the first instillation). Gemcitabine plasma levels were
immeasurable or low, with peak levels between 30 and 60 minutes,
decreasing after more instillations. The metabolite difluorodeoxyuridine
reached levels of at most 5 microM, indicating a very low passage
of the drug to the systemic circulation. CONCLUSION: Intravesical
gemcitabine in the dose used has minimal and reversible side effects.
Plasma evaluation indicates that its intravesical use is safe.

Surgical management of infiltrating bladder cancer
in elderly patients.

Department of Urology, Cochin Hospital, 27 rue du Faubourg Saint
Jacques, 75014 Paris, France. michael.peyromaure@cch.ap-hop-paris.fr
OBJECTIVES: To review the surgical therapeutic options in elderly
patients with infiltrating bladder cancer. METHODS: A review of
the literature relevant to cystectomy and transurethral resection
for infiltrating bladder cancer in elderly patients was conducted
using Medline Services. RESULTS: Thanks to progress in anaesthesia,
intensive care and surgery, cystectomy now forms part of the classical
treatments for bladder cancer in elderly patients, with acceptable
mortality and morbidity rates. The recent series of cystectomies
performed in patients over 75 years old report a mortality rate
associated with the procedure of less than 4.5%. The global mortality
rate in the same population ranges from 10 to 50%. These rates
are now similar to those reported in the general population. The
mean survival after cystectomy in patients over 75 years old is
more than 2 years. Global survival at 5 years is between 37 and
68%. It is acknowledged by most authors that resection alone is
associated with higher relapse and progression rates than cystectomy.
CONCLUSIONS: Cystectomy appears to be reasonable in elderly people
who have a life expectancy of more than 2 years, provided that
a rigorous pre-operative assessment and anaesthetic management
are performed. Transurethral resection alone should be proposed
only to patients with poor health status and/or very advanced
age.

PURPOSE: Despite local therapy most patients with muscle invasive
transitional cell carcinoma (TCC) of the bladder die of systemic
relapse, indicating a need for effective adjunctive systemic treatment.
We determined whether neoadjuvant chemotherapy improved overall
survival. MATERIALS AND METHODS: A systematic review and meta-analysis
were performed of all known randomized controlled trials (RCTs)
of neoadjuvant chemotherapy for stages II and III TCC conducted
between 1984 and 2002. RESULTS: A total of 16 eligible RCTs (3,315
patients) were identified. Of these trials 11 (2,605 patients)
provided data suitable for a meta-analysis of overall survival
and the pooled HR was 0.90 (95% CI 0.82 to 0.99, p = 0.02). Eight
trials used cisplatin based combination chemotherapy and the pooled
HR was 0.87 (95% CI 0.78 to 0.96, p = 0.006), consistent with
an absolute overall survival benefit of 6.5% (95% CI 2 to 11%)
from 50% to 56.5%. Reported progression-free survival data were
insufficient for meta-analysis but they appeared concordant with
overall survival results. Mortality due to combination chemotherapy
was 1.1%. A major pathological response was associated with improved
overall survival in 4 trials.CONCLUSIONS Neoadjuvant cisplatin
based chemotherapy improves overall survival in muscle invasive
TCC. The size of the effect is modest and combination chemotherapy
can be administered safely without adverse outcomes resulting
in delayed local therapy. An optimal chemotherapy regimen was
not identified and newer regimens have not been tested in RCTs
in this setting. Further efforts to identify the patients most
likely to benefit from neoadjuvant therapy are necessary to optimize
its use.

Concurrent chemoradiotherapy for clinical stage
T2 bladder cancer: report of a single institution.
Peyromaure M, Slama J, Beuzeboc P, Ponvert D, Debre B,
Zerbib M.
Department of Urology, Cochin Hospital, Paris, France.
OBJECTIVES: To report our experience with concurrent chemoradiotherapy
for clinical Stage T2 bladder cancer. METHODS: From 1996 to 2002,
43 patients were treated with concurrent chemotherapy and radiotherapy
for clinical Stage T2 bladder cancer. After complete bladder transurethral
resection, all patients underwent chemotherapy, consisting of
one daily infusion of cisplatin at a dose of 15 mg/m2 and 5-fluorouracil
at a dose of 400 mg/m(2) on days 1 to 3 (first cycle) and days
15 to 17 (second cycle). Pelvic irradiation was administered at
a dose of 24 Gy, using two daily fractions of 3 Gy on days 1,
3, 15, and 17. Random biopsies were performed 6 weeks after the
end of the first two cycles. Patients with persistent invasive
tumor underwent cystectomy; others received two additional cycles
of concurrent chemoradiotherapy. RESULTS: The mean follow-up was
36.3 months (range 3 to 72). Nine patients underwent early cystectomy
for nonresponse, and 2 patients underwent delayed cystectomy.
The overall rate of cystectomy was 25.6%. The rate of specific
survival at 3 and 5 years was 75% and 60%, respectively. The overall
rate of recurrence-free survival at 3 and 5 years was 63% and
33%, respectively. Two factors correlated with patient survival:
the presence of carcinoma in situ at first resection (P = 0.01)
and the response after the first two cycles (half dose; P = 0.004).
CONCLUSIONS: In our experience, concurrent chemoradiotherapy is
less effective than primary cystectomy for clinical Stage T2 bladder
cancer. This treatment may be unwarranted in patients with concomitant
carcinoma in situ at the first resection.

[Mitoxantrone chemoprophyaxis for multirecurrent
multifocal superficial bladder tumours: results of a phase 2 controlled

Twenty-three patients with multifocal superficial bladder cancer
(stage Ta - T1) unresponsive to at least 3 different intravesical
agents, were enrolled in a phase II study in order to evaluate
the prophylactic effects of intravesical Mitoxantrone (20 mg)
after complete endoscopic resection (TUR) of any papillary tumor.
The median follow-up was 6 months; 19 patients (82%) experienced
superficial tumor recurrence, 1 patient (4%) progression to muscle
invasion and 3 (13%) were disease-free, respectively. Six patients
(26%) experienced local side-effects. The progression rate is
acceptable; the side effects are at least similar to those available
in the literature, but in our experience, Mitoxantrone has no

Ligasure versus sutures in bladder replacement
with Montie ileal neobladder after radical cystectomy.
Manasia P, Alcaraz A, Alcover J.
Department of Urology, Hospital Clinic, University of Barcelona,
Barcelona, Spain. pmanasia8@iol.it
OBJECTIVES: Electrocoagulation became an indispensable tool
for surgeons. Ligasure is a computer-based, temperature-controlled
bipolar electrocoagulation system designed as an alternative to
suture ligatures, staplers, hemoclips and ultrasonic coagulators
for legating vessels and tissue bundles. Our aim was to analyse
the procedure time and intraoperative blood loss of the ileal
neobladder in a series of 30 highly selected patients. PATIENTS
AND METHODS: From March 1999 to May 2002, 30 patients (all men),
47 to 74 years old (mean age 57) with good performance status
(American Society of Anesthesiology score 1 and 2) underwent radical
cystectomy for bladder cancer and Montie ileal neobladder reconstruction,
using standard surgical technique, with the exception of 15 patients
that the Ligasure device was used for haemostasis. RESULTS: Procedure
time was significantly less in the Ligasure arm 170 minutes (range:
150 min - 200 min ) versus 220 minutes (range: 160 min - 250 min)
in the suture arm (p < 0.001). Blood loss was significantly
less in the Ligasure arm an average 849 cc (range: 820 cc - 900
cc) versus 968 cc (range: 1110 cc - 897 cc) in the suture arm
p < 0.02). There was no post-operative hemorrhage or return
to the operating room in either arm. Two patients, one in each
arm, received two units of blood for a slowly decreasing hematocrit
on postoperative day 3. There was no evidence of collateral tissue
injure and no injuries to the urinary or intestinal tract in either
arm. CONCLUSIONS: Ligasure is a safe and effective alternative
to sutures in cystectomy and bladder replacement, resulting in
decreased blood loss and significant time saving.

[Clinical significance of macroscopic 5-aminolevulinic
acid (ALA)-inducer fluorescence in transurethral resection of
non-invasive bladder cancer]
[Article in Russian]
Danil'chenko DI, Koenig F, Riedl K, Schnorr D, Waldman A, Al-Shukri
S, Loening SA.
Macroscopic fluorescence which is induced with aminolevulinic
acid (ALA) allows visualizing of small flat tumors, carcinoma
in situ, true neoplasm margins and dysplasias of the bladder.
Following ALA instillation, cystoscopy was performed under both
standard and blue light illumination. In a prospective randomized
multicenter study, 102 patients underwent TUR of bladder tumor(s)
either with white light or ALA-fluorescence. Significant reduction
in the number of residual tumours was detected in 59% (p = 0.005)
after 8 weeks, 3 months--in 58% (p = 0.002) and 6 months in 38%
(p = 0.01) respectively.

Radionuclide therapy with iodine-125 and other
auger-electron-emitting radionuclides: experimental models and
clinical applications.
Bodei L, Kassis AI, Adelstein SJ, Mariani G.
Nuclear Medicine Division, European Institute of Oncology, Milan,
Italy.
Auger-electron emitters represent an attractive alternative
to beta-particle emitters for cancer therapy if they can be placed
intracellularly, especially in close proximity to (or within)
nuclear DNA. Based on investigations in animal tumor models, including
those for ovarian cancer, bladder cancer, and brain and spinal
cord tumors, in which the thymidine analog 5-radioiodo-2'-deoxyuridine
(*IUdR) has been shown to be therapeutically efficacious, it is
hypothesized that iodine-125 and other Auger-electron-emitting
radionuclides might be valuable in the treatment of certain malignant
diseases, assuming that uptake of the radiopharmaceutical by tumor
cells exceeds that by normal dividing cells. Preliminary patient
studies have shown that this requirement can be met partially
by the locoregional administration of the radiopharmaceutical
and metabolic modulation of its uptake by tumor cells. Investigators
continue to seek molecules that can carry Auger-electron emitters
to nuclear DNA, especially those radionuclides with higher Auger-electron
yields and varying half-lives.

Radiotherapy for muscle-invasive urinary bladder
cancer in elderly patients.
Agranovich A, Czaykowski P, Hui D, Pickles T, Kwan W.
BC Cancer Agency, Fraser Valley Cancer Centre, Surrey, British
Columbia, Canada.
OBJECTIVE: To review retrospectively the outcome and toxicity
of Radiotherapy (RT) in the cohort of elderly patients (EP) with
muscle-invasive urinary bladder carcinoma (MIUBC). METHODS: Thirty-six
EP were treated with RT with radical intent. The age of the cohort
ranged from 71 to 89 years with a median of 79 years. Eighty percent
of the patients had Easter Cooperative Oncology Group (ECOG) 0
and 1 performance status. Conventional and accelerated fractionation
RT regimens were utilized. RESULTS: With median follow up of 45.8
months, the median survival was 23.9 months. There was a trend
toward better survival in patients treated with the accelerated
fractionation regimen. The median survival for that group (12)
has not yet been reached, where it is 9.7 months for the group
(24) treated with conventional fractionation. Treatment related
toxicity was low for any RT regimens. CONCLUSION: RT is well tolerated
by EP with good baseline performance status. The role of accelerated
fractionation should be tested by conducting randomized trials.

Chemotherapy and cystectomy for invasive transitional
cell carcinoma of bladder.
Raghavan D.

Center, Keck School of Medicine, University of Southern California,
Los Angeles, CA 90033, USA. draghava@usc.edu
Invasive transitional cell bladder cancer is associated with
occult metastasis. Approximately 50% of patients with clinically
localized, invasive bladder cancer ultimately die of their disease.
Systemic chemotherapy has been combined with radical cystectomy
in an attempt to improve survival. Phase I and II trials have
achieved tumor down-staging. Initial randomized trials did not
show a statistically significant survival benefit from systemic
single agent chemotherapy. More recently, two multi-center randomized
trials have shown a significant survival benefit from neoadjuvant
combination chemotherapy. Adjuvant chemotherapy trials, to date,
have failed to show statistically improved survival, although
most published studies have been methodologically flawed. For
invasive, clinically nonmetastatic bladder cancer, neo-adjuvant
chemotherapy followed by radical cystectomy is one of the new
standards of care. The role of postsurgical systemic chemotherapy
appears promising, but has not been proven in a randomized trial.
Molecular prognostication is now being incorporated into the design
of clinical trials of adjuvant chemotherapy for bladder cancer.

Recent advances in molecular and cell biology have led to a
greater understanding of the basic biology of bladder cancer.
However, despite these advances, surgery remains a key component
of modern bladder cancer treatment. Endoscopy is the mainstay
of the diagnosis and treatment of superficial bladder cancer.
Adjuvant intravesical therapy is recommended for patients with
high-risk superficial bladder cancer (Ta/T1 high grade). Select
patients with invasive bladder cancer (T2/T3) are candidates for
bladder-sparing approaches, incorporating transurethral resection
of bladder tumor (TURBT), radiation and chemotherapy. The results
and complications of endoscopic therapy are discussed. The role
of partial cystectomy, radical cystoprostatectomy, prostate-sparing
cystectomy, laparoscopic radical cystectomy, lymphadenectomy and
urethrectomy in invasive bladder cancer are discussed. The tumor
control outcomes and complications of radical cystoprostatectomy
(still the gold standard) for organ-confined and node-positive
bladder cancer are reported. Surgery remains an integral part
of the management of patients with bladder cancer. Improved understanding
of the biology of bladder cancer, combined with better surgical
techniques and safety, continues to improve the survival and quality
of life of patients with bladder cancer.

BACKGROUND: The objectives of the current study were to evaluate
the safety and efficacy of gemcitabine plus docetaxel in patients
with unresectable (Stage T4 or >/= N1) metastatic or locally
advanced transitional cell carcinoma (TCC) of the urothelial tract.
METHODS: A total of 27 patients were enrolled in the current multisite
study, which was performed within the University of California-Los
Angeles Community Oncology Research Network. The first 10 patients
in the study received 800 mg/m(2) of gemcitabine intravenously
on Days 1, 8, and 15 of a 28-day treatment cycle. In addition,
on Day 1, the first 10 patients received 80 mg/m(2) of docetaxel
intravenously after completion of the gemcitabine infusion. Because
of dose-limiting toxicity (neutropenia), the initial dose of docetaxel
was reduced to 60 mg/m(2) for the remaining patients who entered
the study (n = 17 patients). RESULTS: Neutropenia was the most
common adverse event that occurred in patients at the Grade 3
level (in 10 of 27 patients; 37.0%) and the Grade 4 level (in
6 of 27 patients; 22.2%). There were no other adverse events at
the Grade 4 toxicity level. Twenty-five of 27 patients (92.6%)
completed more than 1 cycle of combination therapy and were evaluated
for antitumor responses. The frequency of objective clinical responses
was 33.3% (9 of 27 patients). Complete responses to therapy were
observed in 2 of 27 patients (7.4%), and partial responses were
observed in 7 of 27 patients (25.9%). The median duration of response
was 20 weeks (range, 12+ weeks to 152 weeks). The median survival
duration was 52 weeks (range, 12 weeks to 160+ weeks). Four of
27 patients (14.8%) remained alive at the time of the current
data analysis. CONCLUSIONS: The results of the current study suggested
that combination therapy with gemcitabine and docetaxel was an
effective treatment for patients with unresectable (Stage T4 or
>/= N1) metastatic or locally advanced TCC of the urothelial
tract. Gemcitabine plus docetaxel appeared to be tolerated well,
and treatment-related toxicities were limited to hematologic toxicities.
Because cisplatin-containing regimens are contraindicated for
patients with impaired renal function, the gemcitabine plus docetaxel
combination may prove to be an effective and well tolerated treatment
option for these patients. Copyright 2003 American Cancer Society.

Laparoscopic approaches to urologic malignancies.
Matin SF.
Department of Urology, The University of Texas MD Anderson Cancer
Center, 1515 Holcombe Boulevard, Unit 446, Houston, TX 77030,
USA. surmatin@mdanderson.org
Urologic laparoscopy has had its greatest impact on patients
with genitourinary malignancies. Only pelvic lymph node dissection
and the occasional nephrectomy were considered oncologically feasible
early in the evolution of laparoscopic urology. Presently, multiple
approaches are considered standard at centers of excellence and
in the general community. Laparoscopic adrenalectomy and radical
nephrectomy have gained overwhelming acceptance. Laparoscopic
cytoreductive nephrectomy has been found to be feasible for select
patients with metastatic renal cell carcinoma. Minimally invasive
nephron-sparing approaches, such as cryoablation, radiofrequency
ablation, and laparoscopic partial nephrectomy, continue to generate
great interest, but follow-up remains limited. Early data with
laparoscopic radical prostatectomy suggest excellent continence
rates and equivalent oncologic results based on pathologic surrogates
of cure. However, long-term data are still needed, in addition
to validated information regarding return of erectile function
and quality of life. Other novel therapies, such as laparoscopic
radical cystectomy with urinary diversion and laparoscopic retroperitoneal
lymph node dissection, hold great promise of benefiting patients
with urologic malignancies.

Delaying radical cystectomy for muscle invasive
bladder cancer results in worse pathological stage.
Chang SS, Hassan JM, Cookson MS, Wells N, Smith JA Jr.
Department of Urologic Surgery, Vanderbilt University Medical
Center, Nashville, Tennessee 37232-2765, USA. sam.chang@vanderbilt.edu
PURPOSE: While radical cystectomy remains the treatment of
choice for invasive transitional cell carcinoma, the importance
of its timing has been increasingly scrutinized. We determined
whether the interval between diagnosis of muscle invasion and
definitive radical cystectomy influenced pathological staging
outcome. MATERIALS AND METHODS: Of the 303 patients who underwent
radical cystectomy from January 1998 to December 2001, 153 were
diagnosed with muscle invasive transitional cell carcinoma at
transurethral resection. Charts were reviewed for pathological
stage, demographics and time between diagnosis of muscle invasion
and radical cystectomy. RESULTS: Mean patient age was 67.2 years
(range 35 to 88) with the majority (121 of 153, 79%) being male.
At the time of cystectomy, 68 of 153 (44%) patients had organ
confined disease (pT2B or lower), while node positive disease
was found in 58 of 153 patients (38%). Mean time from transurethral
resection diagnosis of muscle invasive disease until cystectomy
was 63 days (range 8 to 473). A statistically significant correlation
existed between time of diagnosis and cystectomy, and final pathological
stage. Specifically, those patients with an interval greater than
90 days were more likely to have pT3 or higher, nonorgan confined
disease compared to those patients undergoing cystectomy before
90 days (81% versus 52%, p = 0.01). Furthermore, those patients
with organ confined disease had a significantly shorter mean time
between diagnosis and cystectomy of 47.5 days versus 75.1 days
for nonorgan confined disease (t test p = 0.02). CONCLUSIONS:
In patients with muscle invasion at diagnosis, a delay in surgery
is associated with more advanced pathological stage, especially
when the delay is longer than 90 days. While appropriate time
should be given for consideration of options and pretreatment
evaluation, undue delay may compromise cancer control.

Hospital, London, United Kingdom.
INTRODUCTION: The effect of pelvic radiotherapy on anorectal
function is not clearly documented and is investigated in this
prospective study. METHODS: Thirty-one males (median age, 70 years)
with carcinoma of the prostate (n = 28) and bladder (n = 3) completed
proctitis/incontinence symptom score questionnaires and anorectal
physiology studies before and six weeks after pelvic radiotherapy.
At six months after completion of radiotherapy, 25 of these patients
were studied again. The results were expressed as medians and
ranges and compared by the Mann-Whitney U test (2-tailed). RESULTS:
Six weeks and six months after treatment, respectively, the proctitis
symptom scores (0 (0-4) vs. 2 (0-7) (P < 0.001) vs. 2 (0-5)
(P < 0.001)) and the incontinence symptom scores (0 (0-5) vs.
4 (0-11) (P < 0.001) vs. 3 (0-14) (P < 0.001)) increased.
Urgency, frequency of defecation, anorectal pain, incontinence
to liquid stool and to flatus, and alteration in lifestyle were
significant symptoms after treatment. The following measurements
decreased: anal canal resting pressure (83 (35-137) vs. 79 (26-152)
(P = NS) vs. 71 (29-97) (P < 0.01) cm H2O), the squeeze increment
(152 (51-135) vs. 162 (63-321) (P = NS) vs. 108 (45-296) (P <
0.042) cm H2O), and the maximum tolerated rectal volume (245 (115-450)
vs. 194 (112-344) (P < 0.05) vs. 200 (109-350) (P < 0.138)
ml). The rectal electrosensory threshold increased (20 (5.4-44)
vs. 22 (9-50.5) (P < 0.134) vs. 31.5 (13.6-76) (P < 0.001)
mA). CONCLUSIONS: Anorectal symptoms at six weeks after pelvic
radiotherapy are related to reduced rectal capacity and compounded
at six months by diminished internal and external sphincter function
and rectal mucosal sensitivity.

Immune mechanisms in bacillus Calmette-Guerin
immunotherapy for superficial bladder cancer.
Bohle A, Brandau S.
Department of Urology, HELIOS Agnes Karll Hospital, Am Hochkamp
21, 23611 Bad Schwartau, Germany. aboehle@badschwartau.helios-kliniken.de
PURPOSE: Of all medical disciplines it is exclusively in urology
in which immunotherapy for cancer has an established position
today with intravesical bacillus Calmette-Guerin (BCG) against
superficial bladder carcinoma recurrences. BCG is regarded as
the most successful immunotherapy to date. However, the mode of
action has not yet been fully elucidated. We provide a thorough
overview of this complex field of research. MATERIALS AND METHODS:
Rather than simply reporting all experimental data available for
better understanding the involved immune mechanisms, we chose
to provide comprehensively only information supported by several
independent pathways of evidence. RESULTS: Major findings made
during the last few years include systematic analyses of patient
material, detailed in vitro studies and investigations in animal
models, which have led to a substantially greater understanding
of the mechanisms involved. CONCLUSIONS: The efficacy of BCG is
based on a complex and long lasting local immune activation. The
bladder as a confined compartment, in which high local concentrations
of the immunotherapy agent and effective recruitment of immune
cells can be achieved, serves as an ideal target organ for this
type of immunotherapy approach.

34 patients with advanced unresectable or metastatic urothelial
carcinoma who had not received prior chemotherapy for metastatic
disease were treated with pegylated-liposomal doxorubicin (PLD)
50 mg/m(2) by a 1-h intravenous infusion (i.v.) every 4 weeks
in a multi-institutional phase II trial. 6 of 30 evaluable patients
had a partial response to treatment (20%; 95% Confidence Interval
(CI), 8-39%) and seven patients had stable disease. Toxicities
were primarily non-haematological, but severe palmar-plantar erythrodysesthesia
(PPE), lethargy and anorexia were infrequent. Despite a high proportion
of patients with poor prognostic features, PLD had clinically
significant activity in urothelial cancer in this study. The activity
and unique toxicity profile of this drug make it of interest for
further study in advanced urothelial cancers in combination with
other active agents.

Effect of routine repeat transurethral resection
for superficial bladder cancer: a long-term
observational study.
Grimm MO, Steinhoff C, Simon X, Spiegelhalder P, Ackermann
R, Vogeli TA.
Department of Urology, Heinrich-Heine University, Dusseldorf,
Germany.
PURPOSE: We determined the long-term outcome in patients with
superficial bladder cancer (Ta and T1) undergoing routine second
transurethral bladder tumor resection (ReTURB) in regard to recurrence
and progression. MATERIALS AND METHODS: We performed an inception
cohort study of 124 consecutive patients with superficial bladder
cancer undergoing transurethral resection and routine ReTURB (83)
between November 1993 and October 1995 at a German university
hospital. Immediately after transurethral resection all lesions
were documented on a designed bladder map. ReTURB of the scar
from initial resection and other suspicious lesions was performed
at a mean of 7 weeks. Patients were followed until recurrence
or death, or a minimum of 5 years. RESULTS: Residual tumor was
found in 33% of all ReTURB cases, including 27% of Ta and 53%
of T1 disease, and in 81% at the initial resection site. Five
of the 83 patients underwent radical cystectomy due to ReTURB
findings. The estimated risk of recurrence after years 1 to 3
was 18%, 29% and 32%, respectively. After 5 years 63% of the patients
undergoing ReTURB were still disease-free (mean recurrence-free
survival 62 months, median 87). Progression to muscle invasive
disease was observed in only 2 patients (3%) after a mean observation
of 61 months. CONCLUSIONS: These data suggest a favorable outcome
regarding recurrence and progression in patients with superficial
bladder cancer who undergo ReTURB. ReTURB is suggested at least
in those at high risk when bladder preservation is intended.

The systemic treatment of advanced and metastatic
bladder cancer.
Hussain SA, James ND.

Birmingham, Birmingham, UK. hussainsa@cancer.bham.ac.uk <hussainsa@cancer.bham.ac.uk>
Bladder cancer is the second most common genitourinary tumour
and is a significant cause of morbidity and mortality. Trials
of neoadjuvant and adjuvant chemotherapy have failed to show a
survival advantage, although these studies generally had suboptimum
design and an insufficient number of patients. Despite the introduction
of newer agents, the median survival for metastatic disease is
about 1 year; however, improvements in quality of life have been
achieved. Platinum drugs should be included in studies of combination
chemotherapy regimens wherever possible. There have been various
studies exploring the role of taxanes, gemcitabine, ifosfamide,
and platinum in double and triple combinations in different schedules
to maximise dose intensity and improve effectiveness but large
phase III trials are needed. The current tumour, node, and metastasis
staging system is insufficient to predict outcome in patients
with bladder cancer irrespective of the treatment they received.
Evaluation of molecular prognostic markers should be incorporated
into phase II and III trials to define their roles in clinical
outcome. Future studies should stratify patients according to
the number of risk factors they have to avoid imbalance in treatment
groups and patients should be carefully selected.

Neoadjuvant chemotherapy plus cystectomy compared
with cystectomy alone for locally advanced bladder cancer.

D, Crawford ED.
M.D. Anderson Cancer Center, Houston, USA.
BACKGROUND: Despite aggressive local therapy, patients with
locally advanced bladder cancer are at significant risk for metastases.
We evaluated the ability of neoadjuvant chemotherapy to improve
the outcome in patients with locally advanced bladder cancer who
were treated with radical cystectomy. METHODS: Patients were enrolled
if they had muscle-invasive bladder cancer (stage T2 to T4a) and
were to be treated with radical cystectomy. They were stratified
according to age (less than 65 years vs. 65 years or older) and
stage (superficial muscle invasion vs. more extensive disease)
and were randomly assigned to radical cystectomy alone or three
cycles of methotrexate, vinblastine, doxorubicin, and cisplatin
followed by radical cystectomy. RESULTS: We enrolled 317 patients
over an 11-year period, 10 of whom were found to be ineligible;
thus, 154 were assigned to receive surgery alone and 153 to receive
combination therapy. According to an intention-to-treat analysis,
the median survival among patients assigned to surgery alone was
46 months, as compared with 77 months among patients assigned
to combination therapy (P=0.06 by a two-sided stratified log-rank
test). In both groups, improved survival was associated with the
absence of residual cancer in the cystectomy specimen. Significantly
more patients in the combination-therapy group had no residual
disease than patients in the cystectomy group (38 percent vs.
15 percent, P<0.001). CONCLUSIONS: As compared with radical
cystectomy alone, the use of neoadjuvant methotrexate, vinblastine,
doxorubicin, and cisplatin followed by radical cystectomy increases
the likelihood of eliminating residual cancer in the cystectomy
specimen and is associated with improved survival among patients
with locally advanced bladder cancer. Copyright 2003 Massachusetts

Concurrent cisplatin, 5-fluorouracil, leucovorin,
and radiotherapy for invasive bladder cancer.
Chen WC, Liaw CC, Chuang CK, Chen MF, Chen CS, Lin PY,
Chang PL, Chu SH, Wu CT, Hong JH.
Department of Radiation Oncology, Chang Gung Memorial Hospital,
Chiayi, Taiwan.
PURPOSE: To investigate the tolerance and efficacy of a modified
concurrent chemoradiation (CCRT) protocol for patients with invasive
bladder cancer "unfit" for radical cystectomy. METHODS
AND MATERIALS: Twenty-three muscle-invasive bladder cancer patients
who were unfit for or unwilling to receive radical cystectomy
were enrolled in this study. All patients had transitional cell
carcinoma of bladder, and distribution of stage was 14 (61%),
1 (4%), and 8 (35%) for T3a, T3b, and T4, respectively. This study
included a relatively old-age population, with the median age
being 75 and 70% of patients over 70 years old. Patients were
treated with maximal transurethral resection of the bladder tumor
followed by curative CCRT. The chemotherapy (C/T) regimen was
comprised of cisplatin, 50 mg/m(2) intravenously (i.v.) on Day
1; 5-fluorouracil (5-FU), 500 mg/m(2)/day by continuous i.v. infusion
on Days 1-3; and leucovorin, 50 mg/day by continuous i.v. infusion
on Days 1-3. Chemotherapy course was repeated at 21-day intervals.
The radiation dose was 44-45 Gy to whole pelvis and 60-61.2 Gy
to bladder, with a daily fraction of 1.8-2 Gy. The completeness
of the CCRT protocol was defined as patients receiving at least
55 Gy of radiotherapy to the whole bladder and at least three
courses C/T. RESULTS: Seventy-four percent of patients (17/23)
completed the CCRT protocol. Radiation Therapy Oncology Group
(RTOG) Grade 3 acute toxicities were observed in 4 patients, which
included leucopenia, vomiting, genitourinary (GU) tract infection,
and diarrhea. No treatment-related deaths occurred during the
CCRT period. RTOG Grade 3 or more late complications were observed
in 3 patients; one of them died of radiation cystitis superimposed
with GU infection. Of the 18 patients whose response to CCRT was
evaluated, a complete tumor response was documented in 16 patients
(89%). With a median follow-up of 3 years, the 3-year overall
survival (OS) and disease-free survival (DFS) for all patients
was 69% and 65% respectively. Meanwhile, the 3-year overall and
DFS rates for patients who completed CCRT vs. those who did not
complete CCRT were 82% vs. 33% and 75% vs. 33%, respectively (p
= 0.18 for OS and p = 0.04 for DFS). CONCLUSIONS: Concurrent cisplatin,
5-FU, leucovorin, and radiotherapy for treatment of invasive bladder
cancer is a feasible and promising treatment even for relatively
old patients. Our results are comparable to those in recent studies
by using combined modality treatment or neoadjuvant chemotherapy
plus radical cystectomy. Consequently, this novel protocol warrants
a prospective clinical trial and may be a safe, effective alternative
to radical cystectomy.

[Combined therapy for patients with invasive bladder
cancer]
[Article in Russian]
Startsev VIu, Karelin MI.
Central Research Institute of Roentgeno-Radiology, St. Petersburg.
Organ preservation has been investigated inmuscle-invasivebladder
cancer over the past years as an alternative to standard radical
cystectomy. However, the morbidity of radical cystectomy and early
reports of good results of radical transuretheral resection of
bladder tumors (TURBT) have stimulated interest in combined treatment
for muscle-invasive bladder cancer. Organ preservation requires
a trimodal schedule, including transuretheral surgery, mega voltage
radical external beam radiotherapy (EBRT) and adjuvant chemotherapy
(ACT). Our results point to the effectiveness of combined therapy
of urinary bladder in old patients with invasive, advanced cancer
(stage T2). These results demonstrate the effectness of intra-arterial
ACT when used in combination with EBRT.

Muscle-invasive bladder cancer is typically an aggressive solid
tumour with the propensity for early systemic dissemination. Although
curative-intent local therapy with either radical cystectomy or
radiotherapy remains the gold standard intervention, the high
rate of systemic failure has prompted investigators to evaluate
various strategies in an attempt to improve survival, including
the early administration of systemic chemotherapy. Recently completed,
Phase III studies of neoadjuvant chemotherapy trials demonstrated
a modest, but real survival advantage for a small subset of patients.
Other strategies include, attempts to both preserve the bladder
using combinations of limited surgical resection, systemic chemotherapy
and radiotherapy. This review focuses on the potential of neoadjuvantly-administered
therapies to impact the management of muscle invasive bladder
cancer.

[Clinical study of chemoradiotherapy using low
dose cisplatinum as X-ray intensifier in patients with urothelial
carcinoma]
[Article in Japanese]

Chemoradiotherapy using cisplatinum (CDDP) as the X-ray intensifier
was performed on patients with urothelial carcinoma. Ten lesions
in 9 patients, 6 patients with postoperative relapse and 3 who
received the therapy as a palliative treatment for progressive
carcinoma, were evaluated. Four of the patients with postoperative
relapse had undergone adjuvant chemotherapy. On the day of the
treatment, the 9 patients were given continuous intravenous infusion
of CDDP at the dose level of 5-12 mg/day prior to external irradiation
at 50-66 Gy. The response to the therapy was categorized as complete
response in 5 patients, partial response in 4, and no change in
1. The response rate was 90%, indicating achievement of a good
local control. Pain relief and improvement of hydronephrosis were
also observed in patients who underwent the therapy for treatment
of progressive carcinoma. All adverse reactions were mild in intensity.
These results suggest that the chemoradiotherapy is useful for
both patient groups, those who have a postoperative relapse and
those who undergo the therapy as a palliative treatment for progressive
carcinoma.

Neoadjuvant chemotherapy in invasive bladder cancer:
a systematic review and meta-analysis.
Advanced Bladder Cancer Meta-analysis Collaboration.
BACKGROUND: Controversy exists as to whether neoadjuvant chemotherapy
improves survival in patients with invasive bladder cancer, despite
randomised controlled trials of more than 3000 patients. We undertook
a systematic review and meta-analysis to assess the effect of
such treatment on survival in patients with this disease. METHODS:
We analysed updated data for 2688 individual patients from ten
available randomised trials. FINDINGS: Platinum-based combination
chemotherapy showed a significant benefit to overall survival
(combined hazard ratio [HR] 0.87 [95% CI 0.78-0.98, p=0.016];
13% reduction in risk of death; 5% absolute benefit at 5 years
[1-7]; overall survival increased from 45% to 50%). This effect
was observed irrespective of the type of local treatment, and
did not vary between subgroups of patients. The HR for all trials,
including those using single-agent cisplatin, tended to favour
neoadjuvant chemotherapy (HR=0.91, 95% CI 0.83-1.01) although
this tendency was not significant (p=0.084). Although platinum
based combination chemotherapy was beneficial, there was no evidence
to support the use of single-agent platinum; indeed, there was
a significant difference in the effect between these groups of
trials (p=0.044). INTERPRETATION: This improvement in survival
encourages the use of platinum-based combination chemotherapy
for patients with invasive bladder cancer.

Is there a therapeutic role for post-chemotherapy
retroperitoneal lymph node dissection in metastatic transitional
cell carcinoma of the bladder?

CA, Grossman HB, Dinney CP, Swanson DA, Pisters LL.

Center, Houston, Texas 77030, USA.
PURPOSE: We identified a subset of patients with bladder cancer
(transitional cell carcinoma) and regional nodal metastasis to
the retroperitoneal lymph nodes without detectable systemic dissemination.
While the majority of these patients respond initially to chemotherapy,
most have disease relapse at the same site within a year. We report
the results of a phase II study exploring the potential benefit
of retroperitoneal lymph node dissection in patients with transitional
cell carcinoma of the bladder in whom disease has shown a significant
response to chemotherapy. MATERIALS AND METHODS: A total of 11
patients with biopsy proven metastatic transitional cell carcinoma
in the retroperitoneal lymph nodes and no evidence of visceral
metastatic disease in whom disease showed a significant response
to chemotherapy underwent complete bilateral retroperitoneal lymph
node dissection. The end point of study was disease specific survival,
calculated from the time of retroperitoneal lymph node dissection
to death from transitional cell carcinoma of the bladder. RESULTS:
Four patients underwent delayed retroperitoneal lymph node dissection.
Seven patients underwent concurrent cystectomy, and pelvic and
retroperitoneal lymph node dissection. There was no perioperative
mortality. Nine patients had evidence of residual disease in the
retroperitoneal nodes. Seven patients have recurrence outside
of the original surgical field with a median time to recurrence
of 7 months and 6 died at a median time to death of 8 months (range
5 to 14). One patient with retrocrural recurrence attained a complete
response to salvage chemotherapy and remained disease-free 57
months after retroperitoneal lymph node dissection. For all 11
patients median disease specific and recurrence-free survival
rates were 14 and 7 months, respectively. Four-year disease specific
and recurrence-free survival rates were 36% and 27%, respectively.
We stratified the patients based on the number of involved lymph
nodes at retroperitoneal lymph node dissection and noted that
viable tumor in no more than 2 lymph nodes correlated with greater
disease specific and recurrence-free survival (p = 0.006 and 0.01,
respectively). CONCLUSIONS: Retroperitoneal lymph node dissection
can be safely performed for metastatic transitional cell carcinoma.
Retroperitoneal lymph node dissection has curative potential,
particularly in patients with viable tumor in no more than 2 lymph
nodes after chemotherapy.

OBJECTIVE: The aim of this study is to know if the use of oral
Tegafur associated to intravesical mitomycin is effective in the
prevention of the relapses of Ta bladder tumors. METHOD: This
is a prospective study in which we compare the recurrence rate
and the disease-free interval of 2 groups of 40 patients each
one, the first of them treated after the TUR with oral Tegafur
and intravesical mitomycin, and the second with intravesical mitomycin
alone. Tolerance of Tegafur was also studied. RESULTS: The group
of the Tegafur presented a descent of the relapse rate and a continuation
of the time free of illness; but it was not statistically significant.
The tolerance to the drug was good, without important adverse
effects. CONCLUSIONS: Tegafur seems an useful drug in the prevention
of the recurrence of superficial bladder tumors, although it will
be necessary bigger studies to reach statistically valid conclusions.

Intravesical bacillus Calmette-Guerin versus mitomycin
C for Ta and T1 bladder cancer.
Shelley MD, Court JB, Kynaston H, Wilt TJ, Coles B, Mason M.
Research Laboratories, Velindre NHS Trust, Velindre Road, Whitchurch,

BACKGROUND: Tumour recurrence following transurethral resection
(TUR) for Ta and T1 bladder cancer is a major clinical problem.
Intravesical administration of mitomycin C (MMC) or bacillus Calmette-Guerin
(BCG) has proven prophylactic activity but both are associated
with local and systemic side-effects. A systematic review was
carried out to compare the efficacy of these two agents. OBJECTIVES:
To undertake a systematic review and meta-analysis comparing intravesical
mitomycin C and Bacillus Calmette-Guerin in terms of tumour recurrence,
disease progression and overall survival in Ta and T1 bladder
cancer. Treatment-related toxicities would also be evaluated.
SEARCH STRATEGY: A comprehensive search of MEDLINE, EMBASE, Healthstar,
Cochrane Controlled Trials Register, Cancerlit, and DARE was performed,
and hand searching of relevant journals undertaken. SELECTION
CRITERIA: Trials in any language were included in the meta-analysis
if they were properly randomised, included medium to high risk
patients with Ta or T1 bladder cancer and compared intravesical
MMC versus BCG. DATA COLLECTION AND ANALYSIS: Trial eligibility,
methodological quality and data extraction were assessed independently
by two reviewers. Time to event analysis was evaluated using log
hazard ratios, with a sensitivity analysis for subgroups according
to patient's risk of recurrence. MAIN RESULTS: Twenty-five articles
were identified but only seven were considered eligible. This
represented 1901 evaluable patients in total, 820 randomised to
MMC and 1081 to BCG. Six trials had sufficient data for meta-analysis
and included 1527 patients, 693 in the mitomycin arm and 834 in
the BCG arm. The weighted mean log hazard ratio (variance) for
tumour recurrence for the six trials was - 0.022 (0.005). This
indicated no significant difference between MMC and BCG (p = 0.76).
However, the meta-analysis indicated evidence of significant heterogeneity
between trials (p = 0.001). A subgroup analysis of three trials
that included only high risk Ta and T1 patients indicated no heterogeneity
(p = 0.25) and a log hazard ratio (variance) for recurrence of
-0.371 ( 0.012). With MMC used as the control in the meta-analysis,
a negative ratio is in favour of BCG and, in this case, is highly
significant (p = 0.0008). The seventh trial, in abstract form
only, used BCG in low doses for two arms of the trial (27 mg and
13.5mg) compared to a standard dose of mitomycin C (30mg), and
reported a significantly reduced recurrent rate with BCG (27mg)
compared to mitomycin C (p = 0.001). Only two trials included
sufficient data to analyse disease progression and survival, representing
a total of 681 patients; 338 randomised to BCG and 343 to MMC.
There was no significant difference between MMC and BCG for disease
progression (log hazard ratio + variance: 0.044 + 0.04, p = 0.16)
or survival (-0.112 + 0.03, p = 0.50). Local toxicities (dysuria,
cystitis, frequency, and haematuria) were associated with both
MMC (30%) and BCG (44%). Systemic toxicities, such as chills,
fever and malaise, were observed with both MMC and BCG (12% and
19%, respectively) although skin rash was more common with MMC.
REVIEWER'S CONCLUSIONS: The data from the present meta-analysis
indicate that tumour recurrence was significantly reduced with
intravesical BCG compared to MMC only in the subgroup of patients
at high risk of tumour recurrence. However, there was no difference
in terms of disease progression or survival, and the decision
to use either agent might be based on adverse events and cost.

Bladder cancer.
Borden LS Jr, Clark PE, Hall MC.
Department of Urology, Wake Forest University School of Medicine,
Medical Center Boulevard, Winston-Salem, NC 27157, USA.
Bladder cancer is a significant public health problem responsible
for more than 130,000 deaths annually worldwide. Disease prevalence
is also remarkable, with more than 500,000 patients carrying the
diagnosis in the United States alone. Significant progress has
been made in understanding the underlying molecular and genetic
events in bladder cancer. However, there remains a great need
for the development of reliable markers that can provide clinically
useful information regarding diagnosis and prognosis and to facilitate
the selection of appropriate therapy in the individual patient.
Ongoing and future investigation is anticipated to refine treatment
of patients with high-risk superficial disease, to determine the
role of neoadjuvant and adjuvant chemotherapy for high-risk invasive
disease, and to improve the efficacy of chemotherapy for patients
with metastatic bladder cancer.

Gallium nitrate in the treatment of bladder cancer.
Einhorn L.
Department of Medicine, Indiana University, Indianapolis, IN 46202,
USA.
For over 15 years, the MVAC regimen (methotrexate/vinblastine/doxorubicin/cisplatin)
has been standard chemotherapy for patients with unresectable
or metastatic bladder cancer. The taxanes and gemcitabine have
provided new treatment options, but development of more effective
regimens is needed. Gallium nitrate has significant activity as
a single agent in the treatment of advanced bladder cancer, including
activity in heavily pretreated patients and patients previously
treated with MVAC or single-agent cisplatin. At a dosage of 300
mg/m(2) daily by continuous infusion for 5 to 7 days every 3 weeks,
toxicity has been acceptable in the treatment of patients with
refractory disease. Gallium nitrate is also active in combination
regimens for advanced bladder cancer. Because it has a different
mechanism of action, minimal myelosuppression, and activity in
previously treated patients, gallium nitrate may be useful as
a single agent in patients with advanced bladder cancer who fail
front-line chemotherapy regimens. Evaluation of gallium nitrate
in combination with newer agents such as the taxanes or gemcitabine
may also be warranted given its activity, different mechanism
of action, and non-overlapping toxicity profile. Copyright 2003

[Mucinous adenocarcinoma of the bladder]
[Article in Spanish]
Palmero Marti JL, Queipo Zaragoza JA, Bonillo Garcia MA, Budia
Alba A, Vera Sempere FJ, Jimenez Cruz JF.
Servicio de Urologia, Hospital Universitario La Fe, Valencia.
Mucinous adenocarcinoma is a rare entity within the group of
primary adenocarcinoma of the bladder which represent 0.5-2% of
all malignant epithelial bladder tumours. In spite of the rarity
of this tumoral type; it is a poor prognosis entity mainly due
to its diagnosis especially in advanced stage of the disease.
There is no general agreement on the treatment of adenocarcinoma
of bladder. Not withstanding surgery would be the only curative
treatment, although unfortunately, it is curative in just a few
cases. We report six cases with mucinous adenocarcinoma of the
bladder attended in our Department in the last ten years (january
1991-december 2001). In one of them a radical cystectomy was performed,
while transurethral resection with or without adjuvant treatment
was practiced in the other one. Only one patient is alive today,
namely, the one where the tumour not invade the muscular tissue.
These findings show the discouraging results of this entity closely
intertwined with the pathologic stage.

BACKGROUND: Despite the fact that new drugs have emerged from
clinical research in urothelial cancer during the last decade,
the prognosis of patients with advanced disease remains poor with
a median survival of 12 to 14 months. We designed a feasibility
study of gemcitabine and oxaliplatin (GO) in patients with advanced
urothelial cancer. PATIENTS AND METHODS: Twenty patients received
bimonthly cycles of gemcitabine 1500 mg/m2 and oxaliplatin 85
mg/m2. The cycles were given at 2-week intervals without G-CSF
support. Thirteen patients were treated with the GO combination
as first-line chemotherapy because of a poor performance status
or a creatinine clearance < 1 ml/s. RESULTS: The median number
of cycles of GO was 5 (1-7). The median number of days between
cycles was 14 throughout the treatment. Seven (8%) out of 87 cycles
had to be delayed because of neutropenia or asthenia. A 25% dose
reduction in the doses of cytotoxic drugs was necessary in 2 patients.
Chemotherapy was stopped before the sixth cycle because of an
early death related to a myocardial infarction in 1 patient, a
grade 3 neuropathy in 1 patient and a progressive disease in 9
patients. CONCLUSION: Using these doses and schedules, the GO
regimen appears a safe therapy for patients with advanced urothelial
cancer. Phase II studies are required to assess the possible role
of this combination in advanced urothelial cancer.

BACKGROUND & OBJECTIVE: Superficial bladder transitional
cell carcinoma is aggressive and tends to recurrence after operation.
In order to prevent the relapse of bladder neoplasms,this study
was designed to explore the effect of intravesical instillation
of pirarubicin (THP) together with polyvinylpyrrolidone (PVP)
on patients with superficial bladder cancer who had undergone
surgical operation. METHODS: A total of 34 cases were enrolled
from October 1999 to May 2002. After one week of operation, pirarubicin
(20 mg) dissolved in 10 ml normal saline plus 20 ml PVP was instilled
into bladder, and was retained for 60 minutes. In the following
7 weeks, intravesical instillation of pirarubicin was administered
once a week. Subsequently it was done bi-monthly, finally once
a month for 6 months. RESULTS: Follow-up was performed for 5-26
months (mean:17.2 months). Among the 34 cases, recurrence was
found in 2 cases (5.8%),bladder irritation in 6 cases (17.6%)
and hematuria in 4 cases (11.7%) as well. CONCLUSION: Intravesical
instillation of THP/PVP is effective for prevention of postoperative
recurrence of superficial bladder cancer with fewer side effects.
Further study is needed for wide use in such way.

AIM: To evaluate the effect of intravesical instillation of
Bacillus Calmette-Guerin (BCG) in the prevention of recurrence
and progression of the superficial bladder cancer. METHODS: Between
February 1989 and May 1994, 170 patients with histologically proven
superficial transitional cell carcinoma of the bladder stage Ta
and T1 were assessed as eligible for 6-week + 6-month protocol
of intravesical BCG instillation at the Split University Hospital.
All patients underwent complete transurethral resection of the
tumor, which established tumor size, histology, stage, and absence
of muscle invasion. Out of 170 patients offered to receive intravesical
BCG instillations, 80 agreed to undergo the treatment (BCG group),
and 90 refused it (control group). The median duration of follow-up
was 64 months (range, 16-128). RESULTS: The BCG group had lower
incidence rates of recurrence (12 vs 26 events per 100 patient-years
in controls, p<0.001) and progression (3.0 vs 6.6 events per
100 patient-years in controls, p=0.017, large-sample one-sample
binomial test in both cases) than the control group, but similar
mean intervals to first recurrence or progression. The 5-year
recurrence-free rates were 55% in BCG patients and 31% in controls,
and in case of progression, 86% and 70%, respectively. Cox regression
showed that the independent predictors of recurrence were tumor
size (p<0.001), absence of BCG treatment (p=0.002), and patient
age (p=0.05). The single independent predictor of tumor progression
was absence of BCG treatment, but only in case of tumor grade
III (roughly doubling the relative risk of the event). CONCLUSION:
Our data suggest that BCG intravesical instillation, using 6 week
+ 6 month scheme, prevents against recurrence and progression
of superficial bladder tumors. This treatment should be especially
advocated in patients with advanced grade tumors, but the scheme
remains to be evaluated against other BCG treatment schemes.

In the United States, radical cystectomy is viewed as the gold
standard and, with few exceptions, is the only treatment recommended
for patients with invasive bladder cancer. In many areas of cancer
treatment, however, the trend in the 1990s has been toward organ
conservation using combined chemotherapy and radiation with or
without conservative local surgery. For patients with breast,
esophageal, anal, and laryngeal cancers as well as limb sarcomas,
conservative therapy often is recommended. However, invasive bladder
cancer has not been viewed generally as a condition that allows
for conservative management. In the past 15 years, the Radiation
Therapy Oncology Group (RTOG) has completed six prospective protocols
of combined-modality therapy for patients with muscle-invasive
cancer who were candidates for cystectomy. Bladder preservation
with intravesical surgery, chemotherapy, and radiation therapy
were combined as initial treatment, with radical cystectomy recommended
for incomplete responders. Five of the RTOG protocols were Phase
I-II trials of concurrent chemotherapy and radiation therapy,
and one protocol was a Phase III trial that tested the efficacy
of adjuvant chemotherapy with methotrexate, cisplatin, and vinblastine.
A total of 415 patients were entered on these trials. The 5-year
overall survival rate was approximately 50%, with three-quarters
of those patients achieving a cure for their bladder cancer while
maintaining a functioning bladder. The current RTOG protocol and
its successor are directed toward better tolerated and potentially
more effective chemotherapy regimens that may result in a high
protocol compliance rate and, possibly, a higher overall survival
rate. The trimodality therapeutic approach used in all of these
RTOG protocols was more effective compared with the radiation
monotherapy offered in the 1970s and with protocols that used
only chemotherapy. Trimodality therapy with selective bladder
preservation is not designed to take the place of radical cystectomy;
however, it may be offered as a reasonable alternative to patients
with invasive bladder cancer who are not willing to undergo radical
cystectomy and urinary diversion. A bladder-sparing strategy may
be offered appropriately to highly selected patients with the
understanding that radical cystectomy is an available option in
those who fail combined radiation and chemotherapy with no diminution
in survival related to the delay in cystectomy. Copyright 2003

In the 1990s, the European Organization for Research and Treatment
of Cancer Genito-Urinary (EORTC GU) Group focused on dose-intensity
concepts of the methotrexate, vinblastine, doxorubicin, and cisplatin
(MVAC) regimen for patents with bladder cancer. In a randomized
trial in patients with advanced urothelial cell cancer, standard
MVAC was compared with 2-weekly intensified MVAC plus granulocyte-colony
stimulating factor (G-CSF) support. Although the dose-intensified
therapy resulted in a higher overall and complete response rates,
it did not result in a better median survival. In parallel, the
Spanish Oncology Genitourinary Group (SOGUG), in collaboration
with the EORTC GU Group, conducted Phase I and II trials to investigate
the feasibility and efficacy of the incorporation of two new active
agents, gemcitabine and paclitaxel, into two-drug or three-drug
cisplatin-based or carboplatin-based regimens. The EORTC GU Group
currently is conducting randomized studies of combined paclitaxel,
cisplatin, and gemcitabine compared with combined gemcitabine
plus cisplatin in patients with good performance status and good
renal function and studies of combined gemcitabine plus carboplatin
compared with combined carboplatin, methotrexate, and vinblastine
in patients who are unsuited for cisplatin. In the 1990s, the
EORTC coordinated a large Intergroup study of neoadjuvant cisplatin,
methotrexate, and vinblastine chemotherapy versus no chemotherapy
before definitive treatment. That study included 976 patients
and was based on a design to detect at least a 10% absolute improvement
in survival. The final results showed a 5.5% survival difference
at 3 years in the chemotherapy arm. The EORTC GU Group currently
is coordinating an Intergroup study that was designed to detect
an improvement of 7% in absolute survival in the adjuvant setting.

Adenovirus-mediated gene therapy for bladder cancer:
efficient gene delivery to normal and malignant human urothelial
cells in vitro and ex vivo.

Cancer Research UK Clinical Centre in Leeds, St. James's University
Hospital, Beckett Street, Leeds LS9 7TF, UK.
Existing local therapies for superficial transitional cell
carcinoma (TCC) of the bladder have limited success in preventing
progression to life-threatening, muscle-invasive disease, and
novel therapies are needed. Recent studies have raised doubts
concerning the feasibility of adenovirus-mediated gene therapy
for bladder cancer. We have therefore investigated adenoviral
transduction of normal and malignant human urothelial cells, both
as primary cultures and in intact epithelium.All 15 primary normal
human urothelial cell lines tested were transduced in vitro by
Adv-cmv-beta-gal at high efficiency, and better than most human
TCC cell lines. Eight primary human TCC explants were also successfully
transduced. In contrast, in intact normal urothelium, transduction
efficiency was lower, and occurred only in superficial epithelial
layers. Expression of the hCAR adenovirus receptor, however, occurred
throughout the full thickness of urothelium. Transduction of human
TCC biopsy specimens was at least as efficient as intact normal
urothelium.We demonstrate for the first time that adenoviral transduction
of both normal and malignant human urothelial cells is feasible.
A physical barrier, rather than hCAR status, may be the main determinant
of transduction of intact epithelium. Clinical trials of adenovirus-mediated
gene therapy for superficial bladder cancer are warranted.

Epirubicin and meglumine gamma-linolenic acid:
a logical choice of combination therapy for patients with superficial
bladder carcinoma.

BACKGROUND: Anthracyclines have been established as first-line
drugs for intravesical use in the treatment of patients with superficial
bladder carcinoma, although they result only in a modest reduction
in tumor recurrence rates. The essential fatty acid gamma-linolenic
acid (GLA) also is an effective cytotoxic agent against superficial
bladder carcinoma when it is applied topically. The objective
of this study was to assess the efficacy of combined epirubicin
and GLA with the purpose of developing a suitable model for modification
of existing intravesical regimens. METHODS: The human urothelial
carcinoma cell lines MGH-U1 and RT112 were used in standard cytotoxicity
assays and were exposed to meglumine GLA (MeGLA) and epirubicin
in two-dimensional concentration matrices. A thiozolyl blue (methyl-thiazoldiphenyl
tetrazolium) assay was used to determine residual cell biomass.
Drug interaction was quantified by median-effect analysis software
(CalcuSyn), and the evaluation of drug uptake utilized fluorescence
confocal microscopy (FCM) and flow cytometry. RESULTS: MeGLA caused
a significant enhancement of anthracycline uptake, viewed by FCM,
from 92 fluorescence units to 222 fluorescence units (P < 0.001).
Flow cytometry confirmed the increased drug uptake and showed
that the mean epirubicin content per cell increased from 23 to
57 units and from 8 to 24 units for MGH-U1 and RT112 cells, respectively
(99% confidence interval < 0.3). This resulted in improved
cytotoxicity, and it was shown that the drugs acted synergistically
with all but the highest MeGLA concentrations. CONCLUSIONS: The
efficacy of epirubicin was enhanced significantly when it was
used in combination with most concentrations of MeGLA (< 300
microg/mL), and the two agents acted synergistically. There was
a corresponding increase in epirubicin uptake by cells under these
conditions. At high MeGLA concentrations, however, anthracycline
solubility was compromised, and drug synergy was lost. Copyright

PURPOSE: To investigate the effect of pelvic lymph node dissection
and radical cystectomy for transitional cell cancer of the bladder
on recurrence-free and overall survival, pelvic recurrences, and
metastatic patterns in a homogeneous group. PATIENTS AND METHODS:
A consecutive series of patients undergoing pelvic lymphadenectomy
and radical cystectomy between 1985 and 2000 was analyzed. All
patients were staged N0, M0 preoperatively, and no patient received
neoadjuvant radio/chemotherapy. Pathologic characteristics based
on the 1997 tumor-node-metastasis system, recurrence-free/overall
survival, and metastatic patterns were determined. RESULTS: Five
hundred seven patients (age 66 +/- 12 years) with a mean follow-up
time of 45 months (range, 0.1 to 176 months) were analyzed. Five-year
recurrence-free and overall survival were, respectively, 73% and
62% for patients with organ-confined, lymph node-negative tumors
(n = 217; < or = pT2, pN0) and 56% and 49% for non-organ-confined,
lymph node-negative tumors (n = 166; > pT2, pN0). Positive
lymph nodes were found in 124 (24%) patients who had a 5-year
recurrence-free (33%) or overall (26%) survival. Isolated local
recurrences were observed in 3% of patients with organ-confined
tumors (< or = pT2, pN0), 11% with non-organ-confined tumors
(> pT2, pN0), and 13% with positive lymph nodes (any pT, pN+).
Distant metastases developed in 25% of patients with organ-confined
tumors, 37% with non-organ-confined tumors, and 51% with positive
lymph nodes. CONCLUSION: Despite negative preoperative staging,
pelvic lymphadenectomy and cystectomy for bladder cancer reveal
a high percentage of unsuspected nodal metastases (24%) that have
a 25% chance for long-term survival. This procedure also ensures
a low pelvic recurrence rate even in lymph node-positive patients,
and patients with locally advanced cancer have a 56% probability
of 5-year recurrence-free survival.

Johns Hopkins Hospital, Baltimore, MD, USA.
PURPOSE: To determine maximum-tolerated dose, toxicities, and
pharmacokinetics associated with weekly intravesical gemcitabine
therapy in patients with superficial bladder cancer. PATIENTS
AND METHODS: Fifteen patients with recurrent superficial transitional
cell bladder carcinoma who experienced prior intravesical therapy
failure were studied. Two to 4 weeks after complete transurethral
resection, gemcitabine was administered intravesically, once weekly
for 6 consecutive weeks. Dwell time was 2 hours. Pharmacokinetics
of gemcitabine and its metabolite, 2'2'-difluorodeoxyuridine (dFdU),
were studied in plasma and urine. Cystoscopy was repeated 6 weeks
after therapy. RESULTS: Three-patient cohorts were enrolled sequentially
at doses of 500, 1,000, and 1,500 mg in 100 mL 0.9% NaCl. Two
patients received 2,000 mg in 100 mL. An additional four patients
received 2,000 mg in 50 mL. No grade 4 toxicity or clinically
relevant myelosuppression was noted. Nine of 13 evaluable patients
were recurrence-free at 12 weeks. Low concentrations of gemcitabine
(< or = 1 microg/mL) were present transiently in plasma of
all patients receiving 2,000 mg in 50 mL. Gemcitabine was undetectable
in plasma of other patients. dFdU was undetectable in plasma of
patients receiving less than 1,500 mg. At doses > or = 1,500
mg, dFdU concentrations increased until 90 to 120 minutes and
then declined little, if any. Plasma dFdU concentrations implied
absorption of 0.5% to 5.5% of instilled dose. Between 61% and
100% of the gemcitabine dose was accounted for in voided urine.
No dFdU was measured in voided urine. CONCLUSION: Intravesical
gemcitabine, at doses up to 2 g/wk, is well tolerated, is associated
with minimal systemic absorption, and has promising efficacy in
treatment of superficial bladder cancer.

Prognostic significance of vascular and perineural
invasion in urothelial bladder cancer treated with
radical cystectomy.
Leissner J, Koeppen C, Wolf HK.
Department of Urology, Otto-von-Guericke-University, Magdeburg,
Germany.
PURPOSE: Data on the prognostic significance of tumor invading
lymphatic and blood vessels in bladder cancer are controversial,
while little is known about perineural invasion in this tumor.
We determined the prognostic value of these parameters in radical
cystectomy specimens. MATERIALS AND METHODS: Slides of 283 radical
cystectomy specimens obtained from 1986 to 1997 were examined
retrospectively with respect to tumor invasion in lymphatic and
blood vessels, and perineural spaces. This review was performed
while blinded to lymph node tumor involvement or the postoperative
disease course. The Kaplan-Meier probability analysis of tumor-free
survival and the log rank test were used to determine the prognostic
effects of vascular and perineural invasion. Multivariate analysis
using the Cox proportional hazards model was also performed. RESULTS:
Lymphatic, blood vessel and perineural tumor invasion were present
in 54.1%, 13.1% and 47.7% of specimens, respectively. Tumor progressed
in 46.3% of patients. On univariate analysis all 3 factors showed
strong prognostic significance. However, on multivariate analysis
only blood vessel invasion, invasion depth and regional lymph
node status were independent prognostic factors (p <0.05).
CONCLUSIONS: Lymph node metastases, pT classification and blood
vessel invasion are independent prognostic parameters of tumor-free
survival that should be used to guide patient treatment after
radical cystectomy. Invasion of the blood and lymphatic vessels
should be commented on separately in the pathology report.

Adenoviral-mediated retinoblastoma 94 produces
rapid telomere erosion, chromosomal crisis, and caspase-dependent
apoptosis in bladder cancer and immortalized human urothelial
cells but not in normal urothelial cells.
Zhang X, Multani AS, Zhou JH, Shay JW, McConkey D, Dong L, Kim
CS, Rosser CJ, Pathak S, Benedict WF.
Department of Genitourinary Medical Oncology, The University of
Texas M.D. Anderson Cancer Center, Houston, Texas 77030, USA.
Retinoblastoma (RB)94, which lacks the NH(2)-terminal 112 amino
acid residues of the full-length RB protein (RB110), is a more
potent tumor and growth suppressor than RB110. In this study,
Ad-RB94, but not Ad-RB110, produced marked growth inhibition,
cytotoxicity, caspase-dependent apoptosis, and G(2)-M block in
the human RB-negative, telomerase-positive bladder cancer cell
line UM-UC14. This effect was completely inhibited by pretreatment
with caspase inhibitors (P < 0.0001). Similar results were
seen in RB-positive and other RB-negative bladder cancer cell
lines. Ad-RB94 produced rapid telomere length shortening and loss
of telomere signal, which was associated with polyploidy and chromosomal
aberrations (P < 0.001). Ad-RB94, however, showed no cytotoxicity
to telomerase-negative human normal urothelium cells but was highly
cytotoxic to telomerase-positive human E6 and E7 immortalized
urothelial cells (P < 0.0001). In addition, telomerase-negative
cells, which maintain their telomere length through an alternative
lengthening of telomeres DNA recombination pathway, showed no
cytotoxicity to RB94. These results suggest that the induction
of rapid telomere erosion and chromosomal crisis by RB94 in telomerase-positive
cancer and in telomerase-expressing immortalized human cells is
a major factor in its selective and potent tumor suppression and
cytotoxic activity. The lack of cytotoxicity to normal cells should
also provide a high therapeutic index when used in gene therapy
protocols for the treatment of bladder and other cancers.

Extent of pelvic lymphadenectomy and its impact
on outcome in patients diagnosed with bladder cancer: analysis
of data from the Surveillance, Epidemiology and End Results Program
data base.
Konety BR, Joslyn SA, O'Donnell MA.
Department of Urology, University of Iowa, Iowa City, USA.
PURPOSE: The benefit of pelvic lymphadenectomy in patients
with bladder cancer remains controversial. We analyzed the impact
of lymphadenectomy on disease specific survival in a population
based sample of patients with bladder cancer who underwent radical
cystectomy. MATERIALS AND METHODS: Analysis included data on 1,923
patients who underwent radical cystectomy for bladder cancer between
1988 and 1996 obtained from the Surveillance, Epidemiology and
End Results program cancer registry. We analyzed the impact of
the number of lymph nodes examined, number of positive lymph nodes
and ratio of positive-to-total number of lymph nodes resected
on disease specific and overall survival independent of patient
age, gender, stage, race, radiation and chemotherapy. RESULTS:
Median followup in cystectomy cases was 63.5 months (range 0 to
131). Patients with 0 to 3 lymph nodes examined were at significantly
higher risk of death from bladder cancer than those with greater
than 3 (HR 1 to 1.2 versus 0.41 to 0.58). Patients with stages
I/in situ, III and IV disease benefited from more extensive lymphadenectomy.
In stage IV cases, while the total number of positive lymph nodes
removed did not correlate with increased survival, the proportion
of excised lymph nodes positive for metastatic bladder cancer
tended to correlate with the risk of death from the disease. CONCLUSIONS:
These results indicate significantly increased survival rates
after cystectomy in patients with bladder cancer diagnosed with
stages III or IV disease who have relatively more lymph nodes
examined, suggesting that even some with higher stage disease
may benefit from extended pelvic lymphadenectomy at cystectomy.

Superiority of ratio based lymph node staging
for bladder cancer.
Herr HW.
Department of Urology, Memorial Sloan-Kettering Cancer Center,
New York, New York, USA.
PURPOSE: The current study evaluated lymph node staging and
the outcome in patients with lymph node positive bladder cancer
after radical cystectomy. MATERIALS AND METHODS: A total of 162
patients with lymph node positive bladder cancer were followed
a median of 7.5 years after radical cystectomy and pelvic lymph
node dissection for survival and local recurrence. Lymph node
disease was stratified by pN stage, the number of positive lymph
nodes and the number of positive lymph nodes in relation to the
number removed (ratio based pN stage). RESULTS: A median of 13
lymph nodes (range 2 to 32) was examined, showing an average of
3.3 positive lymph nodes per specimen. An increased number of
lymph nodes correlated with the identification of lymph node positive
cases. The ratio of the number of positive-to-total number of
lymph nodes removed better defined surgical outcome than conventional
lymph node staging. CONCLUSIONS: Ratio based lymph node staging,
which reflects the number of lymph nodes examined and the quality
of lymph node dissection, was a significant prognostic variable
for survival and local control in patients with lymph node positive
bladder cancer after radical cystectomy.

T2a transitional cell carcinoma of the bladder:
long-term experience with intravesical immunoprophylaxis with
bacillus Calmette-Guerin.

I.
Deparment of Urology, University of Ulm, Germany.
PURPOSE: In this prospective study we evaluate the effect of
combined transurethral resection of early muscle invasive bladder
cancer and immunotherapy with bacillus Calmette-Guerin (BCG) in
patients unfit for radical cystectomy or refusing more aggressive
therapies. MATERIALS AND METHODS: A total of 22 patients with
a mean age 73.6 years were included in the study. Inclusion criteria
were histologically proven muscle invasive transitional cell carcinoma
of the bladder with a tumor-free second resection and negative
staging examinations in patients unfit for radical cystectomy
or refusing more aggressive therapies. All patients received 6
weekly instillations of 120 mg. BCG starting 14 to 21 days after
the last transurethral resection of the tumor. Followup at 3 months
included cystoscopy, urinary cytology, ultrasound of the abdomen
and chest x-ray. Every 6 months computerized tomography of the
abdomen and bone scans were performed. RESULTS: The overall 5-year
survival rate was 69.1%, while the disease specific 5-year survival
rate was 94%. One muscle invasive recurrence was noted at 69 months,
which was again treated with the same regimen but ultimately led
to radical cystectomy 21 months later. One patient died of progressive
recurrence in the upper urinary tract. The 5-year recurrence-free
survival rate was 46.5%. The only severe complication was BCG
pneumonitis. CONCLUSIONS: The data show encouraging results for
transurethral resection of bladder tumor with intravesical BCG
therapy in select patients with T2a bladder cancer who are not
candidates for radical cystectomy.

Pemetrexed in bladder, head and neck, and cervical
cancers.
Paz-Ares L, Ciruelos E, Garcia-Carbonero R, Castellano D, Lopez-Martin
A, Cortes-Funes H.
Department of Medical Oncology, Doce de Octubre University Hospital,
Madrid, Spain.
Pemetrexed is a novel multitargeted antifolate analog. The
drug has shown encouraging activity in a wide range of solid tumors,
including cervix, head and neck, and bladder carcinomas, which
are the focus of this review. Toxicity, particularly hematologic,
is higher in patients with these tumor types than in other populations
exposed to pemetrexed. Supplementation with folic acid and vitamin
B(12) appears to effectively reduce the incidence of severe toxicity
and may optimize the therapeutic index of pemetrexed in patient
subsets with poor nutritional status. The role of this agent in
the management of these and other tumor types, as a single agent
or in combination, shall be determined by randomized phase III
studies. Copyright 2002, Elsevier Science (USA). All rights reserved.

[Treatment of superficial transitional cell bladder
carcinoma. Long-term results of trial comparing transurethral
resection alone and adjuvant chemotherapy with Doxorubicin]
[Article in Lithuanian]

Gudinaviciene I.
Urology Clinic of Kaunas Medical University, Lithuania.
OBJECTIVE: We compared the efficacy of transurethral resection
alone or transurethral resection followed by bladder instillations
of Doxorubicin for 1 year in patients with superficial bladder
carcinoma, and followed them long term for the incidence of recurrence
and progression to muscle invasion. MATERIALS AND METHODS: Between
December 1998 and December 2000 a total of 69 patients with superficial
transitional cell carcinoma of bladder participated in this prospective
study. Final analysis of treatment results included 64 patients.
Doxorubicin was administered to 25 patients, 39 patients were
treated only by TUR. Patients were followed by control cystoscopy.
RESULTS: The mean follow-up was 22.95 months; SD 7.79. Mean time
to first recurrence in Doxorubicin group was 14.14 months; SD
7.84, in TUR alone group - 7.61 months; SD 4.4; p>0.05. Disease
free survival was significantly prolonged in Doxorubicin group;
p<0.05. There are no significant difference to comparison recurrence
rate and progression rate between two groups. CONCLUSIONS: In
regard to time of first recurrence and disease free survival this
study indicates that adjuvant chemotherapy with Doxorubicin is
superior to transurethral resection alone. However, progression
in stage or recurrence rate was not influenced by the treatment
regimen.

cancer and its relationship with P-glycoprotein and apoptotic
factors.

BACKGROUND: Intravesical treatment with mitomycin C (MMC) leads
to a complete response rate of around 40% in superficial bladder
cancer (TCC). In order to determine in advance which patients
will fail to respond, we describe a study assessing the feasibility
of applying the ATP assay to test the chemosensitivity of samples
from patients with this disease. MATERIALS AND METHODS: TURBT
or biopsy samples were received from 27 patients, 23 of which
were suitable for the ATP assay (16 primary tumours and 7 recurrences).
RESULTS: The success rate of the assay was 91%. There was a marked
variation in the effect of MMC between patients with a > 50-fold
range in LC50 values (drug concentration required to kill 50%
of cells) from 2.99- > 150 microM with a median value of 22.4
microM. We were unable to determine any overall correlation between
chemosensitivity and tumour stage or grade or the treatment status
of the patient in this small data set. P-glycoprotein status and
caspase-3 levels were assessed on these samples using immunohistochemistry
but there did not appear to be any relationship between either
of these parameters and MMC resistance. Apoptotic counts and mitotic
counts were also measured but, whilst these appeared to correlate
with grade (p < 0.01), there was no overall significant relationship
established with MMC chemosensitivity. CONCLUSION: This study
suggests that it is possible to use the ATP assay for chemosensitivity
testing in TCCs. Despite a lack of overall correlation between
ex vivo MMC resistance and the conventional prognostic factors
tested, further studies are warranted in a larger data set to
test the ability of this technique to predict clinical outcome
in this disease.

Over expression of metallothionein predicts resistance
of transitional cell carcinoma of bladder to intravesical mitomycin
therapy.
Lynn NN, Howe MC, Hale RJ, Collins GN, O'Reilly PH.
Department of Urology, Stepping Hill Hospital, Stockport, United
Kingdom.
PURPOSE: Metallothionein, a low molecular weight intracellular
protein, binds mitomycin with high affinity protecting the tumor
DNA. We prospectively studied the relationship of metallothionein
expression in bladder transitional cell carcinoma and resistance
to intravesical mitomycin. MATERIALS AND METHODS: A series of
45 consecutive patients with superficial transitional cell carcinoma
treated with intravesical mitomycin were studied. Resected tumor
tissues were stained with metallothionein monoclonal antibody
E9. Two pathologists scored staining intensity and distribution.
All patients were followed with regular flexible cystoscopy. RESULTS:
Median patient age was 73 years (range 44 to 89). Tumor grade
was 1 to 3 in 6, 33 and 6 cases, respectively. In 20 patients
(44.44%) tumor recurred after mitomycin therapy. Median cytoplasmic
staining scores for recurrent and nonrecurrent tumors were 5 (range
0 to 61) and 0 (0 to 14), respectively. Median nuclear staining
scores for recurrent and nonrecurrent tumors were 3 (range 0 to
56) and 0 (0 to 11), respectively. Median followup of patients
without recurrence was 18 months (range 12 to 36). Nuclear and
cytoplasmic staining scores were significantly higher in recurrent
than in nonrecurrent tumors. There was no significant relationship
of metallothionein expression with tumor grade. CONCLUSIONS: Over
expression of metallothionein predicts the resistance of bladder
transitional cell carcinoma to intravesical mitomycin therapy.

Combination chemotherapy with newer, more active drugs in patients
with advanced and/or metastatic bladder cancer might show improved
response rate and survival. Gemcitabine (GEM) and Epidoxorubicin
(EPI) have demonstrated activity in this disease. In addition,
experimental studies in vitro have shown that the two agents have
additive-synergistic effects when used in combination. Our prior
phase I dose-finding study in previously untreated patients with
advanced or metastatic bladder cancer defined recommended doses
for further trials of GEM 1000 mg/m2 and EPI 25 mg/m2 on days
1, 8 and 15 every 28 days. A phase II trial at this dose level
was initiated in previously untreated patients to assess efficacy
and toxicity. Eligible patients had measurable disease; Karnofsky
performance status (PS) of > 40; no prior chemotherapy; and
adequate bone marrow reserve, cardiac, hepatic and renal function.
Thirty- one patients (22 males, 9 females) with median age of
64 (range 44-75) and median PS of 80 were accrued, and all were
eligible. Twelve patients had T4N1-2 M0, 8 had lymph node only
metastases, while 11 had visceral metastases (liver, bone, lung).
A total of 181 cycles was administered (range 3-7 per patient).
Major toxicities (WHO grade > or = 3) were: neutropenia in
5 patients, thrombocytopenia in 2 patients, and anemia in 2 patients.
Three patients had febrile neutropenic episodes and only 3 patients
required dose reduction. Grade 1-2 non-hematological toxicities
included nausea/vomiting, stomatitis and alopecia. No cardiac
toxicity was observed. Of the 30 response evaluable patients,
17 (57%) demonstrated a major response (3 complete and 14 partial)
(95% CI: 39%-75%), 7 had stable disease (23%) and 6 progressed
(20%). These preliminary results confirm the phase I observation
that the combination of GEM--EPI is highly active in the treatment
of advanced and metastatic bladder cancer with a favourable toxicity
profile.

INTRODUCTION: The glycoprotein P-170, causing drug efflux from
the cells, may represent at least one cause of resistance to most
drugs used in intravesical chemotherapy of superficial bladder
cancer. MATERIALS AND METHODS: GP-170 was retrospectively assessed
in 60 patients affected by superficial transitional cell tumours
of the bladder. It was assessed by immunohistochemistry in a semiquantitative
way by the intensity of staining and by the percentage of positive
cells. Correlation of GP-170 expression with G-grade, T-category,
multiplicity, recurrence rate and treatment was investigated.
In 44 patients recurrence was analysed in relation to GP-170 basal
expression and to its variations. The monoclonal antibody JSB1
(DBA) at 1:20 dilution was employed for the GP-170 assay. RESULTS:
GP-170 expression increases with grade but was lower in multiple
tumours. No difference between Ta and T1 categories was detected.
GP-170 immunohistochemistry from different portions of the same
tumour showed a very marked variability in 35.7% of patients.
Seven patients (11.6%) were totally negative for GP-170. No statistically
significant correlation was found between recurrence, progression
and GP-170 basal expression. Similarly no correlation emerged
between grade and stage variations at recurrence and modifications
in GP-170 expression. One third of the tumours recurring after
chemotherapy were negative for GP-170 in spite of an increase
in recurrence rate and other risk factors. CONCLUSION: At the
present stage of our experience, we have been unable to show that
GP-170 is a useful marker for monitoring chemoresistance to intravesical
chemotherapy in superficial bladder cancer. Furthermore, GP-170
determination has shown several technical difficulties.

[Combination chemotherapy with ifosfamide, 5-fuluorouracil,
etoposide and cisplatin for advanced urothelial cancer: the treatment
results and significance of tumor marker evaluation in response
assessment of chemotherapy]
[Article in Japanese]
Maezawa T, Yonese J, Tsukamoto T, Ishii N, Fukui I.
Department of Urology, Cancer Institute Hospital, Tokyo, Japan.
PURPOSE: We investigated treatment results of IFEPchemotherapy
in patients with advanced urothelial cancer (N2-3, M1) and the
usefulness of measuring serum CEA, CA19-9 and SCC to evaluate
the treatment response of chemotherapy. PATIENTS AND METHODS:
From March 1994 to May 2000, we treated 41 patients with IFEP
therapy consisting of ifosfamide (2 g/m2), 5-fluorouracil (750
mg/m2), etoposide (100 mg/m2) and cisplatin (20 mg/m2), all of
which were given daily for 3 consecutive days every 3 weeks. Before
initiating the chemotherapy, serum CEA, CA19-9 and SCC were measured.
And in patients with high pretreatment serum concentration, they
were serially evaluated and compared with the tumor response assessed
by imaging studies and the patients' clinical course. RESULTS:
The response rate of the chemotherapy was 53.7% (CR + PR), with
a median survival period being 10.8 months and a median duration
of response for the 22 responders being 7.5 months. One and three-year
survival rates of all the patients were 59.3% and 16.5%. Response
rates of primary tumors and metastatic lesions to the lymph node,
bone, lung and liver were in 54% and 57%, 56%, 50% and 40%, respectively.
Bone marrow toxicity was significant with 1 drug-related death.
Before chemotherapy, tumor marker was elevated in 19 patients:
CEA in 7, CA19-9 in 13 and SCC in 10. Serum levels of the tumor
markers were related neither to the primary and metastatic tumor
sites nor to patient's survival time. However, decline of serum
tumor markers after chemotherapy was well related to response
of the tumor assessed by imaging studies. CONCLUSION: IFEP chemotherapy
appears to be active in the treatment of advanced urothelial tumor
and serial measurement of serum CEA, CA19-9 and SCC may be useful
in judgement of tumor response to the chemotherapy.

surgery for bladder cancers.
Sun X, Hu J, Yang Q.
Department of Radiation Oncology, Sir Run Run Shaw Hospital, College
of Medicine, Zhejiang University, Hangzhou 310016, China. sunxiaonan@hotmail.com
OBJECTIVE: To analyze the efficacy of recurrence prophylaxis
using radiation and chemotherapy following bladder conservation
surgery for muscle invasive bladder cancer. METHODS: 23 patients
with muscle invasive bladder cancer were treated with radiotherapy
combined with bladder mitomycin infusion after bladder conservation
surgery (study group). Radiotherapy was given using an external
beam at an average dose of 5148 +/- 462 cGy with conventional
fractionation. For comparison, 29 similar patients treated with
postoperative bladder mitomycin infusion without radiation served
as control (control group). All patients were followed up for
more than 3 years, an average of 41.6 months (36 - 60 months).
RESULTS: The 3-year pelvic recurrent rate of muscle invasive bladder
cancer was 17.4% in the study group and 44.8% (P = 0.036) in the
control group. The 3-year distant metastasis rates were 17.4%
and 24.1%, respectively (P = 0.554). The 3-year overall survival
rates were 81.8% and 86.2%, respectively (P = 0.670). Two patients
from the study group had their treatment interrupted, one for
3 days and the other for one week due to acute cystitis, while
the rest of the patients were able to complete the treatment according
to schedule. CONCLUSION: Radiotherapy plus chemotherapy after
bladder conservation surgery for muscle invasive bladder cancer
can decrease the rate of pelvic recurrence effectively and be
used as a realistic adjuvant treatment.

OBJECTIVE: We describe the results of an organ-sparing approach
for the treatment of non-metastatic, invasive bladder carcinoma.
MATERIAL AND METHODS: Twenty-three patients (mean age 71 years;
age range 47-87 years) with bladder carcinoma of clinical stage
T2-T3N0M0 and histologically proven muscle invasion were examined
between 1992 and 1998. The median duration of follow-up was 30
months. The treatment protocol for intra-arterial chemotherapy
consisted of methotrexate 30 mg/m(2) and cisplatin 50 mg/m(2)
in 7 patients and cisplatin 50 mg/m(2) in 16 patients, administered
in three cycles via catheters inserted in the internal iliac arteries.
Concomitantly, 41.4 Gy of radiotherapy was given to the lesser
pelvis. Transurethral biopsy and urine cytology were performed
after the completion of treatment; patients were followed observationally
if residual tumor was absent, and underwent radical cystectomy
if it was present. RESULTS: At the end of treatment, 18 patients
(78%) showed a complete response (CR) and the bladder was spared
in all cases. Radical cystectomy was performed for 4 non-CR cases,
with the result that 2 cases had residual superficial cancer and
the other 2 had muscle-invading cancer histologically. Among the
patients with a CR, 2 experienced intravesical recurrence. Overall,
2 patients died of cancer, 5 died of other causes and 2 died during
treatment. The 5-year disease-specific survival rate was 70.3%
and the overall survival rate 46.4%. CONCLUSIONS: A bladder-sparing
approach for the treatment of muscle-invading bladder carcinoma
which utilizes combined intra-arterial chemotherapy and radiotherapy
may arrest the decline in quality of life induced by urinary diversion
and yield equivalent therapeutic benefit to that of radical cystectomy.

Muscle-invasive bladder cancer in elderly-unfit
patients with concomitant illness: can a curative radiation therapy
be delivered?

A, Delia P, Palazzolo C, Romeo A, Sansotta G, Pergolizzi S.
Department of Radiological Sciences, University of Messina, Italy.
AIMS AND BACKGROUND: There is no standard treatment for elderly-unfit
patients with muscle-invasive bladder cancer. Pelvic irradiation
alone is an usual approach in this instance, and some reports
have demonstrated that curative radiotherapy is feasible in elderly
patients. To our knowledge, no data exist about the feasibility
of a curative treatment in elderly patients with concomitant illness
and a Charlson Comorbidity Index (an index of comorbidity that
includes age) greater than 2. The main purpose of the present
study was to establish the feasibility of irradiation in a cohort
of elderly patients in poor general condition. METHODS: The records
of 45 elderly-unfit patients (median age, 75 years; range, 70-85),
with a comorbid Charlson score >2, treated with curative dose,
planned continuous-course, external beam radiotherapy for muscle-invasive
bladder cancer were reviewed. The patients were treated to a median
total dose of 60 Gy (range, 56-64), with an average fractional
dose of 190 +/- 10 cGy using megavoltage (6-15 MV). All patients
were treated with radiation fields encompassing the bladder and
grossly involved lymph nodes with a radiographic margin of at
least 1.5 cm. RESULTS: No treatment-related mortality and clinically
insignificant acute morbidity was recorded. No patient was hospitalized
during or after the irradiation because of gastrointestinal or
urogenital side effects. In one patient a week rest from therapy
was necessary due a febrile status. Median survival was 21.5 months;
overall 3- and 5-year survival was 36% and 19.5%, respectively.
CONCLUSIONS: Elderly-unfit patients with comorbidities and >70
years of age can be submitted to radical pelvic irradiation. The
results observed in this retrospective analysis have encouraged
us to use non-palliative radiotherapy doses in these patients
with muscle-invasive bladder cancer.

A phase I study of intravesical suramin for the
treatment of superficial transitional cell carcinoma
of the bladder.
Uchio EM, Linehan WM, Figg WD, Walther MM.
Urologic Oncology Therapeutic Branch, Center for Cancer Research,
National Cancer Institute/NIH, Bethesda, MD, USA.
PURPOSE: Suramin is a polysulfonated naphthylurea that inhibits
proliferation and DNA synthesis of transitional cell carcinoma
cell lines. Its large molecular size and negative charge inhibit
bladder absorption, making suramin an excellent candidate for
intravesical chemotherapy. Intravesical suramin was evaluated
in a phase I study to define dose limiting toxicity and systemic
absorption, determine a starting dose and regimen for phase II
studies and provide a preliminary assessment of in vivo antitumor
activity. MATERIALS AND METHODS: Intravesical suramin treatment
was administered in 9 patients with histologically identified
transitional cell carcinoma (Tcis, Ta or T1) in whom at least
1 course of standard intravesical chemotherapy (bacillus Calmette-Guerin,
thiotepa or mitomycin C) had failed. Suramin was administered
once weekly for 6 weeks. Patients were treated in groups of 3
using a 60 cc volume and intrapatient dose escalation schedule.
Suramin doses of 0.3 to 614.4 mg./ml. were administered intravesically.
The last group was treated with the same weekly dose for 6 weeks.
RESULTS: The 9 patients underwent 54 treatments with suramin.
Plasma suramin concentration after treatment was 1.9 to 38.0 microg./ml.
and was not related to treatment dose. The dose escalation phase
was limited by the solubility of suramin in solution. Complications
included self-limited bladder spasms (less than 24 hours) in 4
of 54 treatments (7%) and new or worsening vesicoureteral reflux
in 3 ureters (17%). Another patient who was treated after the
Foley balloon was inflated in the urethra experienced bladder
spasms, skin flushing and fever (39C). Mean bladder capacity before
and after treatment was 600 and 540 ml., respectively. At followup
7 patients had stage Ta tumors and 2 had carcinoma in situ. CONCLUSIONS:
An intravesical suramin dose of 153 mg./ml was defined as a safe
treatment parameter with acceptable plasma concentrations and
minimal side effects. Phase II studies are needed to assess the
antitumor activity of suramin in patients with transitional cell
carcinoma of the bladder.

Orthotopic urinary diversion after cystectomy
for bladder cancer: implications for cancer control and patterns
of disease recurrence.
Yossepowitch O, Dalbagni G, Golijanin D, Donat SM, Bochner BH,
Herr HW, Fair WR, Russo P.
Department of Urology, Memorial Sloan-Kettering Cancer Center,
New York, NY, USA.
PURPOSE: The impact of orthotopic urinary diversion on the
quality of cystectomy and ensuing cancer control has not been
adequately studied. We analyzed our experience with this clinical
problem. MATERIALS AND METHODS: The records of 214 patients who
underwent cystectomy and orthotopic diversion for bladder cancer
were retrospectively evaluated and compared with those of 269
treated with an ileal conduit. Analyzed end points included overall
and cancer specific survival. We specifically assessed the patterns
of relapse and their association with pathological findings at
cystectomy in the neobladder group. RESULTS: No cancer specific
survival difference was identified in the neobladder and ileal
conduit cohorts when adjusting for pathological stage. Patterns
of relapse in 62 of the 214 patients with a neobladder (29%) included
local recurrence in 23 (11%), distant recurrence in 19 (9%), and
combined local and distant recurrence in 18 (8%). Urethral recurrence
was rare (2%). Of 10 patients (4.6%) diagnosed with upper tract
recurrence 6 and 4 initially had relapse in the ureteroenteric
anastomosis and renal pelvis, respectively. Five of the 6 patients
with anastomotic relapse had evidence of disease in the intramural
or juxtavesical ureter that was removed en bloc with the cystectomy
specimen. Only 1 patient required neobladder takedown after such
anastomotic recurrence. CONCLUSIONS: These results indicate that
neobladders do not compromise the quality of preceding cystectomy
or interfere with management in the presence of local or distant
disease relapse. Our data suggest that involvement of the intramural
or juxtavesical ureteral segment at cystectomy irrespective of
surgical margin status may identify patients at higher risk for
anastomotic recurrence, which is associated with an ominous prognosis.

An interval longer than 12 weeks between the diagnosis
of muscle invasion and cystectomy is associated with worse outcome
in bladder carcinoma.
Sanchez-Ortiz RF, Huang WC, Mick R, Van Arsdalen KN, Wein AJ,
Malkowicz SB.
Division of Urology, Department of Surgery, University of Pennsylvania
Medical Center, Philadelphia, PA, USA.
PURPOSE: The standard of care for muscle invasive transitional
cell carcinoma of the bladder is radical cystectomy. Definitive
therapy may often be delayed for various reasons. We assessed
whether pathological stage and survival correlated with the length
of time between diagnosis of muscle invasion and cystectomy. MATERIALS
AND METHODS: The records of 290 consecutive patients who underwent
radical cystectomy between February 1987 and July 2000 were reviewed.
Of 265 (91.4%) cystectomies performed for transitional cell carcinoma
data were available for 247 (85.2%) and 189 (65.2%) patients were
identified who underwent surgery for muscle invasive disease (T2
or greater). The interval between diagnosis of muscle invasion
and cystectomy was calculated for each patient. Patients were
divided into groups based on time to surgery as group 1-less than
4 weeks, 2-4 to 6 weeks, 3-7 to 9 weeks, 4-10 to 12 weeks, 5-13
to 16 weeks, and 6-greater than 16 weeks. Exploratory univariate
and multivariate analyses were performed to test the association
of time lag with clinical features and postoperative survival.
RESULTS: Mean patient age was 66 years (range 37 to 84) and overall
3-year Kaplan-Meier estimated survival was 59.1% +/- 4% (median
followup 36 months). For all patients mean interval from diagnosis
to cystectomy was 7.9 weeks (range 1 to 40). Extravesical disease
(P3a or greater) or positive nodes were identified in 84% (16
of 19) of patients when the delay was longer than 12 weeks, compared
with 48.2% (82 of 170) in those with a time lag of 12 weeks or
less (p < 0.01). Similarly 3-year estimated survival was lower
(34.9% +/- 13.5%) for patients with a surgery delay longer than
12 weeks compared to those with a shorter interval 62.1% +/- 4.5%
(hazards ratio 2.51, 95% CI 1.30-4.83, p = 0.006). When adjusted
for nodal status, and clinical and pathological stages the interval
was still statistically significant (adjusted hazards ratio 1.93,
95% CI 0.99-3.76, p = 0.05). CONCLUSIONS: In patients undergoing
radical cystectomy a delay in surgery of greater than 12 weeks
was associated with advanced pathological stage and decreased
survival. Although this relationship persisted after adjusting
for nodal status, and clinical and pathological stages, the presence
of lymph node metastasis remained the strongest predictor of patient
outcome.

The impact of co-morbid disease on cancer control
and survival following radical cystectomy.
Miller DC, Taub DA, Dunn RL, Montie JE, Wei JT.
Department of Urology, University of Michigan, Ann Arbor, MI,
USA.
PURPOSE: We clarified the impact of concurrent medical disease
on tumor control and survival following radical cystectomy. MATERIALS
AND METHODS: A total of 106 consecutive patients with clinically
localized (cT2 or less) disease underwent radical cystectomy at
the University of Michigan between 1997 and 1998. The Charlson
Index, a validated risk adjustment index, was used to assess preoperative
co-morbidity. The 3 primary end points were pathological stage,
disease specific survival and overall survival. Logistic regression
models were used to determine the relationship between Charlson
Index and pathological stage, while Cox regression models were
used for the 2 survival end points. RESULTS: Of our study population
24% had a Charlson Index score of 2 or greater. Myocardial infarction,
nonurothelial solid malignancies and cerebrovascular disease were
the most common co-morbid conditions at 14%, 12% and 10%, respectively.
On bivariate analysis the Charlson Index was significantly associated
with decreased disease specific (p = 0.049) and overall (p = 0.016)
survival. In a multivariate model the index was independently
associated with decreased cancer specific survival (p = 0.049)
and increased risk of extravesical disease (p = 0.033). CONCLUSIONS:
We demonstrated an association between co-morbid illness and adverse
pathological and survival outcome following radical cystectomy.
This finding underscores the value of assessing overall health
before recommending and proceeding with surgery. Moreover, our
results emphasize the need to adjust for co-morbidity when comparing
outcomes following radical cystectomy.

Complications of radical cystectomy for nonmuscle
invasive disease: comparison with muscle
invasive disease.
Cookson MS, Chang SS, Wells N, Parekh DJ, Smith JA Jr.
Department of Urologic Surgery, Vanderbilt University Medical
Center, Nashville, TN, USA.
PURPOSE: Radical cystectomy is gold standard treatment for
muscle invasive bladder cancer and is an option for many patients
with nonmuscle invasive disease at high risk for disease progression.
We assessed the early complications of radical cystectomy among
patients with nonmuscle invasive compared to those with muscle
invasive disease. MATERIALS AND METHODS: We reviewed the records
of 304 consecutive patients who underwent radical cystectomy from
December 1995 to July 2000. We evaluated complications that occurred
within 30 days of the procedure. Cases were stratified into nonmuscle
invasive (PO, Pa, P1 and PIS, N0) or muscle invasive (P2-4, N0-3)
tumors based on final specimen pathology. The 2 groups were then
compared with respect to age, gender, race, American Society of
Anesthesiologists score, type of urinary diversion, estimated
blood loss, operative time and length of stay, and major and minor
complications. RESULTS: Of the 293 available patients 105 (36.8%)
had nonmuscle invasive specimen pathology. Overall major and minor
complications occurred in 4.9% and 30.4% of cases, respectively.
Independent t test revealed no significant difference between
groups in terms of age (p = 0.85), gender (p = 0.77), race (p
= 1.0), American Society of Anesthesiologists (p = 0.32), type
of urinary diversion (p = 0.33), estimated blood loss (p = 0.31),
operative time (p = 0.41), length of stay (p = 0.75), or presence
of major (p = 0.78) or minor (p = 0.79) complications. CONCLUSIONS:
The early morbidity associated with radical cystectomy for nonmuscle
invasive disease is similar to but not less than that associated
with muscle invasive tumors. These acceptable risks as well as
the potential benefits should be discussed with patients with
nonmuscle invasive bladder cancer at high risk for disease progression.

A retrospective analysis of 153 patients treated
with or without intravesical bacillus Calmette-Guerin for primary
stage T1 grade 3 bladder cancer: recurrence, progression and survival.
Shahin O, Thalmann GN, Rentsch C, Mazzucchelli L, Studer UE.
Department of Urology, Institute of Pathology, University of Bern,
Inselspital, Bern, Switzerland.
PURPOSE: We retrospectively evaluated the long-term outcome
in patients with newly diagnosed stage T1 grade 3 bladder cancer
treated with transurethral resection with or without intravesical
bacillus Calmette-Guerin (BCG). MATERIALS AND METHODS: Of 153
patients with a median age of 67 years (range 36 to 88) and a
male-to-female ratio of 4:1 we treated 92 with transurethral bladder
resection and additional BCG, and 61 with transurethral bladder
resection alone. BCG was administered intravesically as 120 mg.
BCG Pasteur F dissolved in 50 ml. saline, retained for up to 2
hours weekly for 6 weeks and repeated as necessary. RESULTS: Median
followup was 5.3 years (range 0.4 to 18.2). Disease recurred in
70% of the patients treated with BCG and in 75% treated with transurethral
resection alone. Median time to recurrence was 38 and 22 months
for BCG and resection alone (p = 0.19). Tumor progressed in 33%
of patients with BCG and in 36% with resection alone. Deferred
cystectomy was performed in 29% of the patients with BCG and in
31% with resection alone. Overall and disease specific survival
did not differ significantly. CONCLUSIONS: Our results suggest
that intravesical BCG therapy after transurethral bladder resection
for stage T1 grade 3 bladder cancer may delay the time to recurrence
and cystectomy but it does not substantially alter the final outcome.
Our findings reflect the rule of 30% for stage T1 grade 3 cancer,
namely approximately 30% of patients never have recurrence, 30%
ultimately die of metastatic disease and 30% require deferred
cystectomy.

Intravesical bacillus Calmette-Guerin versus mitomycin
C for superficial bladder cancer: a formal meta-analysis of comparative
studies on recurrence and toxicity.
Bohle A, Jocham D, Bock PR.
Department of Urology, Medical University of Lubeck, Lubeck, Germany.
PURPOSE: We compare the therapeutic efficacy and toxicity of
intravesical bacillus Calmette-Guerin (BCG) with mitomycin C on
recurrence of stages Ta and T1 bladder carcinoma. MATERIALS AND
METHODS: Combined published and unpublished data from comparative
studies on BCG versus mitomycin C for superficial bladder carcinoma
considering possible confounding factors were analyzed. Odds ratio
(OR) and its 95% CI were used as primary effect size estimate.
Toxicity data were evaluated descriptively. RESULTS: In 11 eligible
clinical trials 1,421 patients were treated with BCG and 1,328
were treated with mitomycin C. Within the overall median followup
time of 26 months 38.6% of the patients in the BCG group and 46.4%
of those in the mitomycin C group had tumor recurrence. In 7 of
11 studies BCG was significantly superior to mitomycin C, in 3
studies no significant difference was found, while in 1 study
mitomycin C was significantly superior to BCG. An overall statistically
significant superiority of BCG versus mitomycin C efficacy in
reducing tumor recurrence was detected (OR 0.56, 95% CI 0.38 to
0.84, p = 0.005). In the subgroup treated with BCG maintenance
all 6 individual studies showed a significant superiority of BCG
over mitomycin C (OR 0.43, 95% CI 0.35 to 0.53, p <0.001).
In 4 of the 5 studies with reported data on toxicity BCG associated
cystitis was significantly more frequent than in the mitomycin
C group (53.8% versus 39.2%). The combined cystitis OR was 1.81
(95% CI 1.48 to 2.23, p <0.001). The OR for cystitis in the
BCG maintenance group did not significantly differ from that in
the nonmaintenance therapy group. CONCLUSIONS: The results suggest
superiority of BCG over mitomycin C for prevention of tumor recurrences
in the combined data and particularly in the BCG maintenance treatment
subgroup, irrespective of the actual (intermediate or high) tumor
risk status. The toxicity with BCG is higher but does not differ
between BCG maintenance and nonmaintenance groups.

Do patients profit from 5-aminolevulinic acid-induced
fluorescence diagnosis in transurethral resection of bladder carcinoma?
Filbeck T, Pichlmeier U, Knuechel R, Wieland WF, Roessler W.
Department of Urology, St. Joseph's Hospital, Regensburg, Germany.
OBJECTIVES: To evaluate in a prospective study the influence
of fluorescence diagnosis (FD) controlled transurethral resection
of bladder tumors on therapeutic consequences. The aim was to
determine in how many patients FD led to a change in treatment
strategy compared with conventional white light (WL) cystoscopy.
METHODS: A total of 279 patients with suspected bladder tumors
underwent transurethral resection using FD in addition to WL cystoscopy.
The number of additional tumor-positive patients, staging change,
number of multilocular tumors exclusively detected by FD, and
resulting therapeutic consequences compared with the results after
WL cystoscopy were investigated. In addition a biopsy-based evaluation
was performed. RESULTS: Tumor or dysplasia II degrees (moderate
dysplasia) was detected in 177 patients. In 168 patients, tumor
was detected by WL cystoscopy, and in 9 (5.1%) of the patients,
tumor was completely overlooked by WL cystoscopy and diagnosed
exclusively by FD (n = 3 TaG1-G2, n = 2 carcinoma in situ, n =
1 greater than T1, and n = 3 dysplasia II degrees ). Multilocular
tumor involvement was detected in 10 cases using FD, and a change
in the stage by detection of coexisting dysplasia II degrees and
carcinoma in situ occurred in 8 patients. In 27 patients (15.3%),
additional information was obtained by exclusive detection of
tumors by FD. This resulted in a change in the treatment strategy
for 16 patients (9%). CONCLUSIONS: FD leads to an improvement
in the diagnosis of bladder carcinoma. It allows the early selection
of the best treatment option and thus has a potentially positive
effect on the prognosis of the affected patients.

The role of systemic chemotherapy in the management
of muscle-invasive bladder cancer.
Juffs HG, Moore MJ, Tannock IF.
Princess Margaret Hospital, Ontario, Toronto, Canada.
Patients with localised but muscle-invasive transitional-cell
carcinoma (TCC) of the bladder are at high risk of relapse and
death from metastatic disease after local treatment by cystectomy,
radiation, or both. Despite improvements in treatment, patients
with metastatic TCC have a median survival of about a year. TCC
is quite sensitive to chemotherapy, and patients are able to tolerate
newer regimens such as gemcitabine plus cisplatin better than
older regimens such as methotrexate, vinblastine, doxorubicin,
and cisplatin. However, the role of chemotherapy in the management
of locally advanced muscle-invasive TCC remains uncertain. Most
trials of neoadjuvant or adjuvant chemotherapy have shown no significant
improvement in survival, but many of these studies had suboptimum
design, evaluated chemotherapy that was less effective than regimens
in current use, and had sample sizes that were too small for important
changes in survival to be detected or ruled out. Recent trials
show trends in the direction of improved survival when optimum
chemotherapy is used. Large trials that recruit more than 1000
patients are required to assess the effectiveness of adjunctive
chemotherapy, and a large intergroup trial is in progress. Other
trials should address the role of molecular markers in selecting
patients for chemotherapy. Whenever possible, chemotherapy for
locally advanced muscle-invasive TCC should be given in the context
of a well-designed clinical trial.

ARCON: a novel biology-based approach in radiotherapy.
Kaanders JH, Bussink J, van der Kogel AJ.
Department of Radiation Ocology of the University Medical Centre
Nijmegen, Nijmegen, Netherlands. j.kaanders@rther.umcn.nl
Two mechanisms of radiotherapy resistance which are of major
importance in various tumour types are tumour-cell repopulation
and hypoxia. ARCON (accelerated radiotherapy with carbogen and
nicotinamide) is a new therapeutic strategy that combines radiation
treatment modifications, with the aim of counteracting these resistance
mechanisms. To limit clonogenic repopulation during therapy, the
overall duration of the radiotherapy is reduced, generally by
delivering several fractions per day. This accelerated radiotherapy
is combined with inhalation of hyperoxic gas to decrease diffusion-limited
hypoxia, and nicotinamide, a vasoactive agent, to decrease perfusion-limited
hypoxia. Preclinical studies have been done to test the enhancing
effects of these three components of ARCON, individually and in
combination, in several experimentally induced tumours and normal
tissues. In a mouse mammary carcinoma, the tumour-control rate
obtained with ARCON was the same as that with conventional treatment,
but with a radiation dose almost 50% lower. Phase 1 and 2 clinical
trials have shown the feasibility and tolerability of ARCON, and
have produced promising results in terms of tumour control. In
particular in cancers of the head and neck and bladder, the local
tumour-control rates are higher than in other studies, and phase
3 trials for these tumour types are underway. In conjunction with
these trials, hypoxia markers detectable by immunohistochemistry
are being tested for their potential use in predictive assays
to select patients for ARCON and other hypoxia-modifying therapies.

[Features of BCG-therapy in treating patients
with superficial bladder cancer]
[Article in Russian]
Chepurov AK, Murshudli ECh, Mazo EB.
AIM: To specify features of BCG-therapy which may predict effectiveness
of the treatment and optimize the treatment regimen. MATERIAL
AND METHODS: Intravesical immunotherapy with imuron (a 6-week
course) was conducted in 62 patients with superficial cancer of
the urinary bladder who had undergone surgical treatment and were
prognostically poor. 51 patients of group 1 received maintenance
therapy as 3 weekly instillations each 3 months for the first
year followed by once in 6 months. 11 patients of group 2 received
single monthly instillations. All the patients registered their
complaints, measured body temperature with fixation of maximal
value. The diagnosis of the recurrence was made with control cystoscopy
carried out each 3 months in the first postoperative year and
later once in 6 months. RESULTS: Recurrent tumors were observed
in 25 (49%) and 7 (63.6%) patients of groups 1 and 2, respectively.
Side effects (high body temperature, dysuria and macrohematuria)
were reported in group 1 during basic treatment. Side effects
occurred also in maintenance. They were more pronounced than in
group 2. CONCLUSION: Intravesical BCG-therapy causes cystitis
considered a normal reaction to treatment. Fever indicates an
inflammatory reaction which is rather a positive sign of immune
reaction and may serve a prognostic factor.

Intravesical pH: a potentially important variable
affecting efficacy and the further development of anthracycline
chemotherapy for superficial bladder cancer.
Harris NM, Duffy PM, Crook TJ, Anderson WR, Sharpe P, Hayes MC,
Cooper AJ, Solomon LZ.
Solent Department of Urology, St. Mary's Hospital, Portsmouth,
UK. neilandjane@supanet.com
OBJECTIVE: To assess, using epirubicin-sensitive and multidrug
resistant (MDR) derivatives of human bladder cancer cell lines
in vitro, the probable effect of intravesical pH changes, with
and without the MDR antagonist verapamil, on the uptake, intracellular
distribution and cytotoxicity of epirubicin during intravesical
chemotherapy. MATERIALS AND METHODS: Incubations for cytotoxicity
testing were carried out in buffered medium containing epirubicin,
at pH values of 6.0-8.5, with verapamil where appropriate. The
cytotoxicity of epirubicin, with and without verapamil, was determined
using the tetrazolium cytotoxicity assay. Intracellular epirubicin
fluorescence was assessed using flow cytometry and confocal microscopy.
Flow cytometric total intracellular epirubicin fluorescence was
measured at pH 6.0, 6.4, 6.8, 7.2, and 7.6, and confocal microscopy
was carried out at pH 6.0 and 8.0. The MDR-reversing agent verapamil
was added at 100 micro g/mL to some incubations. RESULTS: Epirubicin
cytotoxicity in resistant cell lines appears considerably enhanced
by adding verapamil and further improved, especially in MDR cells,
by alkalinization of the drug solution to pH 8.0. Flow cytometry
results showed striking and consistent differences in epirubicin
handling with pH. Sensitive cells can be induced to absorb considerably
more drug at alkaline pH, whilst resistant cells show no such
behaviour. Nuclear drug fluorescence was greater in sensitive
cells at alkaline pH, but cytoplasmic drug fluorescence in the
resistant cells was little changed by pH. Adding verapamil to
resistant cells restored the sensitive phenotype of drug handling.
CONCLUSION: Buffering epirubicin to an alkaline pH before intravesical
application should increase its intrinsic cytotoxicity. The potential
for synergy at certain drug combinations will be enhanced by applying
these findings. MDR reversal and fatty acid augmentation of drug
uptake are discussed as examples.

A phase I study of intravesical suramin for the
treatment of superficial transitional cell
carcinoma of the bladder.
Uchio EM, Linehan WM, Figg WD, Walther MM.
Urologic Oncology Therapeutic Branch, Center for Cancer Research,
National Cancer Institute/NIH, Bethesda, MD, USA.
PURPOSE: Suramin is a polysulfonated naphthylurea that inhibits
proliferation and DNA synthesis of transitional cell carcinoma
cell lines. Its large molecular size and negative charge inhibit
bladder absorption, making suramin an excellent candidate for
intravesical chemotherapy. Intravesical suramin was evaluated
in a phase I study to define dose limiting toxicity and systemic
absorption, determine a starting dose and regimen for phase II
studies and provide a preliminary assessment of in vivo antitumor
activity. MATERIALS AND METHODS: Intravesical suramin treatment
was administered in 9 patients with histologically identified
transitional cell carcinoma (Tcis, Ta or T1) in whom at least
1 course of standard intravesical chemotherapy (bacillus Calmette-Guerin,
thiotepa or mitomycin C) had failed. Suramin was administered
once weekly for 6 weeks. Patients were treated in groups of 3
using a 60 cc volume and intrapatient dose escalation schedule.
Suramin doses of 0.3 to 614.4 mg./ml. were administered intravesically.
The last group was treated with the same weekly dose for 6 weeks.
RESULTS: The 9 patients underwent 54 treatments with suramin.
Plasma suramin concentration after treatment was 1.9 to 38.0 microg./ml.
and was not related to treatment dose. The dose escalation phase
was limited by the solubility of suramin in solution. Complications
included self-limited bladder spasms (less than 24 hours) in 4
of 54 treatments (7%) and new or worsening vesicoureteral reflux
in 3 ureters (17%). Another patient who was treated after the
Foley balloon was inflated in the urethra experienced bladder
spasms, skin flushing and fever (39C). Mean bladder capacity before
and after treatment was 600 and 540 ml., respectively. At followup
7 patients had stage Ta tumors and 2 had carcinoma in situ. CONCLUSIONS:
An intravesical suramin dose of 153 mg./ml was defined as a safe
treatment parameter with acceptable plasma concentrations and
minimal side effects. Phase II studies are needed to assess the
antitumor activity of suramin in patients with transitional cell
carcinoma of the bladder.

PURPOSE: The impact of orthotopic urinary diversion on the
quality of cystectomy and ensuing cancer control has not been
adequately studied. We analyzed our experience with this clinical
problem. MATERIALS AND METHODS: The records of 214 patients who
underwent cystectomy and orthotopic diversion for bladder cancer
were retrospectively evaluated and compared with those of 269
treated with an ileal conduit. Analyzed end points included overall
and cancer specific survival. We specifically assessed the patterns
of relapse and their association with pathological findings at
cystectomy in the neobladder group. RESULTS: No cancer specific
survival difference was identified in the neobladder and ileal
conduit cohorts when adjusting for pathological stage. Patterns
of relapse in 62 of the 214 patients with a neobladder (29%) included
local recurrence in 23 (11%), distant recurrence in 19 (9%), and
combined local and distant recurrence in 18 (8%). Urethral recurrence
was rare (2%). Of 10 patients (4.6%) diagnosed with upper tract
recurrence 6 and 4 initially had relapse in the ureteroenteric
anastomosis and renal pelvis, respectively. Five of the 6 patients
with anastomotic relapse had evidence of disease in the intramural
or juxtavesical ureter that was removed en bloc with the cystectomy
specimen. Only 1 patient required neobladder takedown after such
anastomotic recurrence. CONCLUSIONS: These results indicate that
neobladders do not compromise the quality of preceding cystectomy
or interfere with management in the presence of local or distant
disease relapse. Our data suggest that involvement of the intramural
or juxtavesical ureteral segment at cystectomy irrespective of
surgical margin status may identify patients at higher risk for
anastomotic recurrence, which is associated with an ominous prognosis.

This prospective, randomized study based on two associated
trials was designed to evaluate the effect of neoadjuvant chemotherapy
with cisplatin and methotrexate with folinic acid rescue or no
chemotherapy prior to local treatment in patients with T2-T4b,
NX-3, MO transitional cell carcinoma of the bladder. In the first
trial, local treatment consisted of cystectomy (DAVECA 8901) and
in the other trial the treatment was radiotherapy (DAVECA 8902);
153 eligible patients were randomized. The majority of the patients
(89%) completed the protocol. The overall time to progression
for all 153 patients was 12.9 months. Median time to progression
was 14.2 months with chemotherapy and 11.4 months without chemotherapy.
The actuarial 5-year overall survival rate for all 153 patients
was 29%, and 29% for both treatment groups. Multivariate analyses
showed that T-stage, tumour size and serum creatinine were independent
prognostic factors for survival. The cystectomy trial included
33 patients. Median survival was 78.9 months, 82.5 months with
chemotherapy and 45.8 months without chemotherapy (p = 0.76).
The radiotherapy trial included 120 patients. The median survival
was 17.6 months. Median survival was 19.2 months in the group
receiving chemotherapy and 16.3 in the group not receiving chemotherapy.
The 5-year survival rate was 19% in the group receiving chemotherapy
and 24% in the groups not receiving chemotherapy (p = 0.98). Late
toxicity grade 3 or 4 of the bladder was recorded in 25% of the
patients (actuarial rate). Neoadjuvant chemotherapy with cisplatin
and methotrexate did not significantly improve disease-free or
overall survival in 153 randomized patients with invasive bladder
cancer.

PURPOSE: We assessed the efficacy and safety of adoptive immunotherapy
administered to 17 patients with TaGIII or recurrent TaGII superficial
bladder cancer following transurethral tumor resection. MATERIALS
AND METHODS: Macrophage activated killer (MAK) cells were obtained
from autologous mononuclear cells harvested by apheresis, after
in vitro culture for 7 days and activation with interferon-gamma
on the last day of culture. The patients received 6 weekly intravesical
infusions of approximately 2 x 10(8) cells each. Additionally,
5 patients received 2 or 3 more infusions at 3-month intervals.
Each patient was followed for 1 year or until tumor recurrence,
whichever came first. RESULTS: A total of 112 intravesical infusions
were performed. During the 12-month followup period 8 patients
experienced 11 common toxicity criteria grade 1 or grade 2 adverse
events considered possibly related to protocol. No clinically
relevant grade 1 or 2 laboratory test results were reported while
the patients received treatment. In 17 patients 8 tumors recurred
compared to 34 recurrences during the year before the first MAK
cell infusion. This difference was highly significant (p </=0.0005).
CONCLUSIONS: The promising efficacy and safety results of this
study and the fact that the MAK cell treatment regimen proved
feasible should encourage initiation of further large scale studies
to confirm these data.

Impact of a second transurethral resection on
the staging of T1 bladder cancer.
Dalbagni G, Herr HW, Reuter VE.
Department of Urology, Memorial Sloan-Kettering Cancer Center,
New York, New York 10021, USA.
OBJECTIVES: To evaluate the impact of a second transurethral
resection (TUR) on the pathologic stage in a unique patient population
with T1 tumors. METHODS: Seventy-one patients with Stage T1 transitional
cell carcinoma of the bladder were prospectively enrolled and
underwent restaging TUR. Fifteen patients underwent immediate
cystectomy and 56 patients were treated endoscopically. The patients
who underwent immediate cystectomy were the subjects of this report.
RESULTS: Fifteen patients underwent immediate cystectomy. At restaging
TUR, 13 patients had persistent T1, 1 patient had Tis, and 1 patient
had no residual disease. The pathologic stage at cystectomy revealed
the presence of residual disease in 12 of 15 patients, and 3 patients
had pT0. Of the 12 patients with residual disease, 3 had residual
pT1, 2 had pT1 with pTis, 5 had pTis alone, and 2 had muscle-invasive
tumors. Thirteen percent of the patients who underwent immediate
cystectomy after restaging TUR had a pathologic stage greater
than pT1. CONCLUSIONS: Understaging for T1 disease is negligible
after restaging TUR.

[Prospective study of effectiveness. Reoperation
(re-TUR) in superficial bladder carcinoma]
[Article in German]

To assess the rate of residual cancer after transurethral resection
(TUR) of superficial bladder cancer, a prospective study was carried
out. All patients with transitional cell cancer (TCC) stage pTa-pT1
underwent a repeat TUR (ReTUR) within 6-8 weeks. Sites and rates
of tumors found during ReTUR were documented as well as the morbidity
of the ReTUR. Of a total of 192 TUR, superficial TCC was found
in 124 cases; 83 underwent ReTUR according to the study protocol.
Residual tumor was detected in 27% of pTa and 53% of pT1 tumors.
Worsening of grading or T stage was found in 8%. Of the tumors
detected by ReTUR, 81% were localized at the site of the first
TUR. In this prospective study, residual tumor formation was detected
in a high percentage. Routine ReTUR is therefore recommended in
superficial bladder cancer except solitary pTaGI lesions.
