Radical cystectomy for bladder cancer after definitive prostate cancer treatment

Mortality rates in radical cystectomy patients with bladder cancer after radiation therapy for prostate cancer

OBJECTIVE

To conduct a population-based study examining cancer-specific mortality (CSM) and other-cause mortality (OCM) differences in patients with radiation-induced secondary bladder cancer (RT-BCa) vs those with primary bladder cancer (pBCa) undergoing radical cystectomy (RC).

METHODS

Within the Surveillance, Epidemiology, and End Results database (2004-2020), we identified patients with T2-4N0-3M0 bladder cancer treated with RC, who had previously been treated with external beam radiation therapy (EBRT) or brachytherapy for prostate cancer, as well as patients with T2-4N0-3M0 pBCa treated with RC. Cumulative incidence plots and multivariable competing risks regression (CRR) models were used to assess CSM after additional adjustment for OCM. The same methodology was then repeated based on organ-confined (OC: T2N0M0) and non-organ-confined (NOC: T3-4 and/or N1-3) disease.

RESULTS

Of 9957 RC patients, RT-BCa was identified in 347 (3%) compared with 9610 (97%) who had pBCa. In multivariable CRR models, no CSM differences were recorded in the overall comparison (P = 0.8), nor in sub-groups based on OC and NOC disease (P = 0.8 and 0.7, respectively). Conversely, multivariable CRR models identified RT-BCa as an independent predictor of 1.3-fold higher OCM in the overall cohort and of 1.5-fold higher OCM in those with NOC disease. In a sensitivity analysis of patients with NOC disease, EBRT was associated with higher OCM rates (hazard ratio 1.5). By contrast, OCM rates were not different in those with OC disease (P = 0.8).

CONCLUSION

Our study showed that RC for RT-BCa was associated with similar CSM rates as RC for pBCa, regardless of disease stage. However, patients who had undergone EBRT exhibited significantly higher OCM in the NOC sub-group.

Incidence, Characteristics and Survival Rates of Bladder Cancer after Rectosigmoid Cancer Radiation

BACKGROUND

Historical external beam radiation therapy (EBRT) for rectosigmoid cancer (RCa) predisposed patients to an increased risk of secondary bladder cancer (BCa). However, no contemporary radiotherapy studies are available. We addressed this knowledge gap.

MATERIALS AND METHODS

Within the Surveillance, Epidemiology, and End Results database (2000-2020), we identified non-metastatic RCa patients who either underwent radiotherapy (EBRT+) or did not (EBRT-). Cumulative incidence plots and multivariable competing risk regression models (CRR) were fitted to address rates of BCa after RCa. In the subgroup of BCa patients, the same methodology addressed BCa-specific mortality (BCSM) according to EBRT exposure status.

RESULTS

Of the 188,658 non-metastatic RCa patients, 54,562 (29%) were EBRT+ vs. 134,096 (73%) who were EBRT-. In the cumulative incidence plots, the ten-year BCa rates were 0.7% in EBRT+ vs. 0.7% in EBRT- patients (p = 0.8). In the CRR, EBRT+ status was unrelated to BCa rates (multivariable HR: 1.1, p = 0.8). In the subgroup of 1416 patients with BCa after RCa, 443 (31%) were EBRT+ vs. 973 (69%) who were EBRT-. In the cumulative incidence plots, the ten-year BCSM rates were 10.6% in EBRT+ vs. 12.1% in EBRT- patients (p = 0.7). In the CRR, EBRT+ status was unrelated to subsequent BCSM rates (multivariable HR: 0.9, p = 0.9).

CONCLUSION

Although historical EBRT for RCa predisposed patients to higher BCa rates, contemporary EBRT for RCa is not associated with increased subsequent BCa risk. Moreover, in patients with BCa after RCa, exposure to EBRT does not affect BCSM.

Radical cystectomy in bladder cancer patients previously treated for prostate cancer: Insights from a large European multicentric series

INTRODUCTION

Previous radical prostatectomy (RP) for prostate cancer (PCa) might impair feasibility of radical cystectomy (RC) for bladder cancer (BCa). The current study addressed morbidity, operative time (OT), and length of stay (LOS) of RC, within the largest available series of patients with history of previous RP.

MATERIALS AND METHODS

All patients previously submitted to RP for PCa and subsequently submitted to RC for BCa, at six high-volume European institutions between 2010 and 2019, were identified. Presence of either PCa or BCa metastases, RT as primary treatment for PCa, and palliative RC represented exclusion criteria. The quality criteria for accurate and comprehensive reporting of intra- and post-operative surgical outcomes, recommended by the European Association of Urology guidelines, were fulfilled. Multivariable logistic and Poisson regression analyses were performed.

RESULTS

Overall, 140 RC patients with history of RP were identified. After RP, 69 (49%) patients received radiotherapy (RT) for PCa, either in adjuvant (n = 50, 36%) or salvage setting (n = 19, 13%). Median age-adjusted Charlson comorbidity index was 6 (IQR 5, 7). Median OT, estimated blood loss and LOS were, respectively, 300 min, 500 ml, and 16 days. Intra-operative transfusions rate was 47% (n = 65). One intra-operative complication occurred (EAUiaiC grade 2, perforation of the rectum managed with immediate repair). Eighty-two (59%) patients experienced a total of 107 post-operative complications during the hospital stay, and seven (5%) patients required hospital readmission. In multivariable regression analyses, RT for PCa was associated with higher risk of post-operative complications (odds ratio 1.82, p = 0.039), longer OT (incidence rate ratio 1.09, p < 0.001), and longer LOS (incidence rate ratio 1.24, p < 0.001).

CONCLUSIONS

RC in patients with history of RP is feasible, albeit burdened by remarkable morbidity, even in centers of excellence. RT after RP for PCa portends worse surgical outcomes.

Robotic Radical Cystectomy Outcomes after Intervention for Prostate Cancer

Introduction and Objectives: We evaluated patients who underwent treatment for prostate cancer and then subsequent robot-assisted radical cystectomy (RARC). Our objective was to understand clinical, pathologic, and survival outcomes in these patients. Materials and Methods: A total of 333 male patients underwent RARC with standard intracorporeal urinary diversion from 2009 to 2019. We evaluated patients who underwent a radical prostatectomy (RP) and either external beam radiation or brachytherapy (XRT) before RARC. These patients were compared with patients who underwent RARC without any prior intervention for or history of prostate cancer (radical cystectomy [RC]). Results: Patients in the RP and XRT groups were found to be older than the RC group (p = 0.0108) and also have a greater Charlson comorbidity index (p < 0.001). There was no difference in estimated blood loss, operative time, and length of stay across all three groups. The RP group had a higher rate of positive margins 31.58% compared with RC and XRT at 8.22% and 10.00%, respectively (p = 0.0036). There was also a higher rate of extravesical disease on final pathology report for the XRT group at 60.00% compared with 37.5% and 36.85% for RC and RP, respectively (p = 0.0056). Overall survival was lowest in the XRT group compared with RP and RC (p > 0.001) with no difference in recurrence-free survival. Conclusion: Patients in the RP group have higher rates of positive margin, whereas patients in the XRT group have higher rates of extravesical disease and overall survival after undergoing a RARC. Careful counseling and attention to these parameters is required in these patient populations.

The Impact of Previous Prostate Surgery on Surgical Outcomes for Patients Treated with Robot-assisted Radical Cystectomy for Bladder Cancer

BACKGROUND

The feasibility and safety of robot-assisted radical cystectomy (RARC) may be undermined by unfavorable preoperative surgical characteristics such as previous prostate surgery (PPS).

OBJECTIVE

To compare perioperative outcomes for patients undergoing RARC with versus without a history of PPS.

DESIGN, SETTING, AND PARTICIPANTS

The study included 220 consecutive patients treated with RARC and pelvic lymph node dissection for bladder cancer at a single European tertiary centre. Of these, 43 had previously undergone PPS, defined as transurethral resection of the prostate/holmium laser enucleation of the prostate (n=21) or robot-assisted radical prostatectomy (n=22).

SURGICAL PROCEDURE

RARC in patients with a history of PPS.

MEASUREMENTS

Data on postoperative complications were collected according to the quality criteria for accurate and comprehensive reporting of surgical outcomes recommended by the European Association of Urology guidelines. Multivariable logistic, linear, and Poisson regression analyses were performed to test the effect of PPS on surgical outcomes.

RESULTS AND LIMITATIONS

Overall, 43 patients (20%) were treated with RARC after PPS. Operative time (OT) was longer in the PPS group (360 vs 330min; p<0.001). Patients with PPS experienced higher rates of intraoperative complications (19% vs 6.8%) and higher rates of 30-d (67% vs 39%), and Clavien-Dindo >3 (33% vs 16%) postoperative complications (all p<0.05). Moreover, the positive surgical margin (PSM) rate after RARC was higher in the PPS group (14% vs 4%; p=0.03). On multivariable analyses, PPS at RARC independently predicted higher risk of intraoperative (odds ratio [OR] 2.10, 95% confidence interval [CI] 1.04-6.21; p=0.01) and 30-d complications (OR 2.26, 95% CI 1.05-5.22; p=0.02), as well as longer OT (relative risk [RR] 1.03, 95% CI 1.00-1.05; p=0.02) and length of stay (RR 1.13, 95% CI 1.02-1.26; p=0.02). Lack of randomization represents the main limitation.

CONCLUSIONS

RARC in patients with a history of PPS is feasible, but it is associated with a higher risk of complications and longer OT and length of stay. Moreover, higher PSM rates have been reported for these patients. Thus, measures aimed at improving surgical outcomes appear to be warranted.

PATIENT SUMMARY

We investigated the effect of previous prostate surgery (PPS) on surgical outcomes after robot-assisted removal of the bladder. We found that patients with PPS have a higher risk of complications and longer hospitalization after bladder removal. These patients deserve closer evaluation before this type of bladder operation.

The Prognostic Value of Previous Irradiation on Survival of Bladder Cancer Patients

Background: Radiation exposure is an established risk factor for bladder cancer, however consensus is lacking on the survival characteristics of bladder cancer patients with a history of radiation therapy (RT). Confounding patient comorbidities and baseline characteristics hinders prior attempts at developing such a consensus.

Objective: To compare the survival characteristics of patients with suspected radiation-induced second primary cancer (RISPC) of the bladder to those with de novo bladder cancer, taking into account the patient comorbidities and baseline characteristics predictive of survival.

Methods: Retrospective analysis of patients with muscle-invasive (≥T2a) or BCG-refractory stage Tis-T1 urothelial bladder cancer. Patients were excluded if prior RT exposure was used as treatment for bladder cancer or if cause of death was due to post-operative complications. A digit matching propensity score algorithm was used to match patients with prior radiation treatment to those without prior treatment. Cox regression analysis for time until death was performed following creation of the propensity score matched sample.

Results: 29 patients with history of RT were matched with two controls each, resulting in a dataset of 87 observations in the event model. Results from the Cox model indicate a significantly increased hazard ratio for death at 2.22 (p = 0.047, 95% CI: 1.015–4.860) given a history of prior radiation therapy.

Conclusions: In a small cohort, bladder cancer patients who underwent cystectomy had a significantly higher risk of death in the face of prior pelvic RT. This effect was found to be independent of surgical complications, numerous established patient characteristics and comorbidities traditionally predictive of survival.

Radical cystectomy and ileal orthotopic bladder substitution after radical retropubic prostatectomy: functional and oncological results

Men with good functional results following radical retropubic prostatectomy (RRP) and requiring radical cystectomy (RC) for subsequent bladder carcinoma seldom receive orthotopic bladder substitution. Four patients aged 62-72 years (median 67 years), who had undergone RRP for prostate cancer of stage pT2bN0M0 Gleason score 6 (n = 1), pT2cN0M0 Gleason score 5 and 6 (n = 2) and pT3bN0M0 Gleason score 7 (n = 1) 27 to 104 months before, developed urothelial bladder carcinoma treated with RC and ileal orthotopic bladder substitution. After radical prostatectomy three were continent and one had grade I stress incontinence, and three achieved intercourse with intracavernous alprostadil injections. Follow-up after RC ranged between 27 and 42 months (median 29 months). At the 24-month follow-up visit after RC daily urinary continence was total (0 pad) in one patient, two used one pad for mild leakage, and one was incontinent following endoscopic incision of anastomotic stricture. One patient died of progression of bladder carcinoma, while the other three are alive without evidence of disease. The three surviving patients continued to have sexual intercourse with intracavernous alprostadil injections. Men with previous RRP have a reasonable chance of maintaining a satisfactory functional outcome following RC and ileal orthotopic bladder substitution.

Radical Cystectomy after BCG Immunotherapy for High-Risk Nonmuscle-Invasive Bladder Cancer in Patients with Previous Prostate Radiotherapy

Purpose. Intravesical Bacillus Calmette-Guerin (BCG) immunotherapy is indicated for high-grade nonmuscle-invasive bladder cancer (NMIBC). The efficacy of BCG in patients with a history of previous pelvic radiotherapy (RT) may be diminished. We evaluated the outcomes of radical cystectomy for BCG-treated recurrent bladder cancer in patients with a history of RT for prostate cancer (PC). Methods. A retrospective chart review was performed to identify patients with primary NMIBC. We compared the outcomes of three groups of patients who underwent radical cystectomy for BCG-refractory NMIBC: those with a history of RT for PC, those who previously underwent radical prostatectomy (RP), and a cohort without PC or RT exposure. Results. From 1996 to 2008, 53 patients underwent radical cystectomy for recurrent NMIBC despite BCG. Those with previous pelvic RT were more likely to have a higher pathologic stage and decreased recurrence-free survival compared to the groups without prior RT exposure. Conclusion. Response rates for intravesical BCG therapy may be impaired in those with prior prostate radiotherapy. Patients with a history of RT who undergo radical cystectomy after failed BCG are more likely to be pathologically upstaged and have decreased recurrence-free survival. Earlier consideration of radical cystectomy may be warranted for those with NMIBC who previously received RT for PC.

Secondary malignancies following radiotherapy for prostate cancer

Human exposure to sources of radiation as well as the use of radiation-derived therapeutic and diagnostic modalities for medical reasons has been ongoing for the last 60 years or so. The carcinogenetic effect of radiation either due to accidental exposure or use of radiation for the treatment of cancer has been undoubtedly proven during the last decades. The role of radiation therapy in the treatment of patients with prostate cancer is constantly increasing as less-invasive treatment modalities are sought for the management of this widely, prevalent disease. Moreover the wide adoption of screening for prostate cancer has led to a decrease in the average age that patients are diagnosed with prostate cancer. Screening has also resulted in the diagnosis of low-grade, less-aggressive prostate cancers which would probably never lead to complications or death from the disease. Radiotherapy for prostate cancer has been linked to the late occurrence of second malignancies both in the true pelvis and outside the targeted area due to low-dose radiation scatter. Secondary malignancies following prostate irradiation include predominantly bladder cancer and, to a lesser extent, colon cancer. Those secondary radiation-induced bladder tumors are usually aggressive and sometimes lethal. Care should be given to the long-term follow up of patients under radiation therapy for prostate cancer, while the indications for its use in certain cases should be reconsidered.

Intravesical bacillus Calmette-Guerin immunotherapy after previous prostate radiotherapy for high-grade non-muscle-invasive bladder cancer

OBJECTIVES

Intravesical bacillus Calmette-Guerin (BCG) immunotherapy is a standard treatment for high-grade non-muscle-invasive bladder cancer (NMIBC). We evaluated outcomes of BCG therapy for NMIBC in patients with a previous history of prostate cancer (CaP) radiotherapy (RT).

MATERIALS AND METHODS

A retrospective review of patients with a history of CaP RT who subsequently underwent treatment with intravesical BCG for high-grade NMIBC was performed. Patients were categorized as "BCG success" or "BCG failure" (defined as stage progression or recurrent/persistent disease). We evaluated factors related to the radiotherapy (type, interval to BCG), bladder cancer (clinical stage, immunotherapy type, and course), and patient comorbidities, to identify factors associated with BCG failure.

RESULTS

From 1996 to 2008, 26 patients with high-grade NMIBC received intravesical BCG immunotherapy after CaP RT. At a mean follow-up of nearly 5 years, 13 patients (50%) were successfully managed with one or more induction courses of BCG with or without the addition of interferon alpha. Twelve (46%) eventually required cystectomy for disease recurrence or progression, of which half had pathologically advanced disease (≥pT3). Clinical stage was similar between BCG success and failure patients (P = 0.40). Those who failed immunotherapy were more likely to have had a longer interval between RT and BCG induction (5.8 vs. 2.4 years, P = 0.02).

CONCLUSION

Approximately 50% of patients with NMIBC who were previously exposed to prostate radiation had a durable response to intravesical BCG. For non-responders, extravesical progression was common.

Radical cystectomy in patients previously treated for localized prostate cancer

OBJECTIVES

To present outcomes of a contemporary series of patients undergoing radical cystectomy (RC) for bladder cancer after previous treatment for localized cancer of the prostate (CaP).

METHODS

A retrospective review of more than 1000 RCs performed for bladder cancer between 1995 and 2008 identified 49 patients previously treated for localized CaP. Patients were stratified according to the type of primary therapy received for CaP: any form of primary or adjuvant radiotherapy (brachytherapy or external beam radiotherapy) versus radical prostatectomy (RP) monotherapy. Perioperative data were analyzed and compared between the 2 groups.

RESULTS

Of 49 patients, 40 (82%) underwent primary or adjuvant radiotherapy and 9 (18%) RP alone. Eleven (22%) patients received a continent diversion. Mean estimated blood loss (EBL) and hospital stay were 979 mL and 12 days, respectively. Extravesical disease (≥pT3a) was present in 23 patients (57.5%) in the radiotherapy group and in 2 patients (22%) in the RP group. Ten patients (all in the radiotherapy group) had a positive margin, 9 (90%) of whom had pathologic T4 disease. The overall major perioperative complication rate was 41%. Of the 6 patients with an ONB (all after RP), 4 had severe incontinence.

CONCLUSIONS

Patients undergoing RC after previous treatment for localized CaP are at increased risk for perioperative morbidity. Patients should be counseled that orthotopic diversion after RP may be associated with significant incontinence. Extravesical disease is more prevalent in patients treated with previous radiation. We observed a high rate of positive margins associated with pathologic T4 disease in this cohort.

Impact of previous radiotherapy for prostate cancer on clinical outcomes of patients with bladder cancer

PURPOSE

The impact of prostate cancer radiotherapy on the biological behavior of bladder cancer remains unclear. We compared the outcomes of patients with bladder cancer previously treated for prostate cancer with radiotherapy vs other treatment modalities.

MATERIALS AND METHODS

We identified 144 patients diagnosed with bladder cancer between January 1992 and June 2007 with a previous prostate cancer diagnosis. Clinicopathological data and outcomes were compared between patients with irradiated (brachytherapy and/or external beam radiation therapy 83) and nonirradiated (androgen deprivation therapy, radical prostatectomy and/or surveillance 61) disease.

RESULTS

Median time between prostate and bladder cancer diagnoses was longer in the irradiated vs nonirradiated group (59 months, IQR 25 to 88, vs 24 months, IQR 2 to 87, p = 0.007). Patients in the irradiated group presented with higher tumor grade (high 92% vs 77%, p = 0.016) and had progression to higher stage disease (muscle invasive 70% vs 43%, p = 0.001) than those in the nonirradiated group. Of the patients undergoing cystectomy those previously treated with radiation had a numerically higher rate of nonorgan confined disease (75% vs 56% for nonirradiated, p = 0.1). Among all patients with bladder cancer 5-year cancer specific survival was 73% (95% CI 59-87) for irradiated vs 83% (95% CI 71-95) for nonirradiated (p = 0.07). Median followup was 53 months (IQR 24 to 75).

CONCLUSIONS

More time elapsed between prostate and bladder cancer diagnoses for patients treated with radiation, and these patients also presented with more advanced disease. Future studies are needed to further establish clinical differences in bladder cancer between irradiated and nonirradiated cases, and whether biological differences exist.

Bladder cancer after radiotherapy for prostate cancer: detailed analysis of pathological features and outcome after radical cystectomy

PURPOSE

We reviewed outcomes and features in patients with bladder cancer who underwent cystectomy and had a history of radiation for prostate cancer.

MATERIALS AND METHODS

We performed a retrospective analysis of the University of Miami cystectomy database and identified 34 patients with a history of radiotherapy for prostate cancer. An age and stage matched control group was used to compare survival. Our entire male cystectomy population was used to compare clinicopathological features.

RESULTS

Mean age in the 34 patients with cystectomy was 75 years with a mean latency of 5 years from prostate cancer radiation. Radiotherapy was the primary treatment modality for prostate cancer in 32 of 34 patients and 2 received adjuvant radiation. Of the patients 86% received external beam radiation. Hematuria was the initial symptom in 86% of the cases. In 53% of the patients the initial diagnosis was muscle invasive bladder cancer. An ileal conduit was the method of urinary diversion in 33 cases. Major perioperative complications developed in 9% of the patients. There was 1 perioperative death, resulting in a mortality rate of 2.9%. Of the patients 54% presented with a locally advanced (pT3-4) tumor. Patients with a history of radiation therapy for prostate cancer had significantly poorer overall and bladder cancer specific survival than the matched control group.

CONCLUSIONS

Most bladder cancers in patients with a history of radiation for prostate cancer present as locally advanced tumors and patients have poorer survival than age and stage matched controls.

Muscle-Invasive Urothelial Carcinoma of the Bladder

Muscle-invasive urothelial (transitional cell) carcinoma is a potentially lethal condition for which an attempt at curative surgery is required. Clinical staging does not allow for accurate determination of eventual pathologic status. Muscle-invasive urothelial carcinoma is a highly progressive disease, and initiation of definitive therapy within 3 months of diagnosis is worthwhile. Age is not a contraindication for aggressive surgical care, and surgical candidates should be evaluated in the context of overall medical comorbidity. In those patients who undergo surgery, clinical pathways may streamline care. Radical cystectomy remains the "gold standard" of therapy, providing 5-year survival rates of 75% to 80% in patients with organ-confined disease, yet organ-sparing procedures demonstrate clinical effectiveness as well. Cystectomy should be undertaken with the intent of performing complete pelvic lymph node dissection and attaining surgically negative margins. In younger female patients, the preservation of reproductive organs may be achieved in many cases. Prostate- and seminal vesicle-preserving cystectomy has been performed, yet the long-term safety and efficacy of such a procedure remains to be determined. Laparoscopic and robotic cystectomy procedures continue to be explored by several investigators. The role of "radical transurethral resection" in muscle-invasive disease is limited to a small cohort of patients, and, when it is performed, cystectomy may be required to consolidate therapy. Postoperative follow-up after cystectomy should occur over short intervals during the first 2 years and can be extended, but not discontinued, beyond that time. Currently, no tumor markers have been prospectively validated to help guide clinical decision making, and prospective trials incorporating marker data should be encouraged.

Clinical characteristics of bladder cancer in patients previously treated with radiation for prostate cancer

OBJECTIVE

To determine if bladder cancer diagnosed after prostatic radiation therapy (RT) differs in behaviour from bladder cancer diagnosed after prostate cancer not treated with RT, as such bladder cancer is thought to be more aggressive than de novo bladder cancer, and epidemiological studies show a higher rate of bladder cancer in patients after irradiation.

PATIENTS AND METHODS

We reviewed our records to identify patients who had a diagnosis of bladder cancer with a previous diagnosis of prostate cancer. Patient age, date of diagnosis of prostate cancer, date of diagnosis of bladder cancer, symptoms, clinical stage, initial pathology, definitive therapy, definitive pathological stage, and disease status were recorded.

RESULTS

In all, 100 patients were identified who had a diagnosis of bladder cancer after a diagnosis of prostate cancer between January 1992 and August 2003; 58 had had RT for prostate cancer. The mean time between a diagnosis of bladder cancer and prostate cancer was 62 months in the RT group and 34 months in the unirradiated group (P = 0.002) At diagnosis of bladder cancer, 56 (97%) of the patients who received RT had high-grade urothelial carcinoma, vs 27 (64%) of those not irradiated (P < 0.001). Thirty (52%) of the patients with RT had muscle-invasive bladder cancer, vs 17 (40%) of those not irradiated (P = 0.3). The survival rate was similar for both groups.

CONCLUSIONS

Bladder cancer is diagnosed later, and is of higher grade, in patients who are irradiated for prostate cancer than in those treated with other methods. Patients with prostate cancer who are treated with RT should be monitored closely for the presence of bladder cancer.

Complications after cystectomy and urinary diversion in patients previously treated for localized prostate cancer

OBJECTIVES

To assess the morbidity associated with radical cystectomy in patients who had previously undergone definitive treatment of prostate cancer.

METHODS

A retrospective review was undertaken, identifying 35 patients undergoing radical cystectomy with a previous history of radical prostatectomy and/or radiotherapy for prostate cancer. The clinical and surgical information was analyzed to assess patient outcomes. Specific attention was given to the rate, severity, and time course of the postoperative complications. In addition, outcomes after orthotopic and continent cutaneous diversion in this patient cohort were examined.

RESULTS

An overall complication rate of 76% was seen in this patient cohort, with 47% of patients experiencing a complication that presented later than postoperative day 30. Radiotherapy was associated with a slightly greater complication rate compared with radical prostatectomy monotherapy (77% versus 71%). Continent urinary diversion (n = 14) was associated with increased morbidity compared with ileal conduit diversion (n = 21). However, a greater percentage of the complications occurring in patients undergoing ileal conduit diversion were major (80% versus 67%).

CONCLUSIONS

Our experience has suggested that radical cystectomy in patients previously treated for prostate cancer with radiotherapy and/or radical prostatectomy may be associated with a greater level of morbidity than previously reported. This finding may be, in part, because a significant portion of complications present in a delayed fashion and, as such, have not been seen in previous reports with limited follow-up. For this reason, careful consideration of these risks is necessary when counseling this patient cohort regarding the decision to undergo radical cystectomy.

Salvage cystectomy after failure of interstitial radiotherapy and external beam radiotherapy for bladder cancer

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.

Cystectomy with orthotopic reconstruction following radical retropubic prostatectomy

The development of infiltrative bladder carcinoma in patients previously treated with radical prostatectomy due to prostate adenocarcinoma represents a challenging perspective. Radical cystectomy remains the best option for invasive bladder cancer, however, there are few reports about the best approach to such individuals. Nevertheless, despite possible technical difficulties found during surgery, the orthotopic urinary shunt is a reasonable option in selected cases.
