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

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.
