Abstract
Background and Purpose:
The aim of our study was to assess the oncologic outcomes of robot-assisted radical cystectomy (RARC) in patients with bladder cancer (BCa) treated in a high-volume robotic center.
Materials and Methods:
We retrospectively collected data of 155 consecutive patients who received RARC for urothelial BCa from January 2004 to May 2014. Kaplan–Meier analyses were used to assess time to recurrence, cancer-specific mortality (CSM) rate, and overall mortality rate. Uni- and multivariable Cox regression models addressed the predictors of recurrence and CSM.
Results:
Median follow-up for survivors was 42 months. Overall, 43%, 34%, 55%, and 18% of the patients had pT ≤1, pT2, pT3/4, and pN1–3 disease, respectively. Overall, 76% of the patients had high-grade disease at final pathology. The positive surgical margin rate was 9%. The 5-year recurrence-free, CSM-free, and overall survival estimates were 53.7%, 73.5%, and 65.2%, respectively. Among patients who experienced recurrence, 12.0%, 4.0%, and 84.0% had local, peritoneal, and distant recurrence, respectively. In multivariable Cox regression analyses, pathologic stage and nodal status represented independent predictors of recurrence and CSM (all p ≤ 0.04).
Conclusions:
In a high-volume robotic center, RARC provides acceptable oncologic outcomes in patients with urothelial BCa. Tumor stage and nodal status represent independent predictors of recurrence and CSM in this setting.
