Long-term oncologic data on patients undergoing robot-assisted radical cystectomy (RARC) for non-metastatic bladder cancer (BCa) are limited. The purpose of this study is to describe long-term oncologic outcomes of patients receiving robotic radical cystectomy at a high-volume European Institution. We analyzed data of 107 patients treated with RARC between 2003 and 2012 at a high-volume robotic center. Clinical, pathologic, and survival data at the latest follow-up were collected. Clinical recurrence (CR)-free survival, cancer-specific mortality (CSM)-free survival, and overall survival (OS) were plotted using Kaplan-Meier survival curves. Cox proportional hazard models investigated predictors of CR and CSM. Competing-risk regressions were utilized to depict cumulative incidences of death from BCa and death from other causes after RARC at long term. Pathologic nonorgan-confined BCa was found in 40% of patients, and 7 (7%) patients had positive soft tissue surgical margins.

Cox proportional hazard models investigated predictors of CR and CSM. Competing-risk regressions were utilized to depict cumulative incidences of death from BCa and death from other causes after RARC at long term. Pathologic nonorgan-confined BCa was found in 40% of patients, and 7 (7%) patients had positive soft tissue surgical margins. Median (interquartile range [IQR]) number of nodes removed was 11 (6, 14), and 26% of patients had pN + disease. Median (IQR) follow-up for survivors was 123 (117, 149) months. The 12-year CR-free, CSM-free and overall survival were 55% (95% confidence interval [CI] 44%, 65%), 62% (95% CI 50%, 72%), and 34% (95% CI 24%, 44%), respectively. Nodal involvement on final pathology was associated with poor prognosis on multivariable competing risk analysis. The cumulative incidence of non-cancer death exceeded that of death from BCa after approximately ten years after RARC. We provided relevant data on oncologic outcomes of RARC at a high-volume robotic center, with acceptable rates of clinical recurrence and cancer-specific survival at long-term. In patients treated with RARC, the cumulative incidence of death from causes other than BCa is non-negligible, and should be taken into consideration for post-operative follow-up.Show less
