Abstract

Objectives: To examine perioperative and oncologic outcomes of open (ORC) and robot-assisted radical cystectomy (RARC) in bladder cancer (BCa) patients. Methods and materials: 368 consecutive patients with cT1-4 MO BCa treated at two high-volume European centers between 2004 and 2013 were evaluated. Data on complications, operative time, blood loss, postoperative transfusion, reoperation, length of stay (LOS), positive margins, recurrence, cancer-specific mortality (CSM), and overall survival were evaluated. Uni- and multivariable regression analyses tested the impact of the surgical approach on perioperative and oncologic outcomes. Results: Overall, 230 (62.5%) and 138 (37.5%) patients were treated with ORC and RARC. In multivariable analyses RARC patients had higher odds of prolonged operative time and low-grade complications (all P <= 0.001). Patients treated with ORC had higher odds of blood loss >500 ml and prolonged LOS (all P <= 0.03). No differences were observed in high-grade complications and positive margins (all P >= 0.06). No differences were observed in 5-year recurrence-free and CSM-free survival rates between patients treated with ORC vs. RARC (57.1 vs. 54.2% and 61.9 vs. 73.5%;all P >= 0.3). This was confirmed in multivariable analyses, where the surgical approach was not associated with the risk of recurrence and CSM (all P >= 0.1). Conclusions: Although ORC might be associated with a shorter operative time, RARC led to lower blood loss and shorter LOS. No differences exist in high-grade complications and positive margins. RARC and ORC provide similar oncologic control. (C) 2016 Elsevier Ltd. All rights reserved.
