Despite encouraging data deriving from colorectal surgery, evidences in favor to ERAS protocols following RARC are poor. Moreover, according to a recent survey of surgeons with a specialist interest in RC, the adherence to ERAS protocols is <20% [1]. Retrospective and preliminary data from the robotic consortium have supported oncologic effectiveness of RARC; however in the only prospective randomized trial comparing RARC and ORC urinary diversions were performed extracorporeally, potentially impairing the benefits of minimally invasive surgery [2]. Robot assisted radical cystectomy (RARC) has the aim of providing adequate cancer control while minimizing invasiveness of open radical cystectomy (ORC). The primary end-point of this trial is to demonstrate a reduction of perioperative transfusion rate in RARC arm by 50% compared to ORC arm. ERAS protocols may significantly contribute to shortening length of hospital stay, a key outcome in this clinical setting of patients receiving RC, being the mean length of hospital stay around 14 days in Italy. Investigators' hypothesis is that the reduced invasiveness of RARC might contribute to an increased adoption of ERAS protocols (reduced need for reinsertion of nasogastric tube, shorter time to first flatus, to mobilization, to regular diet and finally shorter duration of hospital stay). Assessment of oncologic outcomes of RARC, although not the primary endpoint of the present study, is certainly an outcome of interest. The expected duration of enrollment (18 mo) should provide 2-yr oncologic outcomes for about 66% of patients. Two-year recurrence free survival has been reported as a valid surrogate marker of long term oncologic survival after RC. Specific Aim 1:To demonstrate superiority of RARC versus ORC in terms of 50% reduction of perioperative transfusion rates. Specific Aim 2: To evaluate invasiveness of both surgical approaches by assessing the adherence to ERAS protocols in both and the incidence of perioperative and 30-d, 90d, 180d complications, readmission rates (30d, 90d). Cost analysis will assess the potential impact of shorter hospital stay on overall costs of robotic procedures. Specific Aim 3: To assess quality of life at 6-mo, 12-mo and 24-mo follow-up evaluation and to perform a matched comparison of oncologic and functional outcomes between two arms.
