Background: Data on oncological follow-up after robotic-assisted radical cystectomy (RARC) have been reported only scarcely and individual studies have reported an increase in early recurrences and atypical recurrences. Patients and Methods: Clinical data of 89 patients with RARC were compared to 59 patients with open radical cystectomy (ORC) at a single institution. Two-year cancer-specific (2y-CSS) and 2-year overall survival (2y-OS) related to histopathological tumor stage of RARC patients calculated by Kaplan-Meier method were compared to ORC patients using log-rank test. Early clinical recurrence rate (eCR, progression ≤6 months post-cystectomy) and metastatic pattern of both groups were compared by chi-square test. Results: Median follow-up 32 months (RARC) and 47.5 months (ORC), both groups were balanced in baseline characteristics. For RARC pts, -2y-OS and CSS-free survival rates were 80 and 90%, for ORC pts 65 and 71% (all p > 0.05). Margin status was not significantly different. eCR was observed in 10 out of 89 (11%) RARC pts and in 7 out of 59 (12%) ORC pts (p = 0.9). No difference in atypical metastases was seen between groups. Conclusion: Two-year oncological outcomes of RARC patients are comparable to ORC patients without differences regarding ePR or metastatic pattern.
