Abstract
Purpose
This study aimed at reporting the long-term oncological outcomes of robotic partial nephrectomy (RPN) for renal cell carcinoma (RCC).
Methods
Data from all consecutive patients who underwent RAPN for RCC from July 2009 to January 2012 in three departments of urology were prospectively collected. Overall survival (OS), cancer-specific survival (CSS) and disease free-survival (DFS) were estimated using the Kaplan–Meier method. Prognostic factors associated with CSS were sought in univariate analysis. The log-rank test was used for categorical variables and the Cox model for continuous variables.
Results
110 patients were included with a median follow-up of 64.4 months [95% CI = (61.0–66.7)]. Median age was 61 years (29–83) with 62.7% of men and 37.3% of women. Median RENAL score was 6 (4–10) with elective indications accounting for 95% of cases. Out of 27 patients (24.5%) who experienced peri-operative complication, 12 patients (10.9%) had a major complication (Clavien-Dindo grade ≥ 3). The TRIFECTA achievement rate was 52.7%. Three patients (2.7%) experienced local recurrence and seven patients (6.4%) progressed to a metastatic disease. 5-year OS, CSS, DFS were 94.9, 96.8, 86.4%, respectively. In univariate analysis, no pre/peri-operative characteristic was associated with DFS. No port-site metastasis was observed and there was one case of peritoneal carcinomatosis.
Conclusion
In this multicenter series, long-term OS, DFS and CSS after RPN appeared comparable to large series of open partial nephrectomy, with no port-site metastasis and one case of peritoneal carcinomatosis.
