Purpose: To assess the effectiveness and safety of robot-assisted radical prostatectomy (RARP) versus laparoscopic radical prostatectomy (LRP) in the treatment of prostate cancer.
Materials and Methods: Existing systematic reviews were updated to investigate the effectiveness and safety of RARP. Electronic databases, including Ovid MEDLINE, Ovid Embase, the Cochrane Library, KoreaMed, Kmbase, and others, were searched through July 2014. The quality of the selected systematic reviews was assessed by using the revised assessment of multiple systematic reviews (R-Amstar) and the Cochrane Risk of Bias tool. Meta-analysis was performed by using Revman 5.2 (Cochrane Community) and Comprehensive Meta-Analysis 2.0 (CMA; Biostat). Cochrane Q and I2 statistics were used to assess heterogeneity.
Results: Two systematic reviews and 16 additional studies were selected from a search performed of existing systematic reviews. These included 2 randomized controlled clinical trials and 28 nonrandomized comparative studies. The risk of complications, such as injury to organs by the Clavien-Dindo classification, was lower with RARP than with LRP (relative risk [RR], 0.44; 95% confidence interval [CI], 1.23?0.85; p=0.01). The risk of urinary incontinence was lower (RR, 0.43; 95% CI, 0.31?0.60; p<0.000001) and the potency rate was significantly higher with RARP than with LRP (RR, 1.38; 95% CI, 1.11?1.70; I2=78%; p=0.003). Regarding positive surgical margins, no significant difference in risk between the 2 groups was observed; however, the biochemical recurrence rate was lower after RARP than after LRP (RR, 0.59; 95% CI, 0.48?0.73; I2=21%; p<0.00001).
Conclusions: RARP appears to be a safe and effective technique compared with LRP with a lower complication rate, better potency, a higher continence rate, and a decreased rate of biochemical recurrence.
