Robot-assisted radical prostatectomy significantly reduced biochemical recurrence compared to retro pubic radical prostatectomy

BACKGROUND: The pathological and oncological outcomes of retro-pubic radical prostatectomy (RRP) and robot-assisted radical prostatectomy (RARP) have not been sufficiently investigated. METHODS: Treatment-naïve patients with localized prostate cancer (PC) (n = 908; RRP, n = 490; and RARP, n = 418) w...

Sumario:BACKGROUND: The pathological and oncological outcomes of retro-pubic radical prostatectomy (RRP) and robot-assisted radical prostatectomy (RARP) have not been sufficiently investigated. METHODS: Treatment-naïve patients with localized prostate cancer (PC) (n = 908; RRP, n = 490; and RARP, n = 418) were enrolled in the study. The clinicopathological outcomes, rate and localization of the positive surgical margin (PSM), localization of PSM, and biochemical recurrence (BCR)-free survival groups were compared between RRP and RARP. RESULTS: The median patient age and serum PSA level (ng/mL) at diagnosis were 67 years and 7.9 ng/ml, respectively, for RRP, and 67 years and 7.6 ng/ml, respectively, for RARP. The overall PSM rate with RARP was 21%, which was 11% for pT2a, 12% for pT2b, 9.8% for pT2c, 43% for pT3a, 55% for pT3b, and 0% for pT4. The overall PSM rate with RRP was 44%, which was 12% for pT2a, 18% for pT2b, 43% for pT2c, 78% for pT3a, 50% for pT3b, and 40% for pT4. The PSM rate was significantly lower for RARP in men with pT2c and pT3a (p < 0.0001 for both). Multivariate analysis showed that RARP reduced the risk of BCR (hazard ratio; 0.6, p = 0.009). CONCLUSIONS: RARP versus RRP is associated with an improved PSM rate and BCR. To examine the cancer-specific survival, further investigations are needed.
