Abstract

BACKGROUND:

Limited data are available on the role of robot-assisted radical prostatectomy (RARP) in patients with locally advanced prostate cancer (PCa).

OBJECTIVE:

To describe our surgical technique of extrafascial RARP and extended pelvic lymph node dissection (ePLND) in locally advanced PCa.

DESIGN, SETTING, AND PARTICIPANTS:

Ninety-four patients with clinical stage ≥T3 undergoing RARP with ePLND at three European centers between 2011 and 2015 were retrospectively evaluated.

SURGICAL PROCEDURE:

Surgery was performed using the DaVinci Si system. The anatomically defined ePLND included nodes overlying the external iliac axis, those in the obturator fossa, and around the internal iliac artery up to the ureter. RARP was performed using an extrafascial approach where the Denonvillers' fascia was dissected free and left on the posterior surface of the seminal vesicles.

MEASUREMENTS:

Perioperative outcomes consisted of operative time, blood loss, length of hospital stay, and complications occurred within 30 d after surgery. Biochemical recurrence (BCR) was defined as two consecutive prostate-specific antigen values ≥0.2ng/ml. Kaplan-Meier analyses assessed time to BCR and clinical recurrence. Multivariable Cox regression analyses assessed predictors of BCR.

RESULTS AND LIMITATIONS:

Median operative time, blood loss, and length of hospital stay were 230min, 200ml, and 6 d. Overall, 12 (12.7%) patients experienced complications and five (5.3%), four (4.3%), and three (3.2%) patients had Clavien I, II, and III/IV complications. Overall, 72 (76.6%), 35 (37.2%), and 30 (32.3%) patients had pT3/4, pN1, and positive margins. The median number of nodes removed was 16. Overall, 19 (20.2%) and 21 (22.3%) patients received adjuvant radiotherapy and hormonal therapy. The median follow-up was 23.5 mo. At 3-yr follow-up, the BCR- and clinical recurrence-free survival rates were 63.3% and 95.8%. Pathologic stage, Gleason score, and positive margins represented predictors of BCR (all p≤0.03). Our study is limited by its retrospective nature and by the follow-up duration.

CONCLUSIONS:

RARP represents a well-standardized, safe, and oncological effective option in patients with locally advanced PCa. Pathologic stage, Gleason score, and positive margins should be considered to select patients for multimodal approaches.

PATIENT SUMMARY:

Robot-assisted surgery represents a well-standardized, safe, and oncological effective option in men with locally advanced prostate cancer. Two out of three patients treated with this approach are free from recurrence at 3-yr follow-up. Pathologic stage, Gleason score, and positive surgical margins represent predictors of BCR and should be considered to select patients for multimodal approaches.
