Impact of positive surgical margins (PSMs) after robotic prostatectomy on biochemical recurrence (BCR): Multicenter analysis.

Objective: To study and analyze any correlations between positive surgical margins after RARP and biochemical recurrence.

Methods: We enrolled 105 patients who underwent robot-assisted radical prostatectomy (RARP) from 2016-2020 with PSMs on final pathology, all performed or supervised by a senior surgeon in two tertiary referral center. Pathology has been described indicating also the area (apical, base, mediolateral, anterior, or multiple) and the extent of PSMs: focal (≤3 mm) or extensive (>3 mm).
