  Background: One of surgical goals is decreasing of positive resection margin (PRM). In radical prostatectomy, PRM is important because of prognostic factor. We examine the relationship of PRM, cancer location and learning curve after laparoscopic radical prostatectomy (LRP). Methods: Between May, 2009 and May, 2015, 331 consecutive patients were treated with LRP. The resection margin status, Gleason score, pathological stage, cancer location and diameter were assessed in each surgical specimen, and the independent factors for PRM and prostate-specific antigen (PSA) failure were identified. The learning curve for PRM was calculated and the number of cases until the plateau was obtained. Results: PRM was found in 30.5% of all patients, with 27.7% in the pT2 patients and 39.0% in the pT3 patients. The most common site.. View More»
