Objectives: To evaluate the prognostic value of positive surgical margins (PSM) in radical prostatectomy ( RPE) specimens in relation to multifocality, localization and size. Methods: A total of 1036 patients who underwent RPE and staged pT2-3a, pN0,M0 were evaluated. None had received adjuvant or neoadjuvant therapy. All specimens were routinely processed by complete whole mount sectioning. Exact number, localization and size of PSM were reassessed, and patients were followed up for a mean of 60 months. Results: A total of 267 patients ( 26%) showed PSM ( 20% pT2, 48% pT3a). Preoperative prostate-specific antigen, Gleason score ( GS) and PSM were independent predictors of biochemical recurrence ( BCR). BCR-free survival rates for patients with and without PSM were 59% and 80%, respectively ( HR 2.1; P < 0.001). PSM were related to biochemical failure in pT2 and pT3a tumors ( P = 0.001 and P = 0.015). A total of 64% of solitary PSM were apical. Multifocality, localization and size of PSM had no significant impact on BCR. Conclusions: Solitary apical and small PSM in RPE have a significant impact on BCR-free survival in localized stages.
