BACKGROUND: We report long-term oncologic outcomes in patients with positive surgical margins (PSMs) at radical prostatectomy (RP) and the oncologic impact of different scenarios of PSMs presentation. METHODS: We selected 494 men with at least 3 years follow-up after surgery. PSMs patterns were recorded as: burden (focal vs multifocal), site (apical-anterior vs posterolateral vs base-bladder neck vs multiple) and side (unilateral vs bilateral). Kaplan-Meier curves depicted the clinical recurrence-free survival (CR-FS) rates at 10-year in the overall population, after biochemical recurrence and according to different PSMs patterns. Multivariate Cox-regression analysis was performed to predict CR. RESULTS: Overall, PSMs sites were apical-anterior, postero-lateral, base-bladder neck and multiple in 19.8%, 23.7%, 3.4% and 43.8%, respectively. Out of 494 patients, 278 (56.3%) had a focal margin, while 216 (43.7%) had a multifocal margin. In 268 (54.3%) and 87 (17.6%) men, PSMs were unilateral and bilateral, respectively. Median follow-up was 93 months. No significant differences were found in CR-FS rates after stratifying according to burden and site of PSMs. Men with unilateral PSMs experienced significant higher CR-FS rates compared to those with bilateral PSMs (87.1% vs. 71,3% at 10 years, p
