1829 patients underwent radical prostatectomy with pelvic lymph node dissection (RP+PLND) (241 high-risk, 943 intermediate-risk, 645 low-risk). Positive margin rates were 17.8%, 14.8%, and 11.9% in the high, intermediate-and lowrisk groups. Five-year overall survival was 92.5% in lymph node-positive patients and 94.9% in lymph node-negative patients (p = 0.8). Age, prebiopsy prostatespecific antigen, and clinical stage were associated with positive surgical margins in patients with lymph node metastasis (LNM). Recipients of RP+PLND with LNM and positive surgical margins required adjuvant treatment.
