BACKGROUND: Although a positive surgical margin (PSM) at radical prostatectomy (RRP) has been consistently linked to an increased risk of biochemical recurrence, the impact of margin status on patient survival continues to be debated. We evaluated long-term outcomes of patients with a PSM at RRP and determined predictors of systemic progression (SP) and mortality in these men. METHODS: We reviewed our institutional registry of 16,749 patients who underwent RRP between 1990 and 2008 to identify 2895 patients with a PSM. Median follow-up was 10.6 years. Postoperative survival was estimated using the Kaplan-Meier method. Cox proportional hazard regression models were used to analyze clinicopathological variables associated with SP and death from prostate cancer. RESULTS: A 15-year SP-free and cancer-specific survival was 90 and 93%, respectively. On multivariate analysis, higher tumor volume, increased pathological Gleason score and advanced pathological tumor stage were associated with significantly increased risks of SP and death from prostate cancer, whereas number and location of PSM did not predict mortality. CONCLUSIONS: The risks of SP and prostate cancer death in patients with a PSM remain low on long-term follow-up. Tumor variables are the primary determinants of cancer death. These results should be considered when evaluating patients with a PSM for adjuvant therapy.
