Abstract

Purpose: The presence of a positive surgical margin at radical prostatectomy has been linked to an increased risk of postoperative biochemical recurrence. We evaluated the impact of margin status on subsequent clinical progression and mortality. Materials and Methods: We reviewed the records of 11,729 patients who underwent prostatectomy between 1990 and 2006. Survival was estimated for patients with vs without a positive margin and compared using the log rank test. Cox proportional hazards regression models were used to analyze the impact of margin status on survival. Results: Overall 3,651 (31.1%) men were identified with a positive margin. Median postoperative followup was 8.2 years (IQR 4.4, 12.1). The 10-year biochemical recurrence-free rate for patients with and without a positive margin was 56% and 77%, respectively (p
