Abstract

To examine the association between cancer location, resection margins and oncological outcome in patients undergoing radical prostatectomy. A total of 505 patients who underwent radical prostatectomy between 1993 and 2009 were included in this analysis. Cancer location, resection margins and pathological factors were assessed based on the 2010 General Rules for Clinical and Pathological Studies on Prostate Cancer. Biochemical recurrence was defined as prostate-specific antigen >0.2 ng/mL. Positive resection margins were found in 38.4% of all cases, in 30.3% of pT2 cases and in 57.7% of pT3 cases. The cancer was distributed evenly among the apex-anterior, apex-posterior and middle lesions, which each accounted for approximately 30% of the whole lesion in the main tumor. A higher rate of positive resection margins (47.6%) was found in the apex-anterior lesions. In minor tumors, most cancer was located in the middle lesion and accounted for approximately 60% of the lesion. However, positive resection margins were detected significantly more frequently in the apex-anterior lesion of minor tumors. The 5-year and 10-year biochemical recurrence-free survival rates were 36.2% and 32.0%, respectively, in patients with a positive resecti...Continue Reading
