1164: The Influence of Increasing Experience and Surgical Technique on Surgical Margin Status in Patients Undergoing Open and Robotic Prostatectomy by a Single Surgeon

摘要

RESULTS: Of 384 men with low-risk prostate cancer, 1 or 2 cores positive, and unilateral disease on prostate biopsy, only 109 (28.4%) had unilateral disease following examination of radical prostatectomy specimens. Men with pathologically unilateral disease did not differ from those with bilateral or more advanced disease by age, PSA, BMI or number of positive biopsy cores (1 vs. 2) (see table). On multivariable analysis, no clinical feature was significantly related to pathologically unilateral vs. bilateral or greater disease.
