Site of positive surgical margins influences biochemical recurrence after radical prostatectomy

OBJECTIVE To determine whether the number and location of positive surgical margins (PSMs) in radical prostatectomy (RP) surgical specimens affect biochemical recurrence (BCR) rates. PATIENTS AND METHODS The locations of PSMs were recorded for 1308 consecutive men who underwent RP between October 2000 and December 2006. BCR was defined as three consecutive prostate‐specific antigen (PSA) level rises with the peak level ≥0.15 ng/mL. Multivariate...
