[RETROSPECTIVE ANALYSIS OF POSITIVE SURGICAL MARGIN AT RADICAL PROSTATECTOMY].

ABSTRACT

We retrospectively reviewed 182 patients who underwent radical prostatectomy in our hospital between April, 2009 to December, 2012, and who had not received any prior hormonal therapy. We also excluded the patients who couldn't followed up more than 6 months after surgery and pN1 patients. Positive surgical margins were observed in 65 cases. We determined what were the significant factors associated with the margin status. The another aim of present study is to evaluate the risk factor which might have significance for biochemical recurrence. BMI ≥ 25.0, prostate volume < 40 cm3, and biopsy positive core ≥ 25% were significant predictors of positive surgical margin. PSA nadir ≥ 0.02 ng/ml and pT3 were the significant factors which associated with biochemical recurrence of those patients with positive margin status.
