ABSTRACT
Objective:
To identify risk factors for positive surgical margin after laparoscopic radical prostatectomy.Method:
The study retrospectively analyzed the records of 177 patients with prostate cancer who eventually underwent laparoscopic radical prostatecto-my from January 2016 to December 2017 in Peking University First Hospital. Age, prostate volume, prostate-specific antigen (PSA) be-fore needle biopsy, number of positive cores, positive percentage of needle biopsy and biopsy, and postoperative Gleason scoreand pathological stage were analyzed.Results:
The overall positive surgical margin rate was 32.2% (57/177). Age, prostate volume, PSA be-fore needle biopsy, positive percentage of biopsy, and postoperative Gleason score were not significantly different (P>0.05). The study demonstrated significant differences between the number of positive cores, positive percentage of needle biopsy, and pathological stage (P<0.05). Multiple logistic regression revealed that the pathological stage was an independent factor affecting the positive surgi-cal margin rate (odds ratio, 1.616; 95% confidence interval, 1.062-2.459).Conclusions:
The number of positive cores, positive percent-age of needle biopsy, and pathological stage significantly correlated with a positive surgical margin. The postoperative pathological T stage is an independent factor affecting positive surgical margins.
