N2 - Studies detailing differences in positive surgical margin among open retropubic radical prostatectomy, laparoscopic radical prostatectomy, and robotic-assisted laparoscopic radical prostatectomy are lacking. A retrospective review of all prostatectomies with positive surgical margin performed at our center in 2007 disclosed 99 cases, 6 (5%) of which were reinterpreted cases as having negative margins. Ninety-three cases were, therefore, included, corresponding to 37 retropubic radical prostatectomies, 19 laparoscopic radical prostatectomies, and 37 robotic-assisted laparoscopic radical prostatectomies. The relationship of positive surgical margin characteristics to clinicopathologic parameters and biochemical recurrence was assessed. The most commonly found positive surgical margin site was the apex/distal third in all groups (62% retropubic prostatectomies, 79% laparoscopic prostatectomies, 60% robotic-assisted prostatectomies). Total linear length of positive surgical margin sites was significantly correlated with preoperative prostate-specific antigen, preoperative prostate-specific antigen density, pT stage, and tumor volume (P ≤.001). We found no significant differences among the 3 groups with respect to total linear length, number of foci, laterality, or location of positive surgical margin. The rate of biochemical recurrence was also comparable in the 3 groups. On univariate analyses, biochemical recurrence was significantly associated with preoperative prostate-specific antigen values, preoperative prostate-specific antigen density, Gleason score, number of positive surgical margins, and total linear length of positive surgical margin (P ≤.02). Only preoperative prostate-specific antigen density and number of positive surgical margin foci were statistically significant (P ≤.03) independent predictors of biochemical recurrence. We found no significant difference in positive surgical margin characteristics or biochemical recurrence among the 3 radical prostatectomy modalities. Preoperative prostate-specific antigen density and number of positive surgical margin foci were the only independent predictors of biochemical recurrence.
