Incidence of surgical margin involvement in various forms of radical prostatectomy.
The pathologic specimens of 64 patients who underwent radical prostatectomy for clinical Stage A or B carcinoma of the prostate were reviewed retrospectively for surgical margin involvement with cancer. Fourteen of the operations were performed by the radical transperineal method, 30 by the standard radical retropubic approach, and 20 by the nerve-sparing radical retropubic technique. Seventy-eight percent of the radical transperineal group had resection margin involvement, as opposed to 30 percent of the standard radical retropubic cases, and 45 percent of the nerve-sparing radical retropubic cases. The average tumor burden of the transperineal group was larger than that of the other two groups. Resection margin involvement in all groups was associated with a higher Gleason histologic score. No significant difference was noted between the two retropubic groups in terms of resection margin involvement (P = 0.28), suggesting that nerve-sparing radical retropubic prostatectomy does not compromise the surgical goal of radical prostatectomy for carcinoma over that of the standard radical retropubic prostatectomy.
