title: Incidental adenocarcinoma of the prostate: a retrospective analysis.
abstract: Between January 1980 and June 1990, 5875 patients underwent either TURP (5,529) or open prostatectomy (346) for the management of benign prostatic hyperplasia. Incidental carcinoma was identified in 53 patients (0.9%) - 49 in the TURP group and 4 in the open prostatectomy group. The overall incidence of stage A prostate carcinoma during the same period was 13.1% (53/406). Of those 50 regularly followed patients, only 6 (12.0%) underwent subsequent radical prostatectomy with pelvic lymphadenectomy, and residual tumors were identified in 4 patients (66.7%). The progression rate was 33.3% (3/9) in high-grade tumors (Gleason's score greater than 6) and 7.7% (2/26) in low-grade tumors (Gleason's score less than 5). In those 50 patients, 41 (82.0%) presented no evidence of disease and 9 (18.0%) stayed alive with progression. The mean length of follow-up was 34 months (range: 2-108 months). Our study demonstrates that the outcome of incidental carcinoma of the prostate is good. However, the residual tumor rate still remains high at 66.7%. Radical prostatectomy is recommended in young patients or in patients with high grade tumor.
