Radical prostatectomy. Patterns of local failure and survival in 67 patients

Sixty-seven patients with localized carcinoma of the prostate were treated by radical prostatectomy unaided by adjunctive hormonal therapy. Seven patients (10%) have been lost to follow-up, and 13 patients (19%) have died of other causes without evidence of prostate cancer. The crude or direct survival free of disease for traced patients with clinical Stage B1 nodules (11) and clinical B2 lesions (20) followed for at least fifteen years is 36 per cent and 25 per cent, respectively; the crude or direct survival free of disease for pathologic B (29) and C (12) tumors followed for fifteen years is 31 per cent and 8 per cent, respectively. The local failure incidence at fifteen years for pathologic Stage B tumors is 17 per cent and for pathologic C tumors 31 per cent. Capsular invasion alone on histologic examination did not increase the rate of local or distant failure above that noted for tumors that were entirely intracapsular. However, seminal vesicle invasion is associated with a 44 per cent local failure and 66 per cent distant failure rate. The interval between radical prostatectomy and first failure averaged sixty-nine months (median 56 months) and with hormonal therapy the interval between first failure and death averaged seventy months (median 62 months). The patients who underwent radical prostatectomy in this series represent 22 per cent of the 318 patients presenting with localized prostate cancer between 1960 and 1974. A 1.5-cm nodule was found in 5.5 per cent of the presenting population, and all but one of these patients were treated by radical prostatectomy.
