To provide information about long-term outcome after radical prostatectomy for clinically localized prostatic cancer (stage T2c or lower), we undertook a retrospective analysis of 3,170 consecutive patients (mean age 65.3 +/- 6.4 years, range 31 to 81) with a mean followup of 5 years. Complication rates for patients who underwent prostatectomy before 1988 were compared with those who underwent radical prostatectomy more recently. Of the patients 49 (1.5%), 178 (5.6%), 897 (28%) and 2,047 (65%) had clinical stages T1a, T1b, T2a and T2b,c disease, respectively. The Gleason score was 3 or less in 292 patients (9%) and 7 or greater in 782 (25%). Overall, 438 patients (14%) died, 159 (5%) of cancer. The crude 10 and 15-year survival rates for all patients were 75% and 60%, respectively, which is comparable to the expected survival of a control group (67% and 46%). The cause specific survival rates were 90% and 82%, respectively, metastasis-free survival rates 82% and 76%, local recurrence-free survival rates 83% and 75%, overall recurrence-free rates 72% and 61%, and overall recurrence plus prostate specific antigen progression-free (greater than 0.2 ng./ml.) rates 52% and 40%, respectively. Clinical stage did not significantly affect survival but tumor grade was associated: 10 and 15-year cause specific survival rates were 95% and 93%, respectively, for a Gleason score of 3 or less, 90% and 82%, respectively, for a score of 4 to 6, and 82% and 71%, respectively, for a score of 7 ...
