OBJECTIVE: To evaluate the efficacy of primary hormone therapy for localized or locally advanced prostate cancer, by analysing the 10-year survival rates for men with localized or locally advanced prostate cancer treated withprimary hormone therapy or prostatectomy. PATIENTS AND METHODS: Between February 1993 and March 1995, men with T1b, T1c or T2-3N0M0 prostate cancer were enrolled. In all, 176 men who had a prostatectomy were assigned to Study 1 and were given adjuvant luteinizing hormone-releasing hormone (LHRH) agonist; 151 men who did not have a prostatectomy were assigned to Study 2 and hadLHRH agonist monotherapy or combined androgen blockade. They were followed until death, loss to follow-up, or until the end of the observation period (31 March 2004). We analysed all cases in each study as a single population, and compared Study 1 with Study 2. RESULTS: The mean patient ages were 67.2 years in Study 1 and 75.7 years in Study 2. During a median of 10.4 years of follow-up, 20 men in Study 1 and 17 in Study 2 died from prostate cancer, and 21 men in Study 1 and 50 in Study 2 died from other causes. In Study 1, the 10-year overall survival rate was 73% and the 10-year cause-specific survival rate was 86%, vs 41% and 78% in Study 2. Overall survival curves were similar to expected survival curves in both studies. There was no significant difference between studies in cause-specific survival. CONCLUSIONS: The progression of prostate cancer was retarded by primary hormone therapy in men with localized or locally advanced prostate cancer. With primary hormone therapy or prostatectomy, the men had a life-expectancy similar to that of the normal population.
