Abstract: BACKGROUND: Because of the lack of results from randomized clinical trials comparing the efficacy of aggressive therapies with that of more conservative therapies for clinically localized prostate cancer, men and their physicians may select treatments based on other criteria. We examined the association of sociodemographic and clinical characteristics with four management options: radical prostatectomy, radiation therapy, hormonal therapy, and watchful waiting. METHODS: We studied 3073 participants of the Prostate Cancer Outcomes Study diagnosed from October 1, 1994, through October 31, 1995, with clinically localized disease (T1 or T2). Participants completed a baseline survey, and diagnostic and treatment information was abstracted from medical records. Multiple logistic regression analysis identified factors associated with initial treatment. All statistical tests were two-sided. RESULTS: Patients with clinically localized disease received the following treatments: radical prostatectomy (47.6%), radiation therapy (23.4%), hormonal therapy (10.5%), or watchful waiting (18.5%). Men aged 75 years or older more often received conservative treatment (i.e., hormonal therapy alone or watchful waiting; 57.9% of men aged 75-79 years and 82.1% of men aged 80 years and older) than aggressive treatment (i.e., radical prostatectomy or radiation therapy) (for all age groups, P
