OUTLINE: This is a randomized, multicenter study. Patients are stratified according to Gleason score (2-4 vs 5-7 vs 8-10), PSA level (less than 10 ng/mL vs 10-50 ng/mL vs 51-100 ng/mL vs more than 100 ng/mL), and concurrent bisphosphonate therapy (yes vs no). Patients are randomized to one of two treatment arms.
