Adenocarcinoma of the Prostate
Stage II Prostate Cancer
Stage III Prostate Cancer
Stage IV Prostate Cancer
RATIONALE: Androgens can cause the growth of prostate cancer cells. Antihormone therapy, such as abiraterone acetate (Zytiga), leuprolide acetate, and goserelin, may lessen the amount of androgens made by the body. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving abiraterone acetate and leuprolide acetate or goserelin before or together with radiation therapy may be an effective treatment for prostate cancer.
PURPOSE: This phase II trial is studying the side effects and how well giving abiraterone acetate, prednisone, and leuprolide acetate or goserelin before and during radiation therapy works in treating patients with localized or locally advanced prostate cancer.
