Study Arms:
- Treatment (antihormone therapy and radiation therapy) (Type: EXPERIMENTAL): Patients receive abiraterone acetate and prednisone daily for 24 weeks. Patients also receive leuprolide acetate or goserelin in weeks 1 and 13. Patients undergo external beam radiotherapy starting in week 15 for 8.5 weeks. Treatment continues in the absence of disease progression or unacceptable toxicity.
