Radiotherapy Plus Hormone Therapy in Biochemically-relapsing Prostate Cancer Patients Following Surgery

As there is no prospective data on the combination of abiraterone and salvage radiotherapy, the aim of this study is to further evaluate the safety profile of abiraterone acetate plus prednisone in patients with prostate cancer who are biochemically relapsing after surgery and undergo salvage radiotherapy with 6-months LH-RH agonist. The investigators hypothesize that the toxicity profile of both treatments should not potentiate each other. This study will also provide preliminary data on the efficacy of this combination.
