This study is for men who have high-risk prostate cancer who plan to be treated with a combination of radiation and hormonal therapy. A tumor genomic analysis (Decipher score) will be used to divide the subjects into two groups. Those with a low genomic risk score will be randomized to either standard treatment with radiation and 24 months of hormonal therapy or to radiation with a shorter, 12 month, course of hormone therapy. Those with a higher genomic risk score or who have lymph node involvement will be randomized to standard treatment with radiation and 24 months of standard hormonal therapy or radiation with 24 months of intensified hormonal therapy.
