Background: Metastatic castration sensitive and castration resistant prostate cancer (mCSPC and mCRPC) are prostate cancers that have spread to other parts of the body. Use of the drug docetaxel with androgen deprivation therapy can improve survival for men with mCSPC. Researchers want to see if combining this treatment with other drugs can help delay the time it takes for mCSPC and mCRPC to get worse.

Summary: For this study, high risk prostate cancer patients with lower risk ARTERA scores will be treated with 6 months of Androgen Deprivation Therapy (ADT) in conjunction with dose escalated radiotherapy to the prostate and nodes. Specifically, patients enrolled in this study will undergo one of several dose-escalated forms of radiotherapy which would include SBRT with or without a brachytherapy boost.
