Conditions: Biochemically Recurrent Prostate Carcinoma, Oligometastatic Prostate Carcinoma, Recurrent Prostate Adenocarcinoma, Stage IIB Prostate Cancer AJCC v8, Stage IIC Prostate Cancer AJCC v8
Interventions: Antiandrogen Therapy, Biospecimen Collection, Hypofractionated Radiation Therapy, Positron Emission Tomography, Stereotactic Body Radiation Therapy
Countries: United States
This phase III trial tests the side effects of stereotactic body radiation therapy (SBRT) compared to hypofractionated radiotherapy for treating patients with prostate adenocarcinoma that has come back after a period of improvement (recurrent) or that has spread from where it first started (primary site) to a limited number of sites (oligometastatic). SBRT is a type of external radiation therapy that uses special equipment to position a patient and precisely deliver radiation to tumors in the body (except the brain). The total dose of radiation is divided into smaller doses given over several days. This type of radiation therapy helps spare normal tissue. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumors cells and have fewer side effects. SBRT may work just as well as hypofractionated radiation therapy at treating patients with biochemically recurrent or oligometastatic prostate cancer, but with a shorter treatment time and possibly fewer side effects.
