Shorter, stronger radiation for prostate cancer shows promise in new trial

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Men age 18 or older * Patient has diagnosis of pathologically confirmed prostate cancer, treated with radical prostatectomy. Any type of radical prostatectomy will be permitted, including retropubic, perineal, laparoscopic, or robotically assisted * Patient has pathologic T2-T3M0 stage. Patients can have 5 or less metastatic pelvic lymph nodes confirmed by pathology * For patients radiated in the post-operative salvage setting: pathology can demonstrate any of the following features but not required, positive margin, extracapsular extension, or seminal vesicle involvement with detectable prostate-specific antigen (PSA) of \>= 0.1. PSA \>= 0.1 after radical prostatectomy: most recent PSA value within 12 months of registration and prior to initiating any androgen deprivation therapy (ADT) * Patient diagnosed with Gleason score of 6-10 * Eastern Cooperative Oncology Group (ECOG) performance 0-2 * Patients may receive 6 months and up to 24 months of androgen deprivation therapy. Patients may have received androgen deprivation therapy up to 12 months prior to postoperative radiotherapy * If the patient has a prior history of any cancer other than prostate cancer, he must have completed treatment within 1 year of study registration and the patient must have no evidence of disease of this prior non-prostate cancer Exclusion Criteria: * Prior radiation therapy to prostate/seminal vesicle fossa or postoperative region * Neoadjuvant chemotherapy before or after prostatectomy * History of lupus, scleroderma, or calcinosis, Raynaud's phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia (CREST) syndrome * History of severe active co-morbidity or uncontrolled diabetes * Unstable angina and/or congestive heart failure requiring hospitalization within the last 6 months * Transmural myocardial infarction within the last 6 months * Severe hepatic disease, defined as a diagnosis of Child-Pugh class B or C hepatic disease * End-stage renal disease (i.e., on dialysis or dialysis has been recommended)
