Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This phase II trial studies how well stereotactic body radiation therapy works in treating patients with prostate cancer that has not spread to other parts of the body and have undergone surgery. Stereotactic body radiation therapy is a specialized radiation therapy that sends x-rays directly to the tumor using smaller doses over several days and may cause less damage to normal tissue.
