The purpose of this study is to compare any good and bad effects of using stereotactic body radiation therapy (SBRT), a technique that gives treatment in a shorter amount of time compared to the usual radiation therapy. SBRT is experimental for treating this type of cancer. In certain regions, there are authored local coverage determinations that identify SBRT as a routine care service for this disease. SBRT uses special equipment to position a participant and precisely deliver radiation to tumors in the body. Both the study and the usual radiation treatments use daily images to guide the radiation treatment to protect normal tissue. The study treatment, treatment over a shorter amount of time, may prevent the tumor from returning but it could also cause side effects. This study will allow the researchers to know whether this different approach using SBRT is better, the same, or worse than the usual approach. To be better, the study treatment should increase the time without the cancer coming back by six months or more compared to the usual approach, and show improvements in side effects to the bladder or rectum.
