Summary
Brief summary (as posted)
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. It is not yet known which dose of radiation therapy is more effective in treating patients with prostate cancer. PURPOSE: This randomized phase III trial is comparing two radiation therapy regimens in treating patients with prostate cancer receiving hormone therapy.
