Summary
Brief summary (as posted)
RATIONALE: Radiation therapy uses high-energy x-rays and other sources to damage tumor cells. Giving radiation therapy in different ways may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of external-beam radiation therapy followed by implanted radiation therapy in treating patients who have prostate cancer.
