External-Beam Radiation Therapy Plus Implanted Radiation Therapy in Treating Patients With Prostate Cancer

Official Title:

A Phase II Study of External Beam Radiation Therapy Combined With Permanent Source Brachytherapy for Intermediate Risk Clinically Localized Adenocarcinoma of the Prostate

Summary

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.
