Radiation Therapy With or Without Antiandrogen Therapy in Treating Patients With Stage I or Stage II Prostate Cancer

Summary

RATIONALE: Radiation therapy (RT) uses high-energy x-rays to damage tumor cells. Androgens can stimulate the growth of prostate cancer cells. Hormone therapy using flutamide, goserelin, and leuprolide may fight prostate cancer by reducing the production of androgens. It is not yet known which regimen of antiandrogen therapy is most effective for prostate cancer. PURPOSE: Randomized phase III trial to study the effectiveness of radiation therapy with or without antiandrogen therapy in treating patients who have stage I or stage II prostate cancer.
