Brief Summary: RATIONALE Radiation therapy uses high-energy x-rays to damage tumor cells Giving radiation therapy in different ways may cause less damage to normal tissue and may improve quality of life and help patients live more comfortably Androgens can stimulate the growth of prostate cancer cells Drugs such as goserelin and bicalutamide may fight cancer by stopping the production of androgens It is not yet known whether radiation therapy is more effective with or without goserelin and bicalutamide in treating prostate cancer

PURPOSE Randomized phase III trial to compare the effectiveness of high-dose radiation therapy with or without bicalutamide and goserelin in treating patients who have prostate cancer
Detailed Description: OBJECTIVES

Compare the quality of life of patients with high-grade intermediate-risk or unfavorable-risk adenocarcinoma of the prostate when treated with high-dose intensity-modulated radiotherapy alone versus with androgen deprivation comprising bicalutamide and goserelin
Compare the prostate-specific antigen relapse-free distant metastases-free and overall survival of patients treated with these regimens
Compare the toxicity of these regimens in these patients
Compare the local control in patients treated with these regimens based on post-treatment sextant biopsies performed 4 years after study completion

OUTLINE This is a randomized study Patients are stratified according to prostate-specific antigen level Gleason score and clinical stage Patients are randomized to 1 of 2 treatment arms

Arm I Patients undergo high-dose intensity-modulated radiotherapy IMRT 4-5 times per week for 10 weeks a total of 48 treatments
Arm II Patients receive oral bicalutamide once daily for 185 weeks Three to seven days after the initiation of bicalutamide patients also receive goserelin subcutaneously monthly for 2 years Beginning after 10 weeks of hormonal therapy patients undergo concurrent high-dose IMRT 4-5 times per week for 85 weeks a total of 42 treatments Patients discontinue bicalutamide on or near the end of radiotherapy

In both arms treatment continues in the absence of disease progression or unacceptable toxicity

Quality of life is assessed at baseline every 3 months for 15 years after the completion of radiotherapy then 6 months later and then annually for 2 years

Patients are followed every 6-8 months for 4 years and then annually for 2 years

PROJECTED ACCRUAL A total of 400 patients 200 per treatment arm will be accrued for this study within 4-5 years
