Radiation Therapy and Hormone Therapy in Treating Patients With Prostate Cancer
Prostate Cancer

About this trial
This is an interventional treatment trial for Prostate Cancer focused on measuring adenocarcinoma of the prostate, stage I prostate cancer, stage IIB prostate cancer, stage IIA prostate cancer, stage III prostate cancer, stage IV prostate cancer
Eligibility Criteria
DISEASE CHARACTERISTICS: Histologically confirmed adenocarcinoma of the prostate Any stage with an estimated risk of node involvement at least 15% (and therefore at significant risk for local and/or systemic failure) based on pretreatment PSA and Gleason score (GS), e.g.: GS of 7 and PSA greater than 7.5 ng/mL GS of 6 and PSA greater than 22.5 ng/mL GS of 5 and PSA greater than 37.5 ng/mL PSA greater than 4 and less than 100 ng/mL Highest pretreatment value determined by a monoclonal assay that has a normal range of 0-4 ng/mL PSA measured by polyclonal assay (e.g., Yang) that has a normal range of 0-2.5 ng/mL may need to be divided by a conversion factor of approximately 1.5 GS determination required prior to entry No distant metastases No biopsy proven lymph node involvement Ineligible for protocol RTOG-9408 (clinical stages T2c-T4 with GS of 6 or higher are eligible for this study)
PATIENT CHARACTERISTICS: Age: Any age Performance status: Karnofsky 70-100% Hematopoietic: Not specified Hepatic: Liver function tests no greater than 1.2 times normal Renal: Not specified Other: No major medical or psychiatric illness that would prevent completion of treatment or interfere with follow-up No second malignancy within 5 years except superficial nonmelanomatous skin cancer
PRIOR CONCURRENT THERAPY: Biologic therapy: Not specified Chemotherapy: No prior chemotherapy Endocrine therapy: At least 90 days since testosterone At least 60 days since finasteride Radiotherapy: No prior radiotherapy Surgery: No more than 60 days since surgical staging No radical surgery or cryosurgery
