Feasibility of Hormones and Radiation for Intermediate or High Risk Prostate Cancer

The purpose of this study is see if quality of life is improved in patients receiving oral hormone therapy compared to standard of care. The study will also compare survival rates between patients receiving oral hormone therapy and those receiving standard of care.

* Zubrod Performance Status 0-2
* Age \> or = 18
* Baseline serum PSA within 60 days prior to registration
* Baseline serum testosterone obtained within 60 days prior to registration
* Study entry PSA and serum testosterone must not be obtained during the following time frames, 10-day period following prostate biopsy, following initiation of oral androgen manipulation, within 30 days after discontinuation of finasteride or dutasteride
* CBC/ differential obtained within 60 days prior to registration with adequate bone marrow function
* Patient must be able to provide study-specific informed consent prior to study entry

Exclusion Criteria:

* Prior radical surgery (prostatectomy), high-intensity focused ultrasound (HIFU) or cryosurgery for prostate cancer
* Prior hormonal therapy, such as LHRH agonists (e.g., goserelin, leuprolide), antiandrogens (e.g., flutamide, bicalutamide), estrogens (e.g., DES), or bilateral orchiectomy
* Use of 5-alpha reductase inhibitors (finasteride, dutasteride) specifically prescribed for the treatment of prostate cancer
* Prior or concurrent cytotoxic chemotherapy for prostate cancer; prior chemotherapy for a different cancer is permitted
* Prior radiation, including brachytherapy, to the region of the prostate that would result in overlap of RT fields
* Active lupus or scleroderma
* Severe, active co-morbidity, including but not limited to,unstable angina within the last 6 months without subsequent corrective cardiovascular procedure,or acute bacterial or fungal infection requiring intravenous antibiotics at the time of registration
* Hepatic insufficiency with AST, ALT, or Bilirubin \> 2 x upper limit of normal,clinical jaundice, and/or coagulation defects
* Acquired Immune Deficiency Syndrome (AIDS); note, however, that HIV testing is not required for entry into this protocol.Patients who are HIV seropositive but do not meet criteria for diagnosis of AIDS are eligible for study participation
