Title Prostate Radiation Therapy or Short-Term Androgen Deprivation Therapy and Pelvic Lymph Node Radiation Therapy With or Without Prostate Radiation Therapy in Treating Patients With a Rising Prostate Specific Antigen (PSA) After Surgery for Prostate Cancer
Conditions Prostate Cancer
Interventions Drug: bicalutamide
Drug: flutamide
Radiation: radiation therapy
Phase Phase 3
Purpose RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Androgens can cause the growth of prostate cancer cells. Antihormone therapy, such as flutamide, bicalutamide, and luteinizing hormone-releasing hormone agonist, may lessen the amount of androgens made by the body. It is not yet known which regimen of radiation therapy with or without androgen-deprivation therapy is more effective for prostate cancer. PURPOSE: This randomized phase III trial is studying prostate radiation therapy to see how well it works compared with short-term androgen deprivation therapy given together with pelvic lymph node radiation therapy with or without prostate radiation therapy in treating patients with a rising PSA after surgery for prostate cancer.
Eligibility Ages Eligible: 18 Years
Genders Eligible:  Male
Accepts Healthy Volunteers:  No
  • Adenocarcinoma of the prostate treated primarily with radical prostatectomy - Pathologically proven to be lymph node-negative by pelvic lymphadenectomy (N0) or lymph node status pathologically unknown (Nx [undissected pelvic lymph nodes because lymph node dissection is not required]) - Any type of radical prostatectomy allowed, including retropubic, perineal, laparoscopic, or robotically assisted - Meets 1 of the following pathologic classifications: - T3 N0/Nx disease with or without positive prostatectomy margins - T2 N0/Nx disease with or without positive prostatectomy margins - N1 patients are ineligible, as are those with pelvic lymph node enlargement ≥ 1.5 cm in greatest dimension by CT scan or MRI of the pelvis, unless the enlarged lymph node is negative - Prostatectomy Gleason score of 9 or less
  • A post-radical prostatectomy entry PSA of ≥ 0.1 and ≤ 1.0 ng/mL at least 6 weeks after prostatectomy and within 30 days of registration
  • Serum total testosterone ≥ 40% of the lower limit of normal (patients who have had a unilateral orchiectomy are eligible as long as this requirement is met)
  • No distant metastases based on history/physical examination, CT scan or MRI of the abdomen and pelvis, and bone scan
  • No palpable prostatic fossa abnormality/mass suggestive of recurrence, unless shown by biopsy under ultrasound guidance not to contain cancer PATIENT CHARACTERISTICS:
  • Zubrod performance status 0-1
  • Platelets ≥ 100,000/mm^3
  • Hemoglobin ≥ 10.0 g/dL (the use of transfusion or other intervention to achieve this is allowed)
  • Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) < 2 x upper limit of normal
  • No prior invasive malignancy (except nonmelanoma skin cancer) or superficial bladder cancer unless disease free for a minimum of 5 years (e.g., carcinoma in situ of the oral cavity is permissible)
  • No severe, active co-morbidity, including any of the following: - History of inflammatory bowel disease - History of hepatitis B or C - Unstable angina and/or congestive heart failure requiring hospitalization within the past 6 months - Transmural myocardial infarction within the past 6 months - Acute bacterial or fungal infection requiring intravenous antibiotics at the time of registration - Chronic obstructive pulmonary disease exacerbation or other respiratory illness requiring hospitalization or precluding study therapy at the time of registration - Hepatic insufficiency resulting in clinical jaundice and/or coagulation defects - Acquired immune deficiency syndrome (AIDS) based upon current Centers for Disease Control (CDC) definition - HIV testing is not required for entry
  • No prior allergic reaction to the study drug(s) involved in this protocol PRIOR CONCURRENT THERAPY:
  • See Disease Characteristics
  • More than 5 years since prior chemotherapy for any other disease site
  • No androgen-deprivation therapy started prior to prostatectomy for > 6 months duration - The use of finasteride or dutasteride (± tamsulosin) for longer periods prior to prostatectomy is acceptable
  • No androgen-deprivation therapy started after prostatectomy and prior to registration - The use of finasteride or dutasteride (± tamsulosin) after prostatectomy is not acceptable, it must be stopped within 3 months after prostatectomy
  • No neoadjuvant chemotherapy before or after prostatectomy
  • No prior cryosurgery or brachytherapy of the prostate (prostatectomy should be the primary treatment and not a salvage procedure)
  • No prior pelvic radiotherapy
