This randomized phase III trial studies androgen-deprivation therapy and radiation therapy in treating patients with prostate cancer. Androgens can cause the growth of prostate cancer cells. Androgen deprivation therapy may stop the adrenal glands from making androgens. Radiation therapy uses high-energy x-rays to kill tumor cells.
Further Study Information
I. Demonstrate that prophylactic, neoadjuvant, androgen-deprivation therapy (NADT) and whole-pelvic radiation therapy (WPRT) will result in improvement in overall survival (OS) of patients with “unfavorable” intermediate-risk or “favorable” high-risk prostate cancer compared to NADT and high-dose prostate and seminal vesicle (SV) radiation therapy (prostate [P] + SV radiation therapy [RT]) using intensity-modulated radiotherapy (IMRT) or external-beam RT (EBRT) with a high-dose rate (HDR) or a permanent prostate (radioactive seed) implant (PPI) boost.
I. Demonstrate that prophylactic WPRT improves biochemical control.
II. Distant metastasis (DM)-free survival.
III. Cause-specific survival (CSS).
IV. Compare acute and late treatment-adverse events between patients receiving NADT and WPRT versus NADT + P and SV RT.
V. Determine whether health-related quality of life (HRQOL), as measured by the Expanded Prostate Cancer Index Composite (EPIC), significantly worsens with increasing aggressiveness of treatment (i.e., Arm 2, NADT + WPRT). (closed to patient accrual 3/9/15)
VI. Determine whether more aggressive treatment (Arm 2, NADT + WPRT) is associated with a greater increase in fatigue (Patient-Reported Outcome Measurement Information System [PROMIS] Fatigue Short Form) from baseline to last week of treatment, and a greater increase in circulating inflammatory markers (interleukin [IL]-1, IL-1 receptor antagonist [ra], IL-6, tumor necrosis factor [TNF]-alpha, and C-reactive protein). (closed to patient accrual 3/9/15)
VII. Demonstrate an incremental gain in OS and CSS with more aggressive therapy that outweighs any detriments in the primary generic domains of HRQOL (i.e., mobility, self-care, usual activities, pain/discomfort, and anxiety/depression). (closed to patient accrual 3/9/15)
VIII. Determine whether changes in fatigue from baseline to the next three time points (week prior to RT, last week of treatment, and 3 months after treatment) are associated with changes in circulating cytokines, mood, sleep, and daily activities across the same time points.
IX. Collect paraffin-embedded tissue blocks, plasma, whole blood, and urine for planned and future translational research analyses.
OUTLINE: Patients are randomized to 1 of 2 treatment arms.
All patients receive neoadjuvant androgen-deprivation therapy comprising bicalutamide orally (PO) once daily (QD) or flutamide PO thrice daily (TID) for 6 months, and luteinizing hormone-releasing hormone (LHRH) agonist/antagonist therapy comprising leuprolide acetate, goserelin acetate, buserelin, triptorelin, or degarelix subcutaneously (SC) or intramuscularly (IM) every 1 to 3 months beginning 2 months prior to radiotherapy and continuing for 6 or 32 months. Radiotherapy begins within 8-10 weeks after beginning LHRH agonist/antagonist injection.
ARM I: Patients undergo high-dose radiotherapy of the prostate and seminal vesicles using IMRT* or 3D-conformal radiation therapy (3D-CRT)* QD, 5 days a week, for approximately 9 weeks. Patients may also undergo PPI brachytherapy or high-dose rate brachytherapy (iodine I 125 or palladium Pd 103 may be used as the radioisotope).
ARM II: Patients undergo WPRT* (3D-CRT or IMRT) QD, 5 days a week, for approximately 9 weeks. Patients may also undergo brachytherapy as in Arm I.
NOTE: * Patients undergoing brachytherapy implant receive 5 weeks of IMRT, 3D-CRT, or WPRT.
After completion of study treatment, patients are followed up every 3 months for 1 year, every 6 months for 3 years, and then yearly thereafter.
Pathologically (histologically or cytologically) proven diagnosis of prostatic adenocarcinoma within 180 days of registration at moderate- to high-risk for recurrence as determined by one of the following combinations:
Gleason score 7-10 + T1c-T2b (palpation) + prostate-specific antigen (PSA) < 50 ng/mL (includes intermediate- and high-risk patients)
Gleason score 6 + T2c-T4 (palpation) + PSA < 50 ng/mL OR Gleason score 6 + >= 50% (positive) biopsies + PSA < 50 ng/ml
Gleason score 6 + T1c-T2b (palpation) + PSA > 20 ng/mL
Patients previously diagnosed with low risk prostate cancer undergoing active surveillance who are re-biopsied and found to have unfavorable intermediate risk disease or favorable high risk disease according to the protocol criteria are eligible for enrollment within 180 days of the repeat biopsy procedure
History/physical examination (to include at a minimum digital rectal examination of the prostate and examination of the skeletal system and abdomen) within 90 days prior to registration
Clinically negative lymph nodes as established by imaging (pelvic and/or abdominal computed tomography [CT] or magnetic resonance [MR]), (but not by nodal sampling, or dissection) within 90 days prior to registration
Patients with lymph nodes equivocal or questionable by imaging are eligible if the nodes are =< 1.5 cm
No evidence of bone metastases (M0) on bone scan within 120 days prior to registration (sodium fluoride [NaF] positron emission tomography [PET]/CT is an acceptable substitute)
Equivocal bone scan findings are allowed if plain films (or CT or magnetic resonance imaging [MRI]) are negative for metastasis
