RATIONALE: Radiation therapy uses high-energy x-rays and other sources of radiation to kill tumor cells. It is not yet known which radiation therapy regimen is more effective in treating prostate cancer.
PURPOSE: This randomized phase III trial is comparing two different regimens of radiation therapy to see how well they work in treating patients with stage II or stage III prostate cancer.
Condition or disease | Intervention/treatment | Phase |
---|---|---|
Prostate Cancer | Radiation: radiation therapy | Phase 3 |
OBJECTIVES:
- Compare the efficacy of conventional intensity-modulated radiotherapy (IMRT) vs hypofractionated IMRT, in terms of freedom from biochemical failure in men with intermediate- to high-risk prostate cancer.
- Compare the local control, freedom from distant metastasis, and overall survival of patients treated with these regimens.
- Determine local failure, using biopsy of the prostate, when objective tests (prostate-specific antigen, ultrasound, and digital rectal exam) suggest relapse in these patients.
- Compare the extent of disease eradication using biopsy of the prostate at 2 years after therapy in these patients.
- Compare the quality of life of patients treated with these regimens.
- Determine the impact of these regimens on patient preferences and utilities.
OUTLINE: This is a randomized study. Patients are stratified according to pretreatment prostate-specific antigen (no greater than 10 ng/mL vs greater than 10 to 20 ng/mL vs greater than 20 ng/mL), Gleason score (5-7 vs 8-10), and risk status (high risk vs intermediate risk). Patients are randomized to 1 of 2 treatment arms.
- Arm I: Patients undergo conventional intensity-modulated radiotherapy (IMRT) 5 days a week for 7.5 weeks in the absence of disease progression or unacceptable toxicity.
- Arm II: Patients undergo hypofractionated IMRT 5 days a week for 5 weeks in the absence of disease progression or unacceptable toxicity.
Patients with high-risk disease also undergo androgen deprivation therapy for 2 years.
Quality of life is assessed at baseline, every 6 months for 1 year, and then annually for 4 years.
Patients are followed at 3 months, every 6 months for 2 years, and then annually thereafter.
PROJECTED ACCRUAL: A total of 300 patients (150 per treatment arm) will be accrued for this study within 3 years.
