a study on Prostate Cancer
RATIONALE: Radiation therapy uses high-energy x-rays and other types of radiation to kill tumor cells and shrink tumors. Androgens can cause the growth of prostate cancer cells. Androgen-deprivation therapy may lessen the amount of androgens made by the body. It is not yet known whether radiation therapy is more effective with or without androgen-deprivation therapy in treating patients with prostate cancer.
PURPOSE: This randomized phase III trial is studying radiation therapy to see how well it works compared with radiation therapy given together with androgen-deprivation therapy in treating patients with prostate cancer.
A Phase III Prospective Randomized Trial of Dose-Escalated Radiotherapy With or Without Short-Term Androgen Deprivation Therapy for Patients With Intermediate-Risk Prostate Cancer
OUTLINE: This is a multicenter, dose-escalation study of radiotherapy. Patients are stratified according to number of risk factors (1 vs 2-3), comorbidity (ACE-27 grade ≥ 2 vs < 2), and radiotherapy (RT) modality (dose-escalated external-beam RT [EBRT] vs EBRT and low-dose rate brachytherapy boost vs EBRT and high-dose rate brachytherapy boost). Patients are randomized to 1 of 2 treatment arms.
After completion of study therapy, patients are followed up periodically.
