Trial Summary

What is the purpose of this trial?

RATIONALE: Androgens can cause the growth of prostate cancer cells. Drugs, such as steroid 17alpha-monooxygenase TAK-700, when used with other hormone therapy, may lessen the amount of androgens made by the body. Radiation therapy uses high energy x rays to kill tumor cells. This may be an effective treatment for prostate cancer when combined with hormone therapy. Studying quality-of-life in patients having cancer treatment may help identify the intermediate- and long-term effects of treatment on patients with prostate cancer. PURPOSE: This randomized phase III trial is studying the use of hormone therapy, including TAK-700, together with radiation therapy in treating patients with prostate cancer.
