Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

RATIONALE: Eating a diet high in soy foods may slow the progression of some types of cancer. Isoflavones are compounds found in soy food that may slow the growth of prostate cancer cells and prevent further development of prostate cancer. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving isoflavones together with radiation therapy may be an effective treatment for prostate cancer. PURPOSE: This randomized phase II trial is studying the side effects and how well giving isoflavones together with radiation therapy works in treating patients with localized prostate cancer.
