Study Summary

RATIONALE: Selenomethionine may slow the growth of prostate cancer. Testosterone can cause the growth of prostate cancer cells. Finasteride may fight prostate cancer by lowering the amount of testosterone the body makes. Giving selenomethionine together with finasteride before surgery or radiation therapy may be an effective treatment for prostate cancer. PURPOSE: This randomized phase II trial is studying how well selenomethionine and finasteride work when given before surgery or radiation therapy in treating patients with stage I or stage II prostate cancer.

Primary Outcome

Compare PSA levels with Finasteride Placebo + Selenium Placebo group (Arm C). The Wilcoxon Rank Sum Test was used to test the difference of PSA levels of Arm A, Arm B, Arm D with Arm C.
