Antiandrogen Withdrawal in Treating Patients With Hormone-Refractory Prostate Cancer

Summary

RATIONALE: Antiandrogen withdrawal may be an effective treatment for prostate cancer. PURPOSE: Randomized phase III trial to study the effectiveness of ketoconazole and hydrocortisone for antiandrogen withdrawal in treating men with prostate cancer that is refractory to hormone therapy.
