Leuprolide acetate (a luteinizing hormone releasing hormone (LHRH) agonist) and Bicalutamide (an anti-androgen) are hormonal agents which are commonly used to reduce testosterone blood level for prostate cancer treatment. Intensity modulated external beam radiotherapy is a standard treatment for localized prostate cancer. Previous studies have shown that combining hormonal therapy and radiation is more effective than radiation alone. Unfortunately, significant percentages (50-75%) of patients still relapse. Sorafenib reduces the growth of cancer cells and has proven effective in the treatment of solid tumors including kidney and liver cancer. This drug is approved by the FDA for treatment kidney and liver cancer. The study investigators believe that adding sorafenib to standard treatment, comprising hormonal therapy and radiation, might be more effective then standard hormonal therapy.
