Docetaxel will be given intravenously on day 2. These two drugs will be repeated every 3 weeks for a total of 4 cycles (12 weeks). * Patients will also take dexamethasone for three days at the beginning of each cycle to help decrease the risk of side effects. * Patients will also take coumadin every day for three months while on the chemotherapy to reduce the risk of blood clots. * After 12 weeks the chemotherapy phase will be completed and patient will start on the hormone therapy part of the treatment.
