A Phase III Protocol of Androgen Suppression (AS) and 3DCTR/IMRT Vs AS and 3DCTR/IMRT Followed by Chemotherapy With Docetaxel and Prednisone for Localized, High-Risk, Prostate Cancer

Trial Conditions
  • Prostate Cancer
What is the purpose of this trial?

RATIONALE: Androgens can cause the growth of prostate cancer cells. Hormone therapy using drugs, such as leuprolide, goserelin, flutamide, or bicalutamide, may fight prostate cancer by lowering the amount of androgens the body makes. Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as docetaxel and prednisone, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether giving hormone therapy and radiation therapy together with chemotherapy is more effective than giving hormone therapy together with radiation therapy in treating prostate cancer. PURPOSE: This randomized phase III trial is studying hormone therapy and radiation therapy followed by docetaxel and prednisone to see how well it works compared to hormone therapy and radiation therapy in treating patients with localized prostate cancer.
