Hormone Suppression and Radiation Therapy for 6 Months With/Without Docetaxel for High Risk Prostate Cancer

Docetaxel Plus 6-month Androgen Suppression and Radiation Therapy Versus 6-month Androgen Suppression and Radiation Therapy for Patients With High Risk Localized or Locally Advanced Prostate Cancer: A Randomized Controlled Trial

This randomized study is looking at the benefits of using docetaxel (chemotherapy) added to one of the standard treatments (radiation and hormones) for men with high-risk prostate cancer.

Radiation therapy plus six months of hormone therapy is one standard way of treating men with high-risk prostate cancer. In this study, we want to see whether or not adding the chemotherapy drug docetaxel (Taxotere)will make this treatment more effective. Docetaxel has shown a benefit in median survival when given to men who have become resistant to hormonal therapy and in men who have metastatic prostate cancer (spread to other areas of the body).
