About
RATIONALE: Drugs used in chemotherapy, such as docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Androgens can cause the growth of prostate cancer cells. Antihormone therapy, such as leuprolide, may lessen the amount of androgens made by the body. Radiation therapy uses high energy x-rays to kill tumor cells. Giving docetaxel together with androgen ablation therapy and external-beam radiation therapy may kill more tumor cells.
PURPOSE: This phase I/II trial is studying the side effects and best dose of docetaxel when given together with androgen ablation therapy and external-beam radiation therapy and to see how well they work in treating patients with high-risk localized prostate cancer.

OBJECTIVES:
Primary
Secondary
OUTLINE: This is a multicenter, open-label, dose-escalation study of docetaxel.
Cohorts of 3-6 patients receive escalating doses of docetaxel until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.
After completion of study treatment, patients are followed every 3 months.

Patient must be willing to consent to using effective contraception while on treatment and for at least 3 months thereafter.
