Brief summary
This phase I trial is studying the side effects and best dose of docetaxel when given with radiation therapy and hormone therapy in patients with locally advanced prostate cancer.
Detailed description
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. Radiation therapy uses high energy x-rays to kill tumor cells. Docetaxel may also make tumor cells more sensitive to radiation therapy. Androgens can cause the growth of prostate cancer cells. Drugs, such as leuprolide, goserelin, or bicalutamide, may stop the adrenal glands from making androgens. Giving chemotherapy with radiation therapy and hormone therapy may kill more tumor cells.
Interventions
Bicalutamide will be administered for approximately 28 months: prior to radiotherapy (2 months), during radiotherapy (2 months), and after radiotherapy (24 months)
Docetaxel will be administered weekly during radiotherapy. The docetaxel dose will be escalated as part of the study. Dose levels are: 10mg/m2; 15 mg/m2; 20 mg/m2 and 25 mg/m2
A GnRH analog (goserelin acetate, leuprolide acetate) will be administered for approximately 28 months: prior to radiotherapy (2 months), during radiotherapy (2 months), and after radiotherapy (24 months) Bicalutamide will be administered for approximately 28 months: prior to radiotherapy (2 months), during radiotherapy (2 months), and after radiotherapy (24 months)
External beam photon radiotherapy utilizing 3-D-conformal or intensity modulated radiotherapy (IMRT) shall be used to deliver 77.4 4 Gy in 43 fractions of 1.8 Gy fractions.

| Measure | Time frame | Description |
|---|---|---|
| Maximum tolerated dose (MTD) of Taxotere with radiation therapy and hormonal therapy | 57 days | To determine the MTD of Taxotere with radiation therapy and hormonal therapy in patients with high risk locally advanced adenocarcinoma of the prostate. The dose limiting toxicity (CLT) period for determining the MTD is 57 days. |
