| Purpose: |
|
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.

| Study summary: |
|
OBJECTIVES:
Primary
- Compare the relative efficacy, in terms of overall survival, of the combination of
androgen suppression and radiotherapy versus androgen suppression and radiotherapy
followed by docetaxel and prednisone in patients with localized, high-risk prostate
cancer.
Secondary
- Compare the disease-free survival and incidence of adverse events in patients treated
with these regimens.
- Compare the biochemical control, local control, and freedom from distant metastases in
patients treated with these regimens.
- Determine the validity of prostate-specific antigen (PSA)-defined endpoints as a
surrogate for overall survival of patients treated with these regimens.
- Compare the time interval between biochemical failure and distant metastases with
respect to testosterone level in patients treated with these regimens.
OUTLINE: This is an open-label, randomized, multicenter study. Patients are stratified
according to risk group.
- Arm I: Patients receive androgen suppression therapy comprising luteinizing
hormone-releasing hormone (LHRH) agonist (e.g., leuprolide acetate, goserelin,
buserelin, or triptorelin) and oral antiandrogen (i.e., oral flutamide 3 times daily for
2 months or oral bicalutamide once daily for 2 months). Beginning at week 8, patients
undergo radiotherapy 5 days a week for approximately 8 weeks. Antiandrogen therapy is
discontinued at completion of radiotherapy, but LHRH agonist therapy continues for 20
months.
- Arm II: Patients receive androgen suppression therapy and undergo radiotherapy as in arm
I. Beginning 4 weeks after completion of radiotherapy, patients receive docetaxel IV
over 1 hour on day 1 and oral prednisone daily on days 1-21. Treatment repeats every 21
days for up to 6 courses in the absence of disease progression or unacceptable toxicity.
Patients continue LHRH agonist therapy as in arm I. After completion of study treatment,
patients are followed every 3 months for 2 years, every 6 months for 3 years, and then
annually thereafter.
PROJECTED ACCRUAL: A total of 600 patients will be accrued for this study. |
