- Radiation Therapy Oncology Group
- Brief Summary
RATIONALE: Androgens can stimulate the growth of prostate cancer cells. Drugs such as luteinizing hormone-releasing hormone agonist, flutamide, and bicalutamide may stop the adrenal glands from producing androgens. Drugs used in chemotherapy work in different ways to stop tumor cells from dividing so they stop growing or die. Combining hormone therapy with chemotherapy may kill more tumor cells. It is not yet known whether chemotherapy given at the same time as hormone therapy is more effective than chemotherapy given after hormone therapy in treating prostate cancer.
PURPOSE: Randomized phase III trial to compare the effectiveness of chemotherapy given at the same time as hormone therapy with that of chemotherapy given after hormone therapy in treating patients who have prostate cancer.
- Detailed Description
OBJECTIVES:
Primary
* Compare the survival of patients with high-risk hormone-naive prostate cancer treated with androgen blockade with concurrent chemotherapy vs delayed chemotherapy.
Secondary
* Compare biochemical control in patients treated with these regimens.
* Determine the toxicity of these regimens in these patients.
* Compare the time to clinical failure, as measured by progression on bone scan or CT scan or a prostate-specific antigen (PSA) doubling time of ≤ 32 weeks, in patients treated with these regimens.
OUTLINE: This is a randomized, multicenter study. Patients are stratified according to prior therapy (surgery vs radiotherapy and/or brachytherapy vs both), original combined Gleason score (6 vs 7 vs 8-10), and prior vaccine therapy (yes vs no). Patients are randomized to 1 of 2 treatment arms.
* Arm I: Patients receive androgen blockade (AB) comprising a luteinizing-hormone releasing-hormone agonist continuously and oral flutamide or oral bicalutamide once daily for at least 1 month. Within 4 weeks of initiation of AB, patients begin chemotherapy. Patients receive 1, and only 1, of the following chemotherapy regimens:
* Regimen A: Patients receive oral estramustine 3 times daily on days 1-5 and docetaxel IV on day 3. Treatment repeats every 21 days for 4 courses in the absence of disease progression or unacceptable toxicity.
* Regimen B: Patients receive oral estramustine 3 times daily on days 1-5 and paclitaxel IV on days 3, 10, 17, 24, 31, and 38. Treatment repeats every 56 days for 4 courses in the absence of disease progression or unacceptable toxicity.
* Regimen C: Patients receive oral ketoconazole 3 times daily on days 1-7, 15-21, and 29-35; doxorubicin IV on days 1, 15, and 29; vinblastine IV on days 8, 22, and 36; and oral estramustine 3 times daily on days 8-14, 22-28, and 36-42. Treatment repeats every 56 days for 4 courses in the absence of disease progression or unacceptable toxicity.
* Regimen D: Patients receive oral estramustine 3 times daily on days 1-4 and docetaxel IV over 1 hour on days 3, 10, and 17. Treatment repeats every 28 days for 4 courses in the absence of disease progression or unacceptable toxicity.
* Regimen E: Patients receive docetaxel IV on day 1. Treatment repeats every 21 days for 4 courses in the absence of disease progression or unacceptable toxicity.
* Regimen F: Patients receive docetaxel IV on days 1, 8, and 15. Treatment repeats every 28 days for 4 courses in the absence of disease progression or unacceptable toxicity.
* Regimen G: With approval from the protocol chair, patients may receive a regimen that has been demonstrated in a published phase II study to have at least a 50% response rate as measured by PSA decrease from baseline over 2 measurements 28 days apart or a decrease in measurable soft tissue disease by 50% in 2 dimensions.
* Arm II: Patients receive AB as in arm I. Patients continue with AB until clinical failure, at which time patients receive chemotherapy as in arm I. Patients who have a response may continue to receive chemotherapy beyond 4 courses.
Patients are followed every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter.
PROJECTED ACCRUAL: A total of 1,050 patients will be accrued for this study within 4-6 years.
