Paclitaxel, Topotecan, and Estramustine in Treating Patients With Metastatic Hormone-Refractory Prostate Cancer
Phase II Study of the Activity of Weekly Paclitaxel, Topotecan Plus Oral Estramustine Phosphate in Metastatic Hormone-Refractory Prostate Carcinoma
RATIONALE: Drugs used in chemotherapy, such as paclitaxel, topotecan, and estramustine, work in different ways to stop tumor cells from dividing so they stop growing or die. Giving more than one chemotherapy drug may kill more tumor cells.
PURPOSE: This phase II trial is studying how well giving paclitaxel, topotecan, and estramustine together works in treating patients with metastatic hormone therapy-refractory prostate cancer.
연구 개요
상세 설명
OBJECTIVES:
Primary
- Determine the objective response rate in patients with metastatic hormone-refractory prostate cancer treated with paclitaxel, topotecan, and estramustine.
- Determine the progression-free and overall survival of patients treated with this regimen.
- Determine the toxic effects of this regimen in these patients.
- Determine the pharmacokinetics of this regimen in these patients.
Secondary
- Determine the frequency and number of circulating tumor cells in patients before and after treatment with this regimen and at disease progression.
- Determine the microtubule morphology, β-tubulin isotype pattern, apoptotic markers, and metaphase chromosome alignment in circulating tumor cells in patients before and after treatment with this regimen and at disease progression.
OUTLINE: Patients receive paclitaxel IV over 1 hour on days 1, 8, and 15; topotecan IV over 30 minutes on days 2, 9, and 16; and oral estramustine twice daily on days 1 and 2 of course 1 and on days 0-2, 7-9, and 14-16 of all subsequent courses. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
PROJECTED ACCRUAL: A total of 18-38 patients will be accrued for this study.

DISEASE CHARACTERISTICS:
Histologically confirmed adenocarcinoma of the prostate gland
- Progressive metastatic disease (e.g., bone, pelvic mass, lymph node, liver or lung metastases)
- Radiologic evidence of hydronephrosis alone dose not constitute metastatic disease
Failed prior primary hormonal therapy (e.g., estrogen therapy, luteinizing hormone-releasing hormone blocker and flutamide) or bilateral orchiectomy
- Patients previously treated with flutamide or bicalutamide must have evidence of disease progression i.e., increasing Prostate-Specific Antigen (PSA)
- PSA level ≥ 10 ng/mL if bone metastases only are present (i.e., lacking measurable soft tissue disease)
- No elevated serum acid phosphatase or PSA level as the only evidence of disease
- No carcinomatous meningitis or brain metastases
