Isotretinoin, Interferon Alfa-2b, Docetaxel, and Estramustine in Treating Patients With Metastatic Prostate Cancer That Did Not Respond to Hormone Therapy
A Phase II Trial of 13-Cis Retinoic Acid, Alpha Interferon, Taxotere, and Estramustine (R.I.T.E.) for the Treatment of Hormone Refractory Prostate Cancer
RATIONALE: Isotretinoin may help prostate cancer cells become more like normal cells, and to grow and spread more slowly. Interferon alfa-2b may interfere with the growth of tumor cells. Drugs used in chemotherapy, such as docetaxel and estramustine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving isotretinoin and interferon alfa-2b together with docetaxel and estramustine may kill more tumor cells.
PURPOSE: This phase II trial is studying how well giving isotretinoin and interferon alfa-2b together with docetaxel and estramustine works in treating patients with metastatic prostate cancer that did not respond to hormone therapy.
Study Overview

Conditions
Detailed Description
OBJECTIVES:
Primary
- Determine the response rate, in terms of change in measurable disease or prostate-specific antigen levels, in patients with hormone-refractory metastatic prostate cancer treated with isotretinoin, recombinant interferon alfa-2b, docetaxel, and estramustine phosphate sodium.
Secondary
- Determine the effect of this regimen on bcl-2 family proteins in peripheral blood mononuclear cell samples obtained from these patients.
OUTLINE: Patients receive oral isotretinoin once daily on days 1-4, recombinant interferon alfa-2b subcutaneously once daily on days 1-4, oral estramustine phosphate sodium three times daily on days 1-5, and docetaxel IV over 1 hour on day 2. Treatment repeats every 21 days in the absence of disease progression or unacceptable toxicity.
Peripheral blood mononuclear cells are acquired via blood draw at baseline and on days 2, 3, or 4 and analyzed for bcl-2 protein by IHC and electrophoresis.
PROJECTED ACCRUAL: A total of 40 patients will be accrued for this study.
