Azacitidine Plus Amifostine in Treating Patients With Myelodysplastic Syndrome

Study Overview
=================
Brief Summary
-----------------
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Amifostine may improve blood counts in patients with myelodysplastic syndrome. Combining azacitidine with amifostine may kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of azacitidine plus amifostine in treating patients who have myelodysplastic syndrome.

Detailed Description
-----------------
OBJECTIVES: I. Determine the response rate to azacitidine plus amifostine in patients with myelodysplastic syndromes. II. Evaluate the toxicity of this treatment regimen in these patients. III. Assess the rate of progression to acute myeloid leukemia and overall survival in these patients treated with this regimen. IV. Evaluate the relationship between response status and cytogenetics, FAB class, ras mutations, and the presence of nonclonal hematopoiesis with this treatment regimen in these patients. V. Assess the effect of this treatment regimen on the number of bone marrow hematopoietic progenitor cells in these patients. VI. Evaluate neutrophil adhesion and chemotaxis in these patients before and after this treatment regimen. OUTLINE: Patients receive amifostine IV over 1-3 minutes on days 8, 10, 12, 15, 17, 19, 22, 24, and 26 plus azacitidine subcutaneously on days 1-7. Treatment repeats every 28 days for 4 courses. Patients who achieve complete remission receive an additional 3 courses, and patients who achieve hematologic improvement or partial remission continue treatment until disease progression or unacceptable toxicity. Patients are followed until death. PROJECTED ACCRUAL: A total of 17-32 patients will be accrued for this study within approximately 2 years.
