Summary
Brief summary (as posted)
The goal of this clinical research study is to see if Gleevec, known as imatinib mesylate (STI571), can improve the disease condition in patients with hypereosinophilic syndrome, polycythemia vera, atypical CML or CMML with PDGF-R fusion genes, or mastocytosis.

- description
- Acute myeloid leukemia (AML), Myelodysplastic Syndromes (MDS): CR=Normalization peripheral blood \& bone marrow with 5% or less blasts; normo- or hypercellular marrow; Absolute Neutrophil Count (ANC) \> 1.0 x 10\^9/L, \& platelet count \>100 x 10\^9/L; or CR marrow=As per CR but platelet count \< 100 x 10\^9/L. Agnogenic myeloid metaplasia (AMM) \& CMML: CR=Absence of signs/symptoms of disease; White blood count between 1 to 10 x 10\^9/L with no peripheral blasts, promyelocytes, or myelocytes and normalization of bone marrow (\< 5% blasts in normocellular or hypercellular marrow) for 4+ weeks. PV: CR=normalization of hemoglobin/hematocrit without need for phlebotomies, disappearance all signs/symptoms of disease. HES: CR=disappearance of eosinophilia (\</=10%), disappearance signs/symptoms of disease. Mastocytosis: CR=disappearance of mast cell infiltrates in affected organs, decrease of serum tyrptase levels to \<20 ng/ml, \& disappearance of SM-associated organomegaly.
