 To determine the expression level of GATA-2 gene in acute myeloid leukemia with maturation (AML-M2) patients carrying AML1/ETO fusion gene.     ///    Bone marrow samples were collected from 23 patients with de novo adult AML-M2 carrying AML1/ETO fusion gene.     ///    "Therefore, AML-M2 patients with AML1/ETO fusion gene and high expression of GATA-2 would possibly benefit from additional treatments except for chemotherapy.. "    ///    [GATA-2 gene overexpression and its clinical significance in acute myeloid leukemia with AML1/ETO fusion gene]..     ///    High expression level of GATA-2 in AML-M2 patients with AML1/ETO is associated with high risk of relapse and poor prognosis.
