[FLT3 gene overexpression and its clinical significance in acute myeloid leukemia with AML1/ETO fusion gene positive]..     ///    " This study was aimed to investigate the expression levels of FLT3 gene in AML-M2 patients carrying AML1/ETO fusion gene, and analyze its relation with clinical and laboratorial features and prognosis. "    ///    It is concluded that FLT3 gene high expression in AML-M2 patients with AML1/ETO(+) have a higher rate of relapse and hence poor prognosis.     ///    RQ-PCR method was used to detect the expression level of FLT3 in bone marrow of 21 AML-M2 patients with AML1/ETO(+).
