Abstract:
ObjectiveTo explore the clinical significance of fms-like tyrosine kinase3(FLT3) expression in evaluation prognosis of acute myeloid leukemia(AML) prognosis.Methods50 patients with AML were selected.AML patients with normal karyotype were 20 cases,the abnormal karyotype were 30 cases.3ml bone marrow before themotherapy was aspirated respectively,and the FLT3 gene expression in leukemia cells was detected with polyenzyme chain react(PCR).ResultsThe FLT3 expression rate in AML patients with normal karyotype was 5.0％,and was 26.7％ in AML patients with abnormal karyotype,33.3％ in AML patients with refractory-relapse,and 4.5％ in AML patients with continue remission.The FLT3 expression rate was related with high leukemia cells percentage in bone marrow and high blood cells count in peripheral blood,and was not related with Franch America British(FAB) classification.The free-disease survival(FDS) and overall survived(OS) was shorter in FLT3 expression AML patients than that in no FLT3 expression AML patients.There was a statistical significance between the former and the latter( x2 =4.17,P ＜0.05 ).Conclusion FLT3 was a kind of worse factor in AML patients prognosis,and could guide clinical individual treatment in AML.
