Abstract
Background: FLT3 is mutated in about 1/3 of acute myelogenous leukemia (AML) patients. The aim of the present study was to report the prevalence of FLT3 mutations and comparison with prognostic factors in AML patients in the Northeastern of Iran. Materials and Methods: This cross-sectional study concerned 100 AML cases diagnosed based on bone marrow aspiration and peripheral blood. DNA for every AML patient was extracted and underwent PCR with FLT3-ITD primers. Results: The mean age at diagnosis was 28.5 years (range, 1-66 years), 52 patients (52%) being male. Out of 100 AML patients, 21 (21%) had FLT3 mutation, (17 with FLT3- ITD, 81%, and 4 with FLT3-D825, 19%). Of the 21, 14 (66.7%) had heterozygous mutation. There was no significant difference between age, sex and organomegaly between patients with FLT3 mutation versus FLT3 wild-type. Conclusions: Our frequency of FLT3 is in line with earlier fidnings of approximately 20 to 30% and also the prevalence of FLT3-ITD is more than FLT3-D35 mutation. There was no significant difference between prognostic factors (age and sex) in the patients with FLT3 mutation versus FLT3 wild-type. The prevalence of FLT3 heterozygous mutations is more that homozygous mutations in AML patients.
