Abstract:

Objective To analyze the expression of core-binding factor acute myeloid leukemia(CBF-AML) associated with KIT mutation in children and its relationship with clinical characteristics and prognosis. Methods Totally,72 newly diagnosed children with CBF-AML were enrolled from the Children's Hospital of Zhengzhou University from February 2014 to August 2022,and the clinical data of 72 children with CBF-AML were collected. According to the results of cytogenetic analysis,they were classified into RUNX1-RUNX1T1 group(60 cases) and CBFβ-MYH11 group(12 cases). They were classified into KIT positive group(31 cases) and KIT negative group(41 cases) according to the KIT mutation. The clinical characteristics and prognosis of KIT positive group and KIT negative group were compared. Results There was no statistical significance in gender,age,newly diagnosed white blood cell count,proportion of newly diagnosed peripheral blood and bone marrow blast cells,extramedullary leukemia,complete remission(CR) in the first course of treatment,5-year event-free survival and 5-year overall survival between KIT positive and KIT negative groups(P>0.05). Conclusions KIT mutation has no significant effect on the clinical manifestations and prognosis of children with CBF-AML.
