Abstract:

Objective To analyze the relationship between FANCF/BRCA1 protein expression and treatment response in patients with acute myeloid leukemia(AML). Methods Totally,120 patients with AML in the First Hospital of Qinhuangdao from February 2018 to January 2022(observation group) were enrolled,and 48 patients with non-malignant blood diseases who underwent bone marrow biopsy were enrolled as control group. The mononuclear cells in the bone marrow fluid of all the subjects were extracted,the FANCF/BRCA1 protein expression was analyzed semi-quantitatively by western blotting,and the difference of FANCF/BRCA1 protein expression between observation group and control group was compared. The patients with AML were treated with induction therapy,the complete remission rate was recorded,and the relationship between FANCF/BRCA1 protein expression and therapeutic response was analyzed. Results The expression of FANCF/BRCA1 protein in observation group was lower than that in control group(P<0.001). Among the 120 AML patients,62 cases had high expression of FANCF/BRCA1 protein(≥0.79),and 58 cases had low expression(<0.79). The expression of FANCF/BRCA1 protein was correlated with hemoglobin and platelet count in AML patients(P<0.05). The expression of FANCF/BRCA1 protein was positively correlated with the therapeutic response of AML patients(r=0.548,P<0.05). The complete response rate of FANCF/BRCA1 high expression group(82.26%) was higher than that of FANCF/BRCA1 low expression group(56.90%)(P<0.05). Conclusions The expression of FANCF/BRCA1 protein is positively correlated with the therapeutic response of AML patients,which can be used to evaluate the therapeutic response of patients.
