ABSTRACT
OBJECTIVE@#To detect the expression of miR-146a in patients with AML, and to evaluate the relationship between miR-146a expression level and clinical characteristics, treatment response, EFS and OS.@*METHODS@#154 patients with newly diagnosed AML were enrolled in AML group, 50 controls (patients with thrombocytopenic purpura or voluntary donor of bone marrow) were enrolled in control group. The miR-146a expression levels in bone marrow mononuclear cells was detected by RT-PCR between 2 group. AML patients were treated with chemotherapeutic drugs, and their clinical response and survivals were assessed.@*RESULTS@#The expression level of MiR-146a in AML group was significantly lower than that in control group. The ROC showed that miR-146a could distinguish the patients in AML and control group better (area under curve 0.819 (95%CI 0.761-0.877). Meanwhile, the proportion of good and moderate good prognosis (P<0.001), proportion of WBC count ≤15.2×10/L (P<0.05), CR rate (P<0.05), EFS (P<0.01) and OS (P<0.01) in patients with high miR-146a expression were higher than those in patients with low miR-146a expression. Cox's model showed that miR-146a expression level positively realated with incressed EFS and OS.@*CONCLUSION@#MiR-146a is downregulated in AML patients, which might be served as a biomarker for predicting risk and prognosis of AML patients.
