OBJECTIVE@#To investigate the expression of CD73 in acute myeloid leukemia (AML) patients with NPM1 mutant and wild-type, and to evaluate the therapeutic efficacy and prognosis of CD73 to the AML patients.@*METHODS@#160 patients with AML treated in our hospital from June 2015 to June 2019 were enrolled, and 40 non-AML bone marrow samples from healthy people were selected as controls during the same period. The expression of CD73 in healthy people, NPM1 mutation and NPM1 wild-type AML patients were compared, and the relationship between the expression of CD73 and its clinicopathological characteristics, as while as efficacy in AML patients were analyzed. The patients were followed up, and the influence of CD73 to the prognosis of different AML patients was analyzed.@*RESULTS@#The positive expression rate of CD73 in AML patients (23.75%) was significantly higher than that in the healthy control group (0.62%), and the positive expression rate of CD73 in AML patients with NPM1 mutation (74.75%) was significantly higher than that with NPM1 wild-type (25.51%) (both P<0.001). AML patients with CD73 positive expression was associated with age, FAB typing, disease risk classification, and NPM1 gene mutation (both P<0.05). The overall survival rate of AML patients with NPM1 gene mutation was 75.98%, which was significantly higher than the patients with NPM1 wild-type (34.68%)(P<0.001), the median survival time of AML patients with NPM1 gene mutation in the CD73@*CONCLUSION@#The expression of CD73 was increased in AML patients with NPM1 gene mutation, and CD73 showed different prognostic significance in AML patients with different NPM1 gene mutation. The combination of clinicopathologic features, CD73 expression and NPM1 gene in AML patients is helpful to determine their prognosis and guide the formulation of relevant treatment plans.
