    Abstract:
    This study was designed to assess the significance of interleukin-2 receptor (CD25) and inteleukin-3 receptor (CD123) expression in cytogenetically normal acute myeloid leukemia (CN-AML) patients. The current study includes 80 CN-AML (≤ 60 years) before the start of therapy. Blast cells expression for CD25 and CD123 were identified by flowcytometry in fresh bone marrow samples. CD25+/CD123-; CD25-/CD123+. CD25+/CD123+, CD25-/CD123- expression were as follow: 10/80 (12.5%); 18/80 (22.5%); 17/80; (21.25%), 35/80 (43.5%) respectively. The total CD25 expression was detected in 27/80 (33.75%), and CD123 expression was detected in 35/80 (43.75%%). CN-AML patients showed CD25+/CD123+ co-expression had the lowest induction remission rate and the shortest overall survival as compared to those lack co-expressions (P <0.01; P = 0.023 respectively). Also, there is strong positive association between CD25+/CD123+ co-expression and FLT3 mutations (P<0.001) and negative one with NPM1 mutation (P<0.001). In conclusion: CD25+/CD123+ co-expression in CN-AML patients define a subgroup of patients with adverse outcome. Identification of CD25/CD123 expression in CN-AML patents at diagnosis could be included in risk stratification. There is strong association between CD25+/CD123+ positive expression and FLT3 mutations.
