Clinical value of CD25/CD123 co-expression in acute myeloid leukemia patients.

BACKGROUND

This study aimed to assess the significance of combined expression of interleukin-2 receptor (CD25) and the interleukin-3 receptor (CD123) in acute myeloid leukemia (AML) patients.

METHODS

The expression of CD25 and CD123 on blast cells in bone marrow samples were identified by flowcytometry in 94 patients (⩽ 60 years old) with de novo acute myeloid leukemia (AML) treated at the Mansoura University Oncology Center (MUOC).

RESULTS

Of the 94 samples at diagnosis there were 17 (18.1%) CD25+/CD123+ (double positive) cases; 25 (26.6%) CD25+/CD123- (single positive); 32 (34.0%) CD25-/CD123+ (single positive) cases; 20 (21.3%). CD25-/CD123- (double negative). Most of the AML patients have double CD25+/CD123+ were significantly associated with poor and intermediate risk as compared to those associated with those in the good risk group (P= 0.005). The lowest induction of remission was recorded in AML patients have double CD25+/CD123+ expression as compared to the remaining AML patient group. Study the effect of these biomarkers on the overall survival reveal that AML patients exhibited double CD25+/CD123+ expression had significantly shorter overall survival as compared to negative ones.

CONCLUSION

Double CD25+/CD123+ co-expression in AML patients is a dismal prognostic marker and could be used as novel biomarker for risk stratification for AML patients.
