Аннотация
This study evaluated the clinical and prognostic significance of CD123 (IL3RA) expression in patients with acute leukemia. A total of 116 patients were included in this single-center observational study. CD123 expression in bone marrow blast cells was assessed by multiparameter flow cytometry and quantified as the percentage of CD123-positive cells. CD123 expression was detected in 79.3% of patients, with high expression (≥50%) observed in 68.1%. The highest levels were found in myeloid, myelomonocytic, and monoblastic variants.High CD123 expression was associated with increased bone marrow blast infiltration, aggressive disease course, primary resistance to therapy, and early relapse. A prognostic risk score incorporating CD123 expression, blast percentage, and leukemia subtype was developed and demonstrated acceptable predictive performance (AUC ≈0.74).The findings support the inclusion of CD123 in routine immunophenotyping panels and highlight its role as a prognostic biomarker for risk stratification and individualized therapeutic decision-making in acute leukemia.
