[Immunophenotypic Analysis of Patients with CD56⁺ Acute Myeloid Leukemia].

To explore the immunophenotype characteristics of newly diagnosed patients with CD56⁺ acute myeloid leukemia (AML).Combining with cytomorphology, four-color flow cytometry was used to analyze the immunophenotype of 342 AML patients with CD56⁺ or CD56⁻.In 342 AML patients, the CD56⁺ expression was found in 83 AML patients who accounted for 24.27% and included 10 cases of M1, 45 cases of M2, 5 cases of M3, 6 cases of M6 and 17 cases of M5. The statistical analysis showed that there was statistical difference between CD56⁺ and CD11b⁺ patients (P 0.05).AML with only CD56 positive always has poor prognosis, thus the prognosis of patients with CD56⁺ AML accompanied by other antigens still needs more research.
