Immunophenotypic characterization of the leukemic cells has been widely used as a tool for diagnosis, classification and prognosis of leukaemia. Several studies have identified a relationship between AML prognosis and antigens such as CD7, CD9, CD11b, CD13, CD14, CD15, CD33, CD34, and CD56, though some other studies report conflicting results.

The results of this study were compared with other clinical and biological features. More practically, and although the relationships demonstrated only represent a fraction of homogeneous immunophenotypic subgroups, identification of such immunophenotypic features should prompt careful karyotypic examination, eventually using molecular biology analysis on non-growing cells. Comparing cases with immunophenotypic dissimilarities to those with cytogenetic differences, no distinct patterns of association were identified. Last, the positive rate of Ki-67 expression in ANKL cells was generally high.
