This study was aimed to investigate laboratorial characteristics of immunophenotyping and concurrent karyotypic aberrations in acute myeloid leukemia with t(8;21)(q22;q22). A total number of 47 AML patients with t(8;21) were enrolled in this study and immunophenotypic antigens were detected by multiparameter flow cytometry. The results indicated that the additional karyotypic aberrations were found in 21 out of 47 AML patients with t(8;21) (q22;q22 (44.68%), single karyotypic aberration was observed in 26 out of 47 AML patients with t(8;21) (q22;q22) (55.32%). The positive rate of stem/progenitor cell markers of CD34, CD117 and HLA-DR were 87.2%, 97.9% and 95.7% respectively. Myeloid markers of CD13 and CD33 were 93.6% and 87.2%, and there were nearly no expression of T lineage antigens (CD2, CD3, CD5 and CD7) detected in t(8;21)-AML. CD19, one of a pan-B markers was found in 66.0% of all 47 t(8;21)-AML patients as well as CD56(66.7%), which was significant higher than other B lineage antigens (CD20 and CD22). It is concluded that AML with t(8;21) displays an exclusive immunophenotyping with significantly high expression of CD19 and CD56 as well as precursor cell markers (CD34, CD117 and HLA-DR) and combination detection of CD34/CD19/CD56 may become a predictive indicator of t(8;21) (q22;q22) cytogenetic abnormality.
