Abstract
Background: Aberrant expression of cluster differentiation (CD) antigen marker is associated with poor outcome of acute leukaemia. Objective: Aim of this study is to determine the frequency and pattern of aberrant expression of CD markers in acute myeloid leukaemia patients in Bangladesh. Methods: This retrospective data analysis was conducted in the Department of Haematology, Bangabandhu Sheikh Mujib Medical University (BSMMU) to assess the frequency of aberrant CD antigen expression in acute myeloid leukaemia from October 2016 to September 2017. During this period, we did one hundred flow cytometry of acute leukaemia patients and among them we found 48 acute myeloid Leukaemia (AML) who were included in this study. Result: Mean age of patients was 35 years (SD +14 years; Rang 3 to 50 years) with male: female ratio of 0.92. Four colour flow cytometry was done on fresh bone marrow aspirates and peripheral blood. Among 48 AML patients, aberrant CD expression was observed in 58% cases. CD5 and cCD79a lymphoid markers were seen to be expressed in 32% cases of AML. Aberrant cCD3 and CD7 were expressed in 29% and 25% cases respectively and aberrant CD10, CD19, cCD22 were expressed in 11%, 3%, 3% cases acute myeloid leukaemia patients respectively. Conclusion: Aberrant CD antigen expression is not uncommon in AML patients of Bangladeshi population that may adversely affect the treatment outcome of the disease.
