There have been conflicting results regarding a correlation between CD133 expression and disease outcome. To assess CD133 expression in patients with acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) and to evaluate its correlation with the different clinical and laboratory data as well as its relation to disease outcome, the present study included 60 newly diagnosed acute leukemic patients; 30 ALL patients with a male to female ratio of 1.5:1 and their ages ranged from 9 months to 48 years, and 30 AML patients with a male to female ratio of 1:1 and their ages ranged from 17 to 66 years. Flow cytometric assessment of CD133 expression was performed on blast cells. In ALL, no correlations were elicited between CD133 expression and some monoclonal antibodies, but in AML group, there was a significant positive correlation between CD133 and HLA-DR, CD3, CD7 and TDT, CD13 and CD34. In ALL group, patients with negative CD133 expression achieved complete remission more than patients with positive CD133 expression. In AML group, there was no statistically significant association found between positive CD133 expression and treatment outcome. The Kaplan-Meier curve illustrated a high significant negative correlation between CD133 expression and the overall survival of the AML patients. CD133 expression is an independent prognostic factor in acute leukemia, especially ALL patients and its expression could characterize a group of acute leukemic patients with higher resistance to standard chemotherapy and relapse. CD133 expression was highly associated with poor prognosis in acute leukemic patients.
