The aim of the study is to determine the prognostic relevance of CD200/CD56 expression in adult acute lymphoblastic leukemia patients. The expression of CD200 and CD56 by blast cells was assessed by flow cytometry before start of chemotherapy in 70 B-ALL patients. Positive expression of CD200 was detected in 46 patients (66%) and CD56 was detected in 7 patients (10%) out of 70 patients, respectively. Only 3 patient (4.3%) had co-expression for CD200+ and CD56+. Splenomegaly and thrombocytopenia were frequently observed more in CD200+ patients. Increased frequency of CD34+ was associated with CD200+ and CD56+ patients. The CD200+ and CD56+ subgroups of B-ALL patients had inferior OS and DFS compared to CD200ΓΆΒ?Β? and CD56ΓΆΒ?Β? patients. In conclusion, CD200+ and or CD56+ positive expression in B-ALL patients at diagnosis is a poor prognostic biomarker. Identification of CD200+ and CD56+ expression at diagnosis is recommended for better stratification of adult B-ALL patients.
