Aberrant expression of one or more myeloid antigens including CDI3, CDI5, CD33 and CD34 was found in 30.2% of cases. The relationship of myeloid positive (MY+ ALL) and negative cases (MY- ALL) with patient characteristics were studied. No significant differences in clinical features, response to therapy or survival was found between the two groups. Study of each marker separately indicated an association between expression of CD5 and CD 1 0 with age and expression of CD20 and CD33 with decrease in hemoglobin (p SP - 111 EP - 114 AU - AMIRGHOFRAN, Z AU - SHAMSEDDIN, A AU - SHAHRIARI, M AD - From the Department of Immunology Shiraz University of Medical Sciences, Shiraz, KW - Myeloid antigens KW - Acute lymphoblastic leukemia KW - Myeloid positive ALL.
