Table 1 Frequency of CD66c and myeloid antigen expression. Cases with >20% blasts are regarded positive, coexpression of CD66c and other MyAg is tested by Fisher's exact test.

From: Myeloid antigens in childhood lymphoblastic leukemia:clinical data point to regulation of CD66c distinct from other myeloid antigens

Molecule No of cases (total = 365) Proportion [%] Coexpression with CD66c
CD66c 156 43   
CD33 85 23   
CD15 72 20   
CD13 57 16   
CD65 14 3.8   
CD66c and CD33 21 5.8 mutually exclusive p = 0.002
CD66c and CD15 30 8.2 random NS
CD66c and CD13 9 2.5 mutually exclusive P < 0.0001
CD66c and CD65 2 0.55 mutually exclusive p = 0.029
