Antibodies included in the panel were specific against Tdt, HLA-DR, CD19/CD2O/CD22, CALLA (CD1O), CD2, CD11C as well as against Ig heavy chains. Of 86 cases analyzed, 48 cases were of ALL, (25 of common pre-B ALL, 15 of pre-B/NULL and 8 of T ALL phenotype), twenty-four (24) out of 86 cases were of nonlymphoblastic (AML/AMML) type.
