Additional flow cytometric markers that may be helpful for B-lymphoblastic leukemia/lymphoma MRD assessment include CD304, CD73, and CD86, which are expressed by leukemic blasts in a significant number of cases of B-lymphoblastic leukemia/lymphoma, and can be used to distinguish them from hematogones and normal B cells [13,14,15]. This evidence concerns the gene NT5E and lymphoma.
