Prognostic value of cross-lineage expression of the myeloid-associated antigens CD13 and CD33 in adult B-lymphoblastic leukemia: A large real-world study of 1005 patients.

In real-world practice, CD13/CD33 expression can predict the risk of MRD in patients without TKI experience, but has no adverse effect on the prognosis of adult B-ALL patients. Incorporating CD13/CD33 into the standard antibody panels of B-ALL diagnosis and MRD measurements can help predict relapse risk and decisions on therapy options.
