Abstract
BACKGROUND The potential loss of CD19 during targeted treatment of B cell precursor acute lymphoblastic leukemia (BCP-ALL) can hamper flow cytometric minimal residual disease (MRD) monitoring. In the current study, we present expression data for antigens that are candidates for CD19 substitution: surface CD22, CD24, CD10, and intracellular (i) CD79a. METHODS Bone marrow samples from 519 consecutive children (below 18 y.o.) with primary BCP-ALL were studied with a focus on expression of CD19, CD10, CD22, CD24, and iCD79a. As these antigens are planned to be used as substitutions for CD19 for primary B cell gating, only total expression on the leukemic population (≥95% cells) was considered appropriate. RESULTS It was found that each of these antigens is totally expressed in nearly 90% of patients. For each single marker, a subgroup of patients without complete positivity presented with BCP-ALL harboring diverse cytogenetic and molecular genetic aberrations. Based on expression data, we have developed algorithm of simultaneous application of these antigens for initial B-lineage compartment gating, that is applicable for nearly all patients after CD19 targeting. CONCLUSION We conclude that the addition of CD22, CD24, and iCD79a to the conventional antibody panel and their application together with CD10 allow for the identification of B-lineage compartment including residual tumor blasts, for MFC-MRD searching in virtually all patients with BCP-ALL after CD19-directed treatment.

Abstract
CD19-directed treatment in B-cell precursor acute lymphoblastic leukaemia (BCP-ALL) frequently leads to the downmodulation of targeted antigens. As multicolour flow cytometry (MFC) application for minimal/measurable residual disease (MRD) assessment in BCP-ALL is based on B-cell compartment study, CD19 loss could hamper MFC-MRD monitoring after blinatumomab or chimeric antigen receptor T-cell (CAR-T) therapy. The use of other antigens (CD22, CD10, CD79a, etc.) as B-lineage gating markers allows the identification of CD19-negative leukaemia, but it could also lead to misidentification of normal very-early CD19-negative BCPs as tumour blasts. In the current study, we summarized the results of the investigation of CD19-negative normal BCPs in 106 children with BCP-ALL who underwent CD19 targeting (blinatumomab, n = 64; CAR-T, n = 25; or both, n = 17). It was found that normal CD19-negative BCPs could be found in bone marrow after CD19-directed treatment more frequently than in healthy donors and children with BCP-ALL during chemotherapy or after stem cell transplantation. Analysis of the antigen expression profile revealed that normal CD19-negative BCPs could be mixed up with residual leukaemic blasts, even in bioinformatic analyses of MFC data. The results of our study should help to investigate MFC-MRD more accurately in patients who have undergone CD19-targeted therapy, even in cases with normal CD19-negative BCP expansion.
