Evaluation of Minimal Residual Disease in B-Lineage Acute Lymphoblastic Leukemia Using EuroFlow Approaches
Background & Aims. Evaluation of the minimal residual disease (MRD) at different stages of chemotherapy is one of key prognostic factors and a factor of stratification of patients into risk groups in acute lymphoblastic leukemia (ALL). The MRD detection on Day 15 and at later stages is based on...

| description | Background & Aims. Evaluation of the minimal residual disease (MRD) at different stages of chemotherapy is one of key prognostic factors and a factor of stratification of patients into risk groups in acute lymphoblastic leukemia (ALL). The MRD detection on Day 15 and at later stages is based on identifying blast cells with a leukemia-associated immune phenotype. The aim is to assess the potential of 8-color standardized EuroFlow panels and to detect individual criteria for MRD monitoring during primary diagnosis.
Materials & Methods. The analysis included data on the primary immune phenotype and MRD assessment during chemotherapy in 10 adults and 35 children with a confirmed diagnosis of B-cell precursors ALL.
Results. The ALL phenotype characteristics at the stage of primary diagnosis permit to make the most complete description of the of 8-color standardized EuroFlow panels. This gives an opportunity to select the most informative antigen combinations for further MRD monitoring. Combinations with CD58/CD38, CD81/СD9 antigen expression, as well as assessment of pan-myeloid CD13, CD33 antigen co-expression may be recommended as the most frequent aberrant immune phenotypes of blast cells in ALL. As for B-lineage progenitor cells in children on Day 15 of the induction therapy, a detection of TdT+ сyCD22+ cell population is necessary in addition to the quantification of CD10+ and/or CD34+ В-lineage progenitor cells.
Conclusion. Therefore, the 8-color standardized EuroFlow panels permit not only to characterize the primary ALL immune phenotype in details, but may also be widely used for MRD evaluation at all stages of chemotherapy. |
