[The limited possibility of using a simplified approach to detect minimal residual disease by the flow cytometry technique in children with precursor B-lineage acute lymphoblastic leukemia].

Minimal residue disease (MRD) is a state in which the tumor cells remain in the patient in the amounts unrecognizable with the standard cytological techniques. Flow cytometry is one of the basic methods for evaluation of MRD in precursor B-lineage acute lymphoblastic leukemia (PBLALL). The so-called simplified three-color analysis using the combination of CD19/CD10/CD34 antibodies has been proposed to detect MRD in the midcourse of induction therapy.

[Minimal residual disease monitoring by flow cytometry in children with acute lymphoblastic leukemia].

The cells that have avoided the action of antitumor drugs may be retained after remission achievement during induction therapy and consolidation. A combination of these cells is given the name minimal residual disease (MRD). Multicolor flow cytometry has recently attracted considerable interest as the most promising method for measuring the content of residual tumor blasts.
