A next-generation sequencing-based assay for minimal residual disease assessment in AML patients with FLT3-ITD mutations.

ABSTRACT: Internal tandem duplications in fms-like tyrosine kinase 3 (FLT3-ITDs) are common in acute myeloid leukemia (AML) and confer a poor prognosis. A sensitive and specific assay for the detection of minimal residual disease (MRD) in FLT3-ITD mutated AML could guide therapy decisions. Existing assays for MRD in FLT3-ITD AML have not been particularly useful because of limited sensitivity. We developed a sensitive and specific MRD assay for FLT3-ITD mutations using next-generation sequencing. The initial validation of this assay was performed by spiking fixed amounts of mutant DNA into wild-type DNA to establish a sensitivity of detection equivalent to ≥1 FLT3-ITD-containing cell in 10 000, with a minimum input of 100 000 cell equivalents of DNA.
