Study of relapse or refractory (R/R) FLT3-mutated acute myeloid leukemia (AML) using electronic medical records (EMR): First analysis from a multicenter, retrospective cohort study

In AML, the ability to target disease-related mutations is an important therapeutic innovation. FMS-like tyrosine kinase 3 (FLT3) mutations (FLT3^mut+) are common in AML and confer a negative impact on prognosis. Since FLT3 mutational status can change over the course of the disease and FLT3-targeting therapies may benefit FLT3^mut+ patients (pts), FLT3 mutational testing is recommended for R/R AML pts, even if testing was performed at initial diagnosis. As the landscape of FLT3^mut+ R/R AML evolves, it is important to understand how the utilization/sequencing of therapies and application of FLT3 mutational testing impacts pts in real-world settings. The objective of this analysis was to examine real-world data from a large, multicenter, collaborative EMR database to learn more about treatment and FLT3 testing patterns in pts with FLT3^mut+ R/R AML.
