In AML, the ability to target disease-related mutations is an important therapeutic innovation. FMS-like tyrosine kinase 3 (FLT3) mutations (FLT3mut+) 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 FLT3mut+ patients (pts), FLT3 mutational testing is recommended for R/R AML pts, even if testing was performed at initial diagnosis. As the landscape of FLT3mut+ 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 FLT3mut+ R/R AML.
