One of the most common acute myeloid leukemia (AML) mutations is the FMS-like tyrosine kinase 3 (FLT3) mutation, which is made up of 2 major types. The more common FLT3-internal tandem duplication (ITD) mutation is associated with poor prognosis, high relapse rate, and poor overall survival (OS), while the prognosis of FLT3-tyrosine kinase domain (TKD) mutation remains unclear.1
