However, patients with FLT3-ITD low allele burden and short length did not show significantly different OS (P=0.329) and EFS (P=0.288) rates compared with FLT3-ITD wild-type CN-AML when the analysis was restricted in HSCT-performed CN-AML patients (n=112; Figure 2). Here, FLT3 is linked to acute myeloid leukemia.
