FLT3 and acute myeloid leukemia: Furthermore, although this only refers to a limited number of patients, the OS of UBTF-TD AML tended to worsen with the cooccurrence of WT1 mutations (3y-OS: 20% [95%CI: 6–69%] vs. 91% [95%CI: 75–100%], p-value = 0.002) or FLT3-ITD (3y-OS: 25% [95%CI: 8–83%] vs. 77% [95%CI: 57–100%], p-value = 0.008)(Supplementary Fig. 5).
