Studies have shown that FLT3-ITDneg/NPM1mut confers good overall survival (OS) and leukaemia-free survival (LFS) compared to FLT3-ITDpos/NPM1wt, which are known to be poor prognostic indicators, with shorter remission duration and higher relapse rates compared to FLT3-ITDneg/NPM1wt and FLT3-ITDneg/NPM1mut patients [19]. Here, FLT3 is linked to leukemia.
