Impact of FLT3/TKD mutation status on OS stratified according to cytogenetic abnormalities. (A) Kaplan-Meier curves stratified according to FLT3/TKD status and cytogenetic risk group. Because only 3 patients with adverse cytogenetics carried a FLT3/TKD mutation, this curve is not shown. (B) Analysis of OS showing the effect of FLT3/TKD status stratified according to cytogenetic abnormality and category.
