IDH1 and acute myeloid leukemia: When restricting the analysis to IDH1/2-mutated patients, the univariate analyses for OS and EFS confirmed also in this AML subset that age (HR 1.03, 95% CI 1.00–1.06, p = 0.019), WBC (HR 1.0, 95% CI 1.00–1.00, p = 0.007), and HMA (HR 2.03, 95% CI 1.07–3.83, p = 0.030) were associated with inferior survival.
