A FABulous Couple: Adding PHENotype to GENotype Improves HMA/VEN Response Prediction in AML

In a large retrospective multicenter study of patients with acute myeloid leukemia treated with hypomethylating agents and venetoclax, Lachowiez and colleagues examine the interplay among genetic mutations, disease phenotype, and clinical outcomes. They show that within genetic subgroups-particularly NPM1 wild-type cases-monocytic differentiation is linked to poor treatment response and inferior long-term prognosis, adding a phenotypic layer to genetics-based response prediction.
