Association between molecular profile and outcomes in secondary or adverse cytogenetic AML: A FILO study

Learning objective: After reading this article, learners will be able to cite a new clinical development in acute myeloid leukemia.


Results from a FILO study, investigating the association between molecular profile and outcome following intensive chemotherapy in older fit patients >60 years with secondary or adverse cytogenetic acute myeloid leukemia (AML) enrolled in the multicenter, prospective Rev5Aza trial (NCT01301820), were published in the American Journal of Hematology. Molecular profiles were available for 97 and 73 patients from the Rev5Aza and the control cohort, respectively.

Key data: Adverse cytogenetics were associated with worse overall survival (OS) than therapy-related acute myeloid leukemia [median OS, 8.28 vs 19.68 months; p < 0.001] in the Rev5Aza cohort. Among patients with adverse cytogenetics, those with complex karyotype (CK) vs other cytogenetic abnormalities (p < 0.001) as well as those with TP53 mutations vs de novo or secondary AML (p < 0.001) had lower OS. The control cohort showed similar outcomes, except that patients with CK, TP53 mutations, or both had comparable OS.

Key learning: The findings suggest that cytogenetic and molecular risk stratification is more predictive of outcomes compared with clinical history in older patients with either secondary or adverse cytogenetic AML.
