Real-world outcomes of intensive induction approaches in core binding factor acute myeloid leukemia.

Core-binding factor acute myeloid leukemia (CBF-AML) is characterized by the presence of inv(16)/t(16;16) or t(8;21) and is classified as a favorable risk by the 2022 European LeukemiaNet (ELN) guidelines. The CD33-targeting antibody-drug conjugate, gemtuzumab ozogamicin (GO), is commonly added to intensive chemotherapy (IC) in CBF-AML. We sought to compare outcomes in patients treated with IC with or without GO in CBF-AML. We included 200 patients with CBF-AML treated with IC across seven academic centers. Induction treatment regimens were categorized as IC alone, IC with GO, or IC with KIT inhibitor (dasatinib or midostaurin). Median follow-up for the whole cohort was 2.5 years. Three-year overall survival (OS) was 70% and 3-year event-free survival (EFS) was 51%. Patients treated with IC with GO experienced a 3-year EFS of 50% compared to those treated with IC alone who experienced a 3-year EFS of 47%, with no statistically significant difference (
