Molecular measurable residual disease before transplantation independently predicts survival and relapse risk in adult lysine methyltransferase 2a‐rearranged acute myeloid leukemia

Patients with lysine methyltransferase 2a (KMT2A)-rearranged (KMT2A-r) acute myeloid leukemia (AML) are assigned to intermediate-risk and adverse-risk categories at diagnosis. However, the value of molecular measurable residual disease (MRD) status in patients who have KMT2A-r AML before allogeneic hematopoietic stem cell transplantation (allo-HSCT) in adult cohorts has rarely been evaluated.
