Abstract |
We retrospectively analyzed 155 AML patients with DAT mutations at diagnosis who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) at complete remission. Of the 155 AML patients with DAT mutations at diagnosis, 59 (38.1%) patients had persisting DAT mutations pretransplantation. Compared to patients with pretransplant DAT transitions, patients with persisting DAT mutation burden were shown to be older (p = 0.004), and fewer patients had TET2 mutations at diagnosis (p = 0.033). Patients with persistent DAT mutation burden had shorter overall survival (OS) (3-year OS: 59.3% vs. 83.0%, p < 0.001) and disease-free survival (DFS) (3-year DFS: 56.1% vs. 83.0%, p < 0.001) with a higher cumulative incidence of relapse (CIR) (24.6% vs. 17.4%, p = 0.002) than those with DAT transitions. Additionally, multivariate analysis confirmed that persisting DAT mutations were an independent adverse factor for relapse, OS, and DFS. Collectively, persisting DAT mutations prior to allo-HSCT at complete remission for AML correlated with negative outcomes.
