Abstract

According to the recent National Comprehensive Cancer Network (NCCN) guidelines, the risk level in acute myeloid leukemia (AML) patients with and double mutation (AML ) depends on the allelic ratio of . But despite a low or high allelic ratio of , AML patients belong to the favorable or intermediate risk, for whom allogeneic stem cell transplantation is not obligated. However, some latest studies pointing out that and double mutation patients showed an inferior prognosis, which have raised concern about the risk categorization and more effective treatment of AML patients. A total of 76 patients were selected for coexisting and mutations with normal cytogenetics. The prognostic risk factors were analyzed, and treatment strategies including allogeneic stem cell transplantati1on and chemotherapy were compared. In 76 AML patients, 36.8% of patients had hyperleukocytosis (HL) and mutation was the most common concomitant gene (23.7%). For 53 patients in the complete remission (CR), 22 had received allogeneic hematopoietic stem cell transplantation (allo-HSCT) on first complete remission (CR1). Patients in transplantation group had better overall survival (OS) and disease-free survival (DFS) than chemotherapy only (=0.002 and 0.001, respectively). In multivariable Cox model analyses, HL and mutation were independent adverse prognostic factors (all <0.05) for AML patients. Nevertheless, allo-HSCT was an independent good factor of OS and DFS (=0.001 and 0.000; HR =0.173 and 0.138; 95% CI were 0.062-0.483 and 0.049-0.389). And allo-HSCT could moderately improve the poor prognosis of AML Although, AML patients are categorized as favorable or intermediate risk levels according to recent NCCN and ELN guidelines, these patients should receive allo-HSCT in CR1 for a longer survival. AML patients with mutation had a very poor prognosis, and allo-HSCT could moderately improve their survival.
