Despite remarkable advances in molecular and cell biology of acute myeloid leukemia(AML),AML patients still frequently relapse and have low 5-year overall survival(OS)rates.1 It is worth noting that a recent study from the registry or clinical trial compilation has reported an improvement in the OS of adult AML patients,especially those under 60 years of age.
