[Precision genomic and translational medicine for acute myeloid leukemia].

Leukemia is a group of hematologic malignancy that has unfavorable prognosis and unclear mechanisms. In recent years, advances in leukemia research encompass the discovery of novel targets in acute myeloid leukemia drug resistance, epigenetic crosstalk in mixed lineage leukemia (MLL) leukemogenesis, genetic mechanisms of aggressive NK-cell leukemia, as well as the critical role of key epigenetic regulator in acute myeloid malignancy. Remarkably, researchers revealed that the histone modifying gene SETD2 as a new tumor suppressor and therapeutic target in patients with acute myeloid leukemia. Furthermore, low-dose chemotherapy as a frontline regiment in treating pediatric acute myeloid leukemia can substantially reduce the toxic side effects and treatment costs without impairing efficacy. Although advances in cancer genomics have greatly increased our understanding of the molecular characteristics in tumor biology, recent studies suggest that Darwinian evolution of intratumor heterogeneity represents a major challenge to develop therapeutic strategies to improve disease control. Researchers also dissected the distinct evolutionary dynamics under different chemotherapy regimens and the corresponding applications in the evaluation of treatment outcomes. Altogether, these efforts offered new opportunities for the development of acute myeloid leukemia diagnostics and therapeutics.
