Background: Elderly patients with acute myeloid leukemia (AML) have a poorer prognosis than younger ones. Several factors contribute to the poor outcomes for this patient group.
Patients And Methods: This study investigated the epidemiology, clinical characteristics, treatment, and clinical outcomes of elderly Thai patients with AML. This 3-year, prospective, multicenter study was focused on Thai patients with AML aged over 60 years who were diagnosed between 2014 and 2016.
Results: Of 680 patients with AML, 235 elderly patients with AML (34.6%) were identified, with a mean age of 70 ± 8 years. Using a 3-group cytogenetic risk classification (favorable, intermediate, and adverse risk), the proportions of patients in each category were 3.6%, 73.8%, and 22.6%, respectively. The median follow-up time for surviving patients was 846 days. The median overall survival (OS) of the patients was 128.2 days (range, 0-1205 days), with a 1-year OS of 13%. From a multivariate analysis, the significant factors associated with an improved long-term OS were patients with an Eastern Cooperative Oncology Group performance status 0 to 2 and those receiving intensive therapy.
Conclusion: Our study confirms the high prevalence of AML in elderly patients with generally poor outcomes. Selected patients with a good performance status and those who received intensive induction treatment could have a long-term survival.

Accurate prediction of survival in patients with acute myelogenous leukemia (AML) is challenging. Therefore, we developed a predictive survival model using endocrine-related gene expression to identify an endocrine signature for accurate stratification of AML prognosis. RNA matrices and clinical data for AML were downloaded from a training dataset (GEO) and two validation datasets (TCGA and TARGET).

Robust genetic characterization of paediatric AML has demonstrated that fusion oncogenes are highly prevalent drivers of AML leukemogenesis in young children. Identification of fusion oncogenes associated with adverse outcomes has facilitated risk stratification of patients, although successful development of precision medicine approaches for most fusion-driven AML subtypes have been historically challenging. This knowledge gap has been in part due to difficulties in targeting structural alterations involving transcription factors and in identification of a therapeutic window for selective inhibition of the oncofusion without deleterious effects upon essential wild-type proteins.

Recent treatment advances have drastically improved outcomes for these diseases, but the overall survival (OS) is still exceptionally low due to the infiltration of leukemic cells in the central nervous system (CNS).

Background: The management of pediatric acute myeloid leukemia (AML) is based on the prognostic risk classification of initial leukemia. Targeted next-generation sequencing (NGS) is a reliable method used to identify recurrently mutated genes of pediatric AML and associated prognosis.
Methods: In this study, we retrospectively evaluated the prognostic, and therapeutic utility of a targeted NGS panel covering twenty-five genes, in 21 children with de novo and 8 with relapsed or secondary AML.
