The neurotrophic receptor tyrosine kinase (NTRK) gene fusions occur in a large number of solid tumors and tropomyosin receptor kinase (TRK) inhibitors exhibit attractive antitumor activity. However, the occurrence of NTRK fusions is rare in hematological malignancies, and just a few cases or pre-clinical researches have been reported. This case report presents a refractory acute myeloid leukemia (AML) patient, accompanied with ETV6::NTRK3, was failed by traditional chemotherapy, then entered long-term remission after hematopoietic stem cell transplantation (HSCT) and maintenance therapy with entrectinib. It was the first successful use of the TRK inhibitor in an AML patient after HSCT.

We retrospectively analyzed a large international cohort of 1113 patients with aplastic anemia to evaluate treatment choice and outcome in elderly patients as compared with a younger population. Overall, 319 (29%) patients were > 60 years old at diagnosis (60-64 years (n = 85), 106 65-69 years (n = 106), and 128 > 70 years (n = 128)). Elderly patients showed a more severe thrombocytopenia at onset and a significantly lower overall response (complete plus partial) to first-line therapy at 6 months as compared to younger patients (47% vs.

Introduction: DNA methylation inhibitors have been approved for the prevention of Acute Myeloid Leukemia (AML), and their safety profile is not fully characterized. This study was aimed at evaluating the adverse drug reactions (ADRs) of DNA methylation inhibitors by analyzing the individual case safety reports (ICSRs) collected in the EudraVigilance (EV) database.
Materials And Methods: The EV database managed by the European Medicines Agency was adopted.

Introduction: Acute myeloid leukemia (AML), a highly heterogeneous hematological malignancy, remains a major challenge in adult oncology. Stem cell research has highlighted the crucial role of long noncoding RNA (lncRNA) in regulating cellular differentiation and self-renewal processes, which are pivotal in AML pathogenesis and therapy resistance.
Methods: This study explores the relationship between cuproptosis-related lncRNAs and AML prognosis, providing novel insights into their impact on hematopoietic stem and progenitor cells.

Introduction: Iron overload (IOL) accumulates in myelodysplastic syndromes (MDS) from expanded erythropoiesis and transfusions. Somatic mutations (SM) are frequent in MDS and stratify patient risk. MDS treatments reversing or limiting transfusion dependence are limited.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a second-line treatment with curative potential for leukemia patients. However, the prognosis of allo-HSCT patients with disease relapse or graft-versus-host disease (GvHD) is poor. CD4 or CD8 conventional T (Tconv) cells are critically involved in mediating anti-leukemic immune responses to prevent relapse and detrimental GvHD.
