RUNX1T1 (RUNX1 Partner Transcriptional Co-Repressor 1)

All patients remained disease-free, with no events of measurable residual disease (MRD) positivity by flow cytometry or molecular analysis documented. These findings preliminarily confirm that venetoclax, cytarabine, and homoharringtonine-based cytoreductive therapy is a safe and effective bridging therapy for allo-HSCT in patients with refractory/relapsed AML and RUNX1::RUNX1T1 fusion gene.

Our preliminary data provides proof of principle to suggest that environmental factors associated with childhood leukaemia risk have the potential to induce chromosomal translocations. Whilst this study is not designed to estimate in vivo risk or translocation frequency, it has allowed us to demonstrate a biologically plausible mechanism for epidemiological associations. Understanding the risk factors contributing to leukaemia-initiating events will be essential to refine public health policy and tailor prevention strategies.

This study established internally validated 3-year OS and RFS nomograms for pediatric RUNX1::RUNX1T1-positive AML with excellent discrimination and clinical utility. Prospective multicenter validation is warranted to confirm the robustness and facilitate clinical adoption.

In RUNX1::RUNX1T1 patients, older age, elevated initial white blood cell count, lower hemoglobin, lower initial fusion transcript load, and the presence of FLT3-ITD or KIT D816/D822 mutations were associated with an increased likelihood of PC2 nonresponse. Based on these variables, we developed a weighted scoring system with good discrimination to identify RUNX1::RUNX1T1 patients at high risk of PC2 nonresponse.

This study evaluated the clinical efficacy of venetoclax and azacitidine (VEN+AZA) versus CAG (cytarabine, aclarubicin, and granulocyte colony-stimulating factor) for newly diagnosed adult acute myeloid leukemia (AML) unfit patients. 31.7 % (P = 0.20). Patients with age ≥ 60 y (EFS, P = 0.032), ECOG≥ 2 (EFS, P = 0.047), secondary AML (OS, P = 0.015; EFS, P = 0.039), ELN intermediate-adverse karyotype (OS, P = 0.034; EFS, P = 0.044), RUNX1 mutation (OS, P = 0.003; EFS, P = 0.003) and IDH1/2 mutation (EFS, P = 0.039) showed a preference for VEN+AZA regarding OS, and patients with SRSF2 mutation favored CAG in OS (P = 0.031).

After being diagnosed with AML with t(8;10;21)(q22;q22;q22.1), he received standard induction therapy consisting of cytarabine for seven days and idarubicin for three days, but failed to achieve remission. Reinduction and salvage therapies were also ineffective. This variant form may be associated with a lower likelihood of achieving complete remission (CR) after initial induction therapy. Failure to achieve CR after initial induction therapy in AML is an adverse prognostic factor; therefore, the presence of t(8;21)/RUNX1::RUNX1T1 with three-way translocations may warrant consideration of hematopoietic stem cell transplantation at an earlier stage in the treatment course.

Through the examination of intercellular communications among various putative fTF+ and normal cell populations, we developed a ligand-receptor (L-R)-based risk-scoring model with independent prognostic value. Collectively, these findings provide insights into the cells of origin of LSCs and the implications of fTF expression for the immune landscape of AML.

LSPC-Cycle, FLT3-ITD and NUP98::KDM5A were considered independent prognostic factors in multivariate analysis. Findings indicate the prognostic relevance of cellular hierarchy and the importance of integrating hierarchy-specific molecular profiles for improved risk stratification and treatment formulation.

This study revealed that patients aged ≥50 years displayed more complex genetic aberration profiles and experienced significantly poorer prognoses compared to their younger counterparts. These findings provided novel insights for optimizing treatment strategies for middle-aged and elderly AML patients in the Chinese population.
