TET2 mutation

We developed a weighted genomic model and diagnostic workflow showing that combining genomic signatures with bone marrow monocyte frequencies in OM-CMML more accurately predicts progression to overt CMML. These findings support integrating genomic determinants, and our clinic-ready diagnostic workflow, into the CMML diagnostic framework to improve accuracy.

According to previous reports, lymphomatous effusion, which is frequently measured in months, is associated with a short survival. Based on these data and current World Health Organization (WHO) and National Comprehensive Cancer Network (NCCN) guidance, we propose a practical fluid-based diagnostic algorithm that integrates cytology, ancillary tools, and lymph node biopsy when feasible, and we highlight the need for standardized effusion-based workflows, multicenter registries, and the integration of liquid biopsies, multiomics, and artificial intelligence-assisted cytology to refine risk stratification and guide therapy in this distinct subgroup.

These results suggest an association of PRDM16 overexpression with the NPM1/FLT3-ITD/DNMT3A triple-mutant AML genotype, typically linked to high leukemia stem cell frequencies and poor prognosis. Importantly, within this adverse AML subtype low PRDM16 expression is an independent prognostic marker for favorable outcome, supporting an anti-leukemic mechanism in AMLs with repressed PRDM16 transcription.

Given the patient's age and tumor location, we administered a reduced dose of DeVIC, followed by radiotherapy, achieving partial remission. This case expands the spectrum of EBV-associated T-cell lymphomas and highlights the need for additional cases to refine the classification and management.

Current research has revealed that ASXL1 mutations in MDS predict demethylating agents (HMAs) resistance, the combination of HMAs and Venetoclax (VEN) achieved an ORR of 87%. DNMT3A R882 mutations induce decitabine sensitivity via hemi-methylated enhancer trapping, and TET2 mutations enhance HMAs efficacy only in ASXL1 wild-type contexts (ORR 62.1% vs. co-mutated 19%). RUNX1 aberrations reduce chemotherapy responses (18.9% ORR in high-risk MDS) through DNA repair impairment, while BCOR/EZH2 loss drives cytarabine resistance. TP53 multi-hit lesions correlate with poor survival (OS <12 months) but respond to eprenetapopt-azacitidine (ORR 73%), and IDH1/2 inhibitors achieve durable remissions (ivosidenib ORR 83.3%, mOS 35.7 months). In this paper, we systematically illustrate the correlation between key gene mutations and the response to HMAs, chemotherapy and targeted therapies in MDS patients. This article summarizes the current evidence on gene mutations as predictive biomarkers and discusses the direction of individualized therapy.

A nomogram model based on these findings demonstrated robust predictive performance (AUC = 0.735) and was validated by the Beat AML database. The prognostic impact of TET2 mutations is not determined by VAF, but rather by TET2 clonal dominance and the interplay between mutations within the same clone.

LETM may represent an additional warning feature in such presentations. Vigilance for clinical and radiologic red flags, the adjunctive use of CSF ctDNA analysis, and early reconsideration of diagnosis with timely biopsy should be emphasized to improve outcomes in patients with CLIPPERS-like syndromes.

These findings demonstrate that Tet2 is essential for balancing proliferation and terminal differentiation of IgG1+ GC B-cells during the humoral response. The impaired regulation of this balance due to Tet2 loss provides mechanistic insight into a contributory pathway that may facilitate DLBCL transformation in TET2-mutated cases.

To our knowledge, this is the first reported case demonstrating the use of tagraxofusp in a patient with BPDCN and advanced chronic kidney disease, showing that even a minimum of tolerated treatment dose can induce a sustained response. Despite the risk of adverse events, tagraxofusp should be considered a viable treatment option for elderly patients with poor performance status and significant comorbidities who are ineligible for intensive chemotherapy or stem cell transplantation, as even limited exposure may achieve meaningful clinical responses.

Emerging therapeutic strategies, including inflammasome inhibition, STING modulation, and epigenetic restoration, highlight its potential as a modifiable risk factor. This narrative review synthesizes current epidemiological, mechanistic, and translational insights, framing CHIP as an emerging causal factor in cardiometabolic disease and as a promising target for precision medicine in aging populations.
