EZH2 mutation

Given the patient's advanced age and underlying MF, two cycles of a low-intensity chemotherapy regimen primarily based on the "VP regimen (Vincristine + Prednisone) combined with Azacitidine" were administered...Patient tolerability to intensive chemotherapy and novel targeted agents (e.g., Venetoclax) is poor, leading to a dismal prognosis...This case not only serves as a unique model illustrating the complex evolution of a malignant clone but also profoundly reveals the unique therapeutic challenges and extremely poor survival outcome resulting from the convergence of advanced age, MF background, and MPAL transformation. It offers pivotal real-world evidence for the clinical management of this specific patient population and highlights the need to explore novel therapeutic strategies.

This first-reported association between such crystals and EZH2/DNMT3A-mutated AML highlights their potential as high-risk markers. The findings implicate epigenetic dysregulation in treatment resistance and thrombogenesis, warranting cryo-EM studies to elucidate crystal composition and mechanisms. Clinically, this supports vigilant thromboprophylaxis and exploration of combined epigenetic/anticoagulant therapies for similar high-risk cases.

In contrast, majority of BCL6 translocations in thyroid EMZL juxtaposed the BCL6 gene to the IGHJ/D region without encompassing the Eμ enhancer or its partner genes in an opposite orientation, thus less likely to lead to constitutive BCL6 transactivation. The above genetic changes likely dysregulate B-cell maturation and peripheral tolerance, thus offer significant molecular insights into the pathogenesis of thyroid lymphomas, particularly underpinning autoimmunity in the lymphomagenesis and potentially explaining the overlap in histopathology between EMZL and FL.

The presence of a single MRG mutation did not confer a worse prognosis in favorable-risk AML, whereas a high MRG mutation burden (≥2 mutations) was independently associated with poorer LFS. This study suggests that quantifying the MRG mutation burden may inform risk stratification in this patient population.

MRD based solely on secondary type mutations lacked predictive value, whereas MRD of non-DTA mutations in CR was associated with increased CIR in st-AML (subdistribution hazard ratio &lsqb;SHR] 3.25; P< .001). Molecularly defined st-AML, including st-MDS/AML, defines a distinct AML category with a unique genetic, clinical and treatment response profile, in which next-generation sequencing (NGS)-based MRD holds markedly prognostic significance.

The allelic ratio of FLT3-ITD did not further stratify OS and RFS in this subgroup. These findings suggest that the prognostic relevance of MRG mutations in FLT3-ITD AML is modulated by NPM1 co-mutational status and mirror findings in AML lacking FLT3-ITD.
