Recent studies have significantly advanced our understanding of tumor biology and the molecular mechanisms underlying various cancers. A notable discovery is the role of trogocytosis in CAR-T cell dysfunction, where tumor cells acquire CAR molecules from CAR-T cells, leading to antigen loss and masking, ultimately impairing the efficacy of CAR-T therapies (ref: Zhai doi.org/10.1038/s41392-023-01708-w/). In glioblastoma research, a new subtype termed 'de novo replication repair deficient glioblastoma, IDH-wildtype' has been identified, showing a median overall survival of 36.8 months, significantly longer than the conventional subtype (15.5 months) (ref: Hadad doi.org/10.1007/s00401-023-02654-1/). Furthermore, the classification of diffuse midline gliomas has been refined, revealing a new subtype characterized by H3 K27 and BRAF/FGFR1 alterations, which underscores the heterogeneity within this aggressive tumor type (ref: Auffret doi.org/10.1007/s00401-023-02651-4/). Concurrent gliomas in patients with multiple sclerosis have also been studied, indicating that MS does not predispose individuals to glioma development, providing insights into the neuroimmunological interactions in these patients (ref: Sahm doi.org/10.1038/s43856-023-00381-y/). Additionally, the molecular characteristics of pilocytic astrocytomas in adults have been contrasted with pediatric cases, revealing significant differences in genetic drivers (ref: Bode doi.org/10.1111/nan.12949/). Lastly, the distinction between teratoma-associated Wilms tumors and pure Wilms tumors has been clarified, highlighting their unique molecular features (ref: Kommoss doi.org/10.1111/his.15116/).
