The molecular mechanisms underlying CNS tumors have been extensively studied, revealing critical insights into targeted therapy selection and tumor biology. A guideline by Capper emphasizes the importance of rational molecular testing for gliomas and other CNS tumors, noting that while some tumor-agnostic treatments exist, their efficacy in adult patients remains limited, necessitating prospective clinical trials for better outcomes (ref: Capper doi.org/10.1093/neuonc/). Marquardt's research on MYC-driven medulloblastoma highlights the potential of Tacedinaline, a class I HDAC inhibitor, to target tumor growth and enhance susceptibility to macrophage phagocytosis, indicating a promising multimodal therapeutic approach (ref: Marquardt doi.org/10.1136/jitc-2022-005871/). Additionally, Frontzek's molecular profiling of EBV-associated diffuse large B-cell lymphoma reveals the complexity of EBV's role in lymphomagenesis, identifying recurrent somatic copy number alterations that could inform treatment strategies (ref: Frontzek doi.org/10.1038/s41375-022-01804-w/). Biczok's study on extracranial meningioma metastases underscores the need for larger cohorts to validate findings related to BAP-1 alterations, which may influence clinical management (ref: Biczok doi.org/10.1186/s40478-023-01505-0/). Lastly, Tauziède-Espariat's work on pediatric posterior fossa ependymomas emphasizes the diagnostic significance of NF2 and ZFTA evaluations, contributing to a better understanding of tumor classification and treatment (ref: Tauziède-Espariat doi.org/10.1186/s40478-023-01503-2/).
