    NKCC1: A key regulator of glioblastoma progression. (PubMed, Mol Oncol)
    These findings identify NKCC1 as a regulator of GBM progression and recurrence, linking chloride transporter imbalance to GABAergic signaling. Targeting NKCC1 and restoring chloride homeostasis may provide promising new treatment strategies.

    Identification of new prognostic molecular markers in glioblastoma: a single-center retrospective study. (PubMed, Oncologist)
    We identified new prognostic markers in GBM, showing for the first time that EGFR substitutions improve OS. Validation in external cohorts and preclinical studies is needed.

    MGMT Promoter and Enhancer Methylation in Melanoma Brain Metastases and Glioblastoma: Shared and Distinct Features. (PubMed, Cells)
    We focused on MGMT because MGMT promoter methylation is used as a predictive marker for temozolomide response in GB, but its role in MBM has been discussed controversially...GB exhibited higher methylation, particularly in promoter and intergenic enhancers, and stronger associations between methylation and overall survival than MBM. These results highlight both conserved and tumor-specific MGMT regulation, reflecting the complexity of epigenetic control in brain malignancies and emphasizing divergent evolution between MBM and GB.

    Glioblastoma survival in rural America: a 10-year experience from a quaternary care center. (PubMed, J Neurooncol)
    In a predominantly rural state served by a primary academic neuro-oncology program, median overall survival for GBM was 12.7 months indicating centralized care eliminates rural-urban survival gaps in GBM.

    Pediatric high-grade gliomas, H3-wildtype, IDH-wildtype: Refining diagnostic criteria and exploring clinical associations. (PubMed, Neurooncol Pract)
    The findings challenge current WHO diagnostic criteria regarding H3K27me3 retention and demonstrate the critical role of molecular diagnostics, particularly methylation profiling, in refining classification and guiding clinical management. These results advocate for re-evaluation of existing diagnostic frameworks to better accommodate the observed variability and associations in this challenging tumor subtype.

    Pediatric H3 G34-mutant diffuse hemispheric glioma: clinical, imaging and molecular prognostic factors, MGMT expression, and temozolomide response. (PubMed, Acta Neuropathol)
    Our findings reaffirm the dismal outcomes of pediatric H3 G34-mutant DHG, which exhibits radiation resistance, frequent widespread disease, and a novel mechanism of MGMT regulation. Our data support the use of frontline TMZ in pediatric patients and underscore the importance of GTR when feasible.

    Rethinking treatment de-escalation in elderly glioblastoma: Lessons from a multicenter real-world cohort. (PubMed, Neurooncol Adv)
    Post-operative treatments included (1) chemoradiotherapy (CRT; 60Gy in 30 fractions or 40Gy in a15 fractions), (2) temozolomide (TMZ) monotherapy, (3) radiotherapy alone (RT), or (4) best supportive care...Treatment decisions should be guided by functional and clinical fitness rather than chronological age. These real-world data highlight the importance of integrating clinical and functional factors into management of elderly GBM.
