Szczegółowy opis
Glioblastoma is characterized by disruption of the blood-brain barrier, which may influence tumor progression, neurological dysfunction, treatment delivery, and clinical outcomes. This study seeks to comprehensively characterize BBB integrity using multimodal approaches.
Participants with newly diagnosed GBM selected for surgical resection will undergo:
- Clinical and demographic data collection.
- Neurocognitive assessment using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) and Reading the Mind in the Eyes Test (RMET).
- High-resolution 3-Tesla MRI with and without gadolinium contrast, including structural and functional imaging sequences.
- Blood sampling for measurement of biomarkers associated with BBB disruption and neuronal injury, including S100β, GFAP, UCHL1, amyloid beta, phosphorylated tau, and neuron-specific enolase.
- Collection of tumor tissue during routine surgical resection for immunohistochemical and transcriptional analyses.
Serial evaluations will be performed preoperatively, postoperatively, at 72 hours, at 4 weeks, and 4 weeks following completion of radiotherapy, according to the assessment schedule.

Eksperymentalny: Blood Brain Barrier Characterisation Cohort
Participants with newly diagnosed glioblastoma will undergo a standardized Phase 2 multimodal assessment program designed to characterize blood-brain barrier integrity.
Study interventions include serial advanced contrast-enhanced MRI, blood biomarker sampling, neurocognitive assessments, and molecular analysis of tumor tissue obtained during standard of care surgical resection.
Assessments will be performed longitudinally at predefined time points before surgery, after surgery, at 72 hours, at 4 weeks, and following completion of radiotherapy to evaluate changes in blood-brain barrier function and their association with clinical, radiological, and molecular outcomes.
