Summary

This prospective study aims to characterize blood brain barrier (BBB) disruption in patients with newly diagnosed glioblastoma multiforme undergoing surgical resection. The study integrates advanced MRI, circulating BBB biomarkers, neurocognitive assessment, and molecular analysis of tumor tissue to investigate relationships between BBB integrity, tumor biology, and neurological function. Participants will undergo serial assessments before surgery, after surgery, and following radiotherapy. Tumor tissue collected during standard-of-care resection will undergo immunohistochemical and transcriptional

Multimodal Blood Brain Barrier Assessment

A standardised multimodal diagnostic assessment designed to characterize blood brain barrier integrity in patients with newly diagnosed glioblastoma. The intervention includes advanced contrast enhanced MRI, serial blood sampling for measurement of blood-brain barrier and neuronal injury biomarkers (including S100β, GFAP, UCHL1, amyloid beta, phosphorylated tau, and neuron-specific enolase), neurocognitive assessments, and immunohistochemical and transcriptional analyses of tumor tissue obtained during standard-of-care surgical resection. Assessments are performed longitudinally before surgery, after surgery, at 72 hours, at 4 weeks, and following completion of radiotherapy.
