Is this trial a fit for you?

Likely a good fit

Ideal candidates are adult patients with a brain lesion suspected to be GBM who are eligible for gross total tumor resection.

Probably not a fit

Patients under 18 years old, those with liver disease, severe anemia, or who are pregnant may not benefit from this study.

What this trial studies

This observational study focuses on glioblastoma multiforme (GBM), the most aggressive type of primary brain tumor. It aims to analyze the levels of glutamate and its related enzymes in serum and cerebrospinal fluid (CSF) to understand their role in tumor growth and invasion. A total of 40 patients suspected of having GBM will undergo blood sampling and MRI imaging at baseline and during follow-up at 3, 6, and 9 months. The study will collect molecular biology data alongside oncological and imaging information to explore potential therapeutic targets.

Why it matters

Potential benefit: If successful, this study could lead to new therapeutic approaches targeting glutamate signaling in glioblastoma treatment.

How similar studies have gone: While the role of glutamate in glioblastoma is being explored, this specific approach of measuring glutamate levels as biomarkers is relatively novel.
