Comparing awake craniotomy and general anesthesia for glioblastoma surgery

Official title: The SAFE-Trial: Safe Surgery for Glioblastoma Multiforme: Awake Craniotomy Versus Surgery Under General Anesthesia. A Multicenter Prospective Randomised Controlled Study

Run by Erasmus Medical Center · NCT03861299 · Data updated 2026-11-12

This study is testing whether having brain surgery while awake is safer and more effective than having it under general anesthesia for people with glioblastoma in important areas of the brain.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 to 90 with a confirmed diagnosis of Glioblastoma Multiforme located in or near eloquent brain areas.

Probably not a fit

Patients with tumors in the cerebellum, brain stem, or midline, or those with multifocal lesions may not benefit from this study.

What this trial studies

This multicenter randomized controlled trial aims to evaluate the safety and efficacy of awake craniotomy versus surgery under general anesthesia in patients with Glioblastoma Multiforme located in eloquent brain areas. A total of 246 patients will be randomized into two groups: one undergoing awake craniotomy with cortical and subcortical stimulation, and the other receiving surgery under general anesthesia. The primary endpoints include the proportion of patients experiencing neurological deterioration post-surgery and the extent of tumor resection achieved. The study seeks to improve surgical outcomes and quality of life for patients with this aggressive brain tumor.

Why it matters

Potential benefit: If successful, this approach could lead to better surgical outcomes and improved quality of life for glioblastoma patients.

How similar studies have gone: Previous studies have shown that awake craniotomy can improve resection rates and preserve quality of life in low-grade gliomas, suggesting potential benefits for glioblastoma surgery as well.
