Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The study is designed as an international, multicenter prospective cohort study. Patients with presumed glioblastoma (GBM) in- or near eloquent areas on diagnostic MRI will be selected by neurosurgeons. Patients will be treated following one of three study arms: 1) a craniotomy where the resection boundaries for motor or language functions will be identified by the "awake" mapping technique (awake craniotomy, AC); 2) a craniotomy where the resection boundaries for motor functions will be identified by "asleep" mapping techniques (MEPs, SSEPs, continuous dynamic mapping); 3) a craniotomy where the resection boundaries will not be identified by any mapping technique ("no mapping group"). All patients will receive follow-up according to standard practice.
