What this trial studies

This international, multicenter, prospective observational cohort study aims to compare the effects of tumor resection versus best oncological treatment for patients with recurrent glioblastoma. Patients will be assigned to either treatment option at a 1:1 ratio based on a tumor board decision. The study will evaluate primary endpoints such as NIHSS deterioration at 6 weeks post-surgery and overall survival, along with secondary endpoints including progression-free survival and various functional assessments. The study will utilize intraoperative mapping techniques to enhance safety during resection.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 90 with recurrent glioblastoma suitable for resection.

Not a fit: Patients with tumors located in the cerebellum, brainstem, or midline, or those unable to provide informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the optimal treatment approach for recurrent glioblastoma, potentially improving patient outcomes.

How similar studies have performed: Previous studies have shown mixed results regarding the benefits of resection for recurrent glioblastoma, making this approach both relevant and necessary for further investigation.
