Brain activity study during surgery for high-grade glioma
Part of Cancer clinical trials.
This early-stage study measures electrical brain activity during brain tumor surgery to see if it can predict tumor return or progression. You may be offered the additional measurements while your surgeon removes a suspected or known high-grade glioma.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are age 18 or older.
- Your MRI shows a suspected high-grade brain tumor (grades 3 or 4, including glioblastoma) OR you have a confirmed history of high-grade glioma and you’re getting surgery for a recurrence/progression.
- You need a recent MRI scan within 1 month before surgery.
- You must be well enough for surgery (Karnofsky score 60 or higher).
- Your blood and clotting tests must be within safe ranges (or within the expected range if you’re on blood thinners).
- You must not be pregnant, and your tumor must not be in a brain area where the planned procedure would be too risky (certain critical “eloquent” areas).

This trial looks at a new imaging method to help doctors see brain tumors more clearly before surgery. It may help remove the tumor more safely and completely.
This study uses MRI scans to predict key genetic markers and outcomes in people with high-grade gliomas (aggressive brain tumors). If you are between 18 and 70 years old and have been diagnosed or are suspected of having a high-grade glioma, this research may help better understand your tumor without extra procedures.
This trial is testing a new way to find and remove glioblastoma brain tumors using a special MRI scan. It may help doctors remove more of the tumor safely during surgery.
This trial tests a technique called fluorescence-enhanced surgery to help surgeons see and remove high-grade gliomas more clearly. It uses a special dye (5-ALA) that makes tumor cells glow during surgery.
This study uses special MRI techniques to better understand how a high-grade brain tumor spreads into nearby brain tissue. The information may help doctors plan safer and more effective tumor removal.
This study looks at whether brain scans (MRI, PET/CT) can help predict the genetic makeup of glioblastoma, without needing more tissue samples. If you join, you'll get advanced imaging to better understand your tumor and guide future treatment decisions.
