Recording brain activity during surgery for high grade glioma
Original title: Prospective Surgical Study on the Pattern of Electrical Activity in High Grade Glioma as a Predictor of Progression
How far along is this research?
This is a trial that is enrolling or has been updated. It is not a finding yet.
This is an early safety test in people, so it is far from being regular care.
Status: Recruiting. It is looking for patients now. Talk to your care team about whether it fits you.

The short version
This study looks at whether doctors can safely record electrical activity in and around a high grade glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are graded 1 to 4 by how fast they tend to grow. See the glossary while a person is having surgery.
Who this trial is for. This study is for people having surgery for a high grade glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are graded 1 to 4 by how fast they tend to grow. See the glossary. It tests whether it is safe and workable to record the brain's electrical activity inside and near the tumor during that surgery. A small biopsy is taken at the spots where the recordings are made.
Where it stands. There are no results yet. The study is measuring safety and whether the recording can be done during surgery. Researchers also want to see if the pattern of electrical activity says anything about how the tumor may grow. The answers are not in yet.
What this means, and what it doesn't
What it could mean: For now, this is a way researchers are trying to learn more about high grade glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are graded 1 to 4 by how fast they tend to grow. See the glossary. It does not change any treatment today. Someone who is facing surgery for a high grade glioma could ask their care team whether a study like this is worth talking about.
What it doesn't mean: This does not mean a new treatment has been found. A trial is a test, not proven care. Joining a trial is not a guarantee that it will help you. It is not a promise of a cure. Whether anyone can join is decided by the trial team.
