Prospective Surgical Study on the Pattern of Electrical Activity in High Grade Glioma (WHO Grade III and IV) as a Predictor of Progression
Case Comprehensive Cancer Center
Summary
The purpose of this study is to test the safety and feasibility of recording brain activity within and around high-grade glioma tumors at the time of surgery. A small biopsy will be taken at the sites of the recordings.
Description
High-grade gliomas are incurable primary brain tumors. Recent data support that glioma cells can integrate within neuronal circuits. Glioma cells and neurons communicate via electrical impulses and chemically, through neurotransmitters. This crosstalk has been shown to promote glioma cell migration and invasion in preclinical models. However, the nature of the electrical activity and underlying molecular mechanisms are poorly understood. The long-term goal of this study is to determine the impact of high electrical activity and pattern of activity on tumor invasion, and mechanistic basis of it…

Inclusion Criteria: * Participants who have the appearance of high-grade glioma (HGG, WHO Grade 3 and 4, including GBM) on MR imaging are allowed to consent and will undergo the procedure if the frozen is consistent with HGG OR * Participants with a history of histologically-confirmed diagnosis of high- grade glioma that are undergoing resection of a recurrent/progressive tumor that is likely recurrent/progressive high- grade glioma as identified on preoperative MR imaging * Age ≥ 18 years old * Volumetric MRI within 1 month prior to surgery * Karnofsky performance status of 60 or higher *…
Interventions
- ProcedureStandard Surgical Treatment
During this surgery, participants will also undergo a tissue biopsy at recording sites for correlation to neural recording data.
- ProcedureIntraoperative Electrocorticography
Each participant will undergo intraoperative electrocorticography (ECOG) through subdural grid (SDG) and depth electrode (DE) via FDA-cleared, standardized, brain recording technology.
