Pilot Investigation of Using Electrocorticogram (ECoG) in Predicting Eloquent Cortex and Post-Operative Functional Outcomes in Patients With Brain Tumors
M.D. Anderson Cancer Center
Summary
This pilot clinical trial studies how well electrocorticography works in mapping functional brain areas during surgery in patients with brain tumors. Using a larger than the standard mapping grid currently used during brain tumor surgery or a high-definition grid for electrocorticogram brain mapping may help doctors to better identify which areas of the brain are active during specific limb movement and speech during surgery in patients with brain tumors.
Description
PRIMARY OBJECTIVE: I. To record electrocorticogram (ECoG) data intraoperatively with surface electrode grids during various motor, sensory (tactile) and speech tasks, and identify functional brain areas through the spectral analysis, and compare the preliminary data with our current pre-surgical mapping methods: functional magnetic resonance imaging (fMRI) and transcranial magnetic stimulation (TMS), and the gold standard, intraoperative direct electrical stimulation (DES). SECONDARY OBJECTIVE: I. To perform a preliminary assessment of the utility of using ECoG data in these patients to qua…
