Electrocorticography in Mapping Functional Brain Areas During Surgery in Patients With Brain Tumors

Study Purpose

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.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	18 Years and Over
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

- Patients undergoing a tumor resection at the University of Texas M.

D. Anderson Cancer Center for a newly diagnosed as well as recurrent primary or metastatic brain tumor located in or adjacent to motor and/or speech brain areas.

- Patients >= 18 years of age.

- Signed informed consent.

Exclusion Criteria:

- Patients with significant neurological motor deficits of the upper extremities, and/or speech deficits, which would preclude them from performing the while awake intra-operative tasks at the discretion of the principal investigator (PI) - Patients who have impaired vision and/or hearing and whose performance could affect the study will be excluded at the discretion of the PI

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT02754544
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	N/A

Additional Details

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 quantify new neurological deficits in the short term (24 hours) and long-term (1 and 3 months), and achieve a safe maximal tumor resection.

OUTLINE: Patients undergo tumor resection. During surgery, patients also undergo electrocorticography with either the CorTec high resolution hybrid grid, the PMT high-resolution grid, or the Ad-Tech grid followed by direct electrocortical stimulation. Following completion of study, patients are followed up within 24 hours from surgery and at 1 and 3 months.
