Tumor Related Epilepsy

Study Purpose

Background: Some people with brain tumors have seizures related to the tumor. This is called tumor-related epilepsy. Usually brain tumors are treated by removing as much of the brain tumor as possible without causing problems. Researchers think this may improve the outcome for people with brain tumors. It may completely relieve or greatly reduce the number of seizures they have. Objectives: To evaluate people with brain tumors that are associated with seizures and to offer surgical treatment. Also, to study how surgery affects seizures. Eligibility: People age 8 and older who have a brain tumor with associated seizures. They must be willing to have brain surgery to treat their epilepsy. Design: Participants will be screened with a review of their medical records. Participants will have a medical history and physical exam. Participants will be admitted to the hospital at NIH. They will have Medical history Physical exam Neurological exam Tests of memory, attention, and thinking Questions about their symptoms and quality of life Blood drawn They may also have: MRI or CT scan. They will lie on a table that slides in and out of a machine that takes pictures. For part of the MRI, they will get a dye through an intravenous (IV) catheter. Video electroencephalography monitoring. Electrodes will be placed on the scalp. The participant s brain waves will be recorded while doing normal activities. Participants will be videotaped. Participants will keep a seizure diary before and after surgery. Participants will have surgery to remove their brain tumor and the brain area where their seizures start. They will stay in the hospital up to a week after surgery. Participants have for follow-up visits at NIH.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

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.

Eligible Ages 8 Years and Over
Gender All
More Inclusion & Exclusion Criteria

  • -


    To be eligible for entry into the study, a candidate must meet all the following criteria: - Be 8 years of age or older.
  • - Have solitary primary or recurrent brain tumor with associated seizures.
Brain tumor may be diagnosed radiologically. Associated seizures are defined as those with activity starting within three months of radiologic diagnosis of the primary or recurrent tumor. In cases when the timing of seizure activity is unclear with respect to the timing of diagnosis, seizures will be considered associated with the tumor if seizure semiology is consistent with that location. Ongoing seizures are not required. Patients can be included if they have had a single previous seizure. Patients who have not experienced seizures after institution of anti-convulsant therapy are not excluded.
  • - Agree to undergo brain surgery.
  • - Willing and able to appoint a durable power of attorney.


Candidates will be excluded if they:
  • - Have a bleeding disorder that cannot be corrected before invasive testing or surgery, or other medical conditions that would make surgery unsafe, such as lung or cardiac disease that would render them unable to tolerate the risk of general anesthesia, or severe immunodeficiency or systemic cancer not related to a brain lesion.
  • - Cannot have an MRI scan.
  • - Have multiple brain tumors, evidence of carcinomatous meningitis, gliomatosis cerebri, or primary CNS lymphoma.
Patients with multiple metastatic lesions that for which surgery is not indicated will be exluded. Patients with peripheral neurological or systemic metabolic disorders that cause seizures will be excluded.
  • - Have an underlying seizure disorder that is unrelated to the brain tumor, or underlying neurological disorder that is unrelated to the brain tumor and that may contribute to seizure activity.
  • - At the time of enrollment, lack consent capacity due to cognitive impairment that would make them incapable of understanding the explanation of the procedures in this study.
Cognitive capacity to consent will be determined at the time of enrollment. Patients with mental disorders or those patients who are cognitively impaired yet still retain consent capacity will not be excluded. Children may be enrolled if there is a parent or guardian able to consent on their behalf.

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.


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.

Additional Details

Objective This protocol is being performed to 1) study the natural history and disease pathogenesis in patients with tumor related epilepsy, 2) provide standard surgical treatment of brain tumors with associated seizures, 3) follow the clinical course of patients after surgical resection of brain tumors with associated seizures, such as outcomes in seizure activity as they relate to type of tumor and extent of resection, 4) investigate neuropsychological outcomes as they relate to surgical and seizure outcomes, 5) evaluate patient reported outcomes such as symptom burden changes as a result of surgical resection in patients with tumor-related epilepsy, 6) examine changes in structural and, when available, functional imaging in the context of tumor related epilepsy before and after surgical resection, 8) investigate molecular markers of tumor-related seizures in tumor and peritumoral specimens and, when available, to compare them to electrophysiological markers of tumor-related seizure activity. Study Population Patients 8 years and older with brain tumors and associated seizures may participate in this study. Study Design Patients will be screened by study neurosurgeon or neuro-oncologists to verify their confirmed or likely diagnosis of brain tumor and associated seizures. Patients confirmed to have a brain tumor with associated seizures will be offered standard diagnostic and surgical procedures. Non-invasive diagnostic procedures include structural MRI and neuropsychological and outcome assessments. Some patients may receive functional MRI when clinically indicated, which will be performed under a separate protocol, 14-N-0061, Non-invasive pre-surgical evaluation of patients with focal epilepsy. Invasive procedures include surgical resection of the brain tumor and associated epileptogenic region. The ultimate goal of surgical resection is to safely remove tumor tissue and to remove or modify the associated epileptic focus. Prior to tumor resection, diagnostic invasive monitoring with intracranial electrodes for further localization of seizure focus and identification of eloquent cortex may be clinically required. In these cases, invasive monitoring will be performed under a separte protocol, 11-N-0051 Epilepsy Surgery. Patients will be followed for three months after the surgical procedure and will receive standard neurological examinations and MRI evaluation of the brain as dictated by their care indicated for the brain tumor. Patients may also be seen at one year following surgery if medically stable and healthy. Participants in this protocol will not forego other standard treatments for their brain tumor, including chemotherapy and radiation treatment. Participation in this protocol will not preclude eligibility or participation in other NIH clinical trials. Outcome Measures The primary outcome measure is the change in seizure frequency, as measured by the Engel scale before and 3-6 months after treatment. Secondary outcome measures include 1) mean Engel Class three months after surgery stratified by the type of brain tumor and location and Engel scale, seizure frequency, and mean Engel Class one year after surgery stratified by the type of brain tumor and location; 2) extent of tumor and peri-tumoral resection as seen on MRI imaging and correlation with seizure outcome; 3) changes in neuropsychological assessment following surgical resection stratified by location and type of tumor and extent of resection; 4) longitudinal changes in symptom burden and interference scores using established instruments in brain tumor patients; 5) changes in structural imaging following surgical resection; 6) change in the use of anti-epileptic medication; and 7) percentage of patients with permanent neurological side-effects from surgical treatment.
