Trial Completed: Rare CNS Tumors Outcomes &Risk (NCT03251989)
Researchers at the National Cancer Institute completed a study of 326 people with rare brain and spine tumors, including meningioma, ependymoma, medulloblastoma, and other types. The study collected health information and genetic data to understand what causes these tumors to develop and what factors increase the risk of getting them. These tumors are very uncommon, affecting fewer than 2,000 people per year in the United States.
