Studying the Biology of IDH-mutant Gliomas Via Longitudinal Observation of 2-hydroxyglutarate (2-HG) Using MR Spectroscopy
Summary
Background: Glioma is a type of brain cancer. Some of these tumors have gene mutations. These mutations can cause a substance called 2-HG to build up in the brain. This makes the tumors more aggressive. Researchers want to better understand 2-HG buildup in the brain. They hope this can help them design better ways to test for gliomas. Objective: To monitor the level of 2-HG in the brains of people with gliomas that have mutations in the IDH1 or IDH2 genes. Eligibility: People ages 18 and older with gliomas with mutations in the IDH1 or IDH2 genes Design: Participants will be screened with: Medical and cancer history Physical exam Reviews of their symptoms and ability to perform normal activities Blood and urine tests MRI scan Samples of their tumor from a past surgery Documentation of their diagnosis and mutation status Participants will have an initial evaluation. This will include repeats of screening tests. It will also include: Neurological exam MRS and MRI scans of the brain: Participants will lie on a table that slides into a metal cylinder. A coil or soft padding will be placed around their head. They will have a contrast agent injected into a vein. Pictures will be taken of the brain. Participants will have follow-up visits every 2-6 month for the rest of their life. Visits will include scans.
