Using D-2-hydroxyglutarate in cerebrospinal fluid to track IDH‑mutant glioma

Intracranial D-2-Hydroxyglutarate as a Monitoring Biomarker for IDH-mutant Glioma.

NIH-funded research Mayo Clinic Rochester · NIH-11310742

This project will see if levels of a tumor chemical called D‑2‑hydroxyglutarate in spinal fluid can show how IDH‑mutant gliomas respond to treatment or come back.

What this research studies

If you join, researchers will collect cerebrospinal fluid (CSF) over time using routine lumbar punctures or existing clinical CSF access devices to measure D2‑HG levels. They will compare those CSF measurements to chemical levels found directly in the tumor tissue and in microdialysate taken during neurosurgery. The work is phased: an initial feasibility and discovery stage will refine the methods, followed by a validation stage to test the biomarker in more patients. The goal is to create a reliable, repeatable CSF test that tracks tumor activity without relying only on imaging.

Who could benefit from this research

Good fit: Ideal candidates are patients with confirmed IDH‑mutant glioma who are having neurosurgical care or are willing and able to provide serial CSF samples and tumor tissue samples.

Not a fit: People without IDH‑mutant tumors or those who cannot undergo CSF sampling or tumor sampling are unlikely to benefit from this biomarker approach.

Why it matters

Potential benefit: If successful, this could give doctors an earlier and more precise way to spot treatment response or tumor recurrence using a CSF test.

How similar studies have performed: Previous research links D2‑HG to IDH‑mutant tumors, but using CSF D2‑HG as a routine monitoring biomarker is relatively new and still needs clinical validation.
