Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study explores whether DESI-MS can be used to identify cancerous vs. noncancerous tissue during brain tumor surgery.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

PRIMARY OBJECTIVES:

I. To explore the translational abilities of desorption electrospray ionization mass spectrometry (DESI-MS) as intraoperative diagnostic tool to:

Ia. Identify cancerous versus noncancerous tissue and estimate the percentage of tumor infiltration in tissue biopsies, by monitoring depletion of N-acetylaspartate (NAA) and aberrations of the phospholipid signature of neurological tissue; Ib. Identify the presence of IDH mutations by monitoring the 2-hydroxyglutarate (2HG) and therefore differentiate between IDH-mutant and wild-type gliomas.

OUTLINE: This is an observational study.

Patients undergo tissue sample collection and DESI-MS during standard of care surgery and have their medical records reviewed on study. Patients also undergo MRI per standard of care on study.
