A Study to Evaluate Advanced Development of Desorption Electrospray Ionization Mass Spectrometry for Intraoperative Molecular Diagnosis of Brain Cancer

Overview

About this study

The purpose of this study is to explore the translational abilities of desorption electrospray ionization mass spectrometry (DESI-MS) as intraoperative diagnostic tool to 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; and to identify the presence of IDH mutations by monitoring the 2-hydroxyglutarate (2HG) and, therefore, differentiate between IDH-mutant and wild-type gliomas.
