Gliomas are brain tumors with high rates of recurrence and mortality. Early diagnosis of gliomas may be achieved by detecting the molecular biomarkers in body fluids [1]. It has been recently shown that one of specific markers for glioma differential diagnostics are enantiomers of 2-hydroxyglutarate (L-2HG and D-2HG), presented in brain tissues and blood. Blood constituents can be measured by THz, IR and Raman spectroscopy [2-4]. In this work, we use these methods, combined with machine learning, to study mouse blood plasma during glioblastoma development.

U87 human glioblastoma in the SCID line mice was created following the method described in [5]. Animals were excluded from the experiment at 7-th, 14-th, 21-st and 28-th day after tumor cells transplantation. Magnetic resonance spectroscopy has been used to identify glioma molecular markers at different stages of tumor growth [6]. A detailed description of the spectrometers was presented in our previous papers [2, 5].The spectral data analysis was conducted by the Principal Component Analysis, and multidimensional scaling. The prognostic models were developed by the linear kernel Support vector machine, Random forests, and Gradient boosting methods [4, 7]. A novel approach based on the Raman and absorption spectroscopy for detection of glioma molecular markers in blood is discussed.
