Детальное изучение коллагена как перспективного биомаркера злокачественности весьма актуально для дополнения к гистопатологии в точной диагностике и планировании лечения. В данном исследовании предлагается подход к детекции коллагена в тканях внутричерепных опухолей методом спектроскопии спонтанного комбинационного рассеяния с возбуждением на длине волны 785 нм.</p></abstract><trans-abstract xml:lang="en"><p>As brain tumors progress, excess collagen increases the rigidity of the extracellular matrix, which promotes metastasis, impedes drug penetration, and reduces the effectiveness of therapy. A detailed study of collagen as a promising biomarker of malignancy is highly relevant for complementing histopathology for accurate diagnosis and treatment planning.
