В работе проанализированы возможности флуоресцентной диагностики для глиом низкой степени злокачественности с использованием хлорина е6. В исследование были включены пациенты с впервые диагностированной глиомой низкой степени злокачественности (low-grade glioma, LGG), у которых с целью интраоперационного флуоресцентного контроля применен препарат хлорин е6 в дозе 1 мг/кг массы тела. В процессе операции анализировали интенсивность флуоресценции различных участков предполагаемой опухолевой ткани с использованием программного обеспечения RSS Cam – Endo 1.4.313. Образцы тканей различной степени интенсивности флуоресценции сопоставляли с результатами их гистопатологического анализа (диагностика опухоли ВОЗ, индекс Ki-67, P53, VEGF). Флуоресценция выявлена в более чем половине случаев, но в большинстве случаев имела очаговый характер и низкую интенсивность флуоресценции. Интенсивность флуоресценции напрямую коррелировала с данными гистопатологического исследования тканей опухоли: индекс Ki-67 (p=0,002), экспрессия P53 (p=0,0015), VEGF (p=0,001). Чувствительность метода для хирургии LGG составила 72%, специфичность 56,7%. Проведенное исследование подтвердило, что технология интраоперационной флуоресцентной диагностики с применением хлорина е6 может применяться в хирургии LGG, особенно для визуализации внутриопухолевых участков с более высокой степенью анаплазии.</p></abstract><trans-abstract xml:lang="en"><p>Intraoperative fluorescence diagnostics of high-grade gliomas is widely used in neurosurgical practice. This work analyzes the possibilities of fluorescence diagnostics for low-grade gliomas (LGG) using chlorin e6 photosensitizer. The study included patients with newly diagnosed LGG, for whom chlorin e6 was used for intraoperative fluorescence control at a dose of 1 mg/kg. During the operation, the fluorescence intensity of various areas of the putative tumor tissue was analyzed using the RSS Cam – Endo 1.4.313 software. Tissue samples with various degrees of fluorescence intensity were compared with the results of their histopathological analysis (WHO tumor diagnosis, Ki-67 index, P53, VEGF). Fluorescence was detected in more than half of the cases, but in most cases had a focal character and low fluorescence intensity. The fluorescence intensity directly correlated with the data of histopathological examination of tumor tissues (Ki-67 index (p=0.002), expression of P53 (p=0.0015) and VEGF (p=0.001)). The sensitivity of the method for LGG surgery was 72%, the specificity was 56,7%. Intraoperative fluorescence diagnostics with chlorin e6 can be used in LGG surgery, especially to visualize intratumoral areas with a higher degree of anaplasia.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>глиомы низкой степени злокачественности</kwd><kwd>хлорин е6</kwd><kwd>интраоперационная флуоресцентная диагностика</kwd><kwd>нейроонкология</kwd></kwd-group><kwd-group xml:lang="en"><kwd>low-grade gliomas</kwd><kwd>chlorin e6</kwd><kwd>intraoperative fluorescence diagnostics</kwd><kwd>neurooncology</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Diwanji T.P., Engelman A., Snider J.W., Mohindra P.
