Известно о взаимосвязи опухоли с микроокружением, а ее стромальные характеристики лежат в основе опухолевой прогрессии. целью исследования было изучение характера мезенхимальной стромы глиом высокой степени злокачественности. проведено ретроспективное исследование биопсийного материала астроцитарных опухолей категории G4, диагностированных в российском научно-исследовательском нейрохирургическом институте им. проф. А.л. Поленова у 31 пациента. В 10 случаях верифицирована астроцитома с мутантной версией гена IDH, в 21 - глиобластома с IDH дикого типа. Качественные характеристики стромы опухолей оценивали с помощью иммуногистохимических реакций с антителами к IDH1R132h и виментину, гистохимических окрасок альциановым синим, толуидиновым синим, трихромом по Мэллори, импрегнации серебром по Футу. Анализ результатов выявил значимые различия между группами (р &lt;0,05) при всех вариантах гистохимической окраски. Наличие опухолевой стромы с десмоплазией и высокая экспрессия виментина указывают на глиально-мезенхимальный переход в глиобластомах с IDH дикого типа, лежащий в основе опухолевой прогрессии.</p></abstract><trans-abstract xml:lang="en"><p>Gliomas are characterized by extremely aggressive growth and resistance to therapy. The tumor progression is known to be closely linked to its microenvironment, with stromal characteristics playing a key role. The aim of the study was to investigate the features of mesenchymal stroma in high-grade gliomas. A retrospective study was conducted on biopsy specimens from 31 patients with grade 4 astrocytic tumors at the A. L Polenov Russian scientific Research Institute of Neurosurgery. Based on molecular profiling, 10 patients were diagnosed with IDH-mutant astrocytoma, and 21 patients were diagnosed with IDH-wildtype glioblastoma. The tumor stroma was assessed using immunohistochemical (IHc) staining for IDH1R132h and vimentin and histochemical staining with Alcian Blue, Toluidine Blue, and Mallory's trichrome. analysis revealed statistically significant differences between the groups for all histochemical stains (p &lt;0.05, student's t-test). The presence of desmoplastic stroma and high vimentin expression indicates a glial-mesenchymal transition in IDH-wildtype glioblastoma, which underlies its aggressive progression.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>астроцитома</kwd><kwd>глиобластома</kwd><kwd>мутантный IDH</kwd><kwd>IDH дикого типа</kwd><kwd>микроокружение</kwd><kwd>строма</kwd><kwd>эпителиально-мезенхимальный переход</kwd></kwd-group><kwd-group xml:lang="en"><kwd>astrocytoma</kwd><kwd>glioblastoma</kwd><kwd>IDH mutant</kwd><kwd>wildtype IDH</kwd><kwd>microenvironment</kwd><kwd>stroma</kwd><kwd>epithelial-mesenchymal transition</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">Чойнзонов Е.Л., Грибова О.В., Старцева Ж.А. и др.
