Согласно классификации опухолей ЦНС ВОЗ гемистоцитарные астроцитомы (ГА) являются вариантом астроцитарных опухолей, у которых доля гемистоцитов составляет не менее 20 % от общей клеточной массы. Морфо-молекулярная характеристика и тактика лечения ГА определены недостаточно.</p></sec><sec><title>Цель</title><p>Цель. Выявление факторов риска развития раннего рецидива гемистоцитарных астроцитом (ГА).</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Выполнен ретроспективный и проспективный анализы клинических характеристик, данных МРТ головного мозга, особенностей морфологических и молекулярно-генетических 14 пациентов с диагнозом ГА. В работу были включены больные старше 18 лет с супратенториальной локализацией опухоли. Больные были в возрасте от 27 до 62 лет, медиана возраста составила 35,5 лет. Мужчин было 5. После операции проводились гистологическое, иммуногистохимическое и молекулярно-генетическое исследования. Гистологический диагноз ставился в соответствии с классификацией опухолей ЦНС ВОЗ (2016) и атласом AFIP (2007). Методом ПЦР в режиме реального времени у всех пациентов выявляли наличие мутации в генах IDH1/IDH2 и сочетанной делеции 1p19q, и у 10 больных также определяли уровень экспрессии генов: TP, VEGF, PDGFRA, β-tubulin, MGMT, C-kit, ERCC1.</p></sec><sec><title>Результаты</title><p>Результаты. Медиана безрецидивного периода (БРП) ГА составила 89 недель. В случае наступления рецидива до этого срока, БРП условно считался ранним. Произведен расчет отношения шансов (OR) различных параметров в группах раннего и позднего рецидива по стандартной методике. Достоверно риск развития раннего рецидива ГА повышался при экспрессии гена VEGF ΔСt &lt; 1,15 (p &lt; 0,05) (OR — 121). Также выявлено еще несколько факторов риска, которые способствовали раннему рецидиву ГА, но без статистической достоверности: экспрессия гена β-tubulin ΔСt &lt; 0,65 (ОR — 33), накопление контраста опухолью по МРТ головного мозга (OR — 10,7), пролиферация сосудов (OR — 8,3), Ki-67 &gt; 5 % (OR — 4,5), распространение опухоли в глубокие отделы полушарий головного мозга (OR — 4,5).</p></sec><sec><title>Заключение</title><p>Заключение. Особенности данных МРТ головного мозга, морфологической и молекулярно-генетической картины ГА позволили сформировать группу больных с высоким риском развития раннего рецидива опухоли. Эти пациенты, вероятно, нуждаются в проведении комплексного лечения (операция, лучевая терапия, химиотерапия), которое в настоящее время им, как правило, не проводится.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. According to the WHO CNS of tumors of central nervous system gemistocytic astrocytomas (GA) are common astrocytic tumors, in which the proportion of gemistocytes is at least 20 % of the total cell mass. Morpho-molecular characterization and treatment tactics of GA research is insufficient.</p></sec><sec><title>Purpose</title><p>Purpose. Identification of risk factors for the development of early recurrence of gemistocytic astrocytes (GA).</p></sec><sec><title>Material and methods</title><p>Material and methods. A retrospective and prospective analysis of the identified signs, brain MRI data, features of morphological and molecular genetic diseases was performed in 14 patients diagnosed with GA. The work included patients older than 18 years with supratentorial invasive tumor. The patients were aged 27 to 62 years, the average temperature of the age was 35.5 years. There were 5 men. After the removal operation, histological, immunohistochemical and molecular genetic studies were performed. The histological diagnosis was made according to the WHO classification of CNS tumors and the AFIP atlas (2007). Real-time PCR revealed the presence of mutations in the IDH1/IDH2 genes and the combined deletion of 1p19q in all patients; in 10 patients, the level of gene expression was also observed: TP, VEGF, PDGFRA, β-tubulin, MGMT, C-kit, ERCC1.</p></sec><sec><title>Results</title><p>Results. Median recurrence-free period (RFS) GA was 89 weeks. If a recurrence occurs before this time RFS is considered early. The odds ratio (OR) was calculated for different groups of early and late recurrence according to the standard method. Significantly, the risk of developing an early relapse of GA increased with the expression of the VEGF gene, ΔSt &lt; 1.15 (p &lt; 0.05) (OR — 121). Several risk factors were also identified that cause inflammation of GA recurrence, but without a statistical tumor: expression of the β-tubulin gene ΔSt &lt; 0.65 (RR — 33), accumulation of tumor contrast. according to MRI of the brain (OR — 10.7), vascular proliferation (OR — 8.3), Ki-67 &gt; 5 % (OR — 4.5), tumor spread in the area of opening of the cerebral hemispheres (OR — 4.5).</p></sec><sec><title>Conclusion</title><p>Conclusion. Features of brain MRI data, morphological and molecular-genetic picture These patients probably need complex treatment (surgery, radiation therapy, chemotherapy), which they currently do not meet.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>гемистоцитарная астроцитома</kwd><kwd>гистология</kwd><kwd>глиома</kwd><kwd>молекулярно-генетические особенности</kwd><kwd>ранний рецидив</kwd><kwd>факторы риска</kwd></kwd-group><kwd-group xml:lang="en"><kwd>early recurrence</kwd><kwd>gemistocytic astrocytoma</kwd><kwd>glioma</kwd><kwd>histology</kwd><kwd>molecular genetic features</kwd><kwd>risk factors</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">Хачатрян В.А., Улитин А.Ю., Самочерных К.А. и др.
