Отсутствие прогресса в лечении диффузных срединных глиом (ДСГ) привело к более частому проведению их биопсий с молекулярно-генетическим исследованием ткани опухоли для поиска новых терапевтических возможностей. Тем не менее последствия таких вмешательств пока изучены недостаточно.</p><p>Цель исследования – продемонстрировать нетипичный характер прогрессирования ДСГ ствола головного мозга у детей после открытой биопсии.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Проведен ретроспективный анализ данных 138 пациентов, пролеченных по поводу ДСГ в период с 2020 по 2024 г. Из данной когорты 38 пациентам с диффузной глиомой Варолиевого моста выполнена открытая биопсия с резекцией экзофитного компонента или опорожнением кисты. По демографическим показателям (пол, возраст) эти 38 больных существенно не отличалась от остальной части когорты. Биопсийный материал подвергался гистологическому и молекулярно-генетическому исследованию. Всем 138 пациентам выполняли лучевую терапию области опухоли, по показаниям – химиотерапию. Последующее динамическое наблюдение основывалось на оценке неврологического статуса и на данных МРТ ЦНС с применением контрастного усиления.</p></sec><sec><title>Результаты</title><p>Результаты. У 19 пациентов (50 % от 38 прошедших биопсию) по данным иммуногистохимического анализа послеоперационного материала была выявлена мутация К27М в гене H3F3A. У 6 (15 %) пациентов из 38 МРТ в сроки от 2 до 5 мес (медиана – 4,5 мес) после окончания лучевой терапии выявлено нехарактерное прогрессирование ДСГ в виде метастазирования по желудочковой системе головного мозга. У остальных пациентов когорты исследования, не проходивших процедуру биопсии, подобный характер прогрессирования не наблюдался (p&lt;0,002): у них, как правило, отмечался продолженный рост опухоли (n=96), у 4 больных диагностировано лептоменингеальное метастазирование по спинному мозгу.</p></sec><sec><title>Заключение</title><p>Заключение. Нами выявлены случаи нетипичного прогрессирования ДСГ в виде метастазирования по желудочковой системе у детей после открытой биопсии опухоли. Есть основания полагать, что биопсия могла способствовать диссеминации ДСГ по ликворным пространствам. Необходим поиск альтернативных методов оценки молекулярно-генетических характеристик ДСГ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. The lack of progress in the treatment of diffuse midline gliomas (DMG) has led to the increased use of biopsies with molecular genetic testing of tumor tissue to search for new therapeutic options. However, the consequences of frequent biopsies are not fully established. aim of the study: to demonstrate an atypical progression of brainstem DMG in children after open biopsy.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. A retrospective analysis of data from 138 patients treated for DMG between 2020 and 2024 was performed. Of the 138 patients included in this analysis, 38 patients with diffuse pontine glioma underwent open biopsy with exophytic component resection or cyst evacuation. In terms of the age and gender distribution, these 38 patients did not differ statistically from the rest of the patients. Biopsy samples were subjected to histological and molecular genetic examination. All 138 patients received radiotherapy to the tumor and chemotherapy, if indicated. Follow-up was based on the assessment of neurological status and contrast-enhanced MRI of the central nervous system.</p></sec><sec><title>Results</title><p>Results. Immunohistochemical analysis of surgical specimens revealed K27M mutation in the H3F3A gene in 19 patients (50 % of 38 who underwent biopsy). Atypical progression of DMG manifested as metastasis along the brain’s ventricular system was found in 6 out of 38 (15 %) patients within 2 to 5 months (median 4.5 months) after radiation therapy. In the remaining patients of the study cohort, who did not undergo a biopsy, a similar pattern of progression was not observed (p&lt;0.002): they, as a rule, had continued tumor growth (96 patients); leptomeningeal metastasis along the spinal cord was diagnosed in 4 patients.</p></sec><sec><title>Conclusion</title><p>Conclusion. Thus, we identified cases of atypical progression of DMG manifested as metastasis along the ventricular system in children after open tumor biopsy. There is reason to believe that biopsy could contribute to the dissemination of DMG throughout the liquor spaces. It is necessary to search for alternative methods for assessing the molecular genetic characteristics of DMGs.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>диффузная срединная глиома</kwd><kwd>биопсия</kwd><kwd>лучевая терапия</kwd><kwd>нетипичный характер метастазирования</kwd><kwd>нейроонкология</kwd><kwd>детская онкология</kwd><kwd>гистологическое исследование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>diffuse midline glioma</kwd><kwd>biopsy</kwd><kwd>radiation therapy</kwd><kwd>uncommon pattern of metastasis</kwd><kwd>neuro-oncology</kwd><kwd>pediatric oncology</kwd><kwd>histological processing</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">Stupp R., Brada M., van den Bent M.J., Tonn J.C., Pentheroudakis G.; ESMO Guidelines Working Group.
