В настоящее время один из эффективных методов лечения внутричерепных метастазов – стереотаксическая радиохирургия. Основные факторы, ограничивающие применение данного метода: размер (объем) опухоли или расположение метастаза в критической близости к радиочувствительным структурам головного мозга (зрительные пути, таламус, ствол головного мозга), в которых риск развития локального лучевого некроза высок. Для снижения риска побочных эффектов облучения используется гипофракционированная лучевая терапия линейными ускорителями или стажированная (этапная) радиохирургия аппаратом «Гамма-нож». Однако крупные метастазы в головной мозг, вызывающие дислокацию срединных структур головного мозга, традиционно считаются объектом для хирургического удаления, основная цель которого – устранение масс-эффекта, вызванного опухолью.</p></sec><sec><title>Цель публикации</title><p>Цель публикации: представить случай успешного применения этапной радиохирургии гамма-ножом в лечении крупных метастазов в головной мозг, сопровождающихся выраженным перифокальным отеком и дислокацией мозговых структур.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Пациентке, 38 лет, с правосторонней гемиплегией (0 баллов) и крупным (Ø = 3 см, V = 12,9 см3) метастазом рака молочной железы в глубинных отделах левого полушария, сопровождавшимся выраженным перифокальным отеком и дислокацией мозговых структур (15 мм), успешно проведена этапная радиохирургия с помощью аппарата «Гамма-нож» в 2 этапа с интервалом 1,5 мес.</p></sec><sec><title>Результаты</title><p>Результаты. В результате лечения отмечен не только полный регресс перифокального отека и смещения срединных структур, но и значимое уменьшение объема опухоли, а также существенное улучшение неврологического статуса больной уже в промежутке между этапами радиохирургии – восстановление активных движений в правых конечностях до 4 баллов.</p></sec><sec><title>Заключение</title><p>Заключение. Данный случай демонстрирует возможность эффективного и безопасного неинвазивного лечения крупных метастазов в головной мозг, сопровождающихся компрессией и дислокацией головного мозга, которое позволяет добиться регресса масс-эффекта и улучшить неврологическое качество жизни онкологических больных.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Currently, one of the effective methods of treatment of intracranial metastases is stereotactic radiosurgery. The main factors limiting its use are the size (volume) of the tumor or the location of the metastasis in critical proximity to radiosensitive brain structures, such as the optic pathways, thalamus, brain stem, due to the high risk of developing local radiation necrosis. To reduce the risk of adverse radiation effects, hypofractionated radiotherapy by linac or staged Gamma Knife radiosurgery is used. However, large brain metastases that cause dislocation of the brain midline structures are traditionally considered an object for surgical excision, the main purpose of which is to eliminate the mass effect caused by the tumor.</p><p>The objective of the publication: to demonstrate a case of successful application of staged Gamma Knife radiosurgery of large brain metastases accompanied by brain compression and dislocation.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Patient, 38‑year-old, with right-sided hemiplegia (0 score) and large (Ø = 3 cm, V = 12.9 cm3) breast cancer metastasis in the deep site of the left hemisphere, accompanied by severe perifocal edema and braindislocation (midline shift up to 15 mm). The treatment was carried out by Gamma Knife in two stages with an interval of 1.5 months.</p></sec><sec><title>Results</title><p>Results. As a result, not only a complete regression both of the perifocal edema and midline shift were noted, but also a significant decrease of the tumor volume and dramatical improvement in the patient’s neurological status already in the interval between the stages of radiosurgery: restoration of active movements in the right limbs (up to 4 score).</p></sec><sec><title>Conclusion</title><p>Conclusion. This case demonstrates the possibility of effective and safe non-invasive treatment of large brain metastases accompanied by brain compression and dislocation, which makes it possible to achieve regression of the mass effect and improve the neurological quality of life of cancer patients.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>стереотаксическая радиохирургия</kwd><kwd>метастазы в головной мозг</kwd><kwd>масс-эффект</kwd><kwd>сдавление и дислокация мозга</kwd><kwd>качество жизни</kwd></kwd-group><kwd-group xml:lang="en"><kwd>stereotactic radiosurgery</kwd><kwd>brain metastases</kwd><kwd>mass-effect</kwd><kwd>midline shift</kwd><kwd>quality of life</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">Банов С.М., Голанов А.В., Ильялов С.Р. и др.
