На 2020 г. заболеваемость раком молочной железы в России составила 11,8 % среди всех онкологических патологий и 21,7 % опухолей, выявляемых у женщин. При этом частота метастазирования в головной мозг оценивается в 13–32 %. Имеются данные, что HER2‑положительный и трижды негативный подтипы рака молочной железы более склонны к метастазированию в головной мозг по сравнению с другими.</p><p>Цель исследования – представление случая проведения высокодозного стереотаксического облучения крупного метастаза HER2‑положительного рака молочной железы в стволе головного мозга и повторного облучения рецидива этого метастаза с локальным контролем через 5 лет и отсутствием у пациентки неврологических нарушений.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведен анализ результатов стереотаксической лучевой терапии крупного метастаза в стволе головного мозга и повторной стереотаксической лучевой терапии на рецидив ранее облученного очага с локальным контролем через 5 лет.</p></sec><sec><title>Результаты</title><p>Результаты. На момент осмотра через 5 лет после начала лечения состояние пациентки оценивается в 100 баллов по шкале Карновского, по данным контрольных инструментальных исследований признаков продолженного роста, лучевого некроза не выявлено.</p></sec><sec><title>Заключение</title><p>Заключение. Представленное клиническое наблюдение иллюстрирует необходимость детального определения границ опухоли на основании данных магнитно‑резонансной томографии с высоким разрешением, высокоточного конформного подведения дозы облучения в режиме гипофракционирования и верификации рецидива по данным позитронно‑эмиссионной томографии. Возможное синергичное влияние таргетной терапии требует дальнейшего изучения.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Breast cancer contributed to 11.8 % of all the oncological diseases detected in Russia in 2020 and to 21.7 % of tumors detected among women. The frequency of brain metastases is estimated at 13–32 %. It is known that HER2 positive and triple negative breast cancers metastasize to the brain more frequently.</p></sec><sec><title>Aim</title><p>Aim. To present the case of stereotactic high‑dose irradiation for a large brainstem metastasis from HER2 positive breast cancer and re‑irradiation of the recurrence.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Analysis of the results of stereotactic irradiation for a large brainstem metastasis from HER2 positive breast cancer and re‑irradiation of the recurrence with a local control over five years was performed.</p></sec><sec><title>Results</title><p>Results. The local control after five years did not show any signs of tumor progression or post‑radiation necrosis. The patient’s Karnofsky Performance Status was estimated at 100 points.</p></sec><sec><title>Conclusions</title><p>Conclusions. The case shows the necessity of highly conformal stereotactic dose delivery to the tumor, precise determination of tumor boundaries on high resolution thin slice magnetic resonance imaging, verification of recurrence using metabolic studies and hypofractionated dose delivery. It remains open whether and to what extent target therapy may contribute to local control.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>метастазы в ствол головного мозга</kwd><kwd>облучение рецидива</kwd><kwd>рак молочной железы HER2‑положительный</kwd><kwd>гипофракционирование</kwd><kwd>радиохирургия</kwd><kwd>КиберНож</kwd></kwd-group><kwd-group xml:lang="en"><kwd>brainstem metastases</kwd><kwd>re‑irradiation of recurrence</kwd><kwd>HER2‑positive breast cancer</kwd><kwd>hypofractionated radiotherapy</kwd><kwd>radiosurgery</kwd><kwd>Cyber Knife</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">Злокачественные новообразования в России в 2020 году (заболеваемость и смертность).
