The combination of surgery, systemic therapy, whole brain irradiation and local methods of radiation therapy lead to good indicators for controlling the manifestations of the disease in the brain. Of course, intensification of treatment increases the risk of iatrogenic complications. The use of aggressive stereotactic radiotherapy regimens leads not only to high local control of irradiated metastases, but also to the risk of so-called radiation necrosis. The use of the most up-to-date diagnostic methods does not always allow one to unequivocally differentiate radiation necrosis from continued metastasis growth. The above example shows the need for a careful assessment of such situations and a multidisciplinary approach to interpreting the results of stereotactic radiotherapy.</p></abstract><trans-abstract xml:lang="ru"><p>Современные успехи онкологии позволяют значительно увеличить продолжительность жизни пациентов с метастатическим поражением головного мозга. Сочетание хирургических методов, системной терапии, облучения всего головного мозга и локальных методик лучевой терапии обеспечивает хороший контроль проявлений болезни в головном мозге. Разумеется, интенсификация лечения повышает риск развития ятрогенных осложнений. Применение агрессивных схем стереотаксической радиотерапии ассоциировано не только с высокими показателями локального контроля облученных метастазов, но и с риском развития постлучевого некроза. Использование самых современных диагностических методов не всегда дает возможность однозначно дифференцировать очаг постлучевого некроза и растущий метастаз. Приведенный в статье клинический пример иллюстрирует необходимость осторожной оценки подобных ситуаций и мультидисциплинарного подхода к интерпретации результатов стереотаксической радиотерапии.</p></trans-abstract><kwd-group xml:lang="en"><kwd>metastatic brain damage</kwd><kwd>breast cancer</kwd><kwd>stereotactic radiotherapy</kwd><kwd>radiation necrosis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>метастатическое поражение головного мозга</kwd><kwd>рак молочной железы</kwd><kwd>стереотаксическая радиотерапия</kwd><kwd>постлучевой некроз</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Mehta M.P., Tsao M.N., Whelan T.J. et al.
