   <abstract xml:lang="ru">
    <p>Актуальность. Метастатическое поражение головного мозга (ГМ) оказывает существенное негативное влияние на продолжительность жизни пациентов раком молочной железы (РМЖ). Ведется интенсивный поиск мультимодального подхода, который бы позволил разработать наиболее эффективные методы лечения метастатического поражения ГМ.&#13;
Материал и методы: В исследование включены 40 пациентов РМЖ, у которых при магнитнорезонансной томографии (МРТ) головного мозга диагностировано метастатическое поражение ГМ. В качестве основного метода лечения использовано тотальное облучение (ТО) ГМ до 30 Гр (3 Гр). Медиана возраста составила 48 (31 – 70) лет. В 75 % случаев установлен нелюминальный подтип РМЖ, у 57,5 % пациентов – РМЖ Т2, у 70 % пациентов – N0-1. &#13;
Результаты. Медиана продолжительности жизни после проведения ТО ГМ составила 12 (1 – 99) мес., 6–месячная выживаемость – 70 %, 12–месячная выживаемость – 47,5 %. Риск гибели достоверно повышался (HR=3,309; 95 % CI: 1,184 – 9,250, р=0,023) у пациентов, у которых временной интервал с момента манифестации 1-го рецидива до рецидива в ГМ составлял не более 24 мес. У таких пациентов продолжительность жизни составила всего 9,5 (1,0 – 96,0) месяцев и была достоверно ниже (р=0,0136), чем в группе, где аналогичный временной интервал составлял более 24 месяцев – 30 (2,0–99,0) месяцев. &#13;
Заключение. В результате проведенного исследования установлено, что эффективность ТО ГМ у пациентов с метастатическим поражением ГМ при РМЖ наиболее высокая в случае, если временной интервал с момента манифестации 1-го рецидива до метастатического поражения ГМ составляет более 24 мес.</p>

    <p>Purpose: Brain metastasis (BM) has a significant negative impact on the survival of breast cancer patients. An intensive search is underway for a multi-modal approach to identify the most effective methods of treating such patients. &#13;
Material and methods: The study included 40 patients with breast cancer who were diagnosed with BM on magnetic resonance imaging (MRI) of the brain. Total brain irradiation (TBI) up to 30 Gy (3 Gy) was used as the main treatment method. The median age was 48 (31–70) years. In 75 % of cases, a nonluminal subtype of breast cancer was found, in 57.5 % of cases–T2 breast cancer, in 70 % of cases–N0-1.&#13;
Results: The median survival after TBI was 12 months, 6-month survival rate was 70 %, and 12 – month survival rate was 47.5 %. The risk of death was significantly increased (HR=3.309; 95 % CI: 1,184 – 9,250, p=0.023) in patients whose time interval from the manifestation of 1 relapse to BM was ≤24 months. In these patients, the survival was only 9.5 months and was significantly lower (p=0.0136) than in the patients with the same time interval was &gt;24 months – 30 months.&#13;
Conclusions: It was found that the effectiveness of total brain irradiation in patients with breast cancer brain metastasis is the highest if the time interval from the moment of manifestation of first relapse to brain metastasis is more than 24 months.</p>
