We prospectively evaluated number of recurrences, cosmetic effect and early treatment results of 104 patients with early breast cancer aged 66.72 ± 0.68 years old. The mean follow-up period was 36 months. The mean dose on the surface of applicator was 17.8 Gy, on the depth 0.5 cm – 8.8 Gy, on the depth 1.0 cm – 5 Gy. The mean time of radiation was 22.15 min ± 28.09 sec.</p><p><bold>Results.</bold> The local recurrence was in 3 patients. The first patient had triple negative breast cancer subtype, the second patient had luminal B HER2+, and the third one had luminal B HER2– subtype. Relapses occurred in 7, 14 and 20 months after the end of treatment respectively. The recurrence rate in patients with luminal B biological subtype was 10.71 %; in patients with triple negative subtype was 20 %. All recurrences were found in the area of the postoperative scar.</p><p><bold>Conclusion.</bold> The obtained results question the rationale for the use of the demonstrated method in patients with luminal B and triple negative molecular subtypes of tumors.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель работы</bold> – провести оценку непосредственных и отдаленных результатов лечения пациентов с ранним раком молочной железы с использованием методики интраоперационной лучевой терапии в зависимости от биологического подтипа опухоли.</p><p><bold>Материалы и методы.</bold> У 104 пациенток с ранним раком молочной железы в возрасте от 51 до 82 лет (медиана возраста – 66,72 ± 0,68 года) изучены показатели локального контроля. Среднее время наблюдения составило 36 мес. Средняя доза облучения на поверхности аппликатора составила 17,8 Гр, на глубине 0,5 см – 8,8 Гр, на глубине 1,0 см – 5 Гр. Среднее время облучения – 22,15 мин ± 28,09 с.</p><p><bold>Результаты.</bold> Локальный рецидив выявлен у 3 пациенток: 1-й – у больной с трижды негативным биологическим подтипом опухоли, 2-й – у пациентки с люминальным B HER2+ подтипом опухоли и 3-й – у женщины с люминальным B HER2– подтипом опухоли. Рецидивы возникли через 7, 14 и 20 мес после окончания лечения. Частота возникновения рецидивов у пациенток с люминальным B подтипом опухоли достигла 10,71 %, у женщин с трижды негативным подтипом опухоли – 20 %. Все указанные рецидивы были выявлены в области послеоперационного рубца.</p><p><bold>Выводы.</bold> Полученные результаты ставят под сомнение целесообразность использования рассматриваемой методики у пациентов с люминальным B и трижды негативным биологическими подтипами рака молочной железы.</p></trans-abstract><kwd-group xml:lang="en"><kwd>breast cancer</kwd><kwd>intraoperative radial therapy</kwd><kwd>biological subtype of breast cancer</kwd><kwd>recurrence</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак молочной железы</kwd><kwd>интраоперационная лучевая терапия</kwd><kwd>биологический тип опухоли</kwd><kwd>рецидив</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Cancer Incidence in Five Continents.
