Углубленное изучение вопроса позволит сформировать уточненные показания к использованию определенного режима лучевого лечения.</p><p>Цель исследования – оценка эффективности и безопасности методики гипофракционирования послеоперационной лучевой терапии РОД 2,7 Гр до СОД 40,5 Гр за 15 фракций в сравнении со стандартным режимом фракционирования.</p><sec><title>Материал и методы</title><p>Материал и методы. В исследование включена 321 пациентка с диагнозом рак молочной железы I–IIIA стадии, получавшая лечение в МРНЦ им. А.Ф. Цыба – филиал ФГБУ «НМИЦ радиологии» Минздрава России с 2013 по 2017 г. В первой группе послеоперационная лучевая терапия проводилась в режиме гипофракционирования с РОД 2,7 Гр до СОД 40,5 Гр за 15 фракций (n=223), вторую группу составили больные, получившие лечение в стандартном режиме РОД 2 Гр до СОД 50 Гр за 25 фракций (n=98). Обе группы сопоставимы по стадии заболевания, молекулярно-биологическому подтипу опухоли. Проведен статистический анализ основных характеристик изучаемых режимов. Результаты. При анализе не выявлено значимых различий в показателях общей и безрецидивной выживаемости в исследуемых группах. Частота ранних лучевых осложнений I и II степени в исследуемой и контрольной группах оказалась сопоставима, 79 и 84 % соответственно. Поздние лучевые повреждения I и II степени развивались реже (p&lt;0,01) у больных, получивших лучевую терапию в режиме гипофракционирования (23 %), чем в контрольной группе (43 %). Тяжелые постлучевые повреждения нормальных тканей не наблюдались. Объём хирургического лечения не повлиял на отдаленные результаты лечения.</p></sec><sec><title>Выводы</title><p>Выводы. Полученные данные свидетельствуют о преимуществе методики гипофракционирования по показателям поздней лучевой токсичности, при одинаковых показателях выживаемости. Также исследуемый режим удобен для самих пациентов и превосходит по экономической рентабельности. Необходимо дальнейшее исследование ускоренных режимов фракционирования послеоперационной лучевой терапии РМЖ, которое позволит оптимизировать результаты лечения одной из ведущих онкопатологий.</p></sec></abstract><trans-abstract xml:lang="en"><p>The purpose of the study was to evaluate the efficacy and safety of hypofractionated postoperative radiation therapy (2.7 Gy per fraction in 15 fractions to a total dose of 40.5 Gy) in comparison with the standard fractionation regimen.</p><sec><title>Material and methods</title><p>Material and methods. The study included 321 patients diagnosed with stage I–IIIA breast cancer treated in the A. Tsyb Medical Radiological Research Center from 2013 to 2017. The patients were divided into two groups. Group I patients received hypofractionated postoperative radiotherapy at a total dose of 40.5 Gy in 15 fractions with Gy 2.7 Gy/fraction (n=223). Group II patients received conventional radiotherapy at a total dose of 50 Gy in 25 fractions with 2 Gy/fraction (n=98). Both groups were comparable in terms of the stage of the disease and molecular subtype of the tumor. The statistical analysis of the main characteristics of the studied regimens was carried out.</p></sec><sec><title>Results</title><p>Results. The analysis revealed no significant differences in the overall survival (OS) and disease-free survival (DFS) between two groups. The frequency of acute radiation-induced complications (grade 1 and 2) in Groups I and II were 79 % and 84 %, respectively. Late radiation-induced side effects were observed less frequently in patients treated with hypofractionated postoperative radiotherapy than in the control group patients (23 % versus 43 %, p&lt;0.01). Severe post-radiation damage to normal tissues was not found. The extent of surgery did not affect the long-term treatment outcomes.</p></sec><sec><title>Conclusion</title><p>Conclusion. Comparison of hypofractionated radiotherapy with conventional radiotherapy in breast cancer patients demonstrated the superiority of hypofractionated radiotherapy regimen in terms of late toxicity and economic profitability. Further studies of accelerated fractionated postoperative radiotherapy are required to improve the treatment outcomes in breast cancer patients.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>лучевая терапия</kwd><kwd>гипофракционирование</kwd><kwd>рак молочной железы</kwd><kwd>адъювантное лечение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>radiation therapy</kwd><kwd>hypofractionation</kwd><kwd>breast cancer</kwd><kwd>adjuvant treatment</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">Каприн А.Д., Старинский В.В., Петрова Г.В.
