Escalation of radiation dose, larger daily fractions radiation therapy (including high-dose-rate interstitial brachytherapy (HDR-BT)) is a promising approach to the treatment of PCa.</p><p><bold>Objective of the study</bold>. Comparative assessment of the long-term treatment results of patients with PCa with a poor prognosis after external beam radiotherapy (EBRT) and combined radiation therapy, depending on risk factors.</p><p><bold>Materials and methods</bold>. 207patients who received a course EBRT and HDR-BT with EBRT (combined RT) on a radical program for the first detected PCa at the N.N. Alexandrov National Cancer Center of Belarus in 2013—2015 inclusive. All patients were belonged to the group of</p><p>high and very high risk of progression according to the criteria of the NCCN (National Comprehensive Cancer Network), all were treated with neoadjuvated hormone therapy (medical or surgical castration).</p><p>The patients were stratified into two groups: HDR-BT with EBRT and EBRT. When conducting combined RT, HDR-brachytherapy was performed in single fraction with a dose of 11.5 Gy, for EBRT it was used as a conventional fractionation (single dose of 2 Gy, total — 44 Gy) and hypofractionation (single dose of 3 Gy, total — 36 Gy). Patient that were not who not included in the combined RT protocol were treated with EBRT under a radical program in a total dose of 78—80 Gy.</p><p><bold>Results</bold>. It was established that in the group of patients after EBRT the median survival was not achieved, the 5-year adjusted survival (AS) was 85.2 + 5.6 %. In the combined RT group, the median survival was also not reached, the 5-year-old AS was 92.2 + 5.9 %. It was found that for the patients with a Gleason score of 7 or more, a significant difference in the AS index was obtained in favor of the HDR-BT with EBRT: the 5-year AS of patients of this subgroup who were exposed to combined RT was 84.6 + 9.8 %, while after EBRT, the 5-year-old AS was 71.0 + 11.2 %. In the subgroup of patients with Gleason sum 7—10, combined RT was associated with statistically significantly better long-term results in compared with EBRT.</p><p><bold>Conclusion.</bold>The application of the method of combined RTfor patients suffering from PCa with a high risk is characterized with satisfactory long-term treatment results.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Пациенты, страдающие раком предстательной железы (РПЖ) с высоким риском прогрессирования, нуждаются в наиболее активной лечебной тактике. Эскалация дозы облучения и крупнофракционное облучение (в том числе внутритканевая брахитерапия высокой мощности дозы) являются перспективным подходом к лечению РПЖ.</p><p><bold>Цель исследования</bold> — сравнительная оценка отдаленных результатов лечения пациентов, страдающих РПЖ с неблагоприятным прогнозом, после дистанционной лучевой терапии (ДЛТ) и сочетанной лучевой терапии (СЛТ) в зависимости от факторов риска.</p><p><bold>Материалы и методы</bold>. В РНПЦ ОМР им. Н.Н. Александрова в 2013—2015 гг. 207пациентов получили курс ДЛТ и СЛТ по радикальной программе по поводу впервые выявленного РПЖ. Все пациенты относились к группе высокого и крайне высокого риска прогрессирования согласно критериям NCCN (National Comprehensive Cancer Network), всем проводилась неоадъювантная гормонотерапия (медикаментозная или хирургическая кастрация).</p><p>Пациентов стратифицировали на 2 группы: 1-я группа получила курс СЛТ, 2-я — ДЛТ. При проведении СЛТ контактная лучевая терапия выполнялась однократно в дозе 11,5Гр, для дистанционного облучения использовался как стандартный режим фракционирования дозы (разовая доза 2 Гр, суммарная — 44 Гр), так и режим гипофракционирования (разовая доза 3 Гр, суммарная — 36 Гр). Пациентам 2-й группы выполнялась ДЛТ по радикальной программе в суммарной очаговой дозе 78—80 Гр.</p><p><bold>Результаты.</bold> В 1-й и 2-й группах медиана выживаемости не была достигнута, 5-летняя скорректированная выживаемость составила 92,2 + 5,9 и 85,2 + 5,6 % соответственно. У пациентов с суммой баллов по шкале Глисона &gt;7получена существенная разница в показателе скорректированной выживаемости в пользу сочетанного метода лечения: 5-летняя скорректированная выживаемость пациентов 1-й группы составила 84,6 + 9,8 %, 2-й — 71,0 + 11,2 %.</p><p><bold>Заключение</bold>. Применение метода СЛТ у пациентов, страдающих РПЖ с высоким риском прогрессирования, характеризуется удовлетворительными отдаленными результатами лечения. В подгруппе пациентов с умеренно и низкодифференцированным РПЖ СЛТ была ассоциирована со статистически значимо лучшими отдаленными результатами по сравнению с ДЛТ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>prostate cancer</kwd><kwd>combined radiation therapy</kwd><kwd>external beam radiotherapy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак предстательной железы</kwd><kwd>сочетанная лучевая терапия</kwd><kwd>дистанционная лучевая терапия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Okeanov A.E., Moiseev P.I., Levin L.F.
