In group 1, a clinically significant response (hematuria relief) was achieved in 63,0 % cases, in group 2 — in 62,5 %, in group 3 — in 91,7 % cases. The 10-year follow-up showed that in group 1, the median survival was 21,8 ± 3,3 months; in groups 2 and 3, the median survival was 27,0 ± 7,8 and 32,6 ± 9,8 months, respectively. In group 2, an increase in the rate of acute radiation reactions was noted, whereas in group 3, palliative EBRT did not produce higher rates and severity of acute radiation reactions and complications.</italic></p><p><bold><italic>Conclusion: </italic></bold><italic>Accelerated dynamic fractionation was found to shorten treatment times and to improve outcomes and quality of life for incurable patients with BC.</italic></p></abstract><trans-abstract xml:lang="ru"><p><bold><italic>Цель исследования </italic></bold><italic>— повышение эффективности паллиативной лучевой терапии у больных раком мочевого пузыря (РМП).</italic></p><p><bold><italic>Материалы и методы. </italic></bold><italic>В период с 1990 по 2010 г. 90 больным РМП с паллиативной целью проводили дистанционную лучевую терапию (ДЛТ) по 3 методикам: в 1-й группе (n = 37) — методика традиционного фракционирования, во 2-й (n = 22) — методика гипофракционирования, в 3-й (n = 31) — методика ускоренного динамического фракционирования.</italic></p><p><bold><italic>Результаты. </italic></bold><italic>Непосредственную эффективность ДЛТ оценивали по купированию местных симптомов заболевания. Клинически значимый эффект (купирование гематурии) в 1-й группе был достигнут в 63,0 % случаев, во 2-й группе — в 62,5 %, в 3-й группе — в 91,7 % случаев. Средняя продолжительность жизни за 10-летний период наблюдения у больных 1-й группы составила 21,8 ± 3,3 мес, у больных 2-й и 3-й групп 27,0 ± 7,8 и 32,6 ± 9,8 мес соответственно. Отмечено повышение частоты острых лучевых реакций у пациентов 2-й группы, в то время как в 3-й группе проведение паллиативной ДЛТ не сопровождалось увеличением частоты и тяжести значимых лучевых реакций и осложнений.</italic></p><p><bold><italic>Выводы. </italic></bold><italic>Методика ускоренного динамического фракционирования сокращает время лечения, улучшает его результаты и качество жизни инкурабельных больных РМП.</italic></p></trans-abstract><kwd-group xml:lang="en"><kwd>bladder cancer</kwd><kwd>palliative external beam radiation therapy</kwd><kwd>conventional fractionation</kwd><kwd>hypofractionation</kwd><kwd>accelerated dynamic fractionation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак мочевого пузыря</kwd><kwd>паллиативная лучевая терапия</kwd><kwd>традиционный режим фракционирования</kwd><kwd>гипофракцио-нирование</kwd><kwd>ускоренное динамическое фракционирование</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">1.
