We have conducted a retrospective analysis of the data from a prospectively collected database. We included patients with stages сT2–3N0M0 and сT2–3N1–2M0 resectable rectal cancer. Polyradiomodification regimens included a course of radiotherapy (5 × 5 Gy) with the following radiomodifiers: rectal administration of a biopolymer composition containing metronidazole (MZ)  at a dose of 10 g/m<sup>2</sup> (twice), intracavitary local microwave hyperthermia (three times on days 3–5) and oral capecitabine (Cap).</p><p><bold>Results.</bold> The study included 241 participants. Toxic reactions were observed in less than 33.2 % of patients receiving polyradiomodification as a part of combination therapy. The most common adverse events were gastrointestinal toxicity and neurotoxicity, diagnosed in 28.6 % and 17.4 % of cases respectively. The frequency of toxic reactions was significantly higher in patients receiving Cap14 + MZ regimen than in those receiving Cap5 + MZ regimen (p = 0.0038). However, the inclusion of microwave hyperthermia in both Cap5 and Cap14 therapeutic regimens had no impact on the frequency of toxic reactions (44.2 and 31.5 % respectively, p = 0.146). The proportion of patients with grade III gastrointestinal toxicity did not significantly vary across the groups (p = 0.16).</p><p><bold>Conclusion.</bold> The course of polyradiomodification included into the combination therapy for rectal cancer has an acceptable toxicity profile and can be used to improve long-term outcomes of combination treatment for rectal cancer.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования</bold> – изучить профиль токсических проявлений программы полирадиомодификации в схемах комбинированного лечения больных раком прямой кишки.</p><p><bold>Материалы и методы</bold>. Исследование основано на ретроспективном анализе проспективно собранной базы данных. Включались пациенты с резектабельным раком прямой кишки и стадиями заболевания сT2–3N0M0 и сT2–3N1–2M0. Программа полирадиомодификации состояла из курса лучевой терапии 5 × 5 Гр с использованием следующих радиомодификаторов: 2-кратное внутриректальное введение биополимерной композиции с метронидазолом (МЗ) (10 г/м<sup>2</sup>), 3-кратная внутриполостная локальная сверхвысокочастотная гипертермия (дни 3–5) и пероральный прием капецитабина (Кап).</p><p><bold>Результаты.</bold> В исследование включен 241 пациент. Установлено, что в процессе проведения комбинированного лечения в сочетании с программой полирадиомодификации токсические проявления диагностированы не более чем у 33,2 % пациентов. Наиболее часто отмечались гастроинтестинальная токсичность (28,6 %) и нейротоксичность (17,4 %); при использовании Кап14 + МЗ в схеме полирадиомодификации токсические проявления диагностировались достоверно (p = 0,0038) чаще, чем при использовании схемы Кап5 + МЗ. В то же время добавление к схемам лечения Кап14 и Кап5 локальной сверхвысокочастотной гипертермии не приводило к достоверному увеличению (p = 0,146) частоты токсических проявлений (44,2 и 31,5 % соответственно). Показатели гастроинтестинальной токсичности III степени во всех группах больных достоверно не различались (p = 0,16).</p><p><bold>Выводы</bold>. Программа полирадиомодификации, включенная в схему комбинированного лечения больных раком прямой кишки, обладает приемлемым профилем токсичности и может быть применена для улучшения отдаленных результатов комбинированного метода лечения больных раком прямой кишки.</p></trans-abstract><kwd-group xml:lang="en"><kwd>rectal cancer</kwd><kwd>combination therapy</kwd><kwd>polyradiomodification</kwd><kwd>toxicity</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак прямой кишки</kwd><kwd>комбинированное лечение</kwd><kwd>полирадиомодификация</kwd><kwd>токсичность</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">Heald R.J.
