The patients with low rectal cancer (0—6 cm from anocutaneous line) were randomized into 3 groups: in the 1st control group surgery was performed in 0—3 days after completion of short-course radiotherapy (5 х 5 Gy). Patients in the 2nd control group received identical radiotherapy but the interval before surgery was extended to 42 ± 3 days. Patients in the study group received treatment identical to 2nd control group with 2 additional courses of monochemotherapy with capecitabine, starting on the first day of radiotherapy. The primary endpoint was the number of SPO. Complete pathomorphologic response rate, overall survival, tumor-specific survival and event-free 5-year survival were also assessed as secondary endpoints.</p><p><bold>Results.</bold> Data on 129 patients was analyzed: 46 in the 1st control group, 43 in the 2nd control group, 40 in the study group. The proportion of SPO was 41,3 ± 7,3 % in the 1st group, 69,7 ± 7,0 % and 77,5 ± 6,6 % in the 2nd group and study group, respectively. Complete histological response was achieved in 15 % of patients in study group, comparing to 14,3 % of patients in the 2nd group. Overall 5-year survival in this study was estimated to be 77,8 ± 4,5%, tumor-specific survival — 89,7 ± 3,7 %, event-free survival — 90,1 ± 2,9 %, with no significant differences between groups.</p><p><bold>Conclusion.</bold> Short-course radiotherapy (5 х 5 Gy) with 6-week interval before surgery resulted in increase of SPO rate with no affect on oncologic outcome.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования</bold> — оценить влияние вида предоперационного лечения на частоту выполнения сфинктеросохраняющих операций (ССО) у больных низколокализованным раком прямой кишки.</p><p><bold>Материалы и методы</bold>. Пациенты с низколокализованным (0—6 см от анокутанной линии) раком прямой кишки были рандомизированы в 3 группы: в 1-й контрольной операция выполнялась через 0—3 сут после окончания «короткой» лучевой терапии 5 х 5 Гр. Во 2-й контрольной группе после идентичной лучевой терапии интервал до операции составил 42 ± 3 дня. В основной группе в дополнение к схеме 2-й группы с 1-го дня лучевой терапии проводилось 2 курса монохимиотерапии капецитабином. Основным оцениваемым параметром была частота выполнения ССО. Оценивались также частота полного морфологического ответа, общая, скорректированная и бессобытийная 5-летняя выживаемость.</p><p><bold>Результаты.</bold> В исследование было включено 129 пациентов: 46 в 1-ю контрольную группу, 43 во 2-ю контрольную группу, 40 в основную группу. Частота выполнения ССО в 1-й группе составила 41,3 ± 7,3 %, во 2-й и основной — 69,7±7,0 и 77,5 ± 6,6 % соответственно. Полный гистологический ответ отмечен у 14,3 % пациентов во 2-й группе и у 15 % — в основной. Пятилетняя выживаемость для всех пациентов в исследовании составила 77,8 ± 4,5 %, скорректированная — 89,7 ± 3,7 %, бессобытийная — 90,1 ± 2,9 %, без достоверных различий в группах.</p><p><bold>Выводы. </bold>Использование после проведения «короткой» лучевой терапии 5 х 5Гр 6-недельного интервала перед операцией позволило увеличить количество ССО без ухудшения онкологических результатов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>low rectal cancer</kwd><kwd>neoadjuvant radiotherapy</kwd><kwd>surgical</kwd><kwd>combined and complex treatment</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>низколокализованный рак прямой кишки</kwd><kwd>неоадъювантная лучевая терапия</kwd><kwd>хирургическое</kwd><kwd>комбинированнное и комплексное лечение</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., Evmenenko A.A.
