Улучшить результаты лечения больных, страдающих колоректальным раком (КРР) с олигометастатическим поражением, за счет определения наиболее эффективной комбинации методов лечения.</p></sec><sec><title>Пациенты и методы</title><p>Пациенты и методы. Проведен анализ результатов лечения 71 пациента с олигометастазами КРР. Все больные были разделены на 2 группы в зависимости от методов лечения. В первую группу включены 35 больных, которым на первом этапе комплексного лечения проводилось одномоментное удаление первичной опухоли и метастатических очагов, с последующим проведением химиотерапии. Во вторую группу включены клинические данные о 36 больных, которым на первом этапе комплексного лечения проводилось удаление первичного очага с последующим проведением лекарственной противоопухолевой терапии.</p></sec><sec><title>Результаты</title><p>Результаты. В группе удаления первичной опухоли ответ получен в 3 (8,3 %) случаях, стабилизация достигнута в 14 (38,9 %) случаях, в 19 (52,8 %) случаях выявлено прогрессирование опухолевого процесса. Медиана безрецидивной выживаемости составила 9,2 ± 3,2 мес. Годичная, двух- и трехлетняя выживаемость в группе одномоментного удаления первичной опухоли и олигометастазов и в группе удаления первичной опухоли составила 97,1, 88,6, 77,1 и 100, 80,5, 72,2 % соответственно. Общая выживаемость в группе одномоментного удаления первичной опухоли и олигометастазов составила 63 ± 3,9 мес., в группе удаления первичной опухоли – 58 ± 3,8 мес.</p></sec><sec><title>Заключение</title><p>Заключение. В представленном клиническом исследовании проводилась сравнительная оценка эффективности проводимого лечения больных КРР с олигометастазами в зависимости от варианта комплексного подхода. Полученные результаты оказались разнонаправленными – ответ на лечение и прогрессирование получены в 54,3 и 45,7 % случаях в группе одномоментного удаления первичной опухоли и олигометастазов против 47,2 и 52,8 % случаев в группе удаления первичной опухоли без олигометастазов соответственно. Медиана безрецидивной выживаемости оказалась короче в группе удаления первичной опухоли без метастазов. Удаление олигометастазов увеличивает общую выживаемость, но результаты не достигают статистической значимости.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose of the study</title><p>Purpose of the study. To improve the treatment results of patients suffering from CRC with oligometastatic lesion by determining the most effective combination of treatment methods.</p></sec><sec><title>Patients and methods</title><p>Patients and methods. The results of treatment of 71 patients with oligometastases of colorectal cancer were analyzed. All patients were divided into 2 groups depending on the treatment methods. The first group included 35 patients who underwent simultaneous removal of the primary tumor and metastatic foci at the first stage of complex treatment. The second group includes clinical data on 36 patients who underwent primary lesion removal at the first stage of complex treatment followed by drug antitumor therapy.</p></sec><sec><title>Results</title><p>Results. In the primary tumor removal group, the response was received in 3 (8.3 %) cases, stabilization was achieved in 14 (38.9 %) cases, and progression of the tumor process was detected in 19 (52.8 %) cases. The median disease-free survival was 9.2 ± 3.2 months. One-year, two- and three-year survival rates in the group of simultaneous removal of the primary tumor and oligometastases and in the group of primary tumor removal were 97.1 %, 88.6 %, 77.1 % and 100 %, 80.5 %, 72.2 %, respectively. The overall survival rate in the group of simultaneous removal of the primary tumor and oligometastases was 63 ± 3.9 months, in the group of primary tumor removal – 58 ± 3.8 months.</p></sec><sec><title>Conclusion</title><p>Conclusion. In the presented clinical study, a comparative assessment of the effectiveness of the treatment of patients with colorectal cancer with oligometastases was carried out, depending on the option of an integrated approach. The results obtained turned out to be multidirectional – the response to treatment and progression were obtained in 54.3 % and 45.7 % of cases in the group of simultaneous removal of the primary tumor and oligometastases versus 47.2 % and 52.8 % of cases in the group of removal of the primary tumor without oligometastases, respectively. The median recurrence-free survival was shorter in the group of primary tumor removal without metastases. Complete removal of the primary tumor and oligometastases can significantly increase the overall survival rates of patients.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>колоректальный рак</kwd><kwd>олигометастазы</kwd><kwd>химиотерапия</kwd><kwd>метастазы в легком</kwd><kwd>метастазы в печени</kwd></kwd-group><kwd-group xml:lang="en"><kwd>colorectal cancer</kwd><kwd>oligometastases</kwd><kwd>chemotherapy</kwd><kwd>lung metastases</kwd><kwd>liver metastases</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы считают своим долгом выразить слова благодарности к.м.н., заведующей отделением противоопухолевой лекарственной терапии ЧУЗ ЦКБ «РЖД-Медицина» Селезневой Ирине Ивановне за ценные замечания в процессе осуществления научной и практической части работы и всестороннюю поддержку</funding-statement><funding-statement xml:lang="en">The authors consider it their duty to express gratitude to Irina Ivanovna Selezneva, PhD., Head of the Department of antitumor Drug therapy at the Central Research Hospital «RZD-Medicine» for valuable comments in the process of carrying out the scientific and practical part of the work and comprehensive support</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Sung H, Ferlay J, Siegel RL, Laversanne M, Soerjomataram I, Jemal A, et al.
