N. Blokhin National Medical Research Center of Oncology between 2017 and 2019. Patients with asymptomatic primary tumor located in rectum and rectosigmoid junction with synchronous resectable / borderline resectable metastasis in liver. 22 patients were planned to undergo the liver-first approach. Post-operative morbidity and mortality (Clavien–Dindo) as well as tumor regression grading (Dworak) were evaluated.</p><p><bold>Results.</bold> Of the 17 patients planned to undergo the liver-first strategy, the approach was completed in 15 (88,2 %) patients. The main reason for treatment failure was disease progression. Post-operative morbidity and mortality were 13,3 % and 0 %, respectively.</p><p><bold>Conclusions.</bold> Liver-first approach is justified in two cases: during waiting period after last day of chemoradiotherapy in patients with locally advanced (invasion depth T4a, positive circumferential resection margin, N+ status) mid-to-low rectal cancer and in patients with multiple borderline resectable bilobar liver damage.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования</bold> – оценка непосредственных результатов лечения больных метастатическим раком прямой кишки, в отношении которых была использована тактика «сначала печень».</p><p><bold>Материалы и методы.</bold> Проведено ретроспективное исследование проспективно набранной группы больных, пролеченных в ФГБУ «Национальный медицинский исследовательский центр онкологии им. Н. Н. Блохина» Минздрава России в период с 2017 по 2019 г. В исследуемую группу вошли пациенты с асимптомной первичной опухолью прямой кишки и ректосигмоидного соединения с синхронными резектабельными / погранично резектабельными метастазами в печени. Основными оцениваемыми параметрами были послеоперационные осложнения и патоморфоз опухоли. Послеоперационные осложнения оценивали по классификации Clavien– Dindo, степень лечебного патоморфоза – по Dworak.</p><p><bold>Результаты.</bold> Из 17 пациентов только 15 (88,2 %) прошли лечение в соответствии с предложенной тактикой. Главной причиной этого стало прогрессирование основного заболевания. Доля послеоперационных осложнений и летальных исходов составила 13,3 и 0 % соответственно.</p><p><bold>Выводы.</bold> Тактика «сначала печень» безопасна и может применяться лишь в 2 случаях: в период ожидания реализации эффекта химиолучевой терапии у пациентов с первичной опухолью средне- и нижнеампулярного отдела прямой кишки с негативными факторами прогноза по локальному прогрессированию (глубина инвазии T4a, положительная циркулярная граница резекции, N+-статус) и у пациентов с погранично резектабельным множественным билобарным поражением печени.</p></trans-abstract><kwd-group xml:lang="en"><kwd>liver-first approach</kwd><kwd>synchronous metastases in liver</kwd><kwd>liver resection</kwd><kwd>resection of colon</kwd><kwd>rectum</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>тактика «сначала печень»</kwd><kwd>синхронные метастазы в печени</kwd><kwd>резекция печени</kwd><kwd>резекция прямой кишки</kwd><kwd>прямая кишка</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Manfredi S., Lepage C., Hatem C. et al.
