Материал и методы. В исследование включено 30 пациентов с морфологически доказанным операбельным раком ободочной кишки cT3–4N0–2 стадии. Схема лечения включала в себя 8 курсов предоперационной химиотерапии по схеме FolFox-6 (оксалиплатин в дозе 85 мг/м2, внутривенно в виде 2-часовой инфузии в 1-й день, кальция фолинат в дозе 400 мг/м2, внутривенно в течение 2 ч с последующим болюсом 5-фторурацила в дозе 400 мг/м2, внутривенно струйно и внутривенной 46-часовой инфузией 5-фторурацила в дозе 2 400 мг/м2 (по 1 200 мг/м2/сут). Перерыв между курсами химиотерапии составлял 2 нед. После оценки эффективности терапии проводилось радикальное оперативное вмешательство с лимфодиссекцией D2. Интервал от окончания лекарственной терапии до проведения оперативного этапа комбинированного лечения составлял 6–8 нед. Результаты. Из 30 пациентов, включенных в исследование, лекарственную терапию в запланированном объёме получили 29 (96,7 %) больных, 1 (3,3 %) пациент получил 4 цикла НАХТ, лечение было прервано из-за полинейропатии III степени. Общий профиль токсичности неоадъювантной химиотерапии составил 73 %. Чаще всего наблюдались гематологические нежелательные явления – в 53,3 % и диспепсический синдром – в 26,7 % случаев. При предоперационной оценке полная регрессия зарегистрирована у 3 (10,3 %) больных, частичная регрессия – у 15 (51,7 %), стабилизация – у 9 (31,0 %), прогрессирование – у 2 (6,9 %) пациентов. Всем пациентам оперативное вмешательство проведено в радикальном объеме. В большинстве случаев (n=25, 83,3 %) выполнялись лапароскопические операции. Послеоперационные осложнения IIIа степени по шкале Clavien–Dindo возникли в 3 (10,0 %) случаях, у 1 (3,3%) пациента релапаротомия выполнялась в связи с несостоятельностью анастомоза, у 2 (6,7%) – по поводу кишечной непроходимости. При морфологическом исследовании операционного материала частота TRG 1 составила 6,9 %, TRG 2 – 17,2 %, TRG 3 – 17,2 %, TRG 4 – 48,2 %, TRG 5 – 10,3 % случаев. Феномен «downstaging» зафиксирован у 10 (34,5 %) больных. Заключение. Полученные результаты свидетельствуют о высокой непосредственной эффективности и удовлетворительной переносимости «тотальной» неоадъювантной химиотерапии по схеме FolFox-6 при комбинированном лечении рака ободочной кишки.</p></abstract><trans-abstract xml:lang="en"><p>The aim of this study was the development, clinical evaluation, assessment of tolerability, and immediate efficacy of combined treatment for patients with resectable colon cancer using total neoadjuvant chemotherapy (NACT) based on the FolFox-6 regimen. Material and methods. The study included 30 patients with morphologically verified operable colon cancer at stages cT3–4N0–2. The treatment protocol consisted of 8 courses of preoperative chemotherapy according to the FolFox-6 regimen: oxaliplatin 85 mg/m2 administered as a 2-hour intravenous infusion on day 1; calcium folinate 400 mg/m2 administered intravenously over 2 hours, followed by a bolus of 5-fluorouracil 400 mg/m2 intravenously, and a continuous 46-hour infusion of 5-fluorouracil 2400 mg/m2 (1200 mg/m2/day). The interval between chemotherapy courses was 2 weeks. After evaluating the effectiveness of the therapy, radical surgery with D2 lymphadenectomy was performed. The period from the end of chemotherapy to the surgical stage of combined treatment was 6–8 weeks. Results. Of the 30 patients enrolled, 29 (96.7 %) completed the planned chemotherapy regimen, while 1 patient (3.3 %) received only 4 cycles due to grade III polyneuropathy, resulting in treatment discontinuation. The overall toxicity profile of neoadjuvant chemotherapy was 73%. The most common adverse events were hematological toxicities (53.3 %) and dyspeptic syndrome (26.7 %). Preoperative assessment revealed complete regression in 3 patients (10.3 %), partial regression in 15 (51.7 %), disease stabilization in 9 (31.0 %), and progression in 2 (6.9 %). All patients underwent radical surgery (R0). In most cases (n=25, 83.3 %), laparoscopic procedures were performed. Postoperative complications of grade IIIa according to the Clavien–Dindo classification occurred in 3 cases (10.0 %): re-laparotomy was required for one patient (3.3 %) due to anastomotic leakage and for two patients (6.7 %) due to intestinal obstruction. Histopathological analysis of surgical specimens revealed the following tumor regression grades (TRG): TRG 1 – 6.9 %, TRG 2 – 17.2 %, TRG 3 – 17.2 %, TRG 4 – 48.2 %, and TRG 5 – 10.3 %. Tumor downstaging was observed in 10 patients (34.5 %). Conclusion. The obtained results indicate the high immediate efficacy and satisfactory tolerability of total neoadjuvant chemotherapy using the FolFox-6 regimen in the combined treatment of resectable colon cancer.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак ободочной кишки</kwd><kwd>«тотальная» неоадъювантная химиотерапия</kwd><kwd>комбинированное лечение</kwd><kwd>непосредственная эффективность</kwd><kwd>токсичность</kwd><kwd>лекарственный патоморфоз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>colon cancer</kwd><kwd>total neoadjuvant chemotherapy</kwd><kwd>combined treatment</kwd><kwd>immediate efficacy</kwd><kwd>toxicity</kwd><kwd>tumor regression</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ferlay J., Ervik M., Lam F., Laversanne M., Colombet M., Mery L., Piñeros M., Znaor A., Soerjomataram I., Bray F.
