NACT-related complications were assessed using CTCAE v.5.0, treatment response was evaluated per the RECIST 1.1 criteria, and the impact of NACT on postoperative complications and likelihood of adjuvant chemotherapy (ACT) completion were analyzed.</p> <p><bold>Results.</bold> The surgery-only (control) group included 108 patients, while the NACT group included 49 patients. Grade III NACT-related complications developed in 2 (4.4 %) patients. Partial response (PR) to NACT was observed in 5 (10.2 %) patients, with stable disease was achieved in 40 (81.6 %) patients. R0 resection was achieved in 91 (84.3 %) patients in the surgery-only group and 47 (95.9 %) in the NACT group (<italic>p</italic> = 0.113). NACT did not affect the risk of severe postoperative complications (hazard ratio 0.482; 95 % confidence interval 0.183–1.268; <italic>p</italic> = 0.139). Patients receiving NACT completed ACT more frequently compared to control group: 76 (70.4 %) <italic>versus</italic> 43 (87.8 %), respectively (<italic>p</italic> = 0.026).</p> <p><bold>Conclusion.</bold> NACT demonstrated high safety but low PR rates and no impact on R0 resection achievement probability.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Неоадъювантная химиотерапия (НАХТ) не входит в стандарты лечения больных внутрипеченочной холангиокарциномой (ВПХК).</p> <p><bold>Цель исследования</bold> – сравнительная оценка непосредственных результатов лечения больных ВПХК в зависимости от проведения НАХТ.</p> <p><bold>Материалы и методы. </bold>В ретроспективный анализ включены пациенты, которым выполнялось хирургическое вмешательство по поводу ВПХК в период с 2010 по 2024 г. Оценивали осложнения НАХТ (по шкале CTCAE v.5.0), частоту ответа на предоперационное лечение (по шкале RECIST 1.1), влияние НАХТ на риск послеоперационных осложнений и вероятность проведения адъювантной химиотерапии.</p> <p><bold>Результаты.</bold> В группу хирургического лечения (контрольная группа) вошло 108 пациентов, в группу НАХТ – 49. Осложнения НАХТ III степени отмечены у 2 (4,4 %) пациентов. Частичный ответ на НАХТ зарегистрирован у 5 (10,2 %) пациентов, стабилизация – у 40 (81,6 %). Резекция в объеме R0 выполнена у 91 (84,3 %) больного в контрольной группе и 47 (95,9 %) в группе НАХТ (<italic>р</italic> = 0,113). Проведение НАХТ не влияло на риск развития тяжелых послеоперационных осложнений (отношение рисков 0,482; 95 % доверительный интервал 0,183–1,268; <italic>р</italic> = 0,139). Пациенты, получавшие НАХТ, чаще проходили адъювантную химиотерапию: 76 (70,4 %) случаев против 43 (87,8 %) случаев в контрольной группе (<italic>р</italic> = 0,026).</p> <p><bold>Заключение.</bold> НАХТ продемонстрировала высокую безопасность, однако низкую частоту достижения частичного ответа на лечение и отсутствие влияния на вероятность достижения R0-резекции.</p></trans-abstract><kwd-group xml:lang="en"><kwd>cholangiocarcinoma</kwd><kwd>resectable biliary tract cancer</kwd><kwd>preoperative therapy</kwd><kwd>surgical treatment</kwd><kwd>multimodal therapy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>холангиокарцинома</kwd><kwd>резектабельный билиарный рак</kwd><kwd>предоперационная терапия</kwd><kwd>хирургическое лечение</kwd><kwd>комбинированное лечение</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Yang Z., Jiang X.
