Проведено ретроспективное исследование историй болезни 582 больных колоректальным раком (КРР), которые проходили лечение с 1.01.19 по 1.12.24 в хирургическом отделении абдоминальной онкологии ГУЗ «Областной клинический онкологический диспансер» г. Ульяновска. Согласно критериям включения и исключения, в исследование вошло 572 пациента. Оценка осложнений проводилась по классификации Clavien–Dindo. Пациенты были разделены на две группы – моложе и старше 75 лет. Результаты. При однофакторном анализе не выявлено различий между группами по основным клинико-демографическим параметрам, а также сопутствующей патологии. Однако индекс коморбидности Charlson был выше у пациентов старше 75 лет (p&lt;0,001). У пациентов старше 75 лет чаще выполнялась правосторонняя гемиколонэктомия – в 58 (56,9 %) случаях, далее следует резекция сигмовидной кишки – 38 (37,3 %). Частота несостоятельности анастомоза была выше у пациентов старше 75 лет, но значимых различий между группами не выявлено (p=0,065). Анализ частоты послеоперационных осложнений, стратифицированных по Clavien–Dindo, показал отсутствие значимых различий между группами (p=0,247). При проведении многоуровневой логистической регрессии выявлены следующие предикторы несостоятельности анастомоза: уровень альбумина до операции, на 1-е и 5-е сут после операции, а также нейтрофил-лимфоцитарный индекс (НЛИ) на 1-е и 5-е сутки после операции. Заключение. Возраст пациента не может рассматриваться как независимый фактор развития несостоятельности анастомоза после резекции толстой кишки, выполненной по поводу КРР. Значимыми предикторами развития несостоятельности являются показатели НЛИ на 1-е и 5-е сут после операции, а также уровень альбумина до операции и на 1-е и 5-е сут после операции.</p></abstract><trans-abstract xml:lang="en"><p>Objective: to evaluate surgical treatment outcomes in colorectal cancer patients aged younger and older than 75 years. Materials and methods. A retrospective analysis of medical records was conducted for 582 colorectal cancer patients treated between January 1, 2019, and December 1, 2024, at the Department of Abdominal Oncology Surgery, Regional Clinical Oncology Hospital, Ulyanovsk, Russia. Based on inclusion and exclusion criteria, 572 patients were included in the study. Postoperative complications were assessed using the Clavien–Dindo classifcation, and tumors were staged according to the TNM system. The patients were categorized into two age groups: a younger group consisting of patients younger than 75 years, and an older group including those aged 75 years or older. Results. Univariate analysis revealed no statistically signifcant differences in baseline clinical and demographic characteristics or comorbidities between the patient groups. However, the Charlson comorbidity index was signifcantly higher in patients aged 75 years and older (p &lt; 0.001). Compared to the younger group patients, the older group patients more frequently underwent right-sided hemicolectomy (58, 56.9%), followed by sigmoid colon resection (38, 37.3%). The incidence of anastomotic leakage was higher in older patients than in younger patients, but this difference did not reach statistical signifcance (p = 0.065). No signifcant differences in postoperative complications stratifed by the Clavien–Dindo classifcation were found between the patient groups (p = 0.247). Multilevel logistic regression identifed the following predictors of anastomotic leakage: preoperative albumin level, albumin level on postoperative days 1 and 5, as well as the neutrophil-to-lymphocyte ratio on postoperative days 1 and 5. Conclusion. Patient age is not considered an independent factor for anastomotic leakage after colorectal cancer resection. Signifcant predictors of anastomotic leakage include NLR on postoperative days 1 and 5, as well as preoperative albumin levels and albumin levels on postoperative days 1 and 5.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>колоректальный рак</kwd><kwd>оперативное лечение</kwd><kwd>возраст больных</kwd><kwd>несостоятельность толстокишечного анастомоза</kwd></kwd-group><kwd-group xml:lang="en"><kwd>colorectal cancer</kwd><kwd>surgery</kwd><kwd>patient age</kwd><kwd>colorectal anastomotic leakage</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">Bray F., Laversanne M., Sung H., Ferlay J., Siegel R.L., Soerjomataram I., Jemal A.
