Возможными причинами могут являться длительно персистирующий воспалительный процесс в кишечнике, генетические мутации, а также технические сложности при диагностике подобных состояний. Целью проведенной работы являлась оценка факторов риска развития рака кишечника на фоне болезни Крона, а также оценка особенностей клинического течения сочетанных патологий.</p></sec><sec><title>ПАЦИЕНТЫ И МЕТОДЫ</title><p>ПАЦИЕНТЫ И МЕТОДЫ: в рамках работы ретроспективно были проанализированы 1478 историй болезни пациентов с болезнью Крона, наблюдавшихся в 2020–2024 гг. Среди них было выявлено 11 пациентов с диагностированным раком кишечника.</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ: при анализе историй болезни удалось установить: колоректальный рак на фоне болезни Крона развивался в основном у пациентов с длительным анамнезом заболевания, у которых воспалительные изменения в кишечнике были выявлены в молодом возрасте, а также отмечались осложнения заболевания (свищи, стриктуры, перианальные проявления). По поводу болезни Крона пациенты получали терапию различными генно-инженерными биологическими препаратами. При выявлении колоректального рака опухоль локализовалась в толстой или прямой кишке, чаще имела распространенный характер, имела гистологическое строение аденокарциномы. После лечения (неоадъювантная химиолучевая терапия, адъювантная химиотерапия, хирургическое лечение) пациенты наблюдались в течение 0–16 месяцев, за время наблюдения рецидивов болезни Крона и колоректального рака не определялось.</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ: требуются дальнейшие исследовательские работы, направленные на оценку факторов риска развития рака кишечника на фоне болезни Крона, особенностей течения болезни Крона после выявленного рака кишечника и разработки подходов к диагностике, лечению и профилактики подобных состояний.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>AIM</title><p>AIM: to assess risk factors for bowel cancer associated with Crohn's disease, as well as to assess the clinical features of the combined pathologies.</p></sec><sec><title>PATIENTS AND METHODS</title><p>PATIENTS AND METHODS: retrospective study included 1,478 medical records of patients with Crohn's disease in 2020–2024. Eleven patients with bowel cancer were identified.</p></sec><sec><title>RESULTS</title><p>RESULTS: history analysis revealed that colorectal cancer developed mainly in patients with a long history of the CD, in whom inflammatory changes in the intestine were detected at a young age, and complications of the disease were noted as well (fistulas, strictures, perianal manifestations). For CD, patients received therapy with various genetically engineered biological agents. When colorectal cancer was detected, the tumor was localized in the colon or rectum, and had the histological structure of adenocarcinoma. After treatment (neoadjuvant chemoradiation therapy, adjuvant chemotherapy, surgery), patients were followed up for 0–16 months, during this period, relapses of Crohn's disease and colorectal cancer were not detected.</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION: further studies are needed to assess the risk factors for the development of bowel cancer in the presence of Crohn's disease, the characteristics of the course of Crohn's disease after diagnosed bowel cancer, and the development of approaches to the diagnosis, treatment, and prevention of such conditions.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>болезнь Крона</kwd><kwd>колоректальный рак</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Crohn's disease</kwd><kwd>colorectal cancer</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">Shah SC, Itzkowitz SH.
