Синдром семейного аденоматозного полипоза является тяжелым онкоассоцированным заболеванием, которое, как правило, манифестирует в детском возрасте. Отсутствие лечение приводит к развитию колоректального рака в 100%. Цель. Представить актуальные данные об этиологии, патогенезе, диагностике и лечении пациентов с семейным аденоматозным полипозом. Основная часть. Семейный аденоматозный полипоз является генетически детерминированным заболеванием, которое развивается в следствие мутации в гене-супрессоре АРС. Подавляющее количество аденоматозный полипов формируется в толстой кишке. Аденома - неопластическое образование, которая может стать аденокарциномой. Однако в связи с тем, что при САП в просвете кишки могут быть несколько тысяч полипов, риск малигнизации приближается к 100%. Заключение. Радикальным лечением САП исключительно является тотальная колэктомия. Однако аденомы образуются и в тонкой кишке, в связи с чем пациентам требуется постоянное наблюдение и эндоскопическое лечение, так как рак двенадцатиперстной кишки является второй по распространенности причиной смерти у пациентов с САП.</p></abstract><trans-abstract xml:lang="en"><p>Relevance. Familial adenomatous polyposis syndrome is a severe6 cancer-associated disease that usually manifests itself in childhood. If left untreated, it leads to the development of colorectal cancer in 100%. The purpose of this study is to provide up-to-date information on the etiology, pathogenesis, diagnosis, and treatment of patients with familial adenomatous polyposis. The main part. Familial adenomatous polyposis is a genetically determined disease that develops as a result of a mutation in the APC suppressor gene. The vast majority of adenomatous polyps are formed in the colon. An adenoma is a neoplastic growth that can become an adenocarcinoma. However, due to the fact that there can be several thousand polyps in the intestinal lumen in FAP, the risk of malignancy is close to 100%. Conclusion. The only radical treatment for SAP is total colectomy. However, adenomas can also form in the small intestine, requiring ongoing monitoring and endoscopic treatment, as duodenal cancer is the second leading cause of death in patients with SAP.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>семейный аденоматозный полипоз</kwd><kwd>MutYH - ассоциированный полипоз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>familial adenomatous polyposis</kwd><kwd>MutYH-associated polyposis</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">Half E, Bercovich D, Rozen P.
