Важным моментом в профилактике этой патологии является скрининг и неинвазивная ранняя диагностика, своевременное определение прогноза, стадии и подходов к терапии. Представленный обзор посвящен методам диагностики колоректального рака. Программы национального скрининга основаны на доказательствах эффективности методов и внедрены в практику здравоохранения. В обзоре литературы приведены современные данные применения сывороточных биомаркеров в качестве скрининга, диагностики, прогноза. Отражены как диагностическая ценность классических сывороточных маркеров (РЭА, СА 19-9, СА 72-4), так и новых (циклооксигеназы, к53, Fas, TIMP-1, ММР-9, IL8, IL6, TGFB1, TIMP2 и IGF2). Изучены вопросы сложности подбора сывороточных маркеров и ограничения их применения.</p></abstract><trans-abstract xml:lang="en"><p>The incidence of colorectal cancers is constantly growing and reflects global trends. Prophylactic of pathology includes screening and non-invasive episodes of diagnosis, prognosis of neoplastic disease, stages and pathologies. A review has been provided of the diagnosis of colorectal cancer. The programs of national screening are based on techniques and evidence-based healthcare practices. The review shows recent information on serum biomarkers in screening, diagnosis, prognosis, diagnostic value of classical serum markers (CEA, CA 19-9, CA 72-4), and novel they (cyclooxygenase, k53, Fas, TIMP-1, MDR-9, IL8, IL6, TGFB1, TIMP2 and IGF2). The review told about the problems of the selection of serum markers and the limitations of their use.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>колоректальный рак</kwd><kwd>биомаркеры</kwd><kwd>онкомаркеры</kwd><kwd>РЭА</kwd><kwd>скрининг</kwd><kwd>колоректальды рак</kwd><kwd>биомаркер</kwd><kwd>ісік маркері</kwd><kwd>скрининг</kwd></kwd-group><kwd-group xml:lang="en"><kwd>colorectal cancer</kwd><kwd>biomarkers</kwd><kwd>tumor markers</kwd><kwd>CEA</kwd><kwd>screening</kwd><kwd>CEA</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">Головков Д.
