The majority of patients are diagnosed at stages II–IV, which indicates the need for markers that can predict disease progression, especially after surgical treatment. Recently, there has been a growing interest in exploring circulating tumor DNA as a marker of residual tumor in colon cancer. In 2018, the N.N. Blokhin National Medical Research Center of Oncology together with the Institute of Chemical Biology and Fundamental Medicine under the coordination of the Center for Strategic Planning and Management of Biomedical Health Risks initiated a research project entitled “Development of an assay for the diagnosis of various malignant tumors and treatment efficacy monitoring based on the analysis of circulating tumor DNA from patient blood”. This article provides a theoretical background for the project and a report on its progress made so far.</p></abstract><trans-abstract xml:lang="ru"><p>На рак толстой кишки приходится 3-е место по заболеваемости злокачественными новообразованиями в мире и 4-е место по смертности от них. При этом в большинстве случаях опухоль диагностируется на II–IV стадиях заболевания, что говорит о необходимости изучения маркеров прогрессирования, особенно после радикального лечения. В связи с этим в последние годы появился интерес к изучению в качестве маркера резидуальной опухоли при раке толстой кишки циркулирующей в крови опухолевой ДНК. В 2018 г. ФГБУ «Национальный медицинский исследовательский центр онкологии им. Н. Н. Блохина» совместно с ФГБУН «Институт химической биологии и фундаментальной медицины Сибирского отделения РАН» при координации ФГБУ «Центр стратегического планирования и управления медико-биологическими рисками здоровью» в рамках экспериментального государственного задания Минздрава России инициировали научно-исследовательскую работу «Разработка тест-системы для диагностики и мониторинга эффективности проводимого лечения злокачественных новообразований различной локализации на основе анализа циркулирующей в крови пациентов опухолевой ДНК». В настоящей статье описываются теоретические предпосылки к инициации данного исследования и сообщается, на каком этапе находится выполнение работы.</p></trans-abstract><kwd-group xml:lang="en"><kwd>colon cancer</kwd><kwd>circulating tumor DNA</kwd><kwd>liquid biopsy</kwd><kwd>prognosis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак толстой кишки</kwd><kwd>циркулирующая в крови опухолевая ДНК</kwd><kwd>жидкостная биопсия</kwd><kwd>прогноз</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Malignant tumors in Russia in 2016 (morbidity and mortality).
