Due to its high sensitivity and specifi city and the ability to be used in solving diff erent clinical problems such as diagnosing and then monitoring of tumor burden, evaluating the probability of disease relapse and also correction of therapy used in case of detecting tumor’s resistance to it, this method is one of the most perspective to be implemented into public healthcare. Nevertheless, its high cost, a little quantity of clinical trials and necessity of standardization cannot aff ord this method to be used in clinic now. </p></abstract><trans-abstract xml:lang="ru"><p>В стать е представлен обзор одного из наиболее интенсивно изучаемых в настоящее время методов диагностики онкологических заболеваний – генетического анализа циркулирующей опухолевой ДНК. Благодаря высокой чувствительности и специфичности, а также возможности применения при решении различных клинических задач – диагностике, контроле течения, оценке вероятности рецидива онкологических заболеваний, а также коррекции проводимого лечения при обнаружении резистентности опухоли к химиотерапевтическим препаратам – данный метод представляется наиболее перспективным с точки зрения внедрения в общественное здравоохранение. Тем не менее, высокая стоимость исследования, малое количество проведенных клинических испытаний и необходимость стандартизации на данный момент не могут позволить ему занять место в клинике. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>циркулирующая опухолевая ДНК</kwd><kwd>онкология</kwd><kwd>диагностика рака</kwd><kwd>онкологические биомаркеры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>circulating tumor DNA</kwd><kwd>oncology</kwd><kwd>cancer diagnostics</kwd><kwd>cancer biomarkers</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">Stewart B.
