However, the cytological material of the lymph nodes may not be adequate, and the detection of metastases faces a number of difficulties. In our recent study, we described a variant of the molecular classifier that allows the detection and typing of malignant thyroid tumors by analyzing several molecular markers in cytological preparations.</p><p><bold>The study objective</bold> was to assess the applicability of the developed method for the preoperative detection of metastases of papillary and medullary thyroid cancer in the lymph nodes of the neck lateral cellular tissue.</p><p><bold>Materials and methods.</bold> A total of 86 cytological samples were used, obtained from individual lymph nodes of 62 patients who had a diagnosis – thyroid cancer. Samples were analyzed by real-time polymerase chain reaction regarding the preselected set of molecular markers: the BRAF V600E mutation, the normalized concentration of HMGA2, FN1 and SERPINA1 mRNA, 5 miRNAs and the mitochondrial/nuclear DNA ratio. The decision tree-based classifier was used to discriminate between benign and malignant samples.</p><p><bold>Results.</bold> The previously described classifier, based on the analysis of the BRAF V600E mutation, the content of HMGA2 mRNA, 3 miRNAs and the mitochondrial/nuclear DNA ratio, revealed metastases of thyroid cancer with good specificity (98 %) but less sensitivity (83 %). Therefore, a new classifier was built, including three markers – HMGA2 and FN1 mRNA, and miRNA-375, which, with regard to the detection of metastases, showed good sensitivity – 93 % with a slight decrease in specificity (up to 96 %).</p><p><bold>Conclusion.</bold> Thus, we demonstrated the possibility of preoperative detection of thyroid cancer metastases in the lymph nodes of the neck lateral cellular tissue by analyzing several molecular markers in cytological material.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Основной метод дооперационной диагностики рака щитовидной железы (РЩЖ) и выявления его метастазов – цитологическое исследование препаратов, полученных при тонкоигольной аспирационной пункционной биопсии. Однако результаты такого исследования могут быть неопределенными, а обнаружение метастазов – затруднительным вследствие неопределенности цитологических признаков в ряде образцов. В своей недавней работе мы описали вариант молекулярного классификатора, позволяющего диагностировать и типировать злокачественные опухоли щитовидной железы путем выявления нескольких молекулярных маркеров в цитологических препаратах.</p><p><bold> Цель исследования</bold> – оценить возможности разработанного метода в дооперационном выявлении метастазов папиллярного и медуллярного РЩЖ в лимфатических узлах боковой клетчатки шеи.</p><p><bold>Материалы и методы.</bold> Исследовано 86 образцов, полученных при пункционной биопсии отдельных лимфатических узлов у 62 пациентов; во всех случаях по цитологическим данным диагностирован РЩЖ. Проведено исследование образцов методом полимеразной цепной реакции в реальном времени. Молекулярными маркерами РЩЖ считали наличие мутации V600E гена BRAF, нормализованную концентрацию мРНК HMGA2, FN1 и SERPINA1, 5 миРНК и соотношение митохондриальной и ядерной ДНК. Для деления образцов на доброкачественные и злокачественные были использованы классификаторы на основе дерева принятия решений.</p><p><bold>Результаты.</bold> Описанный ранее классификатор, основанный на анализе мутации V600E BRAF, содержания мРНК HMGA2, 3 микроРНК и соотношения митохондриальной и ядерной ДНК, позволил выявлять метастазы РЩЖ с хорошей специфичностью (98 %), но меньшей чувствительностью (83 %). Поэтому был создан новый классификатор, основанный на анализе 3 маркеров – HMGA2, FN1 и миРНК-375. Он характеризуется большей чувствительностью (93 %) в выявлении метастазов при лишь небольшом снижении специфичности (до 96 %).</p><p><bold>Заключение.</bold> Мы продемонстрировали возможность дооперационного выявления метастазов РЩЖ в лимфатических узлах боковой клетчатки шеи путем анализа нескольких молекулярных маркеров в цитологическом материале.</p></trans-abstract><kwd-group xml:lang="en"><kwd>thyroid cancer</kwd><kwd>metastases</kwd><kwd>lymph nodes</kwd><kwd>microRNA</kwd><kwd>molecular diagnostics</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак щитовидной железы</kwd><kwd>метастазы</kwd><kwd>лимфатические узлы</kwd><kwd>микроРНК</kwd><kwd>молекулярная диагностика</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Bongiovanni M., Spitale A., Faquin W.C. et al.
