In 97 patients with first diagnosed PTC, surgical removal of the cervical lymph node-bearing fat at levels II–IV was performed. All patients underwent preoperative neck ultrasound. The results were verified by histology.<bold>Results</bold>. Cervical levels II–IV lymph node metastases were revealed in 82 (84,5 %) cases by sonography and in 86 (88,6 %) cases by histology. Ultrasound showed a sensitivity of 93 %, specificity of 81 %, accuracy of 91 %, positive predictive value of 97 % and negative predictive value of 60 %. Of 1620 removed lymph nodes, 443 (27,3 %) showed metastases confirmed by histology. Sonography revealed 422 (26,0 %) metastatic lymph nodes. Metastasis from intra-thyroid tumors was noted in 94,1 % and from extra-thyroid tumors in 87,5 % of patients. Metastasis from solitary tumors occurred in 86,5 % and from multicentric tumors in 92,1 % of cases. Multiple metastases made up 89,5 % and solitary metastases – 10,5 %.<bold>Conclusion</bold>. Sonography is a highly informative diagnostic imaging method in detecting metastasis from PTC to levels II–IV cervical lymph nodes and can be used for basic assessment of thyroid abnormalities.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования</bold> – оценить возможности ультразвукового исследования (УЗИ) в диагностике метастазов папиллярного рака щитовидной железы (ПРЩЖ) в лимфатических узлах (ЛУ) шеи II–IV уровней.<bold>Материалы и методы</bold>. У 97 пациентов с впервые установленным диагнозом ПРЩЖ выполнено хирургическое удаление подкожной жировой клетчатки шеи II–IV уровней. В дооперационный период у всех пациентов проведено УЗИ шеи. Результаты верифицированы гистологическим методом.<bold>Результаты</bold>. Метастазы в ЛУ шеи II–IV уровней выявлены по данным УЗИ у 82 (84,5 %) пациентов, по гистологическим данным – у 86 (88,6 %). Чувствительность УЗИ составила 93 %, специфичность – 81 %, точность – 91 %, прогностическая ценность положительного результата – 97 %, отрицательного результата – 60 %. В 443 (27,3 %) из 1620 удаленных ЛУ метастазы были подтверждены гистологическим методом. При этом по данным УЗИ они имелись в 422 (26,0 %) ЛУ. При внутриорганных опухолях метастазы наблюдались в 94,1 % случаев, при внеорганных – в 87,5 %. Солитарные опухоли давали метастазы в 86,5 % случаев, мультицентрические – в 92,1 %. Множественные метастазы выявлены в 89,5 %, одиночные – в 10,5 %.<bold>Заключение</bold>. УЗИ оказалось высокоинформативным методом выявления метастазов ПРЩЖ в ЛУ шеи II–IV уровней шеи и может стать базовым методом достижения данной диагностической цели.</p></trans-abstract><kwd-group xml:lang="en"><kwd>papillary thyroid cancer</kwd><kwd>cervical levels II–IV lymph node metastases</kwd><kwd>ultrasound</kwd><kwd>histological verification</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>папиллярный рак щитовидной железы</kwd><kwd>метастазы II, III, IV уровней шеи</kwd><kwd>ультразвуковое исследование</kwd><kwd>гистологическая верификация</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">Paches A.I.
