В исследование включено 335 гистологически подтверждённых метастазов и 102 доброкачественных лимфатических узла (ЛУ). Статистическая обработка проведена в программе SPSS. Достоверность между группами оценена по критерию t с уровнем значимости р &lt; 0,05. Рассчитана информативность УЗ признаков и паттернов признаков, и вероятность наличия метастаза с использованием бинарной логистической регрессии.</p></sec><sec><title>Результаты</title><p>Результаты. Изучено 14 критериев метастазов. Установлено 33 признака – разновидностей критериев. При проведении статистического анализа установлено шесть наиболее информативных критериев: кальцинаты, контуры, форма, соотношение глубины к ширине в поперечной плоскости сканирования, состояние (дифференциация) коркового и мозгового слоев, эхоструктура. Для создания комплексов (паттернов) ультразвуковых признаков использовано сочетание данных признаков между собой и установлено пять паттернов. Первый паттерн, включающий соотношение глубины к ширине в поперечной плоскости сканирования и эхоструктуру, обладает чувствительностью (Se) 97 %, диагностической точностью (Ac) – 96,5 %, площадью под кривой (AUC) – 96 %, вероятность колеблется от 95 до 99 %. Se второго паттерна, включающего соотношение глубины к ширине в поперечной плоскости сканирования, эхоструктуру и форму, составила 97,2 %, Ac – 96,8 %, AUC – 97,3 %, вероятность – 95–100 %. Третий паттерн, включающий соотношение глубины к ширине в поперечной плоскости сканирования, природу, форму и контуры, и четвертый паттерн, включающий следующие критерии соотношение глубины к ширине в поперечной плоскости сканирования, эхоструктуру, форму, контуры и дифференциацию на корковый и мозговой слои, обладают Se 96,9 %, Ac – 97,1 %, AUC – 98,7 %, вероятностью – 88–100 %. Пятый паттерн, включающий соотношение глубины к ширине в поперечной плоскости сканирования, эхоструктуру, форму; контуры; состояние (дифференциация) коркового и мозгового слоев; кальцинаты, обладает Se – 99,6 %, Ac – 99,5 %, AUC – 99,9 %, вероятностью – 94–100 %.</p></sec><sec><title>Заключение</title><p>Заключение.

To assess ultrasound features and patterns of features for metastatic papillary thyroid cancer (PTC) in soft tissues of the neck.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study included 335 histologically confirmed metastases and 102 benign lymph nodes (LN). Statistical processing was carried out in the SPSS program. The reliability between the groups was assessed by criterion t with a significance level of p &lt; 0.05. The informative value of ultrasound signs and patterns of signs, and the probability of the presence of metastasis using binary logistic regression are calculated.</p></sec><sec><title>Results</title><p>Results. The 14 criteria for metastasis have been studied. There are 33 signs, i.e. types of criteria. During the statistical analysis, six most informative criteria were established: calcifications, contours, shape, depth-to-width ratio in the transverse scanning plane, state (differentiation) of the cortical and cerebral layers, echostructure. To create complexes (patterns) of ultrasonic signs, a combination of these signs was used among themselves, and five patterns were established. The first pattern, including the depth-to-width ratio in the transverse scanning plane and the echo structure, has a sensitivity (Se) of 97 %, diagnostic accuracy (Ac) of 96.5 %, area under the curve (AUC) of 96 %, the probability ranges from 95 to 99 %. The Se of the second pattern, including the ratio of depth to width in the transverse scanning plane, echostructure and shape, was 97.2 %, Ac – 96.8 %, AUC – 97.3 %, probability – 95–100 %. The third pattern, including the ratio of depth to width in the transverse scanning plane, nature, shape and contours, and the fourth pattern, including the following criteria, the ratio of depth to width in the transverse scanning plane, echostructure, shape, contours and differentiation into cortical and cerebral layers, have Se 96.9 %, Ac – 97.1 %, AUC – 98.7 %, probability – 88–100 %. The fifth pattern, including the ratio of depth to width in the transverse scanning plane, echostructure, shape; contours; state (differentiation) of the cortical and cerebral layers; calcinates, has Se – 99.6 %, Ac – 99.5 %, AUC – 99.9 %, probability – 94–100 %.</p></sec><sec><title>Conclusion</title><p>Conclusion. Five patterns of metastatic involvement of lymph nodes in PTC were found. The informative value of US increased from the first to the fifth pattern achieving a Se of 99.6 %, Ac of 99.5 %, AUC of 99.9 %. The probability ranged from 94 % to 100 %.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>метастаз</kwd><kwd>лимфатический узел</kwd><kwd>папиллярный рак щитовидной железы</kwd><kwd>ультразвуковое исследование</kwd><kwd>паттерн</kwd></kwd-group><kwd-group xml:lang="en"><kwd>metastasis</kwd><kwd>lymph node</kwd><kwd>papillary thyroid cancer</kwd><kwd>ultrasound examination</kwd><kwd>pattern</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">Пачес А.
