Частота метастатического поражения регионарных лимфатических узлов при дифференцированном раке щитовидной железы (ДРЩЖ) высока и составляет 50–60%, особенно при папиллярной форме. В среднем у 30–40% пациентов выявляются скрытые метастазы в лимфатических узлах VI группы после профилактической центральной шейной лимфодиссекции (ЦШЛД), которые не были обнаружены на этапе предоперационной диагностики по данным ультразвукового исследования и компьютерной томографии.</p></sec><sec><title>Цель</title><p>Цель. Определить факторы, ассоциированные с повышенным риском регионарного метастазирования, для уточнения показаний к выполнению ЦШЛД.</p></sec><sec><title>Методы</title><p>Методы. В исследование включено 105 пациентов с клиническими стадиями ДРЩЖ Т1-2N0М0, которым в ФГБУ “Российский научный центр рентгенорадиологии” Минздрава России с 2012 по 2017 г. выполнена тиреоидэктомия с профилактической билатеральной ЦШЛД. Преобладали пациенты старше 45 лет – 66 (62,9%). Обработка информации осуществлялась в таблицах Microsoft Access и Excel, для анализа количественных признаков использовался однофакторный дисперсионный анализ, а качественных – критерий c-квадрат, многофакторный анализ проводился с помощью программы SPSS 20.</p></sec><sec><title>Результаты</title><p>Результаты. Скрытые метастазы выявлены у 32 (30,5%) пациентов. Мультифокальный рост отмечен в 29 (27,6%) случаях, отсутствие капсулы опухолевого узла – у 65 (61,9%), инвазия капсулы щитовидной железы (ЩЖ) – у 38 (36,2%) больных. 69 (65,7%) пациентов имели фоновые заболевания ЩЖ. По данным многофакторного анализа достоверными независимыми предикторами скрытого метастатического поражения лимфатических узлов центральной группы шеи явились: инвазия анатомической капсулы ЩЖ (р = 0,003), возраст пациентов ≤45 лет (р = 0,005), неинкапсулированный вариант карциномы (р = 0,007).</p></sec><sec><title>Заключение</title><p>Заключение. Применение тиреоидэктомии в сочетании с ЦШЛД позволило провести рестадирование у 46,7% больных за счет выявления прорастания капсулы ЩЖ (28,6%) и скрытых метастазов в лимфатических узлах VI группы (30,5%).</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. The regional lymph node metastasis in differentiated thyroid cancer (DTC) is still very high: 50–60%, especially in papillary form. Averagely, after central neck lymph node dissection (CNLD), in 30–40% cases “hidden” metastasis in lymph nodes of VI zone of neck were revealed. But they were not indicated by preoperative diagnostic procedures: ultrasound (US) and computer tomogpraphy (CT).</p></sec><sec><title>Aims</title><p>Aims. To define the factors associated with the increased risk of lymph node metastasis for specification of indications to CNLD performance.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study covers 105 patients with clinical stages of DTC T1-2N0M0, who received a thyroidectomy (TE) with preventive bilateral CNLD in RSCRR since 2012 till 2017. Patients older than 45 y.o. prevailed (66 patients (62.9%)). Data processing was carried out in a Microsoft Access database, a one-factor dispersion analysis was used for the analysis of the quantitative signs, and a c-square criterion was used for the qualitative ones.</p></sec><sec><title>Results</title><p>Results. The “hidden” metastasizes are founded by 32 (30.5%) patients. Multifocality is registered in 29 (27.6%) cases, lack of the tumor node capsule is registered in 65 (61.9%) and an invasion of the thyroid gland capsule is registered in 38 (36.2%) patients. Background diseases of the thyroid gland (TG) have 69 (65.7%) patients. According to the multifactorial analysis reliable independent predictors of the “hidden” metastasis of central neck lymph nodes were invasion of the anatomic capsule of TG (р = 0.003), age of patients ≤45 y.o. (р = 0.005), nonincapsulated form of tumor (р = 0.007).</p></sec><sec><title>Conclusion</title><p>Conclusion. Use of TE in combination with CNLD allowed to restage at 46.7% of patients due to TG capsule invasion (28.6%) and “hidden” metastasis in VI group lymph nodes (30.5%) identification.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>высокодифференцированный рак щитовидной железы</kwd><kwd>скрытый метастаз</kwd><kwd>центральная шейная лимфодиссекция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>thyroid cancer</kwd><kwd>neck dissection</kwd><kwd>lymphatic metastasis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовом обеспечении ФГБУ “Российский научный центр рентгенорадиологии” Минздрава России.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Morris LG, Sikora AG, Tosteson TD, Davies L.
