На фоне улучшения диагностики в течение последних декад во всем мире наблюдается рост заболеваемости папиллярной микрокарциномой щитовидной железы (ПМЩЖ). Существует множество различных мнений о степени агрессивности данной группы опухолей, а также о тактике ведения больных ПМЩЖ.</p></sec><sec><title>Цель</title><p>Цель. Выявить факторы прогноза, отвечающие за особенности клинического течения ПМЩЖ, в том числе более агрессивного.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование включены 109 пациентов с папиллярным раком щитовидной железы с размером опухоли ≤1 см, а также отсутствием клинических данных о регионарных и отдаленных метастазах. Всем больным на первом этапе проведено хирургическое лечение в объеме тиреоидэктомии с двусторонней центральной шейной лимфодиссекцией. У 26,6% пациентов при гистологическом исследовании выявлено метастатическое поражение лимфатических узлов центральной группы. Скрытые метастазы выявлены у 24,2% женщин и 43% мужчин, у 36,7% пациентов &lt;55 и у 14,3% ≥55 лет, у 29,5% — с отсутствием капсулы узла и у 19,3% — с инкапсулированными опухолями, у 48,1% — с мультицентрическим ростом и у 19,5% — с солитарным новообразованием, у 21,7% — с размером опухоли ≤0,5 см и у 27,9% — с узлом 0,6–1 см, у 24% — с отсутствием прорастания капсулы щитовидной железы и у 31% — с наличием экстратиреоидной инвазии, у 21% — с типичным, у 26% — с фолликулярным и у 43%  — со смешанным вариантом папиллярного рака. 95 пациентам проведена радиойодтерапия. Дополнительных метастазов у них выявлено не было.</p></sec><sec><title>Результаты</title><p>Результаты. При проведении однофакторного анализа основными признаками, влияющими на развитие метастазов в центральной зоне, явились: возраст до 55 лет (p=0,009; χ2=6,919) и мультицентрическое поражение (p=0,004; χ2=8,530), при многофакторном анализе аналогичным образом — возраст моложе 55 лет (р=0,000; Exp B=0,011; ДИ 95,0% 0,001–0,106) и многофокусность (р=0,027; Exp B=2,686; ДИ 95,0% 1,119–6,448).</p></sec><sec><title>Заключение</title><p>Заключение. ПМЩЖ, на наш взгляд, не следует рассматривать как отдельную группу опухолей, а определение тактики лечения должно опираться не только на размеры опухоли, но и на другие клинические и, в перспективе, биологические параметры.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Over the past decades an increase in the incidence of papillary thyroid microcarcinoma (PTMC) has been observed throughout the world owing to the improved diagnostics. There are many different opinions about the aggressiveness degree of this group of tumors, as well as about the tactics of managing patients with PTMC.</p><p>Aim of the study is the identification of the prognostic factors responsible for the features of the clinical course, including the more aggressive one.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A study was carried out with a detailed analysis of a group of patients with papillary thyroid cancer ≤1 cm in size and the existing clinical data of regional and distant metastases. All patients underwent thyroidectomy with bilateral central cervical lymph node dissection. Factors such as gender, patient age, bilaterality, extrathyroid extension, the presence or absence of a capsule around the tumor node, the absence or presence of metastases in the central part were assessed. In 26.6% histological examination revealed metastatic lesions of the central group lymph nodes. Latent metastases were detected in 24.2% of women and 43% of men, in 36.7% of patients &lt;55 and in 14.3% of patients ≥ 55 years, in 29.5% with the absence of the node capsule and in 19.3% with encapsulated tumors, in 48.1% with multicentric growth and in 19.5% with a solitary neoplasm, in 21.7% with a tumor size ≤0.5 cm and in 27.9% with a node of 0.6–1 cm, in 24% with the absence of invasion of the thyroid capsule and in 31% with the presence of extrathyroid invasion, in 21% of patients with typical, in 26% with follicular and 43% with mixed papillary cancer. 95 patients received radioiodine therapy. No additional metastases were found in them.</p></sec><sec><title>Results</title><p>Results. When conducting univariate analysis, the main signs influencing the development of metastases in the central zone were age up to 55 years (p = 0.009, χ2 = 6.919) and multicentric neoplasm (p = 0.004, χ2 = 8.530); in multivariate analysis, similarly, age younger 55 years (p = 0.000, Exp B = 0.011, CI 95.0% 0.001–0.106) and multifocality (p = 0.027, Exp B = 2.686, CI 95.0% 1.119–6.448).</p></sec><sec><title>Conclusion</title><p>Conclusion. PTMC is not a separate group or tumor morphotype, and the determination of treatment tactics for this group of patients should be based not only on the size of the tumor, but on the clinical and biological parameters of the tumor.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>папиллярная микрокарцинома щитовидной железы</kwd><kwd>факторы риска</kwd><kwd>метастазы в лимфатические узлы</kwd><kwd>центральная шейная лимфодиссекция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>рapillary thyroid microcarcinoma</kwd><kwd>Risk factors</kwd><kwd>Lymph node metastasis</kwd><kwd>Central lymph node dissection</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовом обеспечении ФГБУ «Российский научный центр рентгенора- диологии» 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">Pacini F.
