Папиллярный рак щитовидной железы (ПРЩЖ) является наиболее распространенной формой дифференцированного рака щитовидной железы. Рост заболеваемости раком щитовидной железы совпадает с увеличением распространенности ожирения и метаболических нарушений, однако их влияние на риск рецидивирования остается недостаточно изученным.</p><p>   Цель исследования – оценить роль ожирения и связанных метаболических нарушений в формировании риска рецидива ПРЩЖ.</p></sec><sec><title>   Материалы и методы</title><p>   Материалы и методы. В исследование были включены 145 пациентов с верифицированным ПРЩЖ, прооперированных до 2023 г. Проведен ретроспективный анализ клинических, антропометрических и метаболических параметров. Участники были разделены на 2 группы: группа 1 – пациенты с отсутствием рецидива заболевания в течение 5 лет и более, группа 2 – с рецидивом ПРЩЖ. Оценивались индекс массы тела (ИМТ), окружность талии (ОТ), длительность ожирения, показатели углеводного и липидного обмена, индекс HOMA-IR. В рамках исследования были выполнены ROC-анализ и логистическая регрессия.</p></sec><sec><title>   Результаты</title><p>   Результаты. Рецидив заболевания был отмечен у 16 (11 %) пациентов, в среднем через 8,9 (4,3–11,2) года после первичного хирургического вмешательства. У больных с рецидивом установлены более высокие значения ИМТ (32,23 против 26,88 кг/м²; p &lt; 0,001), ОТ (99,03 против 86,02 см; p &lt; 0,001), HOMA-IR (5,57 против 3,25; p &lt; 0,001) и более длительный анамнез ожирения (19,02 против 10 лет; p &lt; 0,001). Пороговые значения этих параметров, ассоциированные с повышенным риском рецидива ПРЩЖ, оказались следующими: ИМТ ≥ 28,13 кг/м², длительность ожирения ≥12 лет, HOMA-IR ≥ 3,90, ОТ ≥ 90 см. Логистическая регрессия показала независимый вклад всех метаболических факторов в риск рецидива.</p></sec><sec><title>   Заключение</title><p>   Заключение. Ожирение, его длительность и выраженность метаболических нарушений, прежде всего инсулинорезистентность, являются значимыми предикторами рецидивирования ПРЩЖ. Выявленные пороговые значения могут использоваться для стратификации риска и оптимизации наблюдения пациентов. При этом все пациенты до и после операции имели абдоминальное ожирение, что позволяет предположить, что персистирующее ожирение выступает нетолько фактором риска развития, но и мощным драйвером, поддерживающим риск рецидива в течение многих лет после лечения.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>   Relevance</title><p>   Relevance. Papillary thyroid cancer (PTC) is the most common form of differentiated thyroid cancer. The increasing incidence of thyroid cancer coincides with the growing prevalence of obesity and metabolic disorders; however, their impact on the risk of recurrence remains in-sufficiently studied.</p></sec><sec><title>   Objective</title><p>   Objective. To evaluate the role of obesity and associated metabolic disorders in determining the risk of PTC recurrence.</p></sec><sec><title>   Materials and Methods</title><p>   Materials and Methods. The study included 145 patients with verified prostate cancer who underwent surgery until 2023. A retrospective analysis of clinical, anthropometric, and metabolic parameters was performed. The patients were divided into 2 groups: Group 1 – the patients with absence of recurrence of the disease for 5 years or more, Group 2 – the patients with a recurrence of prostate cancer. Body mass index (BMI), waist circumference (WC), duration of obesity, indicators of carbohydrate and lipid metabolism, and the HOMA-IR index were evaluated. ROC analysis and logistic regression were performed.</p></sec><sec><title>   Results</title><p>   Results. Disease recurrence was observed in 16 (11 %) patients, on average 8.9 (4.3–11.2) years after the primary surgical intervention. Patients with recurrence had higher values of BMI (32.23 vs. 26.88 kg/m²; p &lt; 0.001), WC (99.03 vs. 86.02 cm; p&lt; 0.001), HOMA-IR (5.57 vs. 3.25; p &lt; 0.001), and a longer history of obesity (19.02 vs. 10 years; p &lt; 0.001). Threshold values associated with an increased risk of recurrence were: BMI ≥ 28.13 kg/m², obesity duration ≥ 12 years, HOMA-IR ≥ 3.90, WC ≥ 90 cm. Logistic regression showed an independent contribution of all metabolic factors to the risk of recurrence.</p></sec><sec><title>   Conclusion</title><p>   Conclusion. Obesity, its duration, and the severity of metabolic disorders, primarily insulin resistance, are significant predictors of PTC recurrence. The identified threshold values can be used for risk stratification and optimization of patient follow-up. Moreover, all patients had abdominal obesity before and after surgery, suggesting that persistent obesity acts not only as a risk factor for development but also as a powerful driver sustaining the risk of recurrence for many years after treatment.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>дифференцированный рак щитовидной железы</kwd><kwd>рецидив</kwd><kwd>ожирение</kwd><kwd>инсулинорезистентность</kwd><kwd>HOMA-IR</kwd><kwd>метаболический синдром</kwd><kwd>прогноз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>differentiated thyroid cancer</kwd><kwd>recurrence</kwd><kwd>obesity</kwd><kwd>insulin resistance</kwd><kwd>HOMA-IR</kwd><kwd>metabolic syndrome</kwd><kwd>prognosis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Отсутствует</funding-statement><funding-statement xml:lang="en">None</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">Клинические рекомендации.
