Молодые женщины чаще, чем женщины старшего возраста, имеют агрессивные молекулярные подтипы и позднюю стадию заболевания. Маммография имеет меньшую чувствительность в выявлении рака молочной железы у женщин с плотной молочной железой, а 2D-ультразвуковое исследование (2D-УЗИ) имеет ограничения, такие как высокий уровень навыков и опыта специалиста, затраты времени на проведение исследования. На сегодняшний день есть новая методика – автоматизированное объемное ультразвуковое сканирование молочных желез (3D-УЗИ), позволяющая получать изображения с высоким разрешением.</p><sec><title>Цель исследования</title><p>Цель исследования: сравнительный анализ диагностической эффективности УЗИ в 2D- и 3D-режиме у женщин в возрастной группе до 40 лет с высокой плотностью тканей молочной железы.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Проведено ретропроспективное клиническое одноцентровое исследование. С февраля 2019 г. по май 2023 г. было исследовано 1511 пациенток в возрасте до 40 лет. Пациентки были разделены на 2 группы. Пациентки, попавшие в группу А, проходили 2D-УЗИ, результаты исследования оценивались по классификации BI-RADS. Пациентки, попавшие в группу B, в дополнение к 2D-УЗИ, проходили 3D-УЗИ также с выставлением категории BI-RADS. По итогам исследования определялись положительная и отрицательная прогностическая ценность, чувствительность, специфичность и точность, а также составление предсказательной модели метода.</p></sec><sec><title>Результаты</title><p>Результаты. Метод УЗИ в группе А показал чувствительность 0,8, специфичность 1, отбалансированную точность 0,9 и площадь под кривой предсказательной модели 0,947, УЗИ в группе B 0,89, 0,98, 0,94 и 0,903 соответственно, УЗИ по всей выборке 0,87, 0,99, 0,93 и 0,916 соответственно. Метод 3D-УЗИ в группе B показал чувствительность 0.95, специфичность 0,99 и отбалансированную точность 0,97 и площадь под кривой предсказательной модели 0,968.</p></sec><sec><title>Выводы</title><p>Выводы. Диагностическая эффективность автоматизированного УЗИ молочных желез у пациенток до 40 лет сопоставима по показателю специфичности и лучше по показателю точности, чувствительности и обладает более высокой прогностической ценностью по сравнению с УЗИ в 2D-режиме. Метод 3D-УЗИ имеет преимущества в сравнении с 2D-УЗИ, а именно: воспроизводимость, операторонезависимость метода, сокращенное время проведения исследования, получение визуализации всего органа, улучшенная визуализация при мультицентричных и мультифокальных процессах, возможность оперативного планирования, возможность “двойного чтения” результатов.</p></sec></abstract><trans-abstract xml:lang="en"><p>Breast cancer is the most common cancer among women worldwide. Younger women are more likely than older women to have aggressive molecular subtypes and late-stage disease. Mammography has less sensitivity in detecting breast cancer in women with a dense breast, and 2D ultrasound (2D US) has limitations, such as the specialists high level of skill and experience and the time it takes to perform the examination. Nowadays, there is a new technique – automated volumetric ultrasound scanning of the breast (3D US), which allows you to obtain high-resolution images.</p><sec><title>Aim</title><p>Aim. To perform a comparative analysis of the diagnostic efficacy of 2D US and 3D US among women under 40 years of age with high breast tissue density.</p></sec><sec><title>Methods</title><p>Methods. A retro-prospective clinical single-center study. From February 2019 to May 2023, 1511 patients under the age of 40 were examined. The patients were divided into two groups. Patients in group A underwent 2D ultrasound, the results of the study were evaluated according to the BI-RADS classification. In addition to 2D ultrasound, the patients who were placed in group B underwent 3D US also with the BI-RADS category. Based on the results of the study, the positive and negative predictive value, sensitivity, specificity and accuracy, as well as the compilation of a predictive model of the method were determined.</p></sec><sec><title>Results</title><p>Results. The 2D US in group A showed sensitivity of 0.8, specificity 1, balanced accuracy of 0.9, and area under the predictive model curve of 0.947, US in group B 0.89, 0.98, 0.94, and 0.903, respectively, and US of the entire sample of 0.87, 0.99, 0.93, and 0.916, respectively. The 3D US in group B showed a sensitivity of 0.95, specificity of 0.99 and a balanced accuracy of 0.97 and an area under the predictive model curve of 0.968.</p></sec><sec><title>Conclusion</title><p>Conclusion. The diagnostic efficiency of 3D US of the mammary glands in patients under 40 years of age is comparable in terms of specificity and is better in terms of accuracy, sensitivity and a better prognostic model of the method compared to US examination in 2D mode. The 3D US method has advantages in comparison with 2D US examination, namely reproducibility, operator independence of the method, reduced examination time, obtaining visualization of the entire organ, improved visualization in multicentric and multifocal processes, the possibility of operational planning, the possibility of “double reading” of the results.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рак молочной железы</kwd><kwd>ультразвуковое исследование</kwd><kwd>автоматизированное объемное сканирование молочных желез</kwd><kwd>молодые женщины</kwd></kwd-group><kwd-group xml:lang="en"><kwd>breast cancer</kwd><kwd>ultrasound</kwd><kwd>automated breast volumetric scan</kwd><kwd>young women</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">Shapira N.
