В исследование включались пациентки до начала специфического лечения или на фоне неоадъювантной гормонотерапии, с ранее определенной экспрессией РЭ по результатам ИГХ. 14 пациенткам была проведена ПЭТ/КТ с 18F-ФДГ с разницей в 2–7 дней между обоими ПЭТ/КТ.</p></sec><sec><title>   Результаты</title><p>   Результаты: В нашем исследовании среднее значение SUVmax в первичном опухолевом очаге составило 4,8, наиболее низкое значение SUVmax = 1,61, а наиболее высокий SUVmax = 18,86. Накопление 18F-ФЭС, расцененное как подозрительное в отношении метастатического поражения в подмышечных лимфоузлах на стороне поражения, было выявлено у 16 пациенток (56 %), средние значения SUVmax = 5,2, наиболее низкий уровень SUVmax = 0,99, наивысший SUVmax = 11,54. При последующем проведении гистологического исследования опухолевые изменения в подмышечных лимфоузлах были подтверждены у 16/16 пациенток.</p></sec><sec><title>   Заключение</title><p>   Заключение: ПЭТ/КТ с 18F-ФЭС является диагностическим методом неинвазивной оценки экспрессии РЭ в опухолевых очагах, который может дополнить данные традиционных диагностических методов и имеет значительный клинический потенциал. В нашем исследовании результаты ПЭТ/КТ с 18F-ФЭС совпадали с данными иммуногистохимического исследования в 100 % случаев.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>   Purpose</title><p>   Purpose: To evaluate the informativity of PET/CT with 18F-FES in determining estrogen receptor (ER) positivity in breast tumor tissue, as well as in regional lymph nodes or distant metastatic foci.</p></sec><sec><title>   Material and methods</title><p>   Material and methods: The data of 30 patients who underwent PET/CT with 18F-FES performed at the stage of primary diagnosis were retrospectively analyzed. The study included patients before the start of specific treatment or on the background of neoadjuvant hormone therapy, with previously determined expression of ER according to the results of IGC. 14 patients underwent 18F-FDG PET/CT with 2–7 days difference between both PET/CT.</p></sec><sec><title>   Results</title><p>   Results: In our study, the mean SUVmax value in the primary tumor focus was 4.8, the lowest SUVmax = 1.61, and the highest SUVmax = 18.86. 18F-FES accumulation considered suspicious for metastatic lesion in axillary lymph nodes on the affected side was detected in 16 patients (56 %), mean SUVmax = 5.2, lowest SUVmax = 0.99, highest SUVmax = 11.54. On subsequent histological examination, tumor changes in axillary lymph nodes were confirmed in 16/16 patients.</p></sec><sec><title>   Conclusion</title><p>   Conclusion: PET/CT with 18F-FES is a diagnostic method for noninvasive evaluation of ER expression in tumor foci, which can complement the data of traditional diagnostic methods and has a significant clinical potential. In our study, the results of PET/CT with 18F-FES coincided with the data of immunohistochemical study in 100 % of cases.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ПЭТ</kwd><kwd>ПЭТ/КТ</kwd><kwd>рак молочной железы</kwd><kwd>18F-ФЭС</kwd><kwd>ФЭС</kwd><kwd>экспрессия рецепторов эстрогена</kwd></kwd-group><kwd-group xml:lang="en"><kwd>PET</kwd><kwd>PET/CT</kwd><kwd>breast cancer</kwd><kwd>18F-FES</kwd><kwd>ER-expression</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено без спонсорской поддержки</funding-statement><funding-statement xml:lang="en">The study had no sponsorship</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">Sung H, Ferlay J, Siegel RL, Laversanne M, Soerjomataram I, Jemal A, Bray F.
