Люминальный рак молочной железы встречается в 60–80 % случаев и характеризуется высокой частотой метастазирования в кости, что определяет необходимость своевременного выявления отдаленных очагов. Традиционные методы визуализации имеют ограниченную чувствительность, особенно в отношении очагов малого размера. В связи с этим актуальна разработка высокочувствительных методов более ранней диагностики метастазов в кости. Перспективным направлением является таргетная радионуклидная визуализация рецептора гастрин-высвобождающего пептида (GRPR), гиперэкспрессия которого ассоциирована с рецептором эстрогена, с использованием радиофармацевтического лекарственного препарата (РФЛП) на основе антагонистов GRPR. Доклинические исследования продемонстрировали перспективность использования для этих целей РФЛП [99mTc]Tc-DB8. Цель исследования – демонстрация возможностей РФЛП [99mTc]Tc-DB8 в диагностике костных метастазов у больных люминальным РМЖ. Описание клинических случаев. Клинический случай № 1. Пациентка К., 51 год, диагноз: Рак правой молочной железы, IIIC стадия (T2N3M0), мультицентричный рост, метастатическое поражение аксиллярных и подключичных лимфоузлов. ОФЭКТ/КТ выполнена через 2 ч после внутривенного введения РФЛП [99mTc]Tc-DB8 в дозировке протеина 80 мкг. По результатам исследования помимо первичной опухоли и метастатических лимфоузлов выявлен высокий уровень аккумуляции препарата [99mTc]Tc-DB8 в проекции V ребра справа по средней аксиллярной линии. Повторный анализ компьютерных томограмм органов грудной клетки (КТ ОГК) подтвердил наличие очага литической деструкции, расцененного как возможный метастаз и взятого под наблюдение. При КТ ОГК в динамике в указанной проекции визуализировался участок неравномерных склеротических изменений, что интерпретировано как ответ на терапию. Клинический случай № 2. Пациентка Д., 42 года, диагноз: Рак правой молочной железы IV стадии (T1N1M1), метастаз в аксиллярный лимфоузел, множественные метастазы в костях. ОФЭКТ/КТ проведена через 2 ч после инъекции РФЛП [99mTc]Tc-DB8 в дозировке 80 мкг, при которой помимо визуализации первичного очага и метастатически измененного лимфоузла выявлена высокая аккумуляция РФЛП в проекции LII-SII, в подвздошной и седалищной костях, в заднем отрезке VII ребра справа. Заключение. Результаты клинического исследования с использованием препарата [99mTc]Tc-DB8 продемонстрировали высокую диагностическую эффективность метода в визуализации костных метастазов у больных люминальным РМЖ.</p></abstract><trans-abstract xml:lang="en"><p>Background. Luminal breast cancer, comprising 60–80 % of cases, is characterized by a high frequency of bone metastasis, necessitating continuous surveillance for early detection of distant metastases. Traditional imaging methods have limited sensitivity, especially for small lesions. Therefore, the development of highly sensitive methods for early diagnosis is relevant. Targeted radionuclide imaging of the gastrin-releasing peptide receptor (GRPR) using antagonist-based radiopharmaceuticals, such as [99ᵐTc]Tc-DB8 is a promising non-invasive method for detecting small lesions. The aim of the study was to demonstrate the potential of [99ᵐTc]Tc-DB8 for detecting bone metastases in patients with luminal breast cancer. Case report 1. A 51- year-old woman diagnosed with stage IIIC right breast cancer (T2N3M0), with multicentric growth, metastatic involvement of the axillary and subclavian lymph nodes, underwent SPECT/CT 2 hours after the intravenous administration of [99ᵐTc]Tc-DB8 at a protein dose of 80 μg. The detection of a high-uptake [99ᵐTc]Tc-DB8 lesion in the right 5th rib, confrmed as a lytic bone destruction on CT, indicated a high suspicion of bone metastasis. Followup chest CT showed an area of uneven sclerotic changes, interpreted as a response to therapy. Case report 2. A 42-year-old woman was diagnosed with stage IV right breast cancer (T1N1M1), metastatic involvement of the axillary lymph node, and multiple bone metastases. A SPECT/CT performed 2 hours after the intravenous injection of [99ᵐTc]Tc-DB8 at a dose of 80 μg revealed high uptake of the radiopharmaceutical in the primary tumor, metastatic lymph nodes, and extensive bone metastases. Specifcally, the radiopharmaceutical accumulated in the L2-S2 vertebrae, the right ilium and ischium, and the posterior segment of the 7th rib on the right, identifying these as metastatic sites. Conclusion. Results of the clinical study on [99ᵐTc]Tc-DB8 demonstrated its high effcacy in detecting bone metastases in patients with luminal breast cancer.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>люминальный рак молочной железы</kwd><kwd>DB8</kwd><kwd>GRPR</kwd><kwd>радионуклидная диагностика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>luminal breast cancer</kwd><kwd>DB8</kwd><kwd>GRPR</kwd><kwd>radionuclide diagnostics</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">Roy M., Fowler A.M., Ulaner G.A., Mahajan A.
