Необходим поиск диагностических маркеров, которые могли бы прогнозировать риск и локализацию возможных гематогенных метастазов. Одним из подходов к решению такой задачи является изучение экспрессии интегринов, которые участвуют в процессах, обусловливающих прогрессирование карцином.</p><p>Цель исследования – изучить ассоциацию экспрессии интегринов в ткани опухоли при гематогенном метастазировании у больных раком молочной железы.</p><sec><title>Материал и методы</title><p>Материал и методы. В исследование включено 72 больных (средний возраст – 51 ± 12 лет) с неспецифицированной инвазивной протоковой карциномой молочной железы T1–4N0–3M0–1 стадии, со всеми молекулярно-биологическими подтипами (люминальный А, люминальный Б, HER2-позитивный и трижды негативный). Биопсийный материл исследовался до начала противоопухолевого лечения. Экспрессию интегринов в опухолевых клетках оценивали иммуногистохимическими методами. Использовались антитела CD61 (интегрин β3, Invitrogen, США), CD104 (интегрин β4, Invitrogen, США), CD51 (интегрин αV, Invitrogen, США).</p></sec><sec><title>Результаты</title><p>Результаты. У пациенток с гематогенными метастазами чаще выявлялась цитоплазматическая, но не цитоплазматическая/ мембранная колокализация экспрессии CD61 (p=0,036). Цитоплазматическая и мембранная колокализация CD104 чаще выявлялась при метастатическом поражении головного мозга по сравнению с поражением легких (р=0,026) и костей (р=0,036). Экспрессия интегрина CD51 чаще ассоциировалась с метастазами в легких, чем с метастатическим поражением костей (р=0,045).</p></sec><sec><title>Заключение</title><p>Заключение. Частота и локализация гематогенных метастазов у больных раком молочной железы ассоциированы с наличием и локализацией в опухолевой клетке экспрессии CD61, CD104 и CD51.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Distant hematogenous metastasis is the leading cause of tumor-related death from breast cancer. To prevent metastasis, prognostic markers for predicting the risk and location of hematogenous metastases are required. In this regard, it is of great importance to study the expression of integrins involved in the most important processes that determine the progression of cancer.</p><p>The objective of the study was to investigate the association of integrin expression in tumor tissue with hematogenous metastasis of patients with breast cancer.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. The study included 72 patients (average age – 51 ± 12 years) with stage T1–4N0–3M0–1 unspecifed invasive ductal breast carcinoma, with all molecular biological subtypes (luminal A, luminal B, HER2-positive and triple negative). The biopsy material was examined before the start of antitumor treatment. Expression of integrins in tumor cells was assessed by immunohistochemical methods. Antibodies CD61 (integrin β3, Invitrogen, USA), CD104 (integrin β4, Invitrogen, USA), CD51 (integrin αV, Invitrogen, USA) were used.</p></sec><sec><title>Results</title><p>Results. In patients with hematogenous metastases, cytoplasmic rather than cytoplasmic/membrane colocalization, CD61 expression was more often detected (p=0.036). Cytoplasmic and membrane colocalization of CD104 was more frequently detected in brain metastases compared to lung (p=0.026) and bone (p=0.036) metastases. Expression of CD51 integrin was more often associated with lung metastases than with bone metastases (p=0.045).</p></sec><sec><title>Conclusion</title><p>Conclusion. The frequency and localization of hematogenous metastases in breast cancer patients are associated with the presence and localization of CD61, CD104 and CD51 expression in the tumor cell.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рак молочной железы</kwd><kwd>интегрины</kwd><kwd>гематогенные метастазы</kwd><kwd>первично-метастатический рак</kwd></kwd-group><kwd-group xml:lang="en"><kwd>breast cancer</kwd><kwd>integrins</kwd><kwd>hematogenous metastases</kwd><kwd>primary metastatic cancer</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование было поддержано Российским научным фондом (грант № 21-15-00140 «Прогнозирование локализации гематогенных метастазов при раке молочной железы»).</funding-statement><funding-statement xml:lang="en">The study was supported by the Russian Science Foundation (grant No. 21-15-00140 “Prediction of sites of breast cancer hematogenous metastases”).</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">Злокачественные новообразования в России в 2020 году (заболеваемость и смертность).
