Группу исследования составили 107 пациенток с раком молочной железы (РМЖ), гистотип опухоли в 100% случаев соответствовал по морфологии инвазивной карциноме неспецифического типа (инвазивная протоковая карцинома). Предоперационное лечение больные не получали. В каждом случае выполняли морфологическое исследование образцов первичной опухоли и лимфатических узлов аксиллярной клетчатки, полученных в результате проведения оперативного этапа лечения (радикальная мастэктомия или секторальная резекция молочной железы с аксиллярной лимфаденэктомией). Иммуногистохимически оценивали показатели экспрессии маркеров интегринов β1 и β3 в ткани первичной опухоли.Результаты. Исследование продемонстрировало, что увеличение степени злокачественности карциномы молочной железы ассоциировано с уменьшением частоты случаев с наличием позитивной экспрессии интегрина β1 и с увеличением частоты случаев с позитивной экспрессией интегрина β3. Метастазы в лимфатических узлах значимо реже определяли при наличии позитивной экспрессии интегрина β1 в альвеолярных и солидных структурах по сравнению со случаями негативной экспрессии маркера в аналогичных структурах (48%; χ2 = 3,5; р = 0,05 и 48%; χ2 = 4,8; р = 0,02 соответственно). Лимфогенные метастазы регистрировали статистически значимо чаще при наличии позитивной экспрессии интегрина β3 в дискретных группах клеток по сравнению со случаями, в которых экспрессия изучаемого маркера в описанных структурах была негативной (47 и 23% соответственно; χ2 = 5,1; р = 0,02).Заключение. Результаты работы показали наличие взаимосвязей между морфологической гетерогенностью опухоли и показателями экспрессии интегринов β1 и β3 в паренхиматозных структурах новообразования, выявили зависимость описанных параметров с частотой лимфогенной диссеминации у пациенток с РМЖ. Полученные в результате проведенного исследования данные расширяют и дополняют известные ранее сведения, указывают на возможность оценки маркеров в качестве потенциальных факторов прогноза течения онкологического заболевания.</p></abstract><trans-abstract xml:lang="en"><p>Objective. To study β1 and β3 integrin expression in nonspecific invasive breast carcinoma and to find the associations with parameters of tumor morphological heterogeneity and lymphatic dissemination.Material and Methods. Study group comprised 107 patients with breast cancer. Histological type of tumor corresponded to invasive carcinoma of a nonspecific type (invasive ductal carcinoma) in 100% of cases. Patients did not receive any preoperative treatment. In each case, we performed morphological examination of samples of primary tumor and axillary lymph nodes obtained at the surgical stage of treatment (radical mastectomy or sectoral resection of mammary gland with axillary lymphadenectomy). The parameters of β1 and β3 integrin expression in primary tumor tissue were assessed by immunohistochemistry.Results. The study demonstrated that an increase in the degree of malignancy of breast carcinoma was associated with a decrease in the incidence of positive expression of β1 integrin as well as with an increase in the incidence of positive expression of β3 integrin. Metastases in lymph nodes were significantly less frequently detected in the presence of positive expression of β1 integrin in the alveolar and solid structures compared with the cases of absent expression of the marker in similar structures (48%; χ2 = 3.5; p = 0.05 and 48%; χ2 = 4.8; p = 0.02, respectively). Lymphogenic metastasis were detected significantly more often in cases with positive expression of β3 integrin in discrete groups of cells compared with the cases where the expression of study marker in the described structures was absent (47 and 23%, respectively; χ2 = 5.1; p = 0.02).Conclusion. The results of work showed the presence of relationships between the morphological heterogeneity of the tumor and the parameters of β1 and β3 integrin expression in the parenchymal structures of the neoplasm. The study showed the association of described parameters with the frequency of lymphatic dissemination in patients with breast cancer. Obtained data expand and support previously known evidence and suggest the possibility of assessing the markers as potential prognostic factors predicting the course of cancer.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак молочной железы</kwd><kwd>интегрины β1 и β3</kwd><kwd>морфологическая гетерогенность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>breast cancer</kwd><kwd>β1 and β3 integrins</kwd><kwd>morphological tumor heterogeneity</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке гранта Президента Российской Федерации НШ-2701.2020.7 «Разработка новых подходов к прогнозированию течения карцином молочной железы и легких с учетом морфологической и молекулярно-генетической гетерогенности опухоли».</funding-statement><funding-statement xml:lang="en">The study was supported by Grant of the President of the Russian Federation No. НШ-2701.2020.7 “Development of new approaches to predicting the course of breast carcinomas based on morphological and molecular-genetic tumor heterogeneity”.</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">Blandin A.F., Renner G., Lehmann M., Lelong-Rebel I., Martin S., Dontenwill M. β1 Integrins as therapeutic targets to disrupt hallmarks of cancer.
