Tumors can be muscle invasive and non-muscle invasive. Recently, tumor microenvironment (TME) became a focus of investigation in malignant tumors of the bladder. According to the currently available data, TME is a specific environment crating optimal conditions for carcinogenesis in the neoplastic lesion. The main parts of TME are extracellular matrix and stroma including vasculature, stromal, and immune cells. Additionally, TME includes cytokines, chemokines, and other compounds activating signal pathways necessary for tumor cells. Tumor-associated macrophages (TAMs) are being extensively studied as representatives of TME in solid tumors of varying locations. These macrophages can be classified into 2 phenotypes: M1 (pro-inflammatory and antitumor) and M2 (anti-inflammatory and protumor). The phenotypes perform different roles, and M2 macrophages regulate the most important processes of oncogenesis (invasion, proliferation, neoangiogenesis, etc.). In the context of bladder cancer, M2 macrophages are the most significant as they are the most numerous TAMs in TME.</p><p><bold>Aim</bold>. To study the role of tumor-associated macrophages in development of bladder tumors, as well as prognostic value of these macrophages.</p></abstract><trans-abstract xml:lang="ru"><p>Рак мочевого пузыря занимает 2-е место в структуре онкоурологических заболеваний во всем мире. выделяют мышечно-инвазивную и немышечно-инвазивную формы опухоли. в последнее время большое внимание уделяется изучению микроокружения опухоли (МО) при злокачественных новообразованиях мочевого пузыря. Согласно имеющимся на сегодняшний день данным, МО представляет собой специфическую среду, создающую оптимальные условия для канцерогенеза в неопластическом очаге. Основными частями МО являются внеклеточный матрикс и строма, которая включает сосуды, стромальные и иммунные клетки. помимо данных структур в состав МО входят цитокины, хемокины и другие соединения, способные обеспечивать активацию необходимых для опухолевых клеток сигнальных путей. Макрофаги, ассоциированные с опухолью (МАО), - активно изучаемые представители МО при солидных злокачественных новообразованиях различных локализаций. эти макрофаги подразделяют на 2 фенотипа: M1 (провоспалительные и противоопухолевые) и M2 (противовоспалительные и проопухолевые). Роль каждого фенотипа различна, при этом макрофаги M2 участвуют в регуляции важнейших процессов онкогенеза (инвазии, пролиферации, неоангиогенезе и т. д.). в аспекте изучения рака мочевого пузыря наибольшую значимость имеют макрофаги M2, которые являются самыми многочисленными представителями МАО в составе МО.</p><p><bold>Цель исследования</bold> - изучение роли макрофагов, ассоциированных с опухолью, в развитии злокачественных опухолей мочевого пузыря, а также их прогностической ценности.</p></trans-abstract><kwd-group xml:lang="en"><kwd>tumor associated macrophages</kwd><kwd>muscle-invasive bladder cancer</kwd><kwd>non- muscle-invasive bladder cancer</kwd><kwd>tumor microenvironment</kwd><kwd>cancerogenesis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>макрофаги</kwd><kwd>ассоциированные с опухолью</kwd><kwd>мышечно-инвазивный рак мочевого пузыря</kwd><kwd>немышечно-инвазивный рак мочевого пузыря</kwd><kwd>микроокружение опухоли</kwd><kwd>канцерогенез</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Antoni S., Ferlay J., Soerjomataram I. et al.
