Установлено, что степень инфильтрации опухоли иммунными клетками и их состав напрямую связаны с развитием заболевания и ответом на терапию. Многопараметровая проточная цитометрия (ПЦ) позволяет проводить исследования субпопуляционного состава TILs.</p><p>Целью работы явилось изучение особенностей лимфоидного микроокружения (TILs) опухоли больных первично-операбельным и местно-распространенным РМЖ методом ПЦ.</p><p>В исследование включены больные первично-операбельным РМЖ (группа 1, n = 121) и местно-распространенным (группа 2, n = 80), получающим лечение в ФГБУ «НМИЦ онкологии им. Н.Н. Блохина» Минздрава России. Исследовали TILs опухоли, полученной интраоперационно или путем корр-биопсии. Больные были разделены на 3 подгруппы: 1-я подгруппа – степень инфильтрации до 1%, 2-я подгруппа – степень инфильтрации от 1% до 10%, 3-я подгруппа – степень инфильтрации свыше 10%.</p><p>Для больных РМЖ 1-й группы оказалось характерным высокая функциональная активность и концентрация клеток эффекторного звена при низкой степени инфильтрации опухоли, а по мере нарастания количества лимфоцитов в опухоли отмечалось увеличение пула CD4+ клеток и CD4 Treg одновременно со снижением количества и функциональной активности эффекторных TILs. Во 2-й группе не выявлено достоверных различий клеточного состава TILs в подгруппах со слабой и средней степенью инфильтрации, а вариант с инфильтрацией более 10% был зафиксирован только у одной пациентки. Отсутствие связи субпопуляционной структуры TILs в подгруппах с разной степенью инфильтрации опухоли свидетельствует о сходном характере локального иммунного ответа при местнораспространенном РМЖ.</p><p>Таким образом, в отличие от больных местно-распространенным раком молочной железы, у пациенток первично-операбельным РМЖ прослеживается изменение типа локального иммунного ответа от эффекторного к регуляторному. Высокая степень инфильтрации опухоли характеризуется истощением функции клеток эффекторного звена.</p></abstract><trans-abstract xml:lang="en"><p>Despite the success in early diagnosis and drug treatment of breast cancer patients, long-term treatment results are still unsatisfactory, and in this regard, the role of research aimed at studying various mechanisms of development of this disease is increasing. It has been established that the degree of tumor infiltration by immune cells and their composition are directly related to the development of the disease and the response to therapy. Multiparameter flow cytometry (PC) allows studies of the subpopulation composition of TILs. The aim of the work was to study the features of the lymphoid microenvironment (TILs) of tumors in patients with primary operable and locally advanced breast cancer by PC. The study included patients with primary operable breast cancer (group 1, n = 121) and locally advanced (group 2, n = 80) receiving treatment at the N. N. Blokhin NMRCO. The TILs of a tumor obtained intraoperatively or by a core-biopsy were examined. The patients were divided into 3 subgroups: 1 subgroup – the degree of infiltration up to 1%, 2 subgroup – the degree of infiltration from 1 to 10%, and 3 subgroup – the degree of infiltration over 10%. Patients of group 1 were characterized by high functional activity and concentration of effector cells with a low degree of tumor infiltration, and as the number of lymphocytes in the tumor increased, an increase in the pool of CD4+ cells and CD4 Treg was noted simultaneously with a decrease in the number and functional activity of effector TILs. In group 2 were no significant differences in the cellular composition of TILs in subgroups with a weak and moderate degree of infiltration, and a variant with infiltration of more than 10% was recorded in only one patient. The lack of association of the TILs subpopulation structure in subgroups with varying degrees of tumor infiltration indicates a similar nature of the local immune response in locally advanced breast cancer.</p><p>Thus, unlike patients with locally advanced breast cancer, patients with primary operable breast cancer show a change in the type of local immune response from effector to regulatory. A high degree of tumor infiltration is characterized by depletion of effector cell function.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>цитометрия</kwd><kwd>субпопуляции лимфоцитов</kwd><kwd>микроокружение опухоли</kwd><kwd>TILs</kwd><kwd>рак молочной железы</kwd><kwd>иммунофенотип</kwd></kwd-group><kwd-group xml:lang="en"><kwd>flow cytometry</kwd><kwd>lymphocyte subpopulations</kwd><kwd>tumor microenvironment</kwd><kwd>TILs</kwd><kwd>breast cancer</kwd><kwd>immunophenotype</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">Состояние онкологической помощи населению России в 2022 году / Под ред.
