Внедрение в практику иммунопрепаратов в терапии рака требует тщательного анализа биологических особенностей опухоли. Поэтому изучение иммунофенотипа опухоли является ведущим научным направлением. Молекулы главного комплекса гистосовместимости рассматриваются как перспективные маркеры для оценки возможности применения иммунотерапии.  </p></sec><sec><title>Цель</title><p>Цель. Изучение иммунофенотипа первичной опухоли при молекулярных подтипах рака молочной железы и анализ его в зависимости от частоты поражения костного мозга.  </p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование включены 99 больных раком молочной железы. Изучены образцы опухолевой ткани и костного мозга. Стадии: Т1 (51,5 %), Т2 (44,4 %), Т3 (2,0 %). Метастатическое поражение лимфоузлов (N+) отмечено в 39,4 % (n = 39) случаев. Иммунофенотипирование опухоли проводилось на криостатных срезах методом иммунофлуоресценции. Использованы антитела к HLA-I, HLA-II, KL1, ФИТЦ-меченые F(аb2) –фрагменты антисыворотки (Becton Dickinson, США). Костный мозг изучался морфологическим (микроскоп Zeiss, Axioskop, Германия) и иммунологическим методами (проточная цитометрия, FACS Canto II, США), анализ данных – программа Kaluza Analysis 2.1. Использованы моноклональные антитела СD45, EPCAM (Becton Dickinson, США). Статистическую обработку данных выполняли с использованием пакета IBM-SPSS Statistics 21.  </p></sec><sec><title>Результаты</title><p>Результаты. Антиген HLA-I класса отсутствует или экспрессируется единичными опухолевыми клетками в 50,8% случаев люминального рака молочной железы. Выраженная или частичная экспрессия отмечена в 36,9% наблюдений. При Erb-B2 подтипе во всех образцах имелась экспрессия антигенов HLA-I класса. Утрата антигена HLA-I или слабая экспрессия наблюдались в 30% (3/10) случаев трижды-негативного подтипа, в таком же проценте случаев отмечена экспрессия молекул HLA-II класса. Достоверных различий в экспрессии молекул HLA между подтипами не выявлено. При помощи проточной цитометрии поражение костного мозга установлено в 40% (26/65) случаев. Не установлено значимых связей поражения костного мозга с размерами первичной опухоли, стадией, степенью злокачественности рака молочной железы, экспрессией молекул HLA. </p></sec><sec><title>Заключение</title><p>Заключение. Экспрессия молекул HLA не различалась в зависимости от биологического подтипа. Частота поражения костного мозга составила 40% и не зависела от экспрессии молекул HLA-I, -II класса. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The Implementation of immunotherapy in cancer requires a thorough analysis of the biological characteristics of the tumor. Therefore, the study of tumor immunophenotype is the leading scientific direction. Molecules of the major histocompatibility complex are considered as promising markers for evaluating the possibility of using immunotherapy. </p></sec><sec><title>Objective</title><p>Objective. To study the immunophenotype of the primary tumor in molecular subtypes of breast cancer and analyze it depending on the frequency of bone marrow damage.  </p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study included 99 patients with breast cancer. Tumor tissue and bone marrow samples were studied. Stages: T1 (51.5%), T2 (44.4%), T3 (2.0%). Metastatic involvement of lymph nodes (N+) was noted in 39.4% (n = 39) of cases. Immunophenotyping of the tumor was carried out on cryostat sections by immunofluorescence. Antibodies to HLA-I, HLA-II, KL1, FITC-labeled F(ab2) antiserum fragments (Becton Dickinson, USA) were used. The bone marrow was studied by morphological (Zeiss microscope, Axioskop, Germany) and immunological methods (flow cytometry, FACS Canto II, USA), data analysis – Kaluza Analysis v2.1 software. Used monoclonal antibodies: CD45, EPCAM (Becton Dickinson, USA). Statistical data processing was performed using the IBM-SPSS Statistics 21 package.  </p></sec><sec><title>Results</title><p>Results. The HLA-I antigen is absent or expressed by single tumor cells in 50.8% of cases of luminal breast cancer. Pronounced or partial expression was noted in 36.9% of cases. With the Erb-B2 subtype, all samples had the expression of antigens of the HLA-I class. Loss of HLA-I antigen or weak expression was observed in 30% (3/10) of cases of the triple-negative subtype, in the same percentage of cases the expression of HLA-II molecules was noted. There were no significant differences in the expression of HLA molecules between subtypes. Using flow cytometry, bone marrow involvement was detected in 40% (26/65) of cases. There were no significant relationships between bone marrow damage and the size of the primary tumor, stage, grade of breast cancer, or expression of HLA molecules.  </p></sec><sec><title>Conclusions</title><p>Conclusions. The expression of HLA molecules does not differ in significant differences depending on the biological subtype. The frequency of bone marrow damage did not depend on the expression of HLA-I, class II molecules. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рак молочной железы</kwd><kwd>иммунофенотип</kwd><kwd>HLA-I</kwd><kwd>HLA-II</kwd><kwd>костный мозг</kwd></kwd-group><kwd-group xml:lang="en"><kwd>breast cancer</kwd><kwd>immunophenotype</kwd><kwd>HLA-I</kwd><kwd>HLA-II</kwd><kwd>bone marrow</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">American Cancer Society.
