Существенным недостатком стандартного иммуногистохимического метода определения TILs является невозможность полноценной оценки субпопуляционного состава иммунного инфильтрата, в том числе его минорных популяций.Целью данного исследования было изучение субпопуляционного состава лимфоидного инфильтрата при ТН РМЖ у пациентов, получавших неоадъювантную химиотерапию (НАХТ), и его влияние на достижение полного патоморфологического ответа на лечение (pCR = RCB 0).Материалы иметоды: В исследование включено 90 пациенток с первично-операбельным (40%) и неоперабельным местнораспространенным (60%) ТН РМЖ, получавших НАХТ по схеме: АС 1 раз в 2 недели, далее 12 еженедельных введений паклитаксел 80 мг/м2 + карбоплатин AUC2. Субпопуляционный состав TILs оценивался в образцах core-биопсии до начала НАХТ у всех больных. Анализ осуществлялся методом проточной цитофлуориметрии. Проведена клинико-иммунологическая оценка по следующим девяти субпопуляциям лимфоцитов: CD3+CD4+, CD3+CD8+, CD4+CD25highCD127–/low, CD3–CD19+, CD3–CD16+CD56+, CD3+CD16+CD56+, CD4+CD25+, CD8+CD279+, CD4+CD279+.Результаты: Частота pCR составила 51,1%. Общее содержание TILs в группах с полным и неполным патоморфозом (RCB 0 против RCB I–III) статистически не различалось (р = 0,271). При анализе субпопуляционного состава для популяций CD3+CD8+, CD3–CD16+CD56+, CD3+CD16+CD56+, CD3+CD4+, CD3–CD19+, CD4+CD25+, CD4+CD25highCD127–/low и CD4+CD279+ не было выявлено статистически значимых различий между медианными значениями в группах с полным и неполным патоморфозом. При исследовании популяции CD8+CD279+ выявлен более высокий уровень данных клеток у пациентов, достигших pCR/RCB 0 (медиана 18,6% против 12,3% при RCB I–III) (р = 0,033). При уровне CD8+CD279+ выше медианы (high) частота pCR составила 61,1% против 35% в подгруппе c содержанием CD8+CD279+ менее или равно медианы (low). Несмотря на отсутствие статистически значимых различий в содержании CD3+CD16+CD56+ (NKT-клеток) в группах с полным и неполным патоморфозом (р = 0,091), были выявлены численные различия в медианах: 9,9% и 8,3% соответственно. При уровне CD3+CD16+CD56+(NKT) выше медианы (high) частота pCR составила 63% против 35,7% в подгруппе c содержанием CD3+CD16+CD56+ менее или равно медианы (low). При выделении узкой подгруппы (CD8+CD279+ high и CD3+CD16+CD56+ high) частота полных патоморфологических регрессий в ней составила 87,5% против 27,3% при низких обоих показателях.Вывод: Таким образом, исходное высокое содержание CD8+CD279+ и CD3+CD16+CD56+ в опухоли явилось предиктором высокой чувствительности к НАХТ и ассоциировалось с большей частотой полных патоморфологических ответов.</p></abstract><trans-abstract xml:lang="en"><p>Recent studies have shown that triple-negative breast cancer (TN BC) is characterized by the highest mutational load and immunogenicity compared to other subtypes, as well as the degree of tumor-infiltrating lymphocytes (TILs) infiltration, which play an important role in the development of antitumor immunity and treatment response. A significant disadvantage of the standard immunohistochemical method for determining TILs is the inability to fully assess the subpopulation structure of the immune infiltration, including minor populations.Aim: The evaluation of the subpopulations of breast cancer lymphoid infiltration in patients receiving neoadjuvant chemotherapy (NACT) and its influence on achieving a complete pathomorphological response (pCR = RCB 0).Materials and methods: The study included 90 patients who received NACT in following regimen: AC (doxorubicin 60 mg/m2  + cyclophosphamide 600 mg/m2 ) every 2 weeks, followed by 12 weekly infusions of paclitaxel 80 mg/m2  + carboplatin AUC2. The TILs subpopulations were evaluated in core-biopsy samples prior to the NACT in all patients. The analysis performed by flow cytofluorimetry. Clinical and immunological analysis was performed for the following 9 lymphocyte subpopulations: CD3+CD4+, CD3+CD8+, CD4+CD25highCD127– / low, CD3–CD19+, CD3–CD16+CD56+, CD3+CD16+CD56+, CD4+CD25+, CD8+CD279+, CD4+CD279+.Results: The frequency of pCR was 51,1 %. The total TILs content in groups with pCR and non-pCR (RCB 0 vs RCB I–III) did not differ statistically (p = 0.271). The subpopulations analysis for CD3+CD8+, CD3–CD16+CD56+, CD3+CD16+CD56+, CD3+CD4+, CD3–CD19+, CD4+CD25+, CD4+CD25highCD127– / low and CD4+CD279+ revealed no statistically significant differences between the median values in the groups with pCR and non-pCR. A study of the CD8+CD279+ population showed a higher level of these cells in patients achieved pCR / RCB 0 (median 18,6 % vs 12,3 % with RCB I–III) (p = 0.033). With CD8+CD279+ above the median (high, &gt; Me), the pCR frequency was 61 % vs 35 % in the subgroup with CD8+CD279+ less than or equal to the median (low, ≤Me). Despite the absence of statistically significant differences in the content of CD3+CD16+CD56+(NKT-cells) in groups with pCR and non-pCR (p = 0.091), numerical differences in medians were revealed: 9,9 % and 8,3 %, respectively. At the same time, with CD3+CD16+CD56+(NKT) &gt; Me (high), the pCR frequency was 63 % vs 36 % in the subgroup with CD3+CD16+CD56 + ≤Me (low). When selecting a narrow subgroup (CD8+CD279+ high and CD3+CD16+CD56+ high), the frequency of pCR was 87,5 % vs 27,3 % in the group with both low indicators.Conclusion: The high content of CD8+CD279+ and CD3+CD16+CD56+ in the tumor sample before the treatment start was a predictor of high sensitivity to NACT and is associated with a higher frequency of pCR.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак молочной железы</kwd><kwd>неоадъювантная химиотерапия</kwd><kwd>системный иммунитет</kwd><kwd>опухоль-инфильтрирующие лимфоциты</kwd><kwd>CD8+PD-1+</kwd><kwd>NKT</kwd><kwd>RCB</kwd></kwd-group><kwd-group xml:lang="en"><kwd>breast cancer</kwd><kwd>neoadjuvant chemotherapy</kwd><kwd>systemic immunity</kwd><kwd>tumor-infiltrating lymphocytes</kwd><kwd>CD8+ PD-1+</kwd><kwd>NKT</kwd><kwd>RCB</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">Sørlie T, Perou CM, Tibshirani R et al.
