По нашим данным, даже в популяции пациенток, «обогащенной» местнораспространенными неоперабельными опухолями (T4 или N 2–3), применение режима TCHP обеспечивает более 60 % pCR. По данным рандомизированного клинического исследования (РКИ) 3 фазы KATHERINE в случае обнаружения резидуальной опухоли любого размера (RCB I, II и III) проведение постнеоадъювантной терапии трастузумабом эмтанзином (T-DM1) достоверно улучшает выживаемость. Однако в РФ показанием для назначения адъювантной терапии (АТ) T-DM1 является только RCB II и III, в то время как при RCB I (минимальная остаточная опухоль) рекомендовано проведение АТ трастузумабом, входящим в схему НАХТТ. Для оценки реальной клинической практики в Российской Федерации и выявления динамики предпочтений врачей в назначении адъювантной таргетной терапии было проведено уже третье последовательное (2021 г., 2023 г. и 2025 г.) исследование-опрос «Терапия HER2-положительного рака молочной железы», включающее в том числе вопросы, посвященные постнеоадъювантному этапу. В опросе приняли участие 50 специалистов-онкологов из 6 регионов страны (Центр, Северо-Запад, Сибирь/Дальний Восток, Юг, Урал, Волга), которые либо самостоятельно, либо в составе Консилиума назначают лечение пациентам с диагнозом HER2-позитивный РМЖ. В данной публикации отражены результаты оценки предпочтений специалистов при назначении адъювантной и постнеоадъювантной терапии. В 2025 году НАХТТ была назначена/запланирована только 75 % пациенток с ранним (M0) HER2+ РМЖ, что несколько ниже по сравнению с предыдущими опросами. Частота достижения pCR после НАХТТ, по мнению опрошенных, составила 49 %, еще в 23 % случаев зарегистрировано RCB I, в 2 % случаев оценка патоморфологического ответа не проводилась. Таким образом, процент пациентов с умеренной и выраженной остаточной опухолью (RCB II–II) после проведения НАХТТ в 2025 г. значительно уменьшился и составил всего 26 % по сравнению с 35 % в 2023 г. и 73 % в 2021 г.. Подавляющее число пациенток с RCB II–II (88 %) в 2025 г. получали постнеоадъювантную АТ T-DM1 по сравнению с 68 % в 2023 г. и 24 % в 2021 г. Кроме того, иногда T-DM1 назначался в РКП в РФ также и при RCB I. При анализе выполнения плана постнеоадъювантной терапии T-DM1 отмечена высокая приверженность пациенток и хорошая переносимость препарата: полный курс из 14 циклов завершили 82,2 %, от 7 до 13 циклов получили еще 17,4 %. В целом при выборе программы лекарственного лечения раннего первично-операбельного и местнорастространенного неоперабельного HER2-позитивного РМЖ в РФ приоритетом является эффективность и безопасность терапии. Значение проблемы доступности препаратов неуклонно снижается.</p></abstract><trans-abstract xml:lang="en"><p>Neoadjuvant chemotargeted therapy for HER2 positive breast cancer, incorporating two monoclonal antibodies (trastuzumab and pertuzumab), enables achieving the maximum rate of pathologic complete responses (pCR), which significantly improves the prognosis and long term treatment outcomes. According to our data, even in a patient population “enriched” with locally advanced inoperable tumours (T4 or N 2–3), the use of the TCHP regimen ensures a pCR rate exceeding 60 %. Based on the findings of the phase 3 randomized clinical trial KATHERINE, in cases where residual tumour of any size is detected (RCB I, II, and III), administration of post neoadjuvant therapy with trastuzumab emtansine (T-DM1) significantly improves survival. However, in the Russian Federation, the indication for adjuvant therapy with T-DM1 is limited to RCB II and III only. In contrast, for RCB I (minimal residual tumour), adjuvant therapy with trastuzumab – which is part of the NACHTT regimen – is recommended. To assess real-world clinical practice in the Russian Federation and identify trends in physicians’ preferences for adjuvant targeted therapy, the third consecutive survey study “Therapy for HER2-Positive Breast Cancer” (conducted in 2021, 2023, and 2025) was carried out. The survey included questions addressing the post-neoadjuvant phase. Fifty oncology specialists from six regions of the country (Central, Northwestern, Siberia/Far East, Southern, Ural, and Volga regions) participated in the survey. These specialists either independently or as part of a tumor board prescribe treatment for patients diagnosed with HER2-positive breast cancer. This publication presents the results of assessing specialists’ preferences in prescribing adjuvant and post-neoadjuvant therapy. In 2025, neoadjuvant chemotargeted therapy (NACTT) was prescribed/planned for only 75 % of patients with early-stage (M0) HER2+ BC, which is slightly lower compared to previous surveys. According to the respondents, the pCR rate after NACHTT was 49 %; RCB I was reported in another 23 % of cases, while pathological response assessment was not performed in 2 % of cases. Thus, the proportion of patients with moderate to severe residual tumour (RCB II–III) after NACHTT significantly decreased in 2025, reaching only 26 %, compared to 35 % in 2023. The vast majority of patients with RCB II–III (88 %) received post-neoadjuvant T-DM1 adjuvant therapy in 2025, compared to 68 % in 2023 and 24 % in 2021. Additionally, T-DM1 was occasionally prescribed in the Russian clinical practice for RCB I cases as well. Analyzing adherence to the post-neoadjuvant T-DM1 therapy plan, high patient compliance and good drug tolerability were noted: 82.2 % completed the full course of 14 cycles, while another 17.4 % received 7 to 13 cycles. Overall, when selecting a drug treatment regimen for early operable and locally advanced inoperable HER2-positive BC in the Russian Federation, the priority is given to therapy efficacy and safety. The significance of the issue of drug availability is steadily decreasing.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>HER2-позитивный рак молочной железы</kwd><kwd>пертузумаб</kwd><kwd>трастузумаб</kwd><kwd>трастузумаб эмтанзин</kwd><kwd>T-DM1</kwd><kwd>адъювантая терапия</kwd><kwd>постнеоадъювантная терапия</kwd><kwd>предпочтения специалистов</kwd><kwd>российская клиническая практика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>HER2-positive breast cancer</kwd><kwd>pertuzumab</kwd><kwd>trastuzumab</kwd><kwd>trastuzumab emtansine</kwd><kwd>T-DM1</kwd><kwd>adjuvant therapy</kwd><kwd>post-neoadjuvant therapy</kwd><kwd>specialists’ preferences</kwd><kwd>Russian clinical practice</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">International Agency for Research on Cancer.
