Эффективность назначения адъювантной химиотерапии по схеме АС в дозоуплотненном режиме по сравнению со стандартным режимом дозирования с последующим переходом на таксаны при люминальном раке молочной железы доказана в многочисленных клинических исследованиях и в крупном метаанализе группы EBCTCG. Однако на данный момент не опубликовано исследований, изучавших эффективность данных режимов в неоадъювантной химиотерапии (НАХТ) люминального HER2-негативного рака молочной железы.</p></sec><sec><title>Цель исследования</title><p>Цель исследования. Изучение эффективности по системе RCB дозоуплотненных режимов НАХТ ЭР + HER2– РМЖ (четыре курса АС раз в 2 недели [dose dense, ddАС], далее – четыре курса доцетаксела раз в 3 недели или 12 еженедельных введений Паклитаксела [4D/12P]) и их сравнение со стандартными (АС раз в 3 недели [ACq3w], далее – 4D/12P). Первичные конечные точки – частота полного ответа (pCR) и RCB0–I.</p></sec><sec><title>Методы</title><p>Методы. В данное ретроспективное исследование были включены пациенты с операбельным или местнораспространенным люминальным HER2-негативным раком молочной железы, получившие НАХТ с января 2017 по август 2022 года, проспективный набор пациентов в группу ddAC‑4D/12P происходил с ноября 2018 года. Статистическая гипотеза: проведение дозоуплотненного режима по схеме АС по сравнению со стандартным режимом дозирования с последующим переходом на таксаны увеличивает частоту RCB0–I с 22 до 32%; при мощности исследования 80%, ά = 0,05, необходимо включить в исследование 138 пациенток. Всего в исследование включено 315 пациенток, из них 147 получили ddAC и 168 – ACq3w. Проведена псевдорандомизация (propensity matching analysis), в результате которой в финальный анализ включено по 138 пациентов в каждую группу.</p></sec><sec><title>Результаты</title><p>Результаты. Частота полного патоморфологического ответа составила 18,8% в группе ddAC против 14,5% в группе ACq3w, различия статистически недостоверны (р = 0,379). Частота RCB0–I была достоверно выше в группе ddAC – 33,3% против 21,7% в группе ACq3w (p = 0,040). По данным подгруппового анализа, достоверное увеличение вероятности достижения RCB0–I при назначении химиотерапии по схеме ddАС наблюдалось у пациенток моложе 50 лет, cN0, экспрессией РП (рецепторов прогестерона) в ≥ 20% опухолевых ядрах.</p></sec><sec><title>Вывод</title><p>Вывод. В данном исследовании впервые проведено сравнение эффективности дозоуплотненного режима НАХТ по схеме АС со стандартным режимом ACq3w с последующим таксановым этапом люминального HER2-негативного рака молочной железы. НАХТ ddAC была достоверно ассоциирована с повышением частоты RCB0–I.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The efficacy of dose-dense AC in adjuvant chemotherapy of luminal breast cancer (ER+ BC) compared with the standard dosing regimen followed by switching to taxanes has been proven in numerous clinical trials and in a large meta-analysis of the EBCTCG group. However, no study about efficiency of this regimen in neoadjuvant setting has been published.</p></sec><sec><title>The aim of the study</title><p>The aim of the study. To assess the effectiveness of dose-dense regimens of neoadjuvant chemotherapy (NAC) of ER + HER2-BC (4 AC once every 2 weeks (dose dense, ddAC), then 4 courses of Docetaxel once every 3 weeks or 12 weekly injections of Paclitaxel [4D/12P]) and their comparison with the standard ones (AC once every 3 weeks [ACq3w], hereinafter 4D/12P). Primary end points are complete response rate (pCR) and RCB0–I.</p></sec><sec><title>Methods</title><p>Methods. This retrospective study included patients with resectable or locally advanced luminal HER2-negative breast cancer who received NAC from Janu 2017 to Aug 2022. Statistical hypothesis – the dose-dense regimen AC increases the frequency of RCB0–I from 22 to 32% compared to the standard dosing regimen with subsequent switching to taxanes, with a study power of 80%, ά = 0.05, 138 patients should be included in the study. A total of 315 patients were included in the study, of which 147 and 168 patients received dose-dense (ddAC) and standard chemotherapy (ACq3w), respectively. After propensity matching analysis 138 patients in each group were included in the final analysis.</p></sec><sec><title>Results</title><p>Results. The pCR rate was 18.84% in the ddAC group versus 14.49% in the AC q3w group, the differences were not statistically significant (p = 0.379). The frequency of RCB0–I was higher in the ddAC – group 33.33% versus 21.74% in the AC q3w (p = 0.040). According to the subgroup analysis, rate of RCB0–I was significantly higher in patients younger 50 years, cN0, with the expression of progesterone receptors in ≥ 20%.</p></sec><sec><title>Conclusions</title><p>Conclusions. This is the first study to compare the efficacy of a ddAC NAC with a standard regimen for ER + HER2-BC. NAC with ddAC is associated with an increase in RCB0–I rate.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>неоадъювантная химиотерапия</kwd><kwd>люминальный рак молочной железы</kwd><kwd>дозоуплотненные режимы химиотерапии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>neoadjuvant chemotherapy</kwd><kwd>luminal breast cancer</kwd><kwd>dose-dense chemotherapy</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">Seer.cancer.gov/statfacts/html/breast-subtypes.html.
