Изучить механизмы, особенности клинических проявлений и возможности прогнозирования развития кардиотоксичности, возникающей в результате химиотерапии антрациклинами.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Обследованы 176 женщин с раком молочной железы, получавших антрациклиновые антибиотики в составе схем полихимиотерапевтического (ПХТ) лечения. Пациентки были разделены на 2 группы: с развитием кардиотоксического ремоделирования — группа 1 (n=52) и с сохраненной функцией сердца — группа 2 (n=124). До начала курса химиотерапии, в динамике лечения антрациклинами и после терапии таковыми проводилось эхокардиографическое (ЭхоКГ) исследование. В сыворотке крови после окончания ПХТ определяли концентрации предшественника мозгового натрийуретического пептида (NT-proBNP) и растворимого Fasлиганда (sFas-L).</p></sec><sec><title>Результаты</title><p>Результаты. Анализ ЭхоКГ-параметров у пациенток через 12 мес. после завершения ПХТ в сравнении с таковыми до начала лечения показал достоверное значимое различие конечного систолического и конечного диастолического размеров, а также достоверное снижение фракции выброса левого желудочка в 1 группе. Выявлена прямая корреляционная зависимость конечного систолического и конечного диастолического размеров и обратная взаимосвязь показателей фракции выброса левого желудочка с полученной суммарной дозой доксорубицина. У женщин 1 группы после первого курса ПХТ изменения ЭхоКГ-показателей через 12 мес. лечения регистрировались в 49% случаев, тогда как у больных 2 группы значимые изменения показателей сердца выявлены в 11% случаев. Концентрации sFas-L и NT-proBNP после завершения ПХТ в 1 группе были значимо выше по сравнению с аналогичным показателем во 2 группе. Пациентки, у которых уровень NT-proBNP был значительно повышен после окончания ПХТ, имели высокий риск развития сердечной патологии в течение 12 мес. наблюдения. Высокая концентрация NT-proBNP является предиктором сердечно-сосудистых осложнений, и данный метод диагностики является более чувствительным, чем ЭхоКГ для прогнозирования изменений со стороны сердца.</p></sec><sec><title>Заключение</title><p>Заключение. Fas-зависимый апоптоз играет важное значение в патогенезе антрациклиновой кардиотоксичности. NT-proBNP может являться важным биомаркером развития кардиотоксичности при терапии антрациклинами до появления ЭхоКГ или клинических признаков патологии.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To study the mechanisms, features of clinical manifestations and predicting of cardiotoxicity resulting from anthracycline chemotherapy.</p></sec><sec><title>Material and methods</title><p>Material and methods. We examined 176 women with breast cancer who received anthracycline antibiotics as part of polychemotherapeutic (PCT) treatment. Patients were divided into 2 groups: with the development of cardiotoxic remodeling — group 1 (n=52) and with preserved heart function — group 2 (n=124). We conducted echocardiographic (EchoCG) tests before the start, during and after anthracycline chemotherapy. In the serum after the termination of PCT treatment, the concentrations of N-terminal prohormone of brain natriuretic peptide (NT-proBNP) and soluble Fas ligand (sFas-L) were determined.</p></sec><sec><title>Results</title><p>Results. Analysis of EchoCG parameters in patients after 12 months of PCT finish, showed a significant difference in the final systolic and end diastolic sizes, as well as a significant decrease in the left ventricular ejection fraction in group 1 compared with those before the start of treatment. A direct correlation was found between the end-systolic and end-diastolic volumes and inverse correlation between left ventricular ejection fraction and the resulting summary dose of doxorubicin. EchoCG changes in women of group 1 after the first course of PCT treatment were recorded in 49% of cases and 11% of cases — in group 2. The concentrations of sFas-L and NT-proBNP after PCT therapy finish in group 1 were significantly higher compared with group 2. Patients with significantly elevated NT-proBNP levels were had a high risk of heart disease developing during 12 months follow-up. A high concentration of NT-proBNP is a predictor of cardiovascular complications, which is more sensitive than EchoCG.</p></sec><sec><title>Conclusion</title><p>Conclusion. Fas-associated apoptosis plays an important role in the pathogenesis of anthracycline cardiotoxicity. NT-proBNP may be an important biomarker for cardiotoxicity development, which already effective when EchoCG or clinical signs is absent.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>кардиомиопатия</kwd><kwd>кардиотоксичность</kwd><kwd>антрациклины</kwd><kwd>химиотерапия</kwd><kwd>биомаркеры</kwd><kwd>натрийуретические петиды</kwd><kwd>Fas-лиганд</kwd><kwd>прогноз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cardiomyopathy</kwd><kwd>cardiotoxicity</kwd><kwd>anthracyclines</kwd><kwd>chemotherapy</kwd><kwd>biomarkers</kwd><kwd>natriuretic peptides</kwd><kwd>Fas-ligand</kwd><kwd>prognosis</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">DeSantis CE, Lin CC, Mariotto AB, et al.
