Their cardiac toxicity is not only a life-threatening complication, but also leads to the rejection of effective chemotherapy, thereby reducing the life expectancy of patients.</p> <p><bold>Methods.</bold> A cohort of 16 patients with various types of solid gastrointestinal tumors, treated with fluoropyrimidines with detected cardiotoxicity was selected. All patients received treatment at the N.N. Blokhin National Medical Research Institute of Oncology from February 2021 to February 2022.</p> <p><bold>Results. </bold>The most common symptoms of cardiotoxicity included dyspnea, retrosternal pain, and short-term loss of consciousness. An increase in the blood troponin I and NTproBNP levels was registered in 4 patients. In 56% of patients, cardiotoxicity was noted during the first course of treatment. In 1 (6.25%) of 16 cases, a fatal outcome was registered: sudden death during the first infusion of fluorouracil (5-FU).</p> <p><bold>Conclusion. </bold>Patients treated with fluoropyrimidines should be closely monitored and 5-FU should be discontinued at the first sign of cardiovascular toxicity. Re-administration of fluoropyrimidines is not recommended unless they significantly improve the prognosis; but after careful examination of the cardiovascular system, prophylaxis under close monitoring against the background of enhanced cardiac therapy, it is worth considering switching to a bolus of 5-FU. Recognition of risk factors for fluoropyrimidine-associated cardiotoxicity even before the start of chemotherapy is necessary, since it allows either to reduce their influence or to enhance control to detect complications at an early stage.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Фторпиримидины являются высокоэффективными и часто назначаемыми противоопухолевыми препаратами, которые используются в широком диапазоне схем химиотерапии (ХТ) для лечения различных типов злокачественных новообразований. Их кардиологическая токсичность не только является жизнеугрожающим осложнением, но и приводит к отказу от эффективной ХТ, тем самым сокращая продолжительность жизни пациентов.</p> <p><bold>Методы. </bold>Была отобрана когорта пациентов из 16 человек с различными типами сóлидных опухолей желудочно-кишечного тракта, получавших лечение с включением фторпиримидинов, у которых была отмечена кардиотоксичность. Все пациенты получали лечение в НМИЦ онкологии им Н.Н. Блохина с февраля 2021 по февраль 2022 г.</p> <p><bold>Результаты. </bold>Самыми частыми симптомами кардиотоксичности были одышка, загрудинные боли, кратковременная потеря сознания. Повышение уровней тропонина I и NTproBNP в крови зарегистривано у четырех пациентов. В 56% случаев кардиотоксичность отмечена во время проведения первого курса лечения. В 1 (6,25%) из 16 случаев зарегистрирован летальный исход: внезапная смерть во время первой инфузии фторурацила (5-ФУ).</p> <p><bold>Выводы.</bold> Пациенты, получающие лечение на основе фторпиримидинов, должны находиться под пристальным наблюдением, при первых симптомах кардиоваскулярной токсичности введение 5-ФУ должно быть прекращено. Повторное введение фторпиримидинов не рекомендуется, за исключением случаев, когда они значительно улучшают прогноз, но после тщательного обследования сердечно-сосудистой системы, проведения профилактики, под тщательным мониторингом на фоне усиленной кардиологической терапии, стоит рассмотреть перевод на болюсное введение 5-ФУ. Распознавание факторов риска фторпиримидин-ассоциированной кардиотоксичности еще до начала ХТ имеет существенное значение, поскольку позволяет либо уменьшать их влияние, либо усиливать контроль для выявления осложнений на ранней стадии.</p></trans-abstract><kwd-group xml:lang="en"><kwd>fluoropyrimidines</kwd><kwd>cardiotoxicity</kwd><kwd>5-FU</kwd><kwd>gastric cancer</kwd><kwd>pancreatic cancer</kwd><kwd>colon cancer</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>фторпиримидины</kwd><kwd>кардиотоксичность</kwd><kwd>5-ФУ</kwd><kwd>рак желудка</kwd><kwd>рак поджелудочной железы</kwd><kwd>рак толстой кишки</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Luis Z.J., Lancellotti P., Munoz D.R., et al.
