The presence of distant metastases of solid tumors increases the risk of VTE. Most often, VTE develops in pancreatic and stomach cancers. Chemotherapy increases the risk of VTE development. Low-molecular-weight heparin and direct oral anticoagulants are used for the treatment of VTE in patients receiving chemotherapy.</p><p>Prior to the start of chemotherapy, it is necessary to assess the risk of VTE development using the Khorana risk score. Outpatient patients with high-risk cancer (Khorana score <underline>&gt;</underline>3 before the start of a new systemic chemotherapy regimen) may be prescribed thromboprophylaxis.</p></abstract><trans-abstract xml:lang="ru"><p>У пациентов со злокачественными новообразованиями частота возникновения симптомных венозных тромбоэмболических осложнений (ВТЭО) в 4–7 раз выше, чем в общей популяции. Наличие отдаленных метастазов при солидных опухолях повышает риск венозных тромбозов. Наиболее часто ВТЭО развиваются при раке поджелудочной железы и раке желудка. Химиотерапия увеличивает риск развития ВТЭО. Для их лечения при проведении химиотерапии используют низкомолекулярные гепарины и прямые оральные антикоагулянты. Перед началом химиотерапии необходимо оценить риск развития ВТЭО, используя шкалу Khorana. Амбулаторным пациентам с раком высокого риска (сумма баллов по шкале Khorana ≥3 до начала нового режима системной химиотерапии) может быть назначена профилактика ВТЭО.</p></trans-abstract><kwd-group xml:lang="en"><kwd>cancer-associated thrombosis</kwd><kwd>venous thromboembolism</kwd><kwd>direct oral anticoagulant</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>канцер-ассоциированный тромбоз</kwd><kwd>венозное тромбоэмболическое осложнение</kwd><kwd>прямой оральный антикоагулянт</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Khorana A.A., Dalal M., Lin J., Connolly G.C.
