Thrombosis in an oncological patient increases the risk of death by 30 times, which is associated with fatal thromboembolism and a more aggressive course of the disease. The leading role in the pathogenesis of thrombotic complications is played by disorders in the hemostasis system caused both by the tumor itself and by therapy. Low molecular weight heparins are considered the basis for specific prophylaxis of thromboembolic complications in cancer patients. The use of low molecular weight heparins after surgery and during chemotherapy effectively reduces the incidence of venous thrombosis. Direct oral anticoagulants are promising drugs for oral administration and are indicated as one of the treatment options for patients with tumor-associated thrombosis with a low risk of bleeding and no drug interactions with ongoing systemic chemotherapy.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель обзора</bold> – осветить современные возможности профилактики и лечения венозных тромботических осложнений у пациентов с онкологическим заболеванием.</p><p>Рассмотрены данные 52 научных источников, опубликованных в российской и зарубежной печати в 1997–2020 гг.</p><p>Онкологические больные подвержены высокому риску тромботических осложнений, которые ухудшают исходы противоопухолевого лечения и занимают одно из лидирующих мест среди причин смерти. Тромбоз у онкологического пациента увеличивает риск смерти в 30 раз, что связано с развитием смертельной тромбоэмболии и более агрессивным течением опухолевого процесса. Ведущую роль в патогенезе тромботических осложнений играют нарушения в системе гемостаза, вызываемые как непосредственно опухолью, так и методами лечения. Основой специфической профилактики тромбоэмболических осложнений у онкологических больных считают низкомолекулярные гепарины. Применение низкомолекулярных гепаринов после операции и на фоне химиотерапии эффективно снижает частоту венозных тромбозов. Прямые оральные антикоагулянты являются перспективными препарата‑ ми для приема внутрь и показаны в качестве одного из вариантов терапии пациентов с опухоль-ассоциированными тромбозами при низком риске кровотечения и отсутствии лекарственных взаимодействий с проводимой системной химиотерапией.</p></trans-abstract><kwd-group xml:lang="en"><kwd>cancer patient</kwd><kwd>thrombotic complication</kwd><kwd>low molecular weight heparin</kwd><kwd>direct oral anticoagulant</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>онкологический больной</kwd><kwd>тромботическое осложнение</kwd><kwd>низкомолекулярный гепарин</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>Agnelli G., Verso M.
