Prevention and treatment of venous thromboembolism in cancer patients

Deep vein thrombosis and pulmonary artery embolism are common and serious concomitant diseases in patients with cancer. The prophylaxis and therapy of such venous thromboembolic events (VTE) in oncology have so far been achieved with low-molecular-weight heparins. An increasing number of studies show evidence of the use of direct oral anticoagulants. However, since none of the possible options were shown to have a clear advantage in all patients, the individual decision to use a drug should be made depending on its effectiveness in preventing VTE, the risk of bleeding, the nature of the cancer, the interactions with other medications, the route of administration, and finally the cost of treatment.
