BackgroundCancer-associated thromboembolism (CAT) is usually managed with low-molecular-weight heparins (LMWHs) or vitamin K antagonists (VKAs). The recent data suggest that direct-acting oral anticoagulants (DOACs) might have a role in the management of CAT both in terms of prevention and treatment. The aim of this article is to review the current literature regarding the use of DOACs in patients with cancer.MethodsPUBMED and ClinicalTrials.gov were searched to identify prospective trials on patients with cancer managed with DOACs as either primary prophylaxis or treatment of venous thromboembolic events.ResultsIn terms of primary prophylaxis, five studies (CASSINI, ADVOCATE, MYELAXAT, NCT02958969, and AVERT) have been identified.
