The use of direct oral anticoagulants (DOACs) has been largely -implemented in the management of venous thromboembolic disease in non-cancer patients. In cancer-associated thrombosis, low molecular weight heparins (LMWHs) and especially dalteparin have long been the reference standard therapy. Following the publication of two randomised trials comparing edoxaban and rivaroxaban to -dalteparin, DOACs now represent an alternative with an interesting efficacy and safety profile. Moreover, they offer the comfort of an oral administration and a lower cost. In patients with gastrointestinal or genitourinary cancers however, a higher bleeding risk has been shown with DOACs. LMWHs thus remain the treatment of choice in this group of patients.
