Updates in the Incidence, Pathogenesis, and Management of Cancer and Venous Thromboembolism

Abstract

Patients with cancer are at higher risk of developing venous thromboembolism (VTE) compared with the general population. This elevated risk is due to several risk factors and multiple, overlapping thrombotic and hemostatic pathophysiological pathways that are specific to this patient population. Hence, the management of cancer-associated VTE can be challenging for clinicians. Patients with cancer-associated VTE are at higher risk of both recurrent events despite anticoagulation and bleeding complications due to the anticoagulant regimens. Direct oral anticoagulants have recently been shown to be effective, safe, and more convenient than parenteral low-molecular-weight heparin for the management of cancer-associated VTE. Despite these recent advances in anticoagulant therapy, many unmet needs remain in these patients (increased risk of bleeding with specific cancer types, drug-drug interactions, liver dysfunction). Factor XI inhibitors are currently being assessed for the management of cancer-associated VTE and may help clinicians address these important knowledge gaps.
