Factor Xa Inhibition for the Treatment of Venous Thromboembolism Associated With Cancer: A Meta-Analysis of the Randomised Controlled Trials

Abstract

Background: Venous thromboembolism (VTE) is a common cause of morbidity and mortality in cancer patients. Until recently, guidelines recommended the use of low-molecular weight heparin (LMWH) as standard of care for VTE in patients with cancer. Despite the proven efficacy of direct oral anticoagulants (DOACs) for treatment of VTE, there is equipoise supporting their use in cancer patients. Methods: A systematic review of PubMed, Medline and EMBASE identified four randomised controlled trials (RCTs) in patients with cancer and VTE comparing a factor Xa inhibitor (FXaI) to LMWH. A meta-analysis was performed with a primary outcome of VTE recurrence and key secondary outcomes of major bleeding,..
