Abstract

This paper aims to provide a narrative review of the risks, diagnosis, and management of recurrent venous thromboembolism (VTE) in cancer patients. There is an established association between cancer and VTE, with cancer being a major risk factor for VTE. A history of VTE, short duration of oral anticoagulation, and a proximal DVT are all associated with increased risk for recurrent VTE. Studies have shown that certain cancers (e.g., metastatic genitourinary, lung, and colorectal cancers) are associated with recurrent VTE. Published literature shows that cancer is prothrombotic, and various mechanisms have been postulated as pathways for increased thrombogenesis and hence recurrent VTE in cancer. The symptoms, signs, laboratory information, and imaging results for the diagnosis of recurrent VTE are similar to those of an initial VTE. Management of recurrent VTE involves using low molecular weight heparin (LMWH) or a direct oral anticoagulant (DOAC). Vitamin K antagonists (VKA) or inferior vena cava (IVC) filters are less commonly used.

Keywords: Cancer; Cancer-associated thrombosis; Direct oral anticoagulants; Low molecular weight heparin; Recurrent venous thromboembolism; Vitamin K antagonist.
