An Update in Anticoagulant Therapy for Patients with Cancer-Associated Venous Thromboembolism.

Abstract

This review aims to assess the treatment options for cancer-associated venous thromboembolism (VTE) based on the most robust level of evidence recommendations and suggestions based on expert opinion. Several classes of anticoagulants have been studied in the treatment of cancer-associated thrombosis (CAT). Since the CLOT trial, guidelines recommend the use of low-molecular-weight heparin (LMWH) for the treatment of this condition. However, since 2018, some direct oral anticoagulants became an alternative first-line treatment for CAT. Three Xa antagonists (rivaroxaban, apixaban, and edoxaban) proved to be at least as effective as the LMWH strategy for the short-term prevention of VTE recurrence. The right choice of treatment in the context of anticoagulation strategy, thrombo-hemorrhagic risk management, and a patient's comorbidities represents a challenge. The correct management of CAT and a more individualized approach are needed to identify risk factors and offer the best treatment for each patient.
