Opinion statement
Cancer patients are at high risk for venous thromboembolism (VTE) which is considered the second leading cause of death among this population. Both cancer and cancer treatment increase this risk. Since the risk of VTE is not the same in all cancer patients, it is important to understand what factors increase the risk of incident and the risk of recurrent VTE in this patient population. In an effort to combine multiple factors into a single risk stratification system, a scoring system for recurrent VTE risk in cancer patients has been developed and externally validated. While vitamin K antagonists (VKA) or the direct oral anticoagulants (DOACs) are first-line therapies for non-cancer-associated VTE treatment, low-molecular-weight heparin (LMWH) agents are the first-line anticoagulant for treatment of cancer-associated VTE. In this review, we discuss the epidemiology, pathophysiology, and risk stratification used in cancer-associated VTE. We also discuss the current therapies for cancer-associated VTE and the evidence supporting their use from the literature.

The trial also demonstrates no increased risk of bleeding for the LMWH-treated group as compared to the warfarin-treated group.

JAMA. 2015;314(7):677–86. doi:10.1001/jama.2015.9243. This randomized trial demonstrates that LMWH is at least as good as warfarin for the prevention of VTE-recurrence in cancer patients. As compared to the earlier CLOT trial, this trial included more diverse enrollment sites and found a lower rate of VTE recurrence in both treatment groups.

Thromb Res. 2014;134(6):1214–9. doi:10.1016/j.thromres.2014.09.039. This systematic review demonstrates the superiority of LMWH over warfarin for prevention of VTE recurrence in cancer patients. It also notes that DOAC therapy cannot be recommended over LMWH until head-to-head studies are performed.

This network meta-analysis suggests that LMWH and DOACs may have similar efficacy and safety for the treatment of cancer-associated VTE. However, only indirect comparisons were made in this analysis, limiting the confidence of its conclusions.
