In patients with cancer who develop venous thromboembolism (VTE), guidelines now recommend direct-acting oral anticoagulants (DOACs) over low-molecular-weight heparin (LMWH) due to better efficacy and safety. In a real-world retrospective cohort of 5100 insured patients with various types of cancers (60% with metastatic disease), half received DOACs, one quarter received LMWH, and one quarter received warfarin. Median treatment duration was approximately 3 months.
In propensity-score–weighted analysis, VTE recurrence was significantly less likely in patients who received DOACs than in those who received warfarin or LMWH (20 vs. 30 and 40 VTEs per 100 person-years, respectively). Mortality was significantly lower in DOAC recipients than in LM…
