Objectives: Venous thromboembolism (VTE) is often a problematic complication in patients with gynecological cancer. Despite increasing opportunities to use direct oral anticoagulants (DOACs) to treat VTE, there are no reports on the therapeutic outcomes of DOACs in patients with gynecological cancer; however, there are some studies on cancer patients in general. We retrospectively examined the efficacy and safety of using DOACs to treat VTE in such patients.
Methods: The study cohort comprised 43 patients with gynecological cancer and VTE who received treatment between May 2005 and April 2016. They were divided into two groups: DOACs used (DOAC group, n=21) and only unfractionated heparin (UFH) and warfarin used (standard group, n=22). The rates of improvement and recurrence of VTE and incidence of adverse events were compared between these groups.
Results: At 6 months, the VTE of 85% of patients in the DOAC group and of 75% in the standard group had improved (p=0.59). No recurrences of VTE occurred in the DOAC group; where VTE recurred in 12.5% of patients in the standard group. Adverse events occurred in three patients in the DOAC group (15.3%) and one in the standard group (7.7%). Chemotherapy significantly impacted improvement in VTE (p=0.01).
Conclusions: Rates of VTE improvement and of recurrence of VTE and adverse events did not differ significantly between the study groups.
