Abstract
Introduction Cancer patients face a venous thromboembolism (VTE) risk that is up to 50 times higher compared to individuals without cancer. In 2010, direct oral anticoagulants (DOACs) such as apixaban, rivaroxaban, and edoxaban were introduced, consequently becoming the controversial oral anticoagulants for VTE therapy. This study is a meta-analysis of randomized clinical trials (RCTs) evaluating the use of edoxaban for treating VTE in cancer patients over different treatment durations. Methods Using Google Scholar, a systematic search for RCTs on edoxaban for cancer-associated VTE was performed. The data extracted covered patient numbers, age, gender, BMI, cancer type, edoxaban dosage, treatment duration, comorbidities, major bleeding, recurrent VTE incidence, and deaths. Statistical significance was set at 0.05. Results Out of 52 studies, nine with 3,190 cases met the inclusion criteria. The mean age was 66.68 years, with 1,604 females (50.28%). Major bleeding occurred in 192 patients (7.66%) in the 6- or 12-month group and 57 (8.35%) in the 3-month group (p=0.573). Recurrent VTE was observed in 145 patients (5.78%) in the 6- or 12-month group and 95 (13.91%) in the 3-month group (p<0.001). Deaths from any cause totaled 548 (21.86%) in the 6- or 12-month group and 165 (24.16%) in the 3-month group (p=0.110). Conclusion Cancer patients receiving edoxaban for six or 12 months experience a lower recurrence rate of VTE compared to those on a 3-month treatment. The incidence of major bleeding appears to be similar between the two treatment durations.
