Objective Venous thromboembolism (VTE) is a common cancer complication. Patients with cancer have a high risk of recurrent VTE and bleeding. We analyzed the effectiveness of VTE treatment via subcutaneous fondaparinux injection for patients with and without cancer. ⋯ In addition, the quantitative evaluation of pulmonary thromboembolism (PTE) after treatment showed that PTE decreased or disappeared in 38/40 patients (95.0%) in the cancer group and 55/63 patients (87.3%) in the noncancer group, indicating no significant difference in the improvement rate between the groups. Conclusion Fondaparinux was effective for VTE both in patients with and without cancer, with no significant differences in the changes in the QUT score. However, the change in the QUT score was smaller in patients with cancer than in those without cancer, suggesting that the efficacy of fondaparinux might be diminished in patients with cancer.
