Cancer patients with blood clots gain no benefit from inferior vena cava filter (IVCF) placement to the anticoagulant medication fondaparinux, finds research.

In the study, sixty-four patients with deep venous thrombosis (86%) and/or pulmonary embolism (55%) received fondaparinux. About half of patients received only fondaparinux, while the other half received fondaparinux in conjunction with an IVCF.
The median survival for patients receiving only fondaparinux was 493 days, compared with 266 days for patients on fondaparinux plus an IVCF. Meanwhile, a median 52% of patients on fondaparinux alone experienced a complete resolution of VTEs, compared with 45% of patients on fondaparinux plus IVCF.
The study suggests that there is no benefit from costly and invasive IVCF placement in patients who are receiving fondaparinux. The results also support future randomized trials to compare VTE resolution rates achieved with fondaparinux with low molecular weight heparin, another class of anticoagulant medication.
