Risk Assessment Models of Venous Thromboembolism for Cancer Patients and Their Applications

Venous thromboembolism (VTE) is a common complication and death cause of cancer patients. Some studies have shown that effective VTE risk assessment model and appropriate preventive anticoagulation therapy can reduce the risk of thrombosis in cancer patients. But before patients start preventive anticoagulant treatment, they need an effective VTE risk assessment model to carry out VTE risk stratification. For the high-risk group of VTE patients, preventive anticoagulation should be carried out after eliminating the contraindications of anticoagulation. However, tumor diseases have complexity, different pathological types and stages are with different risks and characteristics of VTE. The current VTE risk assessment models for cancer patients are still limited. This paper mainly reviews the current situation and application of VTE risk assessment model for cancer patients.
