Research Progress of Risk Assessment Models for Cancer-associated Venous Thromboembolism
Cancer is a key risk factor for venous thromboembolic events.The risk of VTE in tumor patients is 4 to 7 times that of non-tumor patients,which is the second cause of death after tumor progression or recurrence in cancer patients.Cancer associated thromboembolism results in delays or discontinuation of anti-cancer treatment and increased mortality.At present,clinical practice guidelines at home and abroad recommend risk assessment of venous thromboembolic events for cancer pa-tients.In this review,the risk assessment models were summarize for cancer-associated venous thromboembolism.
