Compared to non-cancer patients who underwent similar surgery
The risk of VTE in cancer patients is 4-6 times higher than in non-cancer patients
Patients receiving chemotherapy had a 6.5 fold increased risk of VTE
The risk of DVT in cancer patients after surgery more than doubled
The risk of fatal postoperative PE in cancer patients increased more than threefold
Tumor associated with VTE leads to a significant increase in mortality. VTE is the second leading cause of death in tumor patients, second only to tumor patients with VTE due to tumor death, and the 1-year survival rate is only 1/3 of that of tumor patients without thromboembolism.
