Clinical Study

The Incidence and Predictors of Thromboembolic Events in Patients with Lung Cancer

Table 1

Prothrombotic mechanisms in tumors.

Proaggregation and procoagulant activity, increased platelet
Acceleration of thrombin production, overproduction of tissue 
Factor, and other procoagulant factors
Cytokine production by tumor cells, production of TNF-1, 
interleukin-11, and VEGF
Direct interactions between tumor cells and the endothelium of 
blood vessels (increased adhesiveness)
Factors related to cancer treatment—surgery, radiotherapy, 
chemotherapy, and antiangiogenic treatment
Increased immobilization, central venous catheters
