Background And Objectives:
Tissue factor (TF), which normally safeguards vascular integrity by inducing hemostasis upon injury, has received widespread attention in the pathogenesis of cancer progression and metastasis. Aberrantly expressed TF in cancer cells has been reported to be associated with advanced stages of malignancy in various cancers.
Methods:
The expression of TF and microvessel density (MVD) were immunohistochemically evaluated in 207 gastric cancers, and their relationship with clinicopathological features was examined.
Results:
TF was preferentially expressed (41.8%) in intestinal-type cancer at a significantly higher rate than that in diffuse-type cancer (12.1%, P<0.0001). The expression of TF was associated with advanced stage of disease and showed a positive correlation with a higher rate of lymphatic and venous invasion and lymphatic metastasis in intestinal-type, but not in diffuse-type carcinoma. Moreover, TF expression was associated with high MVD in the tumor and a worse outcome only in intestinal-type carcinoma.
Conclusions:
TF may be critically involved in tumor progression in intestinal-type, but not in diffuse-type, gastric carcinoma. The difference in clinical features between these two histological types might be partially dependent on TF expression profile.
