Abstract: Purpose: To explore the relationship between Fas/FasL expression in squamous cell carcinoma, basal cell carcinoma or cell apoptosi. Methods: Fas/FasL expression and cell apoptosis were studied in 45 patients suffering from squamous cell carcinoma or basal cell carcinoma by immunohistochemistry and terminal deoxynucleotidyl transferase-mediated dUTP-DIG nick end labeling (TUNEL). Results: Fas/FasL expression in squamous cell carcinoma was higher than in basal cell carcinoma. The apoptosis rate of Fas/FasL positive cells was higher than that of Fas/FasL negative cells. Conclusion: Fas/FasL system was rather associated with cell apoptosis and may play an important role in tumor invasion.

Key words: squamous cell carcinoma, basal cell carcinoma, apoptosis, Fas/FasL
