ABSTRACT

OBJECTIVE To investigate the expression of Cyclooxygenase-2(COX-2)andVascular endothelial growth factor(VEGF)in laryngeal carcinoma tissue and its clinical significance. METHODS Sixty-five samples of laryngeal carcinoma and thirty-four biopsies of adjacent noncancerous tissue were immunohistochemically examined for expression of COX-2 and VEGF, whose relationship with clinicopathological parameters was also analysied. RESULTS Percentages of COX-2 and VEGF expression in laryngeal carcinoma tissue were 63.08% and 70.77% respectively, which were higher than those in adjacent noncancerous tissue(P
