sentence: High expression by tumor cells is strongly correlated with high expression of VEGF receptors ( VEGFR ) -2 and VEGFR-3 by the same cells , suggesting the presence of an autocrine loop that induces epithelial proliferation.Further , in the present study with the P = 0.0032 and 0.002 significant differences were observed in the epithelium and connective tissue when VEGF expression was inter-compared between KCOT and DC. Moderate to strong expression was observed in the majority of cases of KCOT ( 92.3 % ) , on the other hand , 66.7 % cases of DC revealed moderate to strong expression .
