Abstract:
Background:In recent years,the incidence and mortality of colorectal carcinoma have been increasing rapidly. Diagnosing and treating cancer at gene level have become a new effective approach. Aims:To investigate the expression of S-phase kinase-associated protein 2(Skp2)and its relationship with vascular endothelial growth factor(VEGF)and tumor microvessel density(MVD)in colorectal carcinoma. Methods:Thirty-five colorectal carcinoma patients from March 2014 to March 2015 at People’s Hospital of Hubei University of Medicine were enrolled. Fifteen para-cancerous tissue samples were served as controls. The expressions of Skp2,VEGF and MVD value were determined by immunohistochemical SP, and their relationships with clinicopathological characteristics were analyzed. Results:The expression of Skp2 in colorectal carcinoma was significantly higher than that in para-cancerous tissue( P = 0. 000),and was correlated with tumor differentiation and lymph node metastasis(P < 0. 05),but not with gender,age and TNM stage(P > 0. 05). Expression of VEGF and MVD value were significantly higher than those in para-cancerous tissue(P = 0. 019,P = 0. 002),and were correlated with lymph node metastasis and TNM stage(P < 0. 05). Expression of Skp2 was positively correlated with the expression of VEGF and MVD value in colorectal carcinoma( r = 0. 569,P = 0. 000;r = 0. 481,P = 0. 017 ). Conclusions:The abnormal high expression of Skp2 is involved in the angiogenesis of colorectal carcinoma. Skp2,VEGF expressions and MVD value may be served as important markers for malignancy degree of colorectal carcinoma.
