Abstract:
Objective To investigate the clinicopathological significance of periostin and MMP-2 in colorectal carcinoma.Methods Immunohistochemistry was used to detect the expression of periostin and MMP-2 in colorectal carcinoma,tubular adenoma,villous adenoma and normal colorectal tissue.The correlations between the expression of periostin and MMP-2 with clinicopathologic parameters were analyzed.Results In colorectal carcinoma,tubular adenoma,villous adenoma and normal colorectal tissue,the positive rates of periostin were 83.7 ％ (41/49),40.0 ％ (6/15),32.1％ (9/28),0 (0/15),respectively,while the positive rates of MMP-2 were 71.4 ％ (35/49),60.0 ％ (9/15),64.3 ％ (18/28),0(0/15),respectively.There were significant differences among the groups (x2 =41.252,P =0.000; x2 =24.811,P =0.000).The expression of periostin in colorectal carcinoma tissue were not correlated with sex (x2 =0.002,P =0.961),age (x2 =2.267,P =0.132),tumor sites (x2 =1.506,P =0.220),differentiation status (x2 =0.875,P =0.350) and lymphatic metastasis (x2 =3.315,P =0.069).The expression of MMP-2 in colorectal carcinoma were correlated with lymphatic metastasis (x2 =5.800,P =0.016),whereas not correlated with sex (x2 =0.562,P =0.453),age (x2 =0.138,P =0.711),tumor sites (x2 =0.408,P =0.532),differentiation degree (x2 =1.335,P =0.248).The expression of periostin and MMP-2 were positively correlated in colorectal carcinoma (r =0.332,P =0.020).Conclusion Periostin and MMP-2 are correlated closely with the development and progression of colorectal carcinoma.It might be helpful for evaluating the biological properties and prognosis of colorectal carcinoma,and it would be more accurate to use a combined analysis of the two indicators.
