Abstract:
Objective To explore the relationship between the associated expression of mucin MUC1、MUC2、Matrix Metalloproteinase(MMP-3)and clinicopathological parameters in colorectal adenoma and colorectal carcinoma.Methods The expression of MUC1、MUC2 and MMP-3 were detected in 20 colorectal adenomas and 60 colorectal carcinomas by immunohistochemical method.Results The positive expression rates of MUC1 、MUC2 and MMP-3 in 20 colorectal adenomas and 60 colorectal carcinomas were 10% 、46.7%(P=0.013);100%、58.3%(P=0.000);10%、41.7%(P=0.031)respectively.The expression of mucin MUC1 was negative correlated to the degree of differentiation(P=0.006),but positively correlated to the depth of invasion(P=0.004),lymph node metastasis(P=0.010),Dukes staging(P=0.033)and negafively correlated with proghosis.Mucin MUC2 expression was unrelated to differentiation(P=0.143),but negative correlated to the depth of invasion(P=0.016),lymph node metastasis(P=0.002).Dukes staging(P=0.005)and posifively correlated with survival period.The positive expression of MMP-3 was positively correlated to lymph node metastasis(P=0.002),but negatively correlated to prognosis.Associated detection of MUC1 、MUC2 and MMP-3 showed that MUC1 was negatively correlated to MUC2,MUC2+MUC1-gave the best prognosis,while MUC1+MUC2-gave the worst prognosis.Conclusions The up-regulation of MUC1、MMP-3 expression or down-regulation of MUC2 expression may be involved in carcinogenesis,progression,invasion and metastasis.And it is very important to predict the prognosis in colorectal carcinomas.
