【摘要】 目的探讨黏蛋白MUC1、MUC2及基质金属蛋白酶MMP-3在大肠腺瘤及大肠癌中的联合表达及其与临床各个病理参数之间的关系。方法应用免疫组织化学方法检测20例大肠腺瘤和60例大肠癌中MUC1、MUC2及MMP-3的表达。结果20例大肠腺瘤及60例大肠癌中,MUC1、MUC2、MMP-3阳性表达率分别为10%、46.7%(P=0.013);100%、58.3%(P=0.000);10%、41.7%(P=0.031)。大肠腺癌中MUC1的表达与肿瘤的分化程度呈负相关(P=0.006),与浸润深度(P=0.004)、淋巴结转移(P=0.01)、Dukes分期(P=0.033)呈正相关,与预后呈负相关。MUC2的表达与分化程度无关(P=0.143),而与浸润深度(P=0.016)、淋巴结转移(P=0.002)、Dukes分期(P=0.005)呈负相关,与生存期呈正相关。MMP-3的阳性表达与淋巴结转移(P=0.017)呈正相关,与预后呈负相关。联合检测MUC1、MUC2、MMP-3表明:MUC1与MUC2呈负相关,MUC2+MUC1-预后最好、MUC1+MUC2-预后最差。结论MUC1、MMP-3的上调表达或MUC2的下调表达可能参与了大肠癌的发生、发展、浸润及转移,对临床上判断预后具有较大的意义。更多还原

【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.更多还原
