【摘要】 目的探讨COX-2、CCR7表达与大肠癌组织病理分化、浸润深度、淋巴转移等临床病理学参数的关系,并分析COX-2、CCR7表达的相关性。方法采用免疫组织化学方法对大肠癌组织80例、大肠癌癌周组织40例石蜡包埋切片进行染色,检测COX-2、CCR7的表达,分析其在大肠癌组织的表达与临床病理学参数的关系,对COX-2、CCR7的表达进行相关性分析。结果在大肠癌组织,COX-2、CCR7均高表达,表达率分别为72.5%和67.5%,二者表达呈正相关(P＜0.05)。COX-2、CCR7的表达均与肿瘤的浸润深度、TNM分期、淋巴转移、肿瘤大小相关(P＜0.05),与大肠癌患者的诊断年龄、性别等因素无关(P＞0.05)。CCR7的表达与肿瘤的病理分化、肿瘤部位相关,但COX-2的表达与此无关。结论COX-2、CCR7在大肠癌组织高表达,二者表达呈正相关。COX-2、CCR7的表达与大肠癌的浸润深度、TNM分期、淋巴转移、肿瘤大小等临床病理学参数有关。更多还原

【Abstract】 Objective This study was designed to evaluate the expression of COX-2 and CCR7 in human colorectal cancer and determine their relationships and correlations with lymph node metastasis,tumor differentiation,invasion depth,lymphatic metastasis and other clinicopathologic parameters.Methods Tissue samples of primary tumors from 80 colorectal cancer patients and normal colorectal tissue adjacent to cancer from 40 colorectal cancer patients,undergoing paraffin imbedding slices were immunohistochemically examined for COX-2 and CCR7 expressions.Results COX-2 and CCR7 were highly expressed in colorectal cancer tissues,the positive rate of COX-2 and CCR7 in the primary tumor was 72.5%and 67.5%,respectively.A significant correlation was found between the expression scores of COX-2 and CCR7(P＜0.05),and both also were correlated with several clinicopathologic parameters, including invasion depth,lymph node metastasis,TNM stage and primary tumor size(P＜0.05),but both were not related to patients’age, sex and other factors(P＞0.05).In addition,only CCR7 expression was associated with histology and tumor site(P＜0.05).Conclusions High expression of COX-2 and CCR7 in human colorectal cancer was a significantly correlated.COX-2 and CCR7 were significantly associated with clinicopathologic parameters,including invasion depth,lymph node metastasis,TNM stage and primary tumor size.This indicates that detection of COX-2 and CCR7 will be helpful to predicting clincally the metastasis of colorectal cancer.更多还原
