目的 探讨肝肠钙黏连蛋白(CDH17)在结直肠癌(CRC)组织表达及其预后相关的影响因素.方法 选取2010年2月-2013年6月本院收治的CRC病人63例作为研究对象,其癌组织标本均经肠镜活检诊断且术后经病理检查确诊;随机选取其中30例病人对应的癌旁正常组织标本作为对照.采用免疫组织化学SP法检测CDH17在癌组织和癌旁正常组织标本中的表达水平,分析CDH17蛋白表达与CRC病人临床病理特征的关系以及CRC病人预后的影响因素.结果 CDH17在CRC癌组织中的阳性表达率为20.63%(13/63),在癌旁正常组织中的阳性表达率为66.67%(20/30),癌组织中CDH17的阳性表达率明显低于癌旁正常组织,差异具有统计学意义(x 2=3.935,P<0.05).CDH17蛋白表达与CRC的TNM分期、分化程度及淋巴结转移密切相关(x2=3.285~3.716,P<0.05).单因素、多因素分析显示,CRC病人的独立预后因素有TNM分期、淋巴结转移和CDH17表达阳性.结论 CDH17在CRC中呈高表达,且与TNM分期、分化程度及淋巴结转移密切相关;TNM分期、淋巴结转移以及CDH17表达阳性为CRC病人的独立预后因素.
EXPRESSION OF LIVER-INTESTINE CADHERIN IN COLORECTAL CANCER TISSUE AND ITS CLINICAL SIGNIFICANCE
Objective To investigate the expression of liver-intestine cadherin CDH17 in colorectal cancer (CRC) and its prognostic significance.Methods A total of 63 patients with CRC who were admitted to our hospital from February 2010 to June 2013 were enrolled;colonoscopic biopsy was performed for CRC tissue samples,and a confirmed diagnosis was made by pa thological examination.Corresponding normal adjacent tissue samples were collected from 30 patients,who were randomly selected from these 63 patients,and used as controls.The immunohistochemical SP method was used to measure the expression of CDH17 in CRC tissue samples and normal adjacent tissue samples.The association of the expression of CDH17 with clinicopathological fea tures of CRC patients was analyzed,and the influencing factors for the prognosis of CRC patients were identified.Results The positive expression rate of CDH17 was 20.63% (13/63) in CRC tissue samples and 66.67% (20/30) in normal adjacent tissue samples,and the CRC tissue samples had a significantly higher positive expression rate than the normal adjacent tissue samples (x2 =3.935,P <0.05).The expression of CDH 17 protein expression was closely associated with TNM stage,degree of tumor differentiation,and lymph node metastasis (x2 =3.285-3.716,P <0.05).The univariate and multivariate analyses showed that TNM stage,lymph node metastasis,and positive expression of CDH17 were independent prognostic factors for CRC patients.Conclusion CDH17 is highly expressed in CRC and is closely associated with TNM stage,degree of tumor differentiation,and lymph node metastasis.TNM stage,lymph node metastasis,and positive expression of CDH17 are independent prognostic factors for CRC patients.
