【摘要】 目的:探讨CD15s和E?钙黏蛋白(E?cadherin)在肝细胞癌组织中的表达及其与肿瘤侵袭转移和患者预后的关系。方法:应用免疫组织化学方法,检测120例肝细胞癌组织中CD15s和E?cadherin蛋白表达,结合随访资料进行分析。结果:CD15s和E?cadherin在肝细胞癌中阳性表达率分别为39.2%和44.2%。CD15s阳性表达的肝细胞癌转移率高(P<0.05),分化程度及患者5年生存率低 (P<0.05);E?cadherin阳性表达的肝细胞癌转移率低(P<0.05),分化程度及患者5年生存率高(P<0.05)。 CD15s表达与E?cadherin表达呈显著负相关(P<0.05)。结论:CD15s和E?cadherin表达与肝细胞癌转移和患者生存期密切相关,联合检测CD15s和E?cadherin蛋白表达可作为判断肝细胞癌预后有价值的参考指标。

_qEXY 细胞与细胞或细胞与基质之间黏附特性的异常是恶性肿瘤细胞重要的生物学特征之一,在侵袭和转移过程中发挥了重要作用。CD15s(sialyl lewis X)和E?钙黏蛋白(E?cadherin)是近年发现的与肿瘤恶性发展密切相关的黏附分子[1?5]。我们采用免疫组化催化信号放大(catalyzed signal amplification,CSA)法,检测肝细胞癌组织中CD15s和E?cadherin蛋白表达状况,探讨它们之间的相关性,并结合临床随访资料,分析其表达与肝细胞癌侵袭转移和患者预后的关系。
