摘要 目的探讨E-钙黏素(E-cadherin)和骨桥蛋白(osteopontin,OPN)在宫颈癌中的表达及意义。方法采用免疫组化链霉菌抗生物素蛋白-过氧化物酶连结法(SP)检测78例宫颈癌、40例宫颈上皮内瘤变(cervical intraepithelial neoplasia,CIN)、30例正常宫颈组织中E-cadherin和OPN的表达水平,并分析二者的表达与宫颈癌临床病理特征的关系。结果 E-cadherin在宫颈癌(48.7%,38/78)、CIN(60%,24/40)中的阳性表达率明显低于正常宫颈组织(100%,30/30)的表达(P均<0.05),但宫颈癌组与CIN组比较,差异无统计学意义(P>0.05)。OPN在正常宫颈组织、CIN和宫颈癌中的阳性表达率分别为13.3%(4/30)、55%(22/40)和86.7%(65/75),宫颈癌组与正常宫颈组和CIN组比较,差异均有统计学意义(P均<0.05),CIN组与正常宫颈组比较,差异有统计学意义(P<0.05)。E-cadherin的阳性表达率与宫颈癌患者的临床分期、病理分级及淋巴结转移有关(P<0.05)。OPN的阳性表达率与病理分级及淋巴结转移有关(P<0.05),与临床分期、浸润深度无关(P>0.05)。E-cadherin与OPN的表达呈负相关(r=-0.321,P<0.01)。结论 E-cadherin表达降低或缺失及OPN的高表达与宫颈癌的发生、浸润及转移密切相关,联合检测E-cadherin和OPN可为宫颈癌的治疗和预后提供有价值的临床信息。
