1、摘要目的:检测肝细胞癌患者癌组织及对应癌旁组织中CypA表达情况,分析CypA在癌组织中表达差异与患者临床病理特征关系,探讨CypA在肝细胞癌中的临床意义。方法:通过免疫组织化学方法检测了48例病理证实肝细胞癌患者的癌组织及对应癌旁组织中CypA表达情况,用统计学方法分析其表达有无差异,进一步分析癌组织与癌旁组织中CypA表达差异与患者性别、年龄、肿瘤直径、分化程度、肿瘤分级、TNM分期、血AFP水平、血HBSAg等临床病理特征关系。结果:1.CypA在肝细胞癌组织中表达阳性率为79.2%(38/
2、48),癌旁组织CypA表达阳性率为12.5%(6/48),癌组织中CypA表达阳性率明显高于癌旁组织中表达阳性率,两组之间差异有统计学意义(P0.05)。结论:1.CypA在肝细胞癌患者癌组织中呈现高表达,提示CypA可能
3、参与肝细胞癌肿瘤发生发展过程;2.患者肝细胞癌组织中CypA高表达与TNM分期相关,可能成为提示肝细胞癌预后的新标志物。硕士研究生黄晓娟(肿瘤学)指导教师张良明教授关键词:亲环素A;肝细胞癌;免疫组织化学ExpressionofCypAinhepatocellularcarcinomatissuesanditsclinicalsignificance.AbstractObjective:ToobservetheexpressionofCypAinhepatocellularcarcinomatis
