1、原发性肝细胞癌HBsAg、Fas和PCNA抗原的表达及其意义论文姜润德宗宁李占元王占民【摘要】目的:通过检测原发性肝细胞癌(HCC)及其癌周肝组织HBsAg、Fas抗原和增殖细胞核抗原(PA)的表达,探讨其表达的规律和意义以及HBV感染与HCC的相关关系,HCC发生的机制。方法:对52例肝癌标本及42例癌周肝组织应用免疫组织化学方法检测HBsAg、Fas和PA的表达,并结合血清甲胎蛋白(AFP)水平进行分析。结果:癌周肝组织高度表达HBsAg和Fas,阳性率均达78.6%,癌组织表达阳性率分别为21.2%和30.8%,阳性表达仅限于分化良好者,差异有统计学意义(P均<0.005)。癌组织和癌
