摘要: 目的 探讨在乙型肝炎病毒(HBV)相关肝细胞癌(HCC)患者癌组织中HBsAg和肝细胞核因子4α(HNF4α)表达及其与组织学分化的关系。方法 回顾性分析2008年11月~2013年3月首都医科大学附属北京佑安医院经术后病理学检查证实为HCC组织256例。采用免疫组化法检测HBsAg、HNF4α和磷脂酰肌醇蛋白聚糖-3(GPC-3)表达。结果 在256例HCC癌组织中,发现HBsAg阳性12例(4.7%);在39例高分化、119例中分化和98例低分化肿瘤组织中,HBsAg阳性率分别为20.5%、1.7%和2.0%,前组显著高于后两组(P<0.05);HNF4α阳性百分比在高分化癌患者中为65.6%(21/32),显著高于中、低分化癌患者18.8%(3/16,P<0.001);在12例HBsAg阳性癌组织中,HNF4α阳性11例(91.7%),而在选择的36例HBsAg阴性癌组织中,HNF4α阳性13例(36.1%,P<0.05);在4例HBsAg阳性中分化和低分化HCC组织中,免疫组化显示GPC-3呈补丁样分布。结论 HBsAg在HBV相关HCC患者肿瘤细胞中的低表达可能与肿瘤细胞低表达HNF4α有关。

Abstract: Objective To investigate the expression of HBsAg and hepatocyte nuclear factor 4 alpha (HNF4α) in HBV-associated hepatocellular carcinoma(HCC) tissues. Methods The liver cancerous tissues of 256 individuals with HBV-associated HCC from 2008 to 2013 in You-An Hospital affiliated to Capital Medical University were retrospectively reviewed. The expression of HBsAg,HNF4α and glypican-3(GPC-3) were immunohistocamically stained. Results 12(4.7%)out of 256 were found HBsAg positive in tumor tissues; the HBsAg-positive rates in 39 well-differentiated,119 moderately and 98 poorly (2%,2/98) differentiated cancerous tissues were 20.5%(P<0.05),1.7% and 2.0%,respectively;the positive rates of HNF4α in well-differentiated tumor was 65.6%(21/32),much higher than in moderately or poorly differentiated cancerous tissues[18.8%(3/16),P<0.001];11 (91.7%)out of 12 HBsAg positive caner were HNF4α positive,much higher than 36.1% (P<0.05) in 36 with HBsAg negative;the expression of GPC-3 was positive in 4 moderately or poorly differentiated cancerous tissues. Conclusion The low expression of HNF4α might be related to the low expression of HBsAg in HBV-associated HCC tissues,which means the expression of HBsAg should be assisted by the existence of HNF4α.
