摘要
作者应用抗HCVNS3区C33c抗原2B6株单克隆抗体和抗HBxAg多克隆抗体,采用ABC法对102例人原发性肝细胞肝癌(PHC)组织进行了HCV及HBV抗原定位研究。HCVC3。抗原及HBxAg在PHC中的阳性检出率分别是81.4%及74.5%,C33c抗原或HBxAg阳性占所检病例94.1%,相同病例二者同时阳性为61.8%。102例PHC中50例有癌旁肝组织,其C33c抗原和HBxAg的阳性检出率分别是62%和92%。HCVC33c抗原定位于肝癌细胞的胞浆内,胞核未见阳性信号。C33c抗原阳性细胞在PHC中呈散在、局灶分布为主,在癌旁肝组织呈弥漫分布为主。本文结果提示HCV感染在PHC的发生中可能起重要作用。
In order to explore the relationship between HCV infection and primary hepatocellular carcinoma(PHC),HCV NS3 region C33c antigen and HBxAg were detected with monoclonal antibody to C33c antigen and polyclonal antibody to HBxAg by immunohistochemistry method in paraffin-embedded sections of PHC tissues.in 102 cases The positive rate of HCV C33cantigen and HBxAg was 81.4%(33/102) and 74.5%(76/102) respectively.The overall detection rate of HCV C33c and HBxAG was 94.1% (96/102).The double positive rate of HCVC33c and HBxAg was 61.3%(63/102).Among 102 PHC cases,50 cases were with nontumorous liver tissues,in which positive rate of HCV C33c antigen and HBxAg in it was 64%(32/50) and 92%(46/50) respectively.HCV C33c antigen was clearly stained in the cytoplasm of cancerous cell and hepatocyte and not in the nucleus or cell membrane.The positive substance was distributed locally or diffusely in the cytoplasm of cancerous cell.Three main types of distribution pattern of HCV C33c antigen positive cell were observed.They were patchy.cluster and diffuse.The main pattern in PHC was patchy and cluster,which that in nontumorous liver tissues was diffuse.Our results suggest that HCV infection is very common in PHC patients in Xi'an area.and it may play an important role in the development of PHC except HBV infection.
