丙型肝炎病毒感染与HCC相关性的研究

目的：探讨丙型肝炎病毒（HCV）感染与肝细胞癌发生的关系。方法：用聚合酶链反应（PCR）对淮南地区92例肝癌、117例肝硬化和100例肝癌切 除的肝组织标本进行HCV-RNA检测，并以限制性片段长度多态性分析对其中89例HCV-RNA阳性血清进行了HCV基因分型。结果：肝癌组HCV感染率29.3%，肝硬化组HCV感染率26.5%，肝组织标本组HCV感染率31.0%；各组均以HCVⅡ型为（65.2%），HCVⅢ型次之（31.5%)。结论：淮南地区肝癌的诱发与HCV感染密切相关，HCVⅡ型在本地区HCV相关性肝癌和肝硬化的发生中可能起主要作用。

Study on the relativity of hepatitis C virus infection and hepatocellular carcinoma

Objective　To study the relationship between HCV infection and hepatocellular carcinoma. Methods　PCR techniques were used to detect the serologic markers of HCV-RNA of 92 patients with hepatocellular carcinoma (HCC), 117 patients with liver cirrhosis (LC) and 100 paraffin-embedded liver tissues from patients from Huainan area. The 89 HCV-RNA positive sera from the 209 patients were analyzed by restriction fragment length polymorphism (RFLP). Results　The infection rates of HCC, LC, liver tissues were 29.3%, 26.5%, 31.0%. HCV genotype of all groups was mainly of type Ⅱ (65.2%) whereas that of type Ⅲ was 31.5%. Conclusion　HCC is associated with the infection of HCV in Huainan area. The infection of HCV type Ⅱ appears to play a main role in the development of HCV-associated HCC and LC in this area.
