原发性肝癌与HBV、HCV感染关系

Relationship between primary hepatocellular carcinoma and HBV,HCV infection

目的:了解乙型肝炎病毒(HBV)、丙型肝炎病毒(HCV)在原发性肝细胞癌(HCC)发生中的作用以及两种病毒的相互关系。方法:168例HCC组和182例正常组的配对对照研究。结果:HCC组中HBV-DNA和HCV-RNA阳性率分别为74.4%及11.9%,显著高于对照组的10.4%和3.3%,HBV-DNA或HCV-RNA阳性以及两者均阳性时发生HCC的相对危险度分别为52.7、30.2和84.0。此外,原发性肝癌还与既往肝硬化史、家族肝癌史有关,且以男性高发。结论:原发性肝癌的发生受多种因素影响,尤其HBV和(或)HCV慢性感染是主要危险因素之一。HBV感染除可能有直接致癌作用外,还可与HCV有协同致癌作用。

Objective：To know effect of chronic hepatitis B virus（HBV） and chronic hepatitis C virus（HCV） infection on hepatocellular carcinoma（HCC） and their relation.Methods：HBV-DNA and HCV-RNA values were obtained from 168 patients with HCC（HCC group） and 182 healthy individuals（control group）.Results：Positive rate of HBV-DNA and HCV-RNA was 74.4% and 11.9% in HCC group remarkably higher 10.4% and 3.3% in control group,HCV-RNA car-riage was present in of HCC patients and 3.3% of healthy individuals.Increased HCC risk was strong associated with chronic HBV（52.7）,HCV（30.2）,and dual infection（84.0）.The same difference existed in HCV infection.Moreover,the history of hepatitis B and cirrhosis were also found relating to HCC.Conclusion：There are several factors relative to HCC,and the main risk factors are HBV and HCV infection.In addition to nature of risk with coinfection as representative of HBV and HCV acting primarily through share steps in the multistage process of hepatocarcinogenesis.
