为研究乙型、丙型和庚型肝炎与原发性肝癌的关系，对我国江苏海门、福建同安、广西扶绥和河北石家庄四地，进行了以人群或医院为基础的肝癌病例对照研究。在四个地区病例与对照中，ＨＢｓＡｇ阳性率分别为６６．３％（２３８／３５９）和２３．４％（８４／３５９），其ＯＲ值为６．６０；抗－ＨＣＶ阳性率分别为１７．９％（６１／３４０）和６．５％（２２／３４０），ＯＲ＝３．３１；合并乙丙型肝炎感染其肝癌危险度大大增加（ＯＲ＝１１０．０８）。另对海门病例对照各５０例进行ＨＧＶ－ＲＮＡ检测，阳性率分别为２２％和１０％。结果说明：在我国乙型肝炎感染与肝癌关系更为密切
To study the relationship between hepatitis B, C and G hepatitis and primary hepatocellular carcinoma, population-based or hospital-based hepatocellular carcinoma (HCC) case-control study was conducted in Haimen, Jiangsu Province, Tong’an, Fujian Province, Fusui, Guangxi Province and Shijiazhuang, Hebei Province. The positive rates of HBsAg were 66.3% (238/359) and 23.4% (84/359) in the four district cases and controls, respectively, with an OR of 6.60; the positive rates of anti-HCV were 17 .9% (61/340) and 6.5% (22/340), OR = 3.31. The risk of hepatocellular carcinoma was significantly increased with hepatitis B infection (OR = 110.08). Another 50 cases of Haimen case control HGV-RNA detection, the positive rates were 22% and 10%. The result shows that hepatitis B infection is more closely related to liver cancer in our country
