目的：探讨肝癌高发现场发现早期肝癌的有效方法，查明HBV感染与肝癌的关系。方法：本文应用ELISA方法筛检同安县肝癌高发人群，并对筛检后的HBsAg、AFP阳性人群进行前瞻观察。结果：检出原发性肝癌7例，HBsAg阳性肝癌检出率是HBsAg阴性肝癌检出率的11.6倍（P＜0.01）；前瞻观察结果，发现肝癌20例，HBsAs阳性者肝癌发生率（210、93／10万）是HBsAs阴性着肝癌发生率（3452／10万）的6.11倍（P＜0.01）。结论：表明农村肝癌高发现杨高危人群筛检有一定应用价值，有叶能进一步揭示HBV感染与肝癌的病因学关系。
Objective: To explore the effective method for early detection of liver cancer in the high-risk field of liver cancer, and to identify the relationship between HBV infection and liver cancer. METHODS: This study used ELISA to screen high-risk populations of HCC in Tongan County, and prospectively observed HBsAg and AFP-positive patients after screening. Results: 7 cases of primary hepatocellular carcinoma were detected, the detection rate of HBsAg positive hepatocellular carcinoma was 11.6 times of the detection rate of HBsAg negative hepatocellular carcinoma (P<0.01). The prospective observation results showed that the incidence of hepatocellular carcinoma of 20 cases of hepatocellular carcinoma, HBsAs positive (210 cases) 93/100 thousand) was 6.11 times (P<0.01) higher than the incidence of HBsAs negative liver cancer (3,452/100000). Conclusion: It is indicated that the screening of rural high-risk population with high risk of liver cancer has certain application value, and leaves can further reveal the etiological relationship between HBV infection and liver cancer.
