In fact, 93 million HBV carriers are Chinese, accounting for 2/3 of such patients worldwide, and about 20 million of these people have chronic HBV infection （2）. Chronic HBV infection is a high risk factor for development of HCC. Therefore, the follow-up of those chronic viral hepatitis type B patients and the early-detection of HCC in those patients are pressing tasks to reduce the incidence of HCC in China （3）.展开更多
