原发性肝癌(以下简称肝癌)居我国癌症死亡的第3位,也是世界上广泛流行的恶性肿瘤之一。目前乙型肝炎在肝癌发生中的作用正受到愈来愈多的关注。全世界约有2亿以上的人携带乙型肝炎病毒(HBV),已有大量的证据表明HBV持续感染与肝癌的发生有关。世界卫生组织肝癌预防会议指出HBV与肝癌有一个密切的特定的因果关系。
Primary liver cancer (hereinafter referred to as liver cancer) ranks third in cancer deaths in China and is one of the most widespread malignancies in the world. At present, the role of hepatitis B in the development of liver cancer is receiving more and more attention. More than 200 million people worldwide carry Hepatitis B virus (HBV). There is ample evidence that persistent HBV infection is associated with the development of liver cancer. The World Health Organization conference on liver cancer prevention pointed out that HBV and liver cancer have a close and specific causal relationship.
