原发性肝癌(PHC)是一种高度恶性的肿瘤,发病率高,近年来有增加之势,世界范围的每年有25万多新发病例,许多地区成为男病人最常见的恶性肿瘤。近年来研究证明:PHC的发生与乙型肝炎病毒(HBV)有密切关系,认为持续性HBV感染是发生PHC的重要原因。且PHC高度恶性,病死率高,存活期短,故预防乙型肝炎有更重要意义。一、HBV和PHC的关系 1.PHC的发病率和HBV感染携带率在地区分布上是一致的,即PHC多发生
Primary liver cancer (PHC) is a highly malignant tumor with a high incidence rate and has been increasing in recent years. There are more than 250,000 new cases worldwide each year, and many regions become the most common malignancy for male patients. Recent studies have shown that the occurrence of PHC is closely related to the hepatitis B virus (HBV), and that persistent HBV infection is an important cause of PHC. And PHC is highly malignant, with a high mortality rate and a short survival period, so it is more important to prevent hepatitis B. I. Relationship between HBV and PHC 1. The incidence of PHC and the rate of HBV infection are consistent in the region, that is, PHC occurs frequently.
