定义
最常见和最重要的肝肿瘤是原发性肝细胞癌（HCC）。在世界许多地区，特别是在非洲和亚洲，艾滋病造成了严重的疾病负担。在这些高发地区，慢性乙型肝炎病毒（HBV）感染是主要潜在原因，但日本除外，日本的丙型肝炎感染率很高。乙肝疫苗接种已成为减少肝硬化和肝癌的有力工具，但在一些高危地区的实施仍不理想。在西方国家，长期酗酒是一个主要病因。肝胆管癌的地理分布不同，泰国北部发病率最高。在这里，它是由肝吸虫慢性感染引起的，这是通过受感染的生鱼摄入的。
The most frequent and important hepatic neoplasm is the primary hepatocellular carcinoma (HCC). In many parts of the world, in particular Africa and Asia, it poses a significant disease burden. In these high incidence regions, chronic infection with hepatitis B virus (HBV) is the principal underlying cause, with the exception of Japan which has a high prevalence of hepatitis C infection. HBV vaccination has become a powerful tool in reducing cirrhosis and HCC, but implementation is still suboptimal in several high risk regions. In Western countries, chronic alcohol abuse is a major aetiological factor. Hepatic cholangiocarcinoma has a different geographical distribution, with peak incidences in Northern Thailand. Here, it is caused by chronic infection with the liver fluke, Opisthorchis viverrini, which is ingested through infected raw fish.
