世界上以非州和东南亚为肝癌的高发地区,而欧美发病率较低。我国以东南沿海如江苏的启东、浙江的嵊泗、福建的同安和广西的扶绥县均为高发区。我国肝癌在男性为第三位多发癌,女性为第四位多发癌。男多于女,约为4～8:1,多见于40～50岁者。原发性肝癌中90％以上为肝细胞肝癌,多数为胆管细胞癌和混合细胞癌。肝癌是死亡率高、治疗困难的癌肿之一,当前临床的研究方向是早期发现亚临床肝癌,正确定位,尽早手术治疗。
In the world, non-state and Southeast Asia are the areas with high incidence of liver cancer, while the incidence rate in Europe and the United States is low. China’s southeast coasts such as Qidong in Jiangsu, Zhejiang, Fujian, Tongan in Fujian and Fusui in Guangxi are high-risk areas. China’s liver cancer is the third most common cancer in men and the fourth most cancer in women. More men than women, about 4 to 8:1, more common in 40 to 50 years old. More than 90% of primary liver cancers are hepatocellular carcinomas, most of which are cholangiocarcinomas and mixed-cell carcinomas. Liver cancer is one of the cancers with high mortality and difficult treatment. The current clinical research direction is to discover subclinical liver cancer early, correctly locate and treat as early as possible.
