近年国外文献继续表明,原发性肝癌发病率以非洲撒拉哈沙漠以南和亚洲太平洋沿岸地区为高,而欧美、大洋洲则历来较少见。男性的发病率欧美一般在3.0/10万以下,而亚非某些地区多在5.0/10万以上(日本4.6/10万,新加坡5.5/10万,乌干达5.5/10万,尼日利亚5.9/10万,南非14.2/10万,莫三鼻给高达98.2/10万)。以尸检中所占百分比来看,1958年Berman报导,欧美多在0.3％以下,近年虽有上升,但仍在1％以下。而亚非某些地区则始终在1％以上,如日本为1.94％。
In recent years, foreign literature has continued to show that the incidence of primary liver cancer is higher in the south of the Salarha Desert in Africa and the Pacific Rim in Asia, while Europe, the United States, and Oceania have historically been less common. The incidence of men in Europe and the United States is generally 3.0/100,000 or less, while in some Asian and African regions it is more than 5.0/100,000 (Japan 4.6/10 million, Singapore 5.5/10 million, Uganda 5.5/10 million, Nigeria 5.9/10 million , South Africa 14.2 / 100 thousand, Mo three nose gives up to 98.2/10 million). In terms of the percentage of autopsies, Berman reported that in 1958, Europe and the United States were mostly below 0.3%. Although they have risen in recent years, they are still below 1%. In some Asian and African regions, it is always above 1%, for example, Japan is 1.94%.
