本文根据国际癌症研究机构(IARC)1982年出版的《五大洲癌症发病率,卷Ⅳ》、以及《五大洲癌症发病率,卷Ⅲ》和国内外有关肝癌发病率的一些资料,进行比较分析如下。 一、地理分布特点 世界一些国家(地区)肝癌年发病率见附表。按照国际抗癌联盟(UICC)将世界男性肝癌发病率分成三组(第一组年发病率超过5.0/10万的地区,第二组年发病率在3.1—5.0/10万的地区,第三组年发病率在3.1/10万以下的地区)进行观察。结果发现世界肝癌多发生于亚洲、非洲和欧洲东南部。较少见于北
Based on the IARC’s “The Incidence of Cancer on Five Continents, Vol. IV”, and “The Incidence of Cancer on Five Continents, Volume III” published by the International Agency for Research on Cancer (IARC) in 1982, and some data on the incidence of liver cancer at home and abroad, a comparative analysis is provided below. . I. Geographical distribution characteristics The annual incidence of liver cancer in some countries (regions) of the world is shown in the attached table. According to the International Union Against Cancer (UICC), the incidence of the world’s male liver cancer is divided into three groups (the first group has an annual incidence of more than 5.0/10 million in the region, and the second group has an annual incidence of 3.1-5.0 per 100,000 in the region, and the third The annual incidence in the group was 3.1/100,000 or less). As a result, it was found that liver cancer in the world mostly occurred in Asia, Africa, and Southeastern Europe. Less common in northern
