Geographical Distribution of Primary Liver Carcinoma and Its Epidemiological Characetri-stics in Guangdong Province

原发性肝癌是我国最常见的三大癌瘤(胃、食管、肝癌)之一,以东南沿海地区为多,广东为高发省份之一,现就其地理分布及发病特点分析如下。 资料来源 一、1970～1972年广东省恶性肿瘤死亡回顾调查。死亡资料是通过组织专业队伍到基层、死者家庭调查取得,其中4/5经县以上医院确诊。

The late of occurrence of primary liver carcimcma in Guangdong Province is very high and the death rate is the highest among all cancers in this province. In Guangdong, primary liver carcinoma has the following geographical distribution and epidemiological characteristics.1. Primary liver carcinoma occurs almost throughout the whole province, and carries a high death rate. The annual average death rate of primary liver carcinoma is 11.33/100,000 population, or annual standardized death rate |10.78/ 100,000 population. It ranks first, among all maliant tumers with a 22.26% rate. It is estimated that more than six thousand victims die of primary liver cancer annually. The death rate of primary liver carcinoma in six out of nine prefectures of Guangdong ranks first among the malignancies. The annual death rate of primary liver carcinoma was the highest in Foshan prefecture (14.38/100,000 population). Among the counties in Foshan, Shunde county was the highest (25.57/100,000 population).2. The ratio of death rate between males and females is 2.88:1, showing males are more prone to develop primary liver carcinoma than females.3. The annual percentage of primary liver carcinoma remained relatively stable but with a tendency to slight increment. It seems that there might be probably the existence of some carcinogenic factors in the environment.
