广东省揭阳市肝癌流行病学调查

目的 了解揭阳市人群中肝癌的分布,为病因学研究指明方向。 方法 我们将揭阳市1981-1990年死于肝癌的居民死亡登记卡片,按揭阳的21个镇分别进行统计分析。标化率用国家1982年公布人口构成计算,显著性检验用二个标化率比较。 结果 揭阳市1981-1990年死于肝癌共3257人,累计人口数13233148人,年平均死亡率24.6/10万,中国人口标化死亡率24.1/10万,世界人口标化死亡率30.3/10万。10年中男性累计死亡数2471人,年平均死亡率35.99/10万,中国人口标化死亡率38.7/10万,世界人口标化死亡率49.2/10万;女性年平均死亡率12.3/10万,中国人口标化死亡率111.0/10万,世界人口标化死亡率14.0/10万。男女之比为3.5:1。死亡率随年龄增长而上升。平原地区死亡率略高于丘陵地带。 结论 揭阳市是广东省肝癌发病较高地区,死亡率有上升现象。死亡率较高地方是榕江沿岸,值得进一步研究。

Epidemiologic investigation of liver cancer in Jieyang city of Guangdong province

AIM To study the epidemiology of liver cancer in Jieyang city Guangdon province for etiology research.METHODS The resident - death registered cards of liver cancer from 1981 to 1990 in 21 towns in Jieyang city was analysed statistically. The standard mortality was counted with population structure published by Chinese Nation in 1982. The significance test was compared in twostandard ratesRESULTS The total patients died from liver cancer were found to be 3257 in Jieyang city from 1981 to 1990. The annual average mortality was found to be 24.6/100000, the standard mortality of Chinese population was 24.1/100000 and that of the world population was 30.3/100 000. The males died in the past 10 years were found to be 2471, the annual average mortality was 36.0/100000, the standard mortality of Chinese population was 38.7/100000 and that of the world population was 49.2/100000, and that was 12.3, 11.0 and 14.0 per 100000 respectively in the females. The male/female ratio is 3.5/1. The mortality increased with the age growing. The mortality was higher in the plain than in the hillycountry.CONCLUSION Jieyang city is one of the high incidence area in Guangdong province. The higher mortality area is along the bank of Rong river. It is of importance to study further.
