中国2003-2007年鼻咽癌发病与死亡分析

目的:分析中国2003-2007年鼻咽癌的发病和死亡情况.方法:计算数据符合标准的32个肿瘤登记处的鼻咽癌发病率、死亡率和构成比,以此作为描述中国鼻咽癌流行情况的统计指标.结果:2003-2007年鼻咽癌的总发病率为4.20/10万,中国人口标化率(简称中标率)为2.54/10万,世界人口标化率(简称世标率)为3.08/10万,在恶性肿瘤新发病例构成中排列第17位,占全部恶性肿瘤新发病例的1.58％.鼻咽癌的粗死亡率为2.24/10万,中标率为1.26/10万,世标率为1.61/10万,在恶性肿瘤死亡构成中排列第14位,占全部恶性肿瘤死亡总数的1.31％.鼻咽癌的发病率和死亡率高于全国平均水平的肿瘤登记处均集中在广东省和广西壮族自治区.2003-2007年肿瘤登记地区鼻咽癌发病率和死亡率的变化幅度均不大.结论:鼻咽癌的发病率和死亡率差距相对较大,在中国的分布具有明显的地域特征.

Analysis of the incidence and mortality of nasopharyngeal carcinoma in China between 2003 and 2007

Objective:To analyze the incidence and mortality of nasopharyngeal carcinoma in China between 2003 and 2007.Methods:The incidence and mortality and their proportions of nasopharyngeal carcinoma collected from 32 eligible tumor registries were calculated as the index to describe the epidemiological characteristics of nasopharyngeal carcinoma in China.Results:The crude incidence of nasopharyngeal carcinoma was 4.20/100 000,and the age-standardized incidence by Chinese population(1982) and by world Segi’s population were 2.54/100 000 and 3.08/100 000,respectively.Nasopharyngeal carcinoma accounted for 1.58% of new cancer cases and was ranked as the 17th.The crude mortality of nasopharyngeal carcinoma was 2.24/100 000,and the age-standardized mortality by Chinese population and by world Segi’s population were 1.26/100 000 and 1.61/100 000,respectively.Nasopharyngeal carcinoma accounted for 1.31% of all cancer deaths and was ranked as the 14th.The areas with incidence and mortality higher than the national average were located in Guangdong Province and Guangxi Zhuang Autonomous Region.The changes of incidence and mortality of nasopharyngeal carcinoma were not obvious between 2003 and 2007.Conclusion:The incidence and mortality of nasopharyngeal carcinoma are inconsistent and its distribution is characterized by geographical differences in China.
