1998-2008年中国肾癌发病趋势分析

Analysis for the incidence trends of renal cell carcinoma in China, 1998-2008

目的探讨中国肿瘤登记地区肾细胞癌(RCC,以下简称肾癌)的发病趋势。方法收集整理中国肿瘤登记中心1998-2008年的肾癌登记数据,包括肾癌发病率及年龄别发病率。分别按照性别及城乡差异进行统计,分析中国男性与女性、城市与农村肾癌的发病趋势。结果 1998-2008年,中国肿瘤登记地区肾癌的发病率逐年增长,年均增长率为7.89%。男性发病的年均增长率为8.13%,高于女性的7.51%。城市地区肾癌发病的年均增长率为7.04%,低于农村地区的9.15%。35岁以前的肾癌年龄别发病率处于较低水平,35岁以后的肾癌年龄别发病率呈现较快增长的趋势,75～79岁达到高峰。结论中国属于肾癌发病中等水平的国家之一。但近10年间,不论是男性还是女性,城市还是农村,肾癌的发病率均呈明显增长的趋势,应引起广泛重视。

Objective To investigate the incidence trends of renal cell carcinoma in China. Method The registered renal cell carcinoma data between 1998 and 2008 from the National Cancer Registration Center, including the incidence of renal cell carcinoma and the age-specific incidence, were collected. Statistics made by the difference between male and female, urban and rural to analyze the trends of renal cell carcinoma incidence in China. Result During 1998-2008, the incidence of renal cell carcinoma registered in China was increasing year by year, the average annual growth rate was 7.89%,and the data in males was 8.13% which was higher than that of 7.51% in females. In urban area, the average annual growth rate was 7.04% which was lower than that of 9.15% in rural area. Age-specific incidence rate of renal cell carcinoma was relatively low before 35 years old, and increased sharply since then, reaching peak at the age of 75-79 years. Conclusion China belongs to one of the countries with moderate incidence of renal cell carcinoma. But for the last decade, the incidence showed an obvious rising trend whether males or females, rural or urban, which should be paid more attention to.
