At present, population-based cancer registries were not well established and epidemiologic data for cancer were limited at the province level in China. Using the available mortality data for cancer, estimation model of lung cancer was established to provide the mortality profile for the population in 31 provincial regions in China in 2008.
Based on the population coverage and accuracy of the available mortality for provinces, the methods used to produce mortality estimates fall into 1 of the 3 categories: data were used directly; a model was developed to calculate annual change of mortality rate based on historical and current data; relative frequency data combining with mortality for all sites were used to estimate site-specific mortality.
The total estimated deaths of lung cancer in 2008 were 493,348 (338,346 in males and 155,002 in females) in the whole country. The age-standardized rates were highest in Jilin (52.29 per 100,000 in males and 24.68 per 100,000 in females), and the lowest rates were in Tianjin (24.12 per 100,000 in males) and Chongqing (8.72 per 100,000 in females).
The models for lung cancer mortality at the province level have been established and the data will provide valuable scientific reference for describing the epidemic of lung cancer as well as estimating other site-specific cancer mortality in China.
目前,中国省级层面基于人群的癌症登记体系尚未完善,癌症流行病学数据有限。利用现有的癌症死亡率数据,建立肺癌估计模型,以提供2008年中国31个省级行政区人群的死亡率概况。
根据各省现有死亡率数据的人群覆盖范围和准确性,用于生成死亡率估计值的方法分为三类中的一类:直接使用数据;基于历史和当前数据开发模型来计算死亡率的年度变化;使用相对频率数据结合所有部位的死亡率来估计特定部位的死亡率。
2008年全国肺癌估计死亡总数为493348例(男性338346例,女性155002例)。年龄标准化率在吉林最高(男性为每10万人口52.29例,女性为每10万人口24.68例),最低的是天津(男性为每10万人口24.12例)和重庆(女性为每10万人口8.72例)。
已建立省级层面的肺癌死亡率模型,这些数据将为描述中国肺癌流行情况以及估计其他特定部位癌症死亡率提供有价值的科学参考。
