Abstract: Objective Incidence and mortality data of lung cancer collected from population-based cancer registries were analyzed in Chinese registration areas from 2003 to 2007.Methods The analysis was based on the data obtained from 32 cancer registries in China.Incidence and mortality were calculated by cancer site,age,gender and area.Age-specific incidence and mortality trends of lung cancer in different areas were analyzed,and the data between China and other countries in the world obtained in the same period was compared.Results The incidence rate of lung cancer was 48.90 per 100,000 in 2003—2007 in China.Lung cancer,which accounted for 18.39% of the total cancer cases,was the most common cancer in China.The mortality rate of lung cancer was 43.48 per 100,000,translating to 25.30% of all cancer death,which was the leading cause of cancer death in China.The incidence and mortality rates in the 5 years kept increasing steadily while a plat level was present after adjusted by the standard population.Compared with 184 countries or areas worldwide,the incidence and mortality rates of lung cancer in China were higher than the average level of the world,ranked the 30th among males and the 13th among females,respectively.In terms of the mortality rate,it was ranked the 55th for men and the 30th for women among 184 countries.Conclusion Lung cancer is the most important cancer threatening people's health in China.Population aging is the main factor,which contributes to the rising of the incidence rate.Urgent prevention and treatment of lung cancer is needed.
