Abstract:
Background and objective hTe lung cancer incidence was signiifcantly increased in the past two de-cades in China. But the secular trend of lung cancer incidence difference between gender (male and female), area (urban and rural) and average age was not clear. hTe aim of this study is to analyze the trend of lung cancer incidence rate ratio between gender, area and average age in China during 1989-2008, and provide some inspiration for lung cancer prevention and control activities. Methods Cancer registry data and population data in China from 1989 to 2008 were collected by the National Cancer Registration Center. Stratiifed for gender and area, Poisson regression model was used to estimate annual lung cancer incidence rate ratio between male and female, urban and rural areas. hTe average age of lung cancer incidence was calculated. Linear regression was used to model the trend of annual incidence rate ratio and average age over time. Results Incidence rate ratios of lung cancer between male and female, urban and rural areas were signiifcantly decreased from 2.47 and 2.07 to 2.28 and 1.14 during 1989-2008, respectively. Meanwhile, the average age of lung cancer incidence among male and female dramati-cally increased from 65.32 and 65.14 to 67.87 and 68.05, respectively. Conclusion hTe difference of lung cancer incidence between male and female, urban and rural areas remarkably decreased from 1989 to 2008. hTe average age of lung cancer oc-currence gradually increased. Researches, prevention and control activities on lung cancer with consideration of new incidence pattern should be strengthened.
