Analysis on trends in lung cancer incidence during 2010-2014 in Jiangxi Province:based on 6 population-based cancer registries

Objective To analyze the trends in lung cancer incidence during 2010-2014 in cancer registries of Jiangxi Province, and provide evidence for the development of strategies for lung cancer prevention. Methods The data of lung cancer in cancer registries of Jiangxi Province were collected to calculate the incidence, age-standardized incidence, cumulative rate, truncated rate, percentage change of incidence (PC), annual percentage change of incidence (APC), etc. The APC was estimated by liner regression based on the logarithm of the incidence rates observed. Results The crude incidence of lung cancer in cancer registries of Jiangxi Province from 2010 to 2014 was 40.57/100 000. The age-standardized incidence by Chinese standard population (ASI China) was 24.99/100 000. The age-standardized incidence by world standard population (ASI world) was 33.44/100 000. The cumulative rate and truncated rate of those aged 0-74 and 35-64 were 4.00% and 44.32/100 000. The lung cancer incidence increased from 38.62/100 000 in 2010 to 43.92/100 000 in 2014. The APC of incidence, ASI China and ASI world were respectively 11.12%,10.46% and 11.38%, but the differences had no statistical significance. The lung cancer incidence showed increasing trend with age, and the increase in male was greater than that in female. Conclusions The lung cancer incidence increased year by year from 2010 to 2014 in cancer registries of Jiangxi Province. Males aged 45 years old and above were at a higher risk of lung cancer.
