Abstract: Objective The aim of this study was to analyze the incidence and mortality of lung cancer in Hedong district,Tianjin,from 2015 to 2020,and provide data for strategies of the prevention and treatment of lung cancer. Methods The data of lung cancer incidence and mortality registered residents of Hedong district in Tianjin from January 1,2015,to December 31,2020 were collected from the Tianjin Tumor Follow-up Registration System and the Population Death Information Registration System.The crude incidence and mortality,China standardized incidence and mortality by sex and age were calculated.The Joinpoint regression model was used to analyze the trend of incidence and mortality of lung cancer. Results The crude incidence of lung cancer in Hedong district,Tianjin,from 2015 to 2020 was 106.51/100,000(male 135.99/100,000 and female 77.21/100,000).The China standardized incidence was 40.80/100,000(male 50.84/100,000 and female 30.70/100 000).The crude mortality of lung cancer was 87.96/100,000(115.60/100,000 for males and 60.49/100,000 for females).The China standardized mortality was 31.58/100,000(40.85/100,000 for males and 22.17/100,000 for females).The incidence and mortality of lung cancer in Hedong district increased with age,reaching the peak in the 80~ years old age group.The China standardized incidence of lung cancer(APC=-5.6%,P＜0.05),the China standardized incidence of female lung cancer(APC=-6.7%,P＜0.05),and the China standardized mortality of female lung cancer(APC=-6.5%,P＜0.05)all showed a downward trend. Conclusion The incidence of lung cancer in Hedong district,Tianjin,showed a downward trend,and the mortality did not change significantly.The incidence and mortality of men are higher than those of women.Age is an important factor affecting the occurrence and development of lung cancer,and elderly people should be the focus of daily intervention.
