Abstract:
Objective: To analyze the incidence and secular trend of lung cancer in Hexi District, Tianjin, between 1992 and 2012. Methods: To collect the incidence data of lung cancer for residents in Hexi District between 1992 and 2012 from Tianjin Cancer Registry. The lung cancer crude incidence, age standardized incidence, proportion, age specific incidence, cumulative incidence, truncated incidence, percent change and annual percent change were calculated. The incidence and secular trend of lung cancer for male Results: Between 1992 and 2012, a total of 8 177 new cases of lung cancer were collected in Hexi District, the crude incidence was 53.66/100 000, Chinese age standardized incidence was 31.81/100 000, and the world standardized incidence was 31.74/100 000. The crude incidence and standardized incidence of patients with lung cancer in males were higher than those in females. Lung cancer ranked the top 1 among all cancers, accounting for 23.56% of all cancer cases. The cumulative incidence for age 0-64 years was 1.49%, and was 4.05% for age 0 - 74 years. The truncated incidence was 39.83/100 000 for age 35-64 years, and was 274.89/100 000 for age older than 65 years. The incidence of lung cancer increased with age after twenty years old, especially after age 40 years, reaching its peak in age 80-84 years, with incidence of 334.79/100 000. An increasing trend was observed for lung cancer incidence, from 34.99/100 000 in 1992 to 87.37/100 000 in 2012, which increased by 149.70%, and the annual percent change was 4.68%. The incidence for females increased more than males. Increasing trend was also observed for age standardized incidence, though at a lower rate. Conclusion: There is an increasing trend of the incidence of lung cancer in Hexi District, Tianjin. People aged more than 65 years is a high-risk population of lung cancer, therefor the particular attention should be paid for this population.
