[Lung cancer incidence and mortality in China in 2013].

Abstract

Objective: Lung cancer incidence and mortality were estimated by sorting and analyzing the national cancer registration data in 2013. Methods: Lung cancer data of 2013 were retrieved from the database of 255 qualified cancer registries. Lung cancer incidence and mortality rates in cancer registration areas in 2013 were estimated by areas (urban/rural), gender and age groups, new lung cancer cases and deaths were estimated using age-specific rates by areas and gender using the corresponding population in 2013. Lung cancer incidence and mortality rates in China in 2013 were calculated based on the estimated new cancer cases and deaths and the corresponding population. The Chinese population in 2000 and Segi's world population were used to calculate age-standardized rates. Results: It was estimated that there were about 732.8 thousand new lung cancer cases and 580.7 thousand deaths occurred in China in 2013. The crude incidence rate was 53.86/10(5)(males 70.10/10(5,) females 36.78/10(5)), while age-standardized incidence rate by Chinese standard populations (ASIRC) and by world standard populations (ASIRW) were 36.19/10(5) and 36.09/10(5) with the cumulative incidence rate (0-74 years old) of 4.42%.The crude mortality rate was 43.41/10(5)(males 57.64/10(5,) females 28.45/10(5)), and age-standardized mortality rate by Chinese standard populations (ASMRC) and by world standard populations (ASMRW) were 28.64/10(5) and 28.41/10(5) with the cumulative incidence rate (0-74 years old) of 3.34%.Both incidence and mortality rates were higher in males than in females. Crude incidence and mortality rates were slightly higher in urban areas than in rural areas, but after age standardized, the results were opposite. Conclusions: Lung cancer is the common cancer, which both incidence and mortality rates are ranking first in China, and the burden of the disease is heavy. Comprehensive measures towards risk factors control, cancer early diagnosis and treatment should be strengthened continuously.
