The incidence and mortality of lung cancer in China, 2014 / 中华肿瘤杂志

ABSTRACT

Objective@#To estimate lung cancer incidence and mortality in China using population-based cancer registry data in 2014 collected by National Central Cancer Registry of China (NCCRC).@*Methods@#449 cancer registries submitted cancer registry data in 2014. All datasets were evaluated and 339 registries′ data which met the quality control criteria of NCCRC were analyzed. Numbers of new lung cancer cases and deaths were estimated using calculated incidence and mortality rates and corresponding national population stratified by areas, sexes and age groups. The standard population of Chinese census in 2000 and world Segi′ s population were applied to calculate age-standardized incidence and mortality rates in China and worldwide, respectively.@*Results@#A total of 781, 500 new lung cancer cases were diagnosed in 2014. The crude incidence rate was 57.13 per 100 000 and the age-standardized incidence rates by Chinese standard population (ASIRC) and by world standard population (ASIRW) were 36.71 per 100 000 and 36.63 per 100 000, respectively. The cumulative incidence rate (0-74 years old) was 4.50%. Lung cancer was the most common cancer in male (ASIRW 50.04 per 100 000) and the second most common cancer in female (ASIRW 23.63 per 100 000). The incidence rates were slightly similar in urban areas and in rural areas (ASIRW 36.64 per 100 000 vs 36.56 per 100 000). A total of 626 400 lung cancer deaths were reported. The crude mortality rate was 45.80 per 100 000 and the age-standardized mortality rates by Chinese standard population (ASMRC) and by world standard population (ASMRW) were 28.49 per 100 000 and 28.31 per 100 000, respectively. The cumulative mortality rate (0-74 years old) was 3.32%. Lung cancer was the most common cause of cancer deaths both in male (ASMRW 40.21 per 100 000) and female (ASMRW 16.88 per 100 000). The mortality rate was slightly higher in rural areas than in urban areas (ASMRW 28.63 per 100 000 vs 28.04 per 100 000). Both lung cancer incidence and mortality rates increased with age, and the peak age was 80-84 years group.@*Conclusions@#The disease burden of lung cancer is heavy in China. Efficient national health policies and prevention and control strategies against lung cancer should be promoted.
