Abstract：Objective To estimate the incidence and mortality of lung cancer in 2021 and their trends from 2014 to 2021 within cancer registration areas of Inner Mongolia Autonomous Region, so as to provide the basis for formulating localized strategies for lung cancer prevention and control. Methods The data on lung cancer cases in cancer registration areas of Inner Mongolia Autonomous Region in 2021 were collected from the China Cancer Registration, encompassing data from 55 registries within the region. Crude incidence and crude mortality were calculated by genders, urban/rural rareas, and ages. The Chinese population-standardized rate was calculated using the age structure of the standard population from the Fifth National Population Census in 2000, while the world population-standardized rate was calculated using Segi's world standard population. To assess the trends in Chinese population-standardized incidence and mortality of lung cancer from 2014 to 2021, data from nine qualifying cancer registries were analyzed using the average annual percent change (AAPC). Results In 2021, within Inner Mongolia Autonomous Region, the crude, Chinese population-standardized, and world population-standardized incidences of lung cancer were 58.96/105, 31.58/105, and 31.50/105, respectively. The crude, Chinese population-standardized, and world population-standardized mortalities were 46.48/105, 24.65/105, and 24.36/105 , respectively. The Chinese population-standardized incidence and mortality of lung cancer were 1.59-fold and 1.88-fold higher in males compared to females, and 1.08-fold and 1.10-fold higher in urban areas relative to rural areas. The crude incidence and mortality of lung cancer reached their peaks at age of 80-<85 years (379.91/105 and 474.31/105, respectively). From 2014 to 2021, the Chinese population-standardized incidence of lung cancer in Inner Mongolia Autonomous Region decreased from 43.28/105 to 31.41/105, showed a downward trend (AAPC=-3.312%, P<0.05), while the Chinese population-standardized mortality decreased from 31.55/105 to 24.11/105, showed no statistical significance (P>0.05). The Chinese population-standardized incidence of lung cancer in the group aged ≥75 years and the Chinese age-standardized mortality of lung cancer in the group aged 0-<45 years showed declining trends (AAPC=-4.307%, -7.355%, both P<0.05). Conclusions The disease burden of lung cancer in cancer registration areas of Inner Mongolia Autonomous Region has decreased, showing characteristics where the burden is higher in males than in females and slightly higher in urban areas than in rural areas. The elderly population represents a key group for lung cancer prevention and control.
