Trends in incidence and mortality of lung cancer in Kaihua County from 2011 to 2022 / 预防医学

ABSTRACT

Objective@#To investigate the trends in incidence and mortality of lung cancer in Kaihua County, Zhejiang Province from 2011 to 2022, so as to provide insights into improving lung cancer prevention and control strategy.@*Methods@#The incidence and mortality of lung cancer in Kaihua County from 2011 to 2022 were collected through Zhejiang Provincial Chronic Disease Surveillance Information Management System. The crude incidence, standardized incidence, crude mortality and standardized mortality of lung cancer were analyzed, and the trends in incidence and mortality of lung cancer were evaluated using average annual percent change (AAPC). @*Results@#The crude and standardized incidence of lung cancer appeared a tendency towards an increase (AAPC=5.409% and 2.957%, both P<0.05) from 2011 to 2022, with an average annual crude incidence of 75.17/105 and average annual standardized incidence of 44.37/105. Average annual crude incidence (100.16/105 vs. 48.55/105) and standardized incidence (58.03/105 vs. 30.61/105) of lung cancer was higher in males than in females (both P<0.05). The crude incidence of lung cancer in males appeared a tendency towards an increase (AAPC=2.878%, P<0.05), with no significant changing patterns seen in standardized incidence (P>0.05). The crude and standardized incidence of lung cancer in females showed a tendency towards an increase (AAPC=11.596% and 10.464%, both P<0.05). The crude incidence of lung cancer increased rapidly among residents at ages of 45 years and older, and peaked among residents at ages of 80 to 84 years (32.11/105). The crude and standardized mortality of lung cancer appeared a tendency towards a rise and decline (AAPC=1.554% and -2.491%, both P<0.05) from 2011 to 2022, with an average annual crude and standardized mortality of 52.83/105 and 29.09/105. Average annual crude mortality (77.92/105 vs. 26.10/105) and standardized mortality (43.66/105 vs. 14.33/105) of lung cancer was higher in males than in females (both P<0.05). The crude mortality of lung cancer in males appeared a tendency towards a rise, while the standardized mortality appeared a tendency towards a decline (AAPC=1.436% and -2.553%, both P<0.05). No significant changing patterns were seen in crude and standardized mortality of lung cancer in females (both P>0.05). The crude mortality of lung cancer increased rapidly among residents at ages of 50 years and older, and peaked among residents at ages of 80 to 84 years (37.26/105).@*Conclusions@#The incidence and mortality of lung cancer appeared a tendency towards an increase in Kaihua County from 2011 to 2022, and a rapid increase was seen in the incidence of lung cancer in females.
