Abstract:
ObjectiveTo analyze the incidence and mortality of lung cancer in Beilun District of Ningbo City in Zhejiang Province from 2020 to 2024, and to provide a scientific basis for the prevention and control strategies of lung cancer. MethodsThis study was based on the tumor incidence and mortality surveillance data of registered residents in Beilun District from 2020 to 2024. The crude incidence rate, crude mortality rate, age-standardized incidence rate and age-standardized mortality rate of lung cancer were calculated by gender and age. The Joinpoint software was used to analyze the temporal trends of lung cancer incidence and mortality, and the average annual percent change (AAPC) of lung cancer incidence and mortality was calculated. ResultsFrom 2020 to 2024, a total of 3 496 cases of lung cancer were reported in Beilun District (crude incidence rate: 157.15/100 000, age-standardized incidence rate: 106.28/100 000), and 1 077 deaths were recorded (crude mortality rate: 48.42/100 000, age-standardized mortality rate: 26.00/100 000). The crude incidence rate (164.83/100 000) and crude mortality rate (73.97/100 000) for males were both higher than those for females (150.06/100 000 and 24.70/100 000, respectively). The average ages of lung cancer at diagnosis and death showed upward trends (AAPC=1.53%, 0.46%; t=10.23, 3.27; P=0.002, 0.047). The incidence and mortality rates increased with age, peaking in the 70‒74 age group (452.62/100 000) and the 80‒84 age group (402.63/100 000), respectively. Age-group analysis showed that only the incidence rate in the 50‒54 age group and the mortality rates in the 60‒64 and 70‒74 age groups exhibited downward trends over time (AAPC=-13.03%, -11.12%, -4.46%, P=0.038, 0.048, 0.031), while no significant trends were observed in other age groups. ConclusionThe incidence level of lung cancer among residents in Beilun District is relatively high, with a heavy disease burden and no obvious annual downward trend, posing significant challenges to prevention and control. The government should implement measures including strengthening tobacco control and occupational protection for men, formulating personalized diagnosis and treatment plans for elderly patients, launching kitchen health campaigns and passive smoking intervention for women, and improving the tumor registration and follow-up system to achieve precise gender-and age-specific prevention and control of lung cancer.
