ABSTRACT
ObjectiveTo investigate the prevalence of lung cancer among medical staff in a hospital and promote the level of cancer prevention and treatment. MethodsThe annual physical examination data， follow-up pathology and survival data from 2009 to 2021 in a tertiary cancer hospital were collected and then compared with data of lung cancer in China from the global burden of disease database （GBD database）. ResultsThe age-standardized prevalence of lung cancer have been continuously increasing in both populations in recent years. The age-standardized prevalence of lung cancer among medical staff was higher than that in Chinese population， but the age-standardized mortality was lower. The Average Annual Percent Change （AAPC） of lung cancer prevalence among staff was higher than that in Chinese population （13.0% vs. 4.1%）， indicating a higher growth rate. The proportion of newly diagnosed early-stage lung cancer in 2014-2021 was significantly higher than that before adding plain chest CT scan in routine physical examination （2009-2013）， suggesting the benefit of chest CT scan for early screening of lung cancer. ConclusionThe prevalence and growth rate of lung cancer among the staff were higher than those in Chinese population， but the mortality was lower. Plain chest CT scan is essential for early screening and treatment of lung cancer.
