Abstract

The National Lung Screening Trial (NLST) revealed that low-dose computed tomography (LDCT) screening reduced lung cancer mortality by 20.0%. In China, LDCT is very cheap and easy to access. As a result, LDCT screening is not limited to "high-risk" population defined by the NLST trial. The results of LDCT screening in China are also quite different from that in Western countries. LDCT detected lung cancer in a significant proportion of young, female and non-smokers in China. There is also a higher proportion of adenocarcinoma (ADC), a lower proportion of squamous cell carcinoma, and a higher proportion of early-stage 0/I disease among LDCT-detected lung cancer in China. The issue of overdiagnosis and overtreatment is discussed. Finally, we call the global attention to clarify the etiology of lung cancer in young female non-smokers.
