Changes in NSCLC proportions over the past 28 years. (A) The proportion of never-smokers in all lung cancer patients increased over time; (B) the proportion of never-smokers increased significantly in those with adenocarcinoma; (C) the proportion of never-smokers did not change significantly in those with squamous cell carcinoma; (D) the proportion of female patients has increased over time; (E) most female patients had LUAD; (F) the proportion of female adenocarcinoma patients who never smoked increased significantly over time; (G) the proportion of lung adenocarcinoma patients increased over time; (H) the proportion of lung squamous cell carcinoma patients decreased over time; (I) the proportion of patients diagnosed with lung cancer without symptoms significantly increased; (J) the proportion of asymptomatic non-smoking female adenocarcinoma patients significantly increased; (K) the proportion of patients aged 60 years and older increased in the lung cancer patients surveyed; (L) among patients aged 60 years and older, the proportion of patients with adenocarcinoma increased. NSCLC, non-small cell lung cancer; NSLC, never-smoking non-small cell lung cancer; LUAD, lung adenocarcinoma; LUSC, lung squamous cell carcinoma; NSLUAD, never-smoking lung adenocarcinoma; NSLUSC, never-smoking lung squamous cell carcinoma. ns, P≥0.05; *, P<0.05; **, P<0.01; ***, P<0.001.
