Objective To study the prevalence of combined pulmonary fibrosis and emphysema (CPFE) in a community-based lung cancer screening program in Shanghai. Methods From June 2018 to July 2019, eligible participants who were assessed through a high-risk lung cancer questionnaire in Xuhui, Shanghai underwent low-dose computed tomography of the lungs. The suspected CPFE patients were invited to provide medical history and blood for analysis, and received high-resolution CT (HRCT) scanning for confirmation. Results Of the 15 cases of suspected CPFE from a total of 4478 participants in which 1704 males and 2774 females, 4 declined further examination and 11 received further examine. Eight subjects were confirmed as CPFE, and all were male, of whom two were ex-smokers and six were active smokers. These CPFE patients had cough, chest tightness and dyspnea. There were 3 cases of centrilobular emphysema, 2 cases of paraseptal emphysema, 1 case of panlobular emphysema and 2 cases of mixed emphysema. There were 2 cases of usual interstitial pneumonia, 3 cases of non-specific interstitial pneumonia, 2 cases of airspace enlargement with fibrosis and 1 case of unclassifiable smoking-related interstitial fibrosis. The KBILD scores were 61.7±7.5 and mMRC scores were 1.5±0.8. Serum Krebs von den Lungen-6 concentration was (380.75±212.05)U/mL. Lung function test showed normal or mild restrictive ventilatory function, and mild-moderate impairment in diffusion capacity. Conclusions The prevalence of CPFE is 1.79‰ in a community-based lung cancer screening population, and is 4.69‰ in male lung cancer screening population.
