Objective To systematically review the association between inhaled corticosteroids (ICS) and the risk of lung cancer in patients with chronic obstructive pulmonary disease (COPD). Methods PubMed, EMbase, Web of Science, Cochrane Library, CNKI, WanFang Data and VIP databases were electronically searched to collect cohort studies on the risk of lung cancer in COPD patients using ICS from inception to August 15, 2022. Two reviewers independently screened the literature, extracted data, and evaluated the risk of bias of the included studies. Meta-analysis was then performed by using RevMan 5.4 software. Results A total of 8 cohort studies involving 1 184 238 patients were included. The results of meta-analysis showed that ICS use decreased risk of lung cancer in COPD patients (HR=0.68, 95%CI 0.62 to 0.75, P<0.01). The dose of ICS was an influencing factor for the risk of lung cancer in COPD patients and a large dose of ICS could significantly reduce the risk. Conclusion Current evidence shows that the use of ICS can reduce the risk of lung cancer in patients with COPD, especially in high-dose patients. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
