Estimating the Impact of Asthma and COPD on Lung Cancer Screening in the USA.

Objectives: Examine the association of asthma, COPD, and Asthma-COPD overlap (ACO) on rates of lung cancer screening.

Methods: 2022 Behavior and Risk Factors Surveillance Survey was used for cross-sectional analysis of self-reported lung cancer screening prevalence in those with COPD, asthma, and ACO, with stratification by smoking status. Multivariate logistic regression was performed to assess the relationship between asthma, COPD, ACO and lung cancer screening status.

Results: 17.9% of eligible adults were up-to-date on lung cancer screening. Those with COPD and ACO had higher rates of ever undergoing lung cancer screening (50.8% and 47.5%) than those with asthma (26.4%) or neither condition (23%). Adults with COPD (adjusted odds ratios (aOR): 2.86, 95% CI 2.49-3.28) and ACO (aOR: 2.85, 95% CI 2.49-3.28) had increased odds of ever having lung cancer screening compared with those without either condition. Stratification by smoking status shows that individuals who formerly smoked had slightly higher odds of ever undergoing screening than individuals currently smoking.

Conclusion: Lung cancer screening rates have increased; however, it remains low. Adults with COPD and ACO are more likely to undergo lung cancer screening.
