Overwhelming support among urban Irish COPD patients for lung cancer screening by low-dose CT scan

Purpose: The National Lung Screening Trial (NLST) has renewed interest in low-dose computed tomography (LDCT) screening for lung cancer. Smokers may be less receptive toward LDCT screening, however, compared with never smokers. The views of patients with COPD, a particularly high-risk group, toward LDCT screening for lung cancer are currently unknown. We therefore evaluated attitudes of patients with COPD toward LDCT screening for lung cancer. Methods: Interviews with Irish patients with COPD who satisfied NLST eligibility criteria were conducted in clinical settings using a questionnaire based on that of a comparable study of U.S. current/former smokers of unspecified disease status. Results: A total of 142 subjects had a mean age of 65.09 ± 6.07 years (46.4 % were male, mean pack years 54.5 ± 33.3, mean FEV1 59.16 ± 23 %); 97.8 % had an identifiable usual source of healthcare. Compared with data from a U.S. cohort of current/former smokers, a higher proportion of Irish COPD smokers: believed that they were at risk for lung cancer (63.6 vs. 15.7 %); believed that early detection improved chances of survival (90 vs. 51.2 %); were willing to consider LDCT screening (97.9 vs. 78.6 %); were willing to pay for a LDCT scan (68.6 vs. 36.2 %); and were willing to accept treatment recommendations arising (95.7 vs. 56.2 %; p < 0.0001 for all comparisons). Conclusions: Urban Irish smokers with COPD who would be eligible for LDCT screening are almost universally in favor of being screened and treated for screening-detected lung cancers. This readily accessible high-risk population should be actively targeted in future screening programs.
