Current and Former Smokers: Who Wants To Be Screened?
Résumé
Participation is key to the success of cancer screening. Identifying the reasons for nonparticipation is therefore essential. The present analysis of the EDIFICE (etude sur le depistage des cancers et ses facteurs de compliance [survey on cancer screening and compliance factors]) surveys (n = 1463) found 36.4% of current smokers and 26.3% of former smokers intended to participate in a lung cancer screening program. Discrepancies exist between the screening program target populations and the individuals who actually intend to undergo screening. Background: Lung cancer (LC) screening (LCS) with annual low-dose computed tomography scans has been seen to reduce the specific and overall mortality in selected populations. However, participation is key to successful screening programs. The EDIFICE (etude sur le depistage des cancers et ses facteurs de compliance [survey on cancer screening and compliance factors]) nationwide observational surveys are used to assess behavior related to cancer screening programs in France. Materials and Methods: Using comprehensive multivariate stepwise logistic regression analyses of data from current and former cigarette smokers, we sought to identify the explanatory factors associated with the intention to participate in an LCS program. Results: Of the 1463 respondents with no personal history of cancer, 263 (36.4%) of the current cigarette smokers and 170 (26.3%) of the former cigarette smokers stated their willingness to participate in an LCS program. The explanatory factors differed between current cigarette smokers (already screened for LC: odds ratio PRI, 2.81; < 30 pack-years: OR, 2.69; intention to quit smoking: OR, 1.96; no social vulnerability: OR, 2.15) and former cigarette smokers (comorbidities: OR, 0.31). The usual eligibility criteria were not significantly explanatory. Conclusion: Our findings highlight the discrepancy that exists between target populations and individuals who actually intend to participate in a screening program for LC, with subsequent potential effects on the participation rates and, thus, on the efficacy of screening.
