Abstract
Aims and Background
The time of lung cancer screening may provide the ideal setting to discuss and initiate a smoking cessation plan that includes pharmacologic aids. No studies to date have fully investigated the potential effectiveness of such combined approach.
Methods
We prospectively evaluated the biochemically verified 1-year continuous abstinence rate from smoking of 187 persistent smokers enrolled within the Multicentric Italian Lung Detection Trial (MILD), who received a pharmacologic aid to quit smoking with varenicline along with behavioral counseling. The propensity of study subjects to succeed in smoking cessation was also monitored.
Results
At 12 months, the continuous abstinence rate from smoking was achieved in 37 out of 187 patients (19.8%), with a propensity to succeed in smoking cessation for the assisted attempt equal to 1.43, as compared to an unassisted MILD patient. At the end of the third month of therapy, 48.7% of subjects showed a continuous abstinence rate, while only 33.7% of patients were abstinent from smoking at 6 months. At baseline, the subgroup of MILD participants who were originally allocated to lung tomography showed higher smoking intensity than those allocated to no screening.
Conclusions
A combined smoking cessation intervention can be implemented with satisfactory results within a lung cancer screening program; this preliminary observation needs to be replicated in a prospective investigation. Clinicians should consider that lung cancer screening may be falsely reassuring for persistent smokers; therefore it should always be coupled with a smoking cessation program.
