PURPOSE: The importance of smoking cessation interventions in lung cancer screening participants has been highlighted previously. Individuals enquiring about screening, but not meeting eligibility criteria may represent another group who may benefit from smoking cessation activities associated with a screening program even if they do not actually proceed to screening. This study was designed to describe the tobacco habits of this cohort.

METHODS: Albertans between the ages of 55 and 80 with a history of smoking were invited to participate in the Alberta Lung Cancer Screening Program (ALCSP). A baseline questionnaire exploring tobacco use was administered to all interested individuals as part of the eligibility determination for the program. Eligible participants had a 1.5 % or greater lung cancer risk over 6 years or met the National Lung Screening Trial (NLST) inclusion criteria.

RESULTS: Baseline questionnaires were received from 277 individuals, with 130 (46.9%) meeting the criteria for the ALCS and 146 (52.7%) non-eligible for screening. Non-eligible individuals were younger (58.2 vs. 63.2 years, p-value=0.000), more likely to be female (62.1% vs. 48.5%, p-value=0.023) and less likely to be current smokers (32.4% vs. 50.0%, p-value=0.000). Non-eligible participants had a lower degree of addiction compared to eligible group, as measured by the Fagerström Test of Nicotine Dependence (3.6 vs 5.3, p-value=0.001), but still in the “moderately dependent” range for this test. There were no significant differences in passive smoking history, or smoking other products rather than cigarette (Marijuana/pot was the most commonly used product after cigarette) between two groups. There were no significant differences between motivation to quit [(“Intention to quit at any time”; non-eligible:100.0%, eligible: 95.4%, p-value=0.263), “intended to quit soon” (in the next 30 days): non-eligible:49.2%, eligible: 50.8%, p-value=0.249), and “motivation to receive help with their quit attempt”: non-eligible: 89.4%, eligible: 87.7%, p-value = 0.999] or prior attempts to quit in the last 12 months (non-eligible:59.6%, eligible: 52.3%, p-value=0.564) between these two groups. Only 4.3% of non-eligible and 1.5% of eligible smokers were currently in a smoking cessation program.

CONCLUSIONS: A significant proportion of individuals enquiring, but not qualifying for a lung cancer screening program, are active smokers with significant nicotine dependence. Very few are currently participating in active smoking cessation programs but almost all are interested in quitting and in receiving help with quit attempts. Interactions with a lung cancer screening program may represent an opportunity to provide smoking cessation support to smokers even if they do not qualify for screening.

CLINICAL IMPLICATIONS: Identifying and supporting individuals who may benefit from smoking cessation interventions as part of a lung cancer screening program may be of benefit, even for individuals who do not meet recommended screening criteria.
