Abstract
Background
Although lung cancer screening (LCS) with low-dose computed tomography (LDCT) reduces
lung cancer mortality in high-risk patients, most of those eligible are not referred
for screening. Tobacco cessation counseling may be an opportune time to educate people
about LCS, but little is known about the utilization and perceptions of LCS among
people undergoing tobacco cessation treatment.
Materials and Methods
We surveyed 185 current smokers, including 122 smokers between the ages of 55 and
80 years, who were attending a tobacco cessation class in a large integrated health
care system regarding lung cancer risk perception and perceived benefits, harms, and
barriers to LCS. We analyzed results according to whether participants had already
undergone LCS and also whether they had undergone colorectal cancer screening.
Results
A minority (18.9%) of participants had undergone LCS, and no participant who had not
undergone LCS was familiar with LCS. Perceived lung cancer risk was high, and screening
was believed to be beneficial. Common barriers included being a current smoker (56.6%),
worrying about test results (52.5%), lack of knowledge about the test (50.8%), absence
of symptoms of lung cancer (40.2%), costs of the study (35.2%), and worrying about
being blamed for having smoked (33.6%). Perceived risk and barriers to LDCT were similar
among people who had or had not previously undergone colorectal cancer screening.
Conclusions
Utilization of LCS was low, and few smokers were aware of LDCT for LCS. A number of
patient-related barriers to screening exist among smokers. Tobacco cessation counseling
may be an opportune time to provide education regarding LCS with LDCT.
