Opportunistic screening for lung cancer is commonly conducted in Korea in accordance with physician recommendations and screenee's preferences. However, studies have yet to thoroughly examine the public's understanding of the risks posed by lung cancer screening. This study was conducted to assess changes in intentions to undergo lung cancer screening in response to being informed about exposure to radiation during low-dose computed tomography (LDCT) tests and to identify factors with the greatest influence thereon among Korean men. We conducted sub-group interviews among men chosen from the 2013 Korea National Cancer Screening Survey (KNCSS), a nationwide, population-based, cross-sectional survey of men aged 40 to 74 years and women aged 30 to 74 years. From 4100 participants in the KNCSS, 414 men who underwent any cancer screening test within the last 2 years were randomly selected for inclusion in this study. Via face-to-face interviews, their intentions to undergo lung cancer screening were assessed before and after being informed about exposure to radiation during LDCT testing. Of the 414 participants, 50% were current smokers. After receiving information on the benefits of the test, 95.1% stated an intention to undergo screening; this decreased to 81.6% after they received information on the harms of the test. The average decrease in intention rate was 35.3%. Smoking status, household income, and education level were not associated with lowered intentions to undergo lung cancer screening. Participants who were older than 60 years old (OR=0.56; 95% CI=0.33-0.96) and those with less concern for radiation exposure (OR=0.56; 95% CI=0.36-0.89) were less likely to lower their screening intentions. The results of this study suggest that there is a need to educate both non-smokers and former smokers on the harms of lung cancer screening.
在韩国，肺癌机会性筛查通常是根据医生建议和受检者的意愿进行的。然而，尚未有研究全面考察公众对肺癌筛查风险的理解。本研究旨在评估低剂量计算机断层扫描（LDCT）检查中接触辐射的相关信息对韩国男性肺癌筛查意愿的影响，并确定其中影响最大的因素。我们从2013年韩国全国癌症筛查调查（KNCSS）中选取男性进行分组访谈，该调查是一项基于全国人口的横断面调查，涉及40至74岁的男性和30至74岁的女性。从KNCSS的4100名参与者中，随机选取了414名在过去两年内接受过任何癌症筛查测试的男性纳入本研究。通过面对面访谈，在告知他们LDCT检查中接触辐射的情况前后，评估他们进行肺癌筛查的意愿。414名参与者中，50%为当前吸烟者。在了解到该检查的益处后，95.1%的人表示有进行筛查的意愿；在了解到该检查的危害后，这一比例降至81.6%。意愿率平均下降了35.3%。吸烟状况、家庭收入和教育水平与降低肺癌筛查意愿无关。60岁以上的参与者（OR = 0.56；95% CI = 0.33 - 0.96）以及对辐射暴露不太担心的参与者（OR = 0.56；95% CI = 0.36 - 0.89）降低筛查意愿的可能性较小。本研究结果表明，有必要对非吸烟者和既往吸烟者进行肺癌筛查危害方面的教育。
