Lung Cancer Screening in Family Members and Peers of Lung Cancer Patients: a Prospective Cohort Study
Study Details
Study Description
Brief Summary
Lung cancer screening of active or former heavy smokers with yearly low-dose CT allows for earlier diagnosis and better lung cancer survival. Risk of developing lung cancer is higher among family members and close contacts of lung cancer patients, because of shared genetics, environment and life habits like smoking. The investigators want to engage lung cancer patients to refer their family members and close contacts for lung cancer screening, and evaluate if this referred population have higher risk of lung cancer than the population referred by their family doctors.

Outcome Measures
Primary Outcome Measures
- Mean number of referrals for lung cancer screening per participants [2 weeks post inclusion]
Mean number of referrals for lung cancer screening per participants: lung cancer participants will refer contacts directly on the REDCap questionnaire at enrollment. They will be contacted a second time 2 weeks after enrollment and asked if they referred additional people in their entourage for lung cancer screening.
- Mean PLCOm2012 risk prediction model score among referred participants [baseline]
Mean risk of developing lung cancer in the next 6 years using the validated PLCOm2012 risk prediction model in smokers or ex-smokers referred participants that are 55 to 74 years old.
Secondary Outcome Measures
- Number of visitors on our website for referred participants [6 months]
Quantification of people who visited the website for close contacts of lung cancer patients: Number of unique access to website based on google analytics data.
- Number of people who started to fill the enrollment form for referred participants. [6 months]
Number of people who started to fill the enrollment form for referred participants.
- Number of referred participants who enrolled in the study. [6 months]
Number of referred participants who enrolled in the study.
- PLCO score as a binary outcome (above or below 2%) among referred participants [baseline]
- Proportion of LCS eligible participants who will complete lung cancer screening within 18 months of referral by a lung cancer patient [18 months]
Proportion of LCS eligible participants who will complete lung cancer screening within 18 months of referral by a lung cancer patient
- Proportion of individuals who would theoretically demonstrate interest in genetic testing to assess for lung cancer risk. [baseline]
Proportion of individuals who would theoretically demonstrate interest in genetic testing to assess for lung cancer risk.
- Proportion of individuals who demonstrate interest in referral to a smoking cessation program among referred participants that are current smokers [baseline]
Proportion of individuals who demonstrate interest in referral to a smoking cessation program among referred participants that are current smokers
