NCT05645731

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 Outcomes (2)

  • Mean number of referrals for lung cancer screening per participants

    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.

    2 weeks post inclusion

  • Mean PLCOm2012 risk prediction model score among referred participants

    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.

    baseline

Secondary Outcomes (9)

  • Number of visitors on our website for referred participants

    6 months

  • Number of people who started to fill the enrollment form for referred participants.

    6 months

  • Number of referred participants who enrolled in the study.

    6 months

  • 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

  • +4 more secondary outcomes

Study Arms (2)

Lung cancer patient

Lung cancer patients or lung cancer survivors willing to refer close contacts for lung cancer screening

Referred participants

Participants referred to the study by close contacts living with lung cancer.
