Overview
Lung cancer screening using low-dose CT (LDCT) has been shown to reduce mortality in high-risk populations. In 2022, the French National Cancer Institute (INCa) issued guidelines recommending screening for individuals aged 50-74 with a history of heavy smoking, including current smokers or those who quit less than 15 years ago. A national pilot program (IMPULSION) will be launched in 2025.
Lung cancer incidence is strongly correlated with socioeconomic status, yet underserved populations remain difficult to engage in screening programs. Mobile health units using a "reach-out" strategy have demonstrated effectiveness in other countries (UK, Brazil, USA). In France, this approach has been used for breast cancer screening via mobile mammography units.
The MobILYAD project aims to compare two screening modalities- a mobile demedicalized unit (CT-equipped van with trained nurses) and a conventional hospital-based unit- to assess the effectiveness of mobile screening in reaching socially disadvantaged populations.
Eligibility
Inclusion Criteria * :
- Persons aged over 50 and under 75 (74 years of age or older).
- Active smokers or former smokers who quit less than 15 years ago.
- Persons whose consumption is estimated at 20 packs/year or more, down to ≥15 cigarettes/day for a duration of consumption of ≥25 years and up to ≥10 cigarettes/day for ≥30 years, which takes into account the predominance of duration of consumption over quantity consumed in the risk of lung cancer. A pack-year corresponds to the consumption of one pack of 20 manufactured cigarettes per day for one year. A multiplier coefficient will be taken into account depending on the mode of consumption: Rolled cigarettes: 2; Cigarillos: 3; Cigars: 4; Pipes: 2.5; Hookahs: 25.
- Persons affiliated with social security. - Person having signed their consent to
participate in the study after having received full information about it, including
the risks associated with participation.
- Exclusion Criteria * :
- Individuals with severe comorbidities contraindicating lung cancer investigations
and/or treatment (including surgery or stereotactic radiotherapy);
- Individuals with impaired general condition (PS 2 and above);
- Individuals with dyspnea at rest (mMRC4);
- Individuals with a history of cancer undergoing active surveillance by chest computed tomography (CT or PET scan); personal history of lung cancer (lifetime);
- Individuals with symptoms suggestive of lung cancer (hemoptysis, unexplained weight loss, recent onset or change in respiratory symptoms, etc.);
- Individuals refusing to participate in the study
- Individuals withdrawing their consent.
