  1. Early Lung Cancer Action project : overall design and findings from baseline screening.

    Article - En anglais

    Background The Early Lung Cancer Action Project (ELCAP) is designed to evaluate baseline and annual repeat screening by low-radiation-dose computed tomography (low-dose CT) in people at high risk of lung cancer.

    We report the baseline experience.

    Methods ELCAP has enrolled 1000 symptom-free volunteers, aged 60 years or older, with at least 10 pack-years of cigarette smoking and no previous cancer, who were medically fit to undergo thoracic surgery.

    After a structured interview and informed consent, chest radiographs and low-dose CT were done for each participant.

    The diagnostic investigation of screen-detected non-calcified pulmonary nodules was guided by ELCAP recommendations, which included short-term high-resolution CT follow-up for the smallest non-calcified nodules.

    Findings Non-calcified nodules were detected in 233 (23% [95% Cl 21-26]) participants by low-dose CT at baseline, compared with 68 (7% [5-9]) by chest radiography.

    Malignant disease was detected in 27 (2.7% [1.8-3.8]) by CT and seven (0.7% [0.3-1.3]) by chest radiography, and stage I malignant disease in 23 (2.3% [1.5-3.3]) and four (0.4% [0.1-0.9]), respectively.

    Of the 27 CT-detected cancers, 26 were resectable.

    Biopsies were done on 28 of the 233 participants with non-calcified nodules ; 27 had malignant non-calcified nodules and one had a benign nodule.

    Another three individuals underwent biopsy against the ELCAP recommendations ; all had benign non-calcified nodules. (...)
