These investigations, often invasive, result in related morbidities and mor- talities, potentially offsetting the survival ben- efit from the early lung cancer detection. The International Early Lung Cancer Action Project (I-ELCAP) developed a straightforward algorithm for assessing in- determinate nodules that would provide the inclusion diagnosis of lung cancer [1]. This study protocol provides a definition for suspicious pulmonary nodules and recom- mends a diagnostic regimen to be followed once these nodules are described. The proto- col provides suggestions only; the exact de- cision for the follow-up strategies is left to the patient and physician and depends on the expertise of the institution.
