Biomarker Map. Bronchoscopy is performed at baseline in both DECAMP-1 and DECAMP-2 and a second time after 2 years for participants enrolled in DECAMP-2 to capture bronchial brushings and endobronchial forceps biopsies. Other specimens collected include nasal brushings, buccal scrapings, blood (fractionated into plasma and serum), urine, and sputum samples. Computed Tomography (CT) imaging is collected on all patients and used for quantitative CT imaging techniques. In patients who have a confirmed diagnosis of lung cancer and qualify as surgical candidates, fresh frozen and formalin-fixed paraffin-embedded tumor tissue is collected as well
