a DECAMP-1 Schema. DECAMP-1 is recruiting 500 subjects aged 45 and older with indeterminate pulmonary nodules (0.7 to 3.0 cm) and a 20+ pack-year smoking history. Patients in this cohort have biospecimens collected at baseline and then are followed prospectively until a diagnosis of cancer or benign is made. This is the diagnostic arm of the study. b DECAMP-2 Schema. DECAMP-2 is recruiting 800 subjects aged 50–79 with a 20+ pack-year smoking history and a diagnosis of chronic obstructive pulmonary disease (COPD), emphysema or family history of lung cancer. Biospecimens from these patients are collected at baseline and annually. This constitutes the screening arm of the study
