DECAMP-1: Diagnosis and Surveillance of Indeterminate Pulmonary Nodules

Status: complete

The goal is to improve the efficiency of the diagnostic follow-up of patients with indeterminate pulmonary nodules by determining whether biomarkers for lung cancer diagnosis that are measured in minimally invasive biospecimens are able to distinguish malignant from benign pulmonary nodules that are incidentally detected in high-risk smokers.

Inclusion Criteria

45 years of age or older;
Initial diagnosis of indeterminate pulmonary nodule (0.7-3.0 cm);
Smoking status: Current or former smoker with ≥ 20 pack years (pack years = number of packs per day X number of years smoked)
Willing to undergo fiberoptic bronchoscopy;
Able to tolerate all biospecimen collection as required by protocol;
Able to comply with standard of care follow up visits including clinical exams, diagnostic work-ups, and imaging for a minimum of two years;
Able to fill out Patient Lung History questionnaire;
Willing and able to provide a written informed consent.

Exclusion Criteria

History or previous diagnosis of lung cancer;
Diagnosis of pure ground glass opacities on chest CT;
Contraindications to nasal brushing or fiberoptic bronchoscopy including ulcerative nasal disease, hemodynamic instability, severe obstructive airway disease, unstable cardiac or pulmonary disease; inability to protect airway or altered level of consciousness;
Allergies to any local anesthetic that may be used to obtain biosamples in the study.

The Detection of Early lung Cancer Among Military Personnel (DECAMP) consortium is a

multidisciplinary and translational research program that includes 7 Veterans

Administration Hospitals (VAH), the 4 designated Military Treatment Facilities (MTF) and

4 academic hospitals as clinical study sites, several molecular biomarker laboratories,

along with Biostatics, Bioinformatics, Pathology and Biorepository cores. The DECAMP

Coordinating Center will facilitate rapid selection, design and execution of clinical

studies within this multi-institutional consortium. The goal will be accomplished by

recruiting 500 smokers with indeterminate pulmonary nodules (0.7cm - 3.0cm) on chest CT

who will undergo fiberoptic bronchoscopy and will be followed for 2 years until a final

diagnosis is made. The diagnostic performance of four previously established lung cancer

biomarkers in this cohort will be validated; 1) a gene-expression biomarker measured in

bronchial airway brushings; 2) a proteomic signatures measured in bronchial airway

biopsies; 3) a proteomic signature measured in serum; and 4) a signature of serum

cytokines. The added value of the molecular markers to clinical and imaging markers

routinely used in the diagnostic work up of these patients and develop an integrated

model (i.e. clinical, imaging & molecular markers) that results in the most robust

diagnostic predictor will be evaluated.
