Brief Summary
Purpose: Patients with peripheral lung nodules require evaluation for lung cancer. Our aim is to assess the diagnostic yield of a new technique, transbronchial cryobiopsies, in patients at risk for lung cancer. Target population: Patients referred for bronchoscopy and lung biopsies as a part of their work up for peripheral lung lesions. Procedures: Patients enrolled will have forceps transbronchial biopsies followed by transbronchial cryobiopsies for their lung lesion during bronchoscopy.

Outcome Measures
Primary Outcomes (1)
The increase in sensitivity for diagnosing lung cancer with the addition of cryobiopsy to standard forceps biopsy for a suspicious lung nodule.
Sensitivity for cancer is defined as true positives / (true positives + false negatives) with respect to diagnosing malignancy. If the bronchoscopic procedure fails to diagnose malignancy, the gold standard will be the results of any further, more invasive testing that is clinically indicated to evaluate the nodule.
1 year
Secondary Outcomes (2)
The increase in sensitivity for diagnosing a specific benign lung disease with the addition of cryobiopsy to standard forceps biopsy for a suspicious lung nodule.
1 year
The number of participants with pneumothorax or significant bleeding related to the addition of transbronchial cryobiopsy to standard forceps biopsy.
1 year
Study Arms (1)
Single intervention arm - transbronchial biopsy
EXPERIMENTALPatients enrolled in this single arm study will have lung nodules biopsied by traditional forceps followed by transbronchial cryobiopsy
