Histopathologic Diagnosis

Pathologic Diagnosis	N (%)
Diagnostic results	68/78 (87.2)
Adenocarcinoma	31/78 (39.7)
Squamous cell carcinoma	15/78 (19.2)
Nonsmall-cell carcinoma NOS	10/78 (12.8)
Small cell carcinoma	3/78 (3.8)
Carcinoid	1/78 (1.3)
Renal cell carcinoma	1/78 (1.3)

Infection	6/78 (7.7)
Nondiagnostic results*	10/78 (12.8)

Percentages are listed out of 78 total number of biopsy specimens, out of 72 total patients. Two groups including: 1: diagnostic biopsy results were 68/78 (87.2): resulting in a definitive diagnosis including cancer, granuloma, or infection. Infection was seen in 6/78 (77) of the nodules biopsied (positive cultures for infections included Mycobacterium avium complex, Staphylococcus, Moraxella catarrhalis, Actinomyces.

^*2: Nondiagnostic biopsy results were 10/78 (12.8) not resulting in a definitive diagnosis and occurred in the moderate sedation cohort, including three nodules showing acute inflammation but were negative for definitive diagnosis and resolved on subsequent imaging and one patient that had fluoroscopy navigation failure.

N indicates diagnostic yield by pathologic diagnosis; NOS, not otherwise specified.
