- Urinary deuterated phenanthrene tetraol level [ Time Frame: Up to 6 hours ]A multiple regression analysis will be performed including explanatory variables such as lesion status, presence/absence of chronic obstructive pulmonary disease (COPD) or asbestos, duration of smoking, smoking intensity, age, and gender.
- PheT:HOPhe ratio [ Time Frame: Up to 6 hours ]A multiple regression analysis will be performed including explanatory variables such as lesion status, presence/absence of COPD or asbestos, duration of smoking, smoking intensity, age, and gender.
- Correlation of deuterated phenanthrene tetraol level and PheT:HOPhe ratio with the presence of bronchoepithelial metaplasia and/or dysplasia [ Time Frame: Up to 6 hours ]A multiple regression analysis will be performed including explanatory variables such as lesion status, presence/absence of COPD or asbestos, duration of smoking, smoking intensity, age, and gender.

Experimental: Basic Science (deuterated phenanthrene tetraol)
Patients receive deuterated phenanthrene tetraol PO and collect urine for 6 hours after dosing.
Radiation: deuterated phenanthrene tetraol

I. To determine the relationship between urinary deuterated ([D10]) phenanthrene tetraol (PheT) level, PheT:phenanthrols (HOPhe) ratio, and the presence of bronchoepithelial metaplasia and/or dysplasia in smokers who have undergone screening bronchoscopy at Roswell Park Cancer Institute (RPCI).
Patients receive deuterated phenanthrene tetraol orally (PO). Urine samples are collected for laboratory studies for 6 hours after dosing.
