The Lung PCA: A Multi-Dimensional Atlas of Pulmonary Premalignancy

"Bronchoscopy: Your nose, throat, vocal cords and windpipe are sprayed with Lidocaine (numbing medicine) to help keep you from coughing and to numb your airways. A tube with either a white light or the fluorescent light (bronchoscopy) is put down through your nose or mouth into your throat. Your nose, throat, vocal cords and lungs will be checked for any unusual areas while the tube goes down. You might have medicine sprayed into your mouth. You may be given a shot into your vein or muscle to help you be more comfortable.~Endobronchial Biopsy: Very tiny pieces of lung tissue (about the size of the head of a pin) will be taken from the lining of your lungs using forceps and a small brush. These tissues will be taken to a laboratory and tested."

Subjects will be asked to perform the early morning spontaneous cough technique over a six-day period to provide for pre-screening evaluations. If moderate atypia is detected in a pre-screening specimen, additional sputum samples will be collected prior to each subsequent bronchoscopy. If this cannot be performed prior to bronchoscopy with adequate results, the sputum collection may be done after bronchoscopy. The sputum will be collected in containers containing Saccomanno's fixative.

Thirty milliliters of blood will be withdrawn from each subject, and the blood will be sent to the biorepository for analysis and storage.
