Brief Summary:
This study will evaluate a new imaging technology, termed optical frequency domain imaging (OFDI) for detecting and diagnosing pulmonary malignancy in the central airways.

Condition or disease
Squamous Cell Lung Cancer Lung Cancer

Detailed Description:

The prevalence and high mortality rate associated with lung squamous cell carcinoma and the lack of any widely accepted screening and surveillance tools, highlights the need for new imaging paradigms that will ultimately lead to a reduction in patient mortality.

Bronchial carcinoma-in-situ will progress to invasive cancer in over 40% of individuals, and although the progression occurs over a long period of time, the majority of carcinomas are detected in the later stages of disease development, offering patients only a slim chance of cure. Although significant effort in the development of screening paradigms for the detection of lung cancer in the central airways have been made, to date there is still no widely accepted and validated approach. Optical frequency domain imaging (OFDI) is a recent derivative of optical coherence tomography (OCT). OFDI can be used to conduct volumetric microscopy of the airways at a resolution comparable with architectural histopathology. The long term goal of this study is to use OFDI to screen the airways with the hope of detecting squamous cell carcinoma at an early more curable stage.

Standard of care bronchoscopy preparation and procedures will be followed including moderate sedation, pulse oximetry and blood pressure monitoring as per department protocol. A combination of currently approved bronchoscopy techniques including standard white light bronchoscopy, autofluorescence bronchoscopy, and narrow band imaging will be used to assess the airways. Bronchial regions of interest (ROI) suspected to be premalignant or malignant, will be imaged using the OFDI system and catheter prior to biopsy acquisition. It is anticipated that a minimum of 3 OFDI-biopsy correlated pairs from each study participant will be obtained. An additional OFDI and biopsy will be obtained from a normal ROI. It is expected that the experimental procedure will add less than 10 minutes to the total length of the bronchoscopy procedure, but a stopping rule will be instituted to ensure that the experimental procedure does not exceed 20 minutes.
