The purpose of this research study is to collect information on whether images made using
investigational microscopes can improve researchers' ability to evaluate and distinguish
between normal and abnormal areas in tissue samples surgically removed from patients with
squamous cell carcinoma. The microscopes being used in this study are considered
investigational because they have not been approved by the United States Food and Drug
Administration (FDA) for finding abnormal or pre-cancerous areas.
The overall objective of this exploratory study is to evaluate whether noninvasive
fluorescence and reflectance imaging of the upper aerodigestive tract can help clinicians
more accurately determine intraoperative margins during ablative cancer surgery. This is an
ex vivo study designed to evaluate the feasibility of using prototype optical imaging
technology to enhance the discrimination between areas of noncancerous "normal" and
cancerous mucosa. The results of this laboratory study will be used to further refine and
develop this technology for in vivo application.
Primary Aim:
(1) To collect data to develop imaging algorithms to distinguish between normal and
cancerous upper aerodigestive mucosa.
Secondary Aims:
1. To compare the combination of wide-field fluorescence/reflectance and high resolution
fluorescence microscopy images of upper aerodigestive epithelium to histopathologic
analysis of biopsied tissue.
2. To compare the ability of sequential wide-field/fluorescence microscopy imaging to
discriminate between normal and cancerous oral cavity mucosa with that of white-light
images obtained after staining with toluidine blue.
