Endoscopic Capillary Oximetry for Tumor Diagnosis in Head and Neck Cancer
Not Recruiting
Trial ID: NCT00568360
Purpose
Endoscopy is a standard part of the evaluation of patients with head and neck cancer used for
determining the extent of tumor involvement. However, not all areas involved by tumor are
apparent visually. Preliminary results indicate that compared with normal tissues, tumors
have abnormal levels of capillary oxygenation. The purpose of this study is to determine the
ability of non-pulsatile visible light tissue oxygen monitoring to differentiate normal and
tumor tissue based on capillary oxygenation during endoscopy Should this be possible, this
method could be used to mark tumor extent and invasion, even when that invasion is up to 5mm
blow the tissue surface.
