Study Details

Study Description

Brief Summary

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.

Condition or Disease Intervention/Treatment Phase

    Detailed Description

    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.

    Arms and Interventions

    Arm Intervention/Treatment
    Squamous cell carcinoma

    Patients included in this study will be receiving surgical treatment for their biopsy-proven squamous cell carcinoma.

    Outcome Measures

    Primary Outcome Measures

    1. Accuracy and Interrater Reliability of HRME Image Interpretation [baseline]

      We will ask blinded raters to classify the HRME images as either benign (normal) or dysplastic/cancerous (abnormal)
