First received: March 21, 2011
Last updated: June 20, 2012
Last verified: June 2012
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.

Squamous Cell Carcinoma of the Oral Cavity

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Cross-Sectional
Official Title: Ex Vivo Multimodal Imaging of Upper Aerodigestive Epithelium

Further study details as provided by Icahn School of Medicine at Mount Sinai:

Primary Outcome Measures:
  • Accuracy and Interrater Reliability of HRME Image Interpretation [ Time Frame: baseline ]
    We will ask blinded raters to classify the HRME images as either benign (normal) or dysplastic/cancerous (abnormal)

Biospecimen Retention:   Samples Without DNA
Retained specimens are punch biopsy specimens from the primary tumor resection.

Enrollment: 64
Study Start Date: June 2009
Study Completion Date: May 2012
Primary Completion Date: May 2012 (Final data collection date for primary outcome measure)
Squamous cell carcinoma
Patients included in this study will be receiving surgical treatment for their biopsy-proven squamous cell carcinoma.

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.
