Direct Visual Fluorescence in Finding Oral Cancer in High-Risk Patients and Patients Undergoing Routine Dental Care

Not Applicable

Completed

• Conditions: Tongue Cancer; Oral Cavity Verrucous Carcinoma; Stage 0 Lip and Oral Cavity Cancer; Lip and Oral Cavity Squamous Cell Carcinoma

• Registration Number: NCT01816841
• Lead Sponsor: Ohio State University Comprehensive Cancer Center

Brief Summary

This clinical trial studies direct visual fluorescence in finding oral cancer in high-risk patients and patients undergoing routine dental care. Diagnostic procedures, such as direct visual fluorescence, may help find and diagnose oral cancer.

Detailed Description

PRIMARY OBJECTIVES:

I. To assess the diagnostic benefit of the VELscope (direct visual fluorescence) inspection in oral examination.

II. Efficacy of the VELscope in identifying dysplastic (premalignant) and malignant oral mucosal lesions and in discriminating these lesions from common benign tissue changes.

III. Accuracy of clinical judgment versus VELscope findings. IV. Ability of the VELscope to identify lesions or extent of lesions beyond what is clinically apparent.

OUTLINE:

Patients undergo conventional oral examination (COE) followed by direct visual fluorescence examination (DVFE). Patients with tissue abnormalities found by COE or DVFE undergo scalpel biopsy within 2 weeks.

Inclusion Criteria

• HIGH-RISK POPULATION:
• 33 consecutive consenting patients presenting to The Ohio State University James Cancer Hospital Otolaryngology Department with a suspicious oral lesion or prior biopsy-confirmed epithelial dysplasia (mild, moderate, severe), carcinoma in situ (CIS), or squamous cell carcinoma (SCC) will be recruited; adult patients presenting for initial evaluation for treatment planning and/or presenting for follow-up appointments monitoring for recurrence will be eligible to participate
• GENERAL POPULATION:
• 250 consecutive consenting patients presenting to The Ohio State University College of Dentistry for routing dental care will be recruited; adult patients presenting to the screening clinic for initial oral evaluation will be eligible to participate

Primary Outcome Measures

Name	Time	Method
Sensitivity and specificity of DVFE compared to visual inspection by conventional oral examination alone	At the time of examination	Will be evaluated by calculating sensitivity and specificity and their corresponding exact 95% confidence intervals. Association between the two techniques will be assessed using the simple kappa statistic.
Differences between lesional margins identified by COE and DVFE	At the time of examination	Will be evaluated using the dependent t-test. In the event that the parametric requirements of this test are not met, the Wilcoxon, matched-pairs, signed-ranks test will be used.
