Chairside molecular imaging of aberrant glycosylation in subjects with suspicious oral lesions using fluorescently labeled wheat germ agglutinin

Abstract

Background

Aberrant sialylation is accepted as a carcinogenic biomarker. In previous work, fluorescently labeled wheat germ agglutinin (WGA) distinguished between cancerous and normal oral biopsies. The purpose of this study was to investigate WGA-fluorescein isothiocyanate (FITC) as a point-of-care tool for detecting oral malignant and dysplastic lesions in vivo.

Methods

Subject recruitment was divided into two groups: (1) the clinically normal oral mucosa group; or (2) the presence of clinically suspicious oral lesion(s) group. A WGA-FITC solution was topically applied to observable lesions or to half the subject's mouth (sagittal plane) if lesions were absent. Fluorescent molecular imaging was used to evaluate WGA-FITC localization.

Results

Fluorescent imaging in 55 subjects demonstrated that WGA-FITC could detect histopathologically-confirmed cancerous and dysplastic lesions with high sensitivity (100% and 81%, respectively) and specificity (82%).

Conclusion

This study supports in vivo fluorescent molecular imaging of WGA-FITC to visualize aberrant sialic acid expression associated with carcinogenesis. This technique resulted in the immediate chairside detection of oral cancerous and dysplastic lesions.
