Abstract |
Background: Incomplete primary tumour excision contributes to localised post-surgical recurrence of oral squamous cell carcinoma (OSCC). The objective was to provide molecular evidence that surgical margin definition using Narrow Band Imaging (NBI) resulted in more complete OSCC excision than conventional white light (WL) panendoscopy. Methods: Molecular divergence between tumour, WL and NBI defined surgical margins was compared in 18 patients through microarray analysis (GeneChip®U133-plus-2.0). Results: The numbers of differentially expressed genes (NBI: 4387; WL: 3266; versus tumour) signified that NBI placed margins into less involved tissue than WL examination. Principal Component Analysis segregated tumour, WL and NBI tissues appropriately based solely on mRNA profiles, and unsupervised hierarchical clustering identified four patients (22%) who benefited directly from NBI surgical margin definition. Gene ontology enrichment indicated increasing cell phenotypic diversity: Tumour<WL<NBI. Conclusions: Resection to NBI defined margins will leave less dysplastic and malignant residual tissue and thereby increase ablative surgery success rates. This article is protected by copyright.
