Near-infrared fluorescence molecular endoscopy detects dysplastic oesophageal lesions using topical and systemic tracer of vascular endothelial growth factor A

Message

The incidence of oesophageal adenocarcinoma (EAC) is steeply rising. Early lesion detection is a critical factor for improving disease prognosis. We developed and investigated wide-field near-infrared fluorescence molecular endoscopy (NIR-FME), using systemic and topical administration of a fluorescence-labelled antibody against vascular endothelial growth factor (VEGFA). Fourteen patients with Barrett's oesophagus (BE) underwent endoscopic mucosal resection (EMR) combined with NIR-MFE. From a total of 20 confirmed aberrant lesions identified with NIR-FME, 4 lesions were missed by high-definition (HD) narrowband imaging (NBI) and white-light endoscopy (WLE). This overall 25% detection enhancement advocates NIR-FME as a promising 'red-flag' technique for improving early oesophageal lesion detection. ClinicalTrials.gov ID NCT02129933.

Worldwide, >450 000 people are diagnosed with oesophageal cancer each year. In the western world, at least 80% of these cancers concern EAC.1–4 Late-stage disease detection challenges the efficacy of therapies, resulting in 400 000 deaths each year. Therefore, there...
