Plain English Summary

Background and study aims
Esophageal cancer (adenocarcinoma; EAC) is cancer that starts in the esophagus - the food pipe that runs between the throat and the stomach. EAC is amongst the deadliest cancers, with 5-year survival rates of less than 15%. The incidence of esophageal cancer has risen rapidly over the last decades. Patients with a condition called Barrett’s Esophagus (BE) are at increased risk of developing EAC. In BE the normal lining of the esophagus changes to tissue that resembles the lining of the intestine. BE is caused by gastrointestinal acid reflux (where stomach acid travels up towards the throat). EAC develops through a stepwise process from BE to low-grade and high-grade dysplasia, and eventually to EAC. Therefore, the standard of care for Barrett’s patients consists of regular endoscopies with white-light endoscopy (WLE) and biopsies (tissues samples) to detect EAC at an early stage. When detected at an early stage, patients with EAC can be treated endoscopically with an excellent prognosis. However, EAC in BE patients is difficult to distinguish with WLE alone. Blue Light Imaging (BLI) is a new endoscopic imaging technique that uses the excitation of blue light to improve detection of EAC in BE patients. The BLI technique is incorporated in the newest FUJIFILM endoscopy systems, as well as WLE. The aim of this study is to find out whether BLI improves detection of BE before endoscopic resection (a procedure to remove the abnormal tissue).

Who can participate?
Patients aged over 18 with BE referred for endoscopy and likely to require endoscopic resection

What does the study involve?
During endoscopy, corresponding WLE and BLI endoscopic images are collected. After the procedure, these images are stored in a database and examined by six international experts.

What are the possible benefits and risks of participating?
The results of this study might in future improve endoscopy for BE patients with EAC. There are no extra risks of participation.

Where is the study run from?
1. Academic Medical Center (Netherlands)
2. Catharina Hospital Eindhoven (Netherlands)
3. University Hospital Leuven (Belgium)

When is the study starting and how long is it expected to run for?
January 2015 to January 2018

Study information

Scientific title

Blue light imaging has an additional value to white light endoscopy in visualization of early Barrett’s neoplasia: an international multicenter cohort study


BLI study

Study hypothesis

Blue Light Imaging (BLI) has additional value in overview and in magnification for the use of characterization and delineation of early neoplastic Barrett’s lesions compared to White Light Endoscopy (WLE).

Ethics approval

The Medical Research Involving Human Subjects Act did not apply to this study. Official approval of this study was therefore waived by the Medical Ethics Review Committees of all participating centers (AMC Amsterdam, Catharina Hospital Eindhoven, University Hospital Leuven)

Barrett's neoplasia


Multiple corresponding overview- and magnification WLE and BLI endoscopic images of BE neoplasia are collected. Subsequently these images are scored and delineated by six international experts using an proprietary online module.

Intervention type



Drug names

Primary outcome measure

1. Experts’ appreciation of macroscopic appearance and surface relief, measured using VAS scores in the first two assessment phases, each separated by a wash-out period of 2 weeks: Phase 1: WLE images only; Phase 2: BLI images only
2. Experts’ ability to delineate the lesion, measured using VAS scores in the first two assessment phases, each separated by a wash-out period of 2 weeks: Phase 1: WLE images only; Phase 2: BLI images only
3. Experts’ preferred technique for macroscopic appearance + surface relief and preferred technique for delineation, measured using ordinal scores in assessment phase 3 (WLE+BLI images), separated from the second assessment phase with a wash-out period of two weeks

Secondary outcome measures

Experts’ quantitative agreement on lesion delineations, measured using AND/OR scores in all three separate assessment phases, each separated by a wash-out period of 2 weeks: Phase 1: WLE images only; Phase 2: BLI images only; Phase 3: WLE+BLI images
