Can in vivo endomicroscopy help physicians detect precancerous changes and early cancers in Barrett’s esophagus?

In Vivo Confocal Endomicroscopy for Improved Diagnosis of Barrett’s Esophagus and Associated Neoplasia: A Multicenter Randomized Controlled Trial of Diagnostic Yield and Clinical Impact

The Johns Hopkins Hospital is leading a multicenter research study to determine the best way to identify cancer in people with Barrett’s esophagus.  Gastroenterologists will compare 2 different techniques   (high resolution endoscopy (HRE) and confocal laser endomicroscopy (EM) to examine the esophagus. Endomicroscopy is a relatively new advance in endoscopic imaging, to see highly magnified pictures of the esophageal lining and better guide the places to take biopsies. .  The research study will evaluate what EM adds to high definition video endoscopy in patients undergoing routine evaluation or those with suspected pre-cancer (dysplasia) or early cancers.

Adult patients aged 18- 80 years with known Barrett’s esophagus may be eligible for this research study.  Eligible patients will be studied with HRE or HRE plus EM.  A standard of care systematic biopsy protocol will be performed in all patients, in addition to targeted sampling of suspicious areas after careful endoscopic evaluation.

This international, multicenter, double-blind randomized controlled trial will recruit a total of 200 patients over 1 year at 5 sites (Johns Hopkins in Baltimore, The Cleveland Clinic Foundation in Cleveland, Mt. Sinai Hospital in New York, Massachusetts General Hospital in Boston, and University of Mainz Germany).
