Genetic and Environmental Determinants of Barrett's Esophagus and Esophageal Adenocarcinoma
Case Western Reserve University
Summary
The overall objectives of this BETRNet Research Center (RC) are: 1. to conduct a rigorous, integrated spectrum of transdisciplinary human research in Barrett's esophagus (BE) and esophageal adenocarcinoma (ECA) 2. to increase the biological understanding of key observations made by our clinical researchers; 3. to translate knowledge derived from genetic, epigenetic, and transcriptome research to solving clinical dilemmas in detection, prognosis, prevention, and therapy of BE in order to prevent EAC and improve the outcomes of EAC; 4. to foster a transdisciplinary and translation research culture and to effectively expand and enhance scientific research focused on BE and EAC; 5. to evaluate research and transdisciplinary programs and to continuously improve research, productivity and enhance translational implementation. These objectives build and synergize on existing multi-institutional collaborative networks and the considerable clinical, basic science, and translational expertise available at our institutions, focusing on improving the outcomes of patients with BE and EAC. The overarching organization framework for this RC proposal is 1) to focus laboratory research on understanding the genetic susceptibility, genomic and epigenetic changes that influence the development of BE and EAC; and 2) to then translate laboratorydiscoveries into clinical applications for effective detection, molecular risk stratification, and prevention of progression from BE to EAC.
Description
This research will eventually lead to the identification of inherited genetic changes that cause Barrett's esophagus and esophageal cancer. It will help the investigators develop better methods for preventing or identifying esophageal cancer at an early curable stage. The capsule can be swallowed with a few sips water. Once the capsule is advanced to 45-50 cm from the incisors and reaches the stomach the balloon is inflated to a size of 16 mm with 5.5 cc air. It is withdrawn until a tug is felt to locate the gastroesophageal junction (GEJ). The inflated balloon is then pulled back 3 to 5 cm t…

Interventions
- DeviceBalloon Capsule Device
The Esophageal Sampling Device BESD-001 is a non-endoscopic balloon capsule catheter for obtaining an esophageal mucosal sample. At the distal end of the catheter there is a silicone capsule textured balloon assembly. The textured balloon is initially inverted with vacuum for patient to swallow the capsule but then is inflated with 5.6 cc of air (5 cc syringe withdrawn maximally) to a 16-18 mm diameter in order to contact the lumen of the esophagus to collect a sample. The balloon has a textured surface, which enhances the collection of the esophageal sample. Following sample collection the textured balloon is inverted back into the hollow capsule component via syringe draw vacuum in order to maximize \& protect the site-specific sample collection.
- ProcedureEndoscopy
An upper endoscopy is a procedure used to visually examine your upper digestive system with a tiny camera on the end of a long, flexible tube.
