Description…

CDH13 is a member of the cadherin superfamily. The encoded protein is a calcium dependent cell-cell adhesion glycoprotein comprised of five extracellular cadherin repeats, a transmembrane region but, unlike the typical cadherin superfamily member, lacks the highly conserved cytoplasmic region. This particular cadherin is a putative mediator of cell-cell interaction in the heart and may act as a negative regulator of neural cell growth. The gene locus is hypermethylated or deleted in breast, ovarian and lung cancers.

Esophagus

Attributes

Phase: Two
QA State: Accepted

Overview

Esophageal adenocarcinoma risk in Barrett's esophagus is increased 30- to 125- fold versus the general population. Among all Barrett's esophagus patients neoplastic progression occurs only once per 200 patient-years. Molecular markers (individual or in panel) would be useful to risk-stratify patients for more efficient surveillance endoscopy and to improve the early detection of progression.

Performance Comment

Levels of CDH13 hypermethylation have been shown to discriminate esophageal adenocarcinoma from esophageal squamous cell carcinoma and normal esophagus. CDH13 is also being investigated as a biomarker for progression from Barrett's esophagus to esophageal adenocarcinoma. Studies are ongoing.

Barrett's Esophagus Methylation Profiles

We propose a nested case-control study of biomarkers in the setting of BE. By bringing together research institutions with large populations of patients with BE, we will perform a multi-center study of FISH and hypermethylation markers as possible prognostic factors in BE. The centers will select from their cohorts who have progressed to HGD or to adenocarcinoma of the esophagus ("progressors"), and who also donated samples prior to the development of cancer, when their histology was felt to be benign. These subjects will be compared to individuals who have been under endoscopic surveillance, but who have not progressed to HGD or EAC ("non-progressors"). Using this approach, we hope to identify promising markers for risk stratification in BE. We expect to be able to make successful application for a prospective study of markers identified in this case-control study.
