August 1, 2017 updated by: Prasad G. Iyer, Mayo Clinic

Utility of Aberrant Gene Methylation in the Diagnosis of Barrett's Esophagus: Identification of Candidate Diagnostic Markers

This study is to identify potential markers from esophageal biopsies and brush cytology for feasibility of use in stool specimens for detection of Barretts Esophagus.

Description

Inclusion Criteria:

Controls: No endoscopic evidence of Barrett's Esophagus, able to give informed consent, 18 years of age or older.

Cases: At least 1 cm of visible columnar epithelium with intestinal metaplasia on histology confirmed by an expert GI pathologist (on biopsy), able to give informed consent, 18 years of age or older.

Exclusion criteria:

Controls: Patients with history of esophagectomy or mucosal ablation, gastrectomy, or known non-Barrett's esophageal pathology (e.g. eosinophilic esophagitis or achalasia), varices, esophagitis LA Grade B, C, D will be excluded. Patients with prior history of colon polyps or colon/esophageal/gastric/pancreatic carcinoma (unless had negative colonoscopy within 2 years to clear polyps).

Cases: Patients with history of esophagectomy or mucosal ablation, gastrectomy, or known non-Barrett's esophageal pathology (e.g. eosinophilic esophagitis or achalasia), will be excluded. Patients with prior history of colon polyps or colon/gastric/pancreatic carcinoma (unless had negative colonoscopy within 2 years to clear polyps).

Design Details

Cohorts and Interventions

Group / Cohort
Endoscopy Barrett's
Patients undergoing clinically indicated upper endoscopy will be invited to participate. Patients who are known to have Barrett's Esophagus as well as patient who do not will be approached for enrollment
Endoscopy control
Patients undergoing clinically indicated upper endoscopy will be invited to participate. Patients who are known to have Barrett's Esophagus as well as patient who do not will be approached for enrollment

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
to determine if assay of aberrantly methylated gene markers can discriminate Barrett's Esophagus tissue (and presence of dysplasia) from esophageal squamous and gastric cardia tissue.
Time Frame: 1 day
we will plan to identify the best markers from highly selected marker candidates to differentiate between subjects who have BE and those who do not have BE.
1 day

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Assess the accuracy of candidate markers in stool for detection of Barrett's Esophagus
Time Frame: One day
Assess the ability of stool markers to distinguish between subjects who have BE and those who do not.
One day
