描述
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).

措施说明 |
大体时间 |
|---|---|---|
|
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.
大体时间：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.
