Detailed Description
This study is to identify potential biomarkers for the early detection of Barrett's Esophagus, esophageal carcinoma (both adenocarcinoma and squamous cell carcinoma). Esophageal and gastric cytology will be collected via sponge capsule. Candidate genes will be tested with DNA isolated from these samples in order to identify optimal biomarkers to differentiate between Barrett's esophagus and esophageal/gastric cancer versus normal esophageal/gastric tissue.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Control Patients age 18 or greater who have undergone esophagogastroduodenoscopy and does not have a diagnosis of Barrett's esophagus or esophageal/gastric malignancy. |
|
| Barrett's esophagus Patients age 18 or greater who have undergone esophagogastroduodenoscopy and diagnosed with Barrett's esophagus via pathology. |
|
| Esophageal carcinoma Patients age 18 or greater who have diagnosis of primary esophageal carcinoma. |
|
| Gastric cancer Patients age 18 or greater who have diagnosis of primary esophageal cancer. |
Outcome Measures
Primary Outcome Measures
- Difference in methylation of gene markers to discriminate Barrett's esophagus from non-pathological esophageal squamous and gastric cardia tissue. [1 day]
Using DNA methylation, we plan on identifying, from a pool of highly selected marker candidates, the best biomarkers that are aberrantly methylated in Barrett's esophagus versus control in order to differentiate between subjects who have Barrett's esophagus and those who do not have Barrett's esophagus. This is measure using methylation index and the calculated probability score from different methylation index values.

- Difference in methylation of gene markers to discriminate gastric cancer from non-pathological esophageal squamous and gastric cardia tissue. [1 day]
