Primary Outcome Measures:
  • Response to treatment [ Time Frame: at time of surveillance intervals ]
    presence of persistent or recurrence of barrett's esophagus and/or dysplasia

Biospecimen Retention:   Samples Without DNA
Esophageal Biopsy

Estimated Enrollment: 400
Study Start Date: January 2004
Estimated Study Completion Date: January 2022
Estimated Primary Completion Date: January 2020 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Patients with Barrett's Esophagus or early esophageal adenocarcinoma who will or have had ablation therapy will be enrolled in this long term follow up study
Other: Biopsy
Biopsies for research purposes will be obtained when returning for clinically indicated surveillance of Barrett's Esophagus

Detailed Description:
To assess the effect of ablation therapy on Barrett's esophagus. Proposal Ablation therapy is an FDA approved treatment to decrease cancer risk in Barrett's esophagus mucosa. This is being performed in our Barrett's Esophagus Unit on a regular basis. However, the longterm outcomes of this therapy is not established and there are patients who have been treated who later re-develop Barrett's mucosa. This study will allow us store tissue samples that can later be used to assess the effect of ablative therapy on Barrett's esophagus.
