Brief Summary:
The purpose of this study is to determine biomarkers which can predict response to ablation therapy in patients with Barretts esophagus.

Condition or disease Intervention/treatment
Barrett's Esophagus Genetic: response to therapy

Detailed Description:
This Project is designed to identify biologically-based and clinically-useful biomarkers of tissue at risk for neoplastic progression as well as of response to ablation therapy. These results will result in improved risk stratification in BE and better targeting of resources for patients who are candidates for ablative therapy, while simultaneously providing key information regarding the origins of Barrett's esophagus.

Group/Cohort Intervention/treatment
Radiofrequency ablation
participants with barrett's esophagus with high grade dysplasia who undergo radiofrequency ablation (RFA)
Genetic: response to therapy
evaluate specific markers for response to therapy at specific intervals pre and post therapy

Primary Outcome Measures :
  1. Response to therapy [ Time Frame: one year post ablation ]
    evaulation will be made at 3 month intervals for one year post ablation

Biospecimen Retention:   Samples With DNA
biopsy samples, serum, plasma, buffycoat, cytology brushings
