This trial is a multi-center clinical and endoscopic outcomes project involving a single large database of patients with Barrett's Esophagus (BE). The initial goal of this project is to define the incidence and prevalence of cancer and high-grade dysplasia (HGD) in patients with BE. Thus, our hypothesis is that systematic collection of data on the natural history of BE and risk factors for progression of BE will provide useful information to develop a decision model for risk stratification and risk reduction strategies in BE.

Further study details as provided by PRATEEK SHARMA, Midwest Biomedical Research Foundation:

Primary Outcome Measures:
  • To determine the prevalence and incidence of low grade dysplasia, high grade dysplasia and adenocarcinoma in a large cohort of patients with Barrett's esophagus [ Time Frame: up to 10 years ]

Secondary Outcome Measures:
  • To determine the magnitude of the contribution of selected factors (e.g. age, gender, ethnicity, obesity, tobacco use, alcohol use, ASA/NSAID/PPI use, duration of GERD symptoms, length of BE, HH) to the risk of HGD and CA [ Time Frame: up to 10 years ]

Enrollment: 1250
Actual Study Start Date: November 2007
Study Completion Date: May 2017
Primary Completion Date: May 2017 (Final data collection date for primary outcome measure)
Patients with confirmed Barrett's Esophagus

  Show Detailed Description


Ages Eligible for Study:   18 Years to 80 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Sampling Method:   Probability Sample
Study Population
Patients who have histologically confirmed Barrett's Esophagus

Inclusion Criteria:

  • Sex: Male and female
  • Age: 18-80 years
  • Confirmed BE.

Exclusion Criteria:

  • Columnar mucosa in the distal esophagus but no intestinal metaplasia on biopsy.
  • Patients with BE who have undergone endoscopic ablation therapy or enrolled in chemoprevention trials. Since this is a natural history study, patients enrolled in intervention trials (e.g. those undergoing endoscopic ablation of their BE) will be excluded.
