简要总结
RATIONALE: Learning about how often heartburn and other risk factors occur in brothers and sisters and other family members of patients with Barrett's esophagus may help identify other individuals at risk and identify genes for Barrett's esophagus.
PURPOSE: This clinical trial is studying genes for Barrett's esophagus in brothers and sisters.
详细描述
OBJECTIVES:
Primary
- To investigate the familial incidence of heartburn and Barrett's esophagus in first and second degree relatives of patients with Barrett's esophagus in the United Kingdom.
- To determine susceptibility genes for Barrett's esophagus in affected sibling pairs.
- To examine gene-environment interactions, such as smoking, alcohol, and Helicobacter pylori status, on familial susceptibility to heartburn and Barrett's esophagus.
Secondary
- To compare the mortality from esophageal adenocarcinoma in family members with heartburn and Barrett's esophagus with deaths from other causes.
