Which of the following is not a risk factor for carcinoma of the esophagus?
Chronic alcohol use
H. pylori infection
Chronic GERD
Plummer Vinson syndrome
Barrett esophagus develops in patients with chronic GERD and represents columnar metaplasia of the esophageal squamous mucosa. Barrett esophagus is a risk factor for development of esophageal adenocarcinoma. Esophageal squamous cell carcinoma is associated with alcohol and tobacco use, povey, caustic esophageal injury, achalasia, tylosis, and Plummer-Vinson syndrome. Some serotypes of Helicobacter pylori are associated with decreased risk of esophageal adenocarcinoma. Helicobacter pylori infection can be a risk factor for development of MALT lymphoma in stomach.
