Esophageal cancer risk lower than expected for patients with GERD
Date:12/9/2010

ANN ARBOR, Mich. The risk of esophageal cancer among patients who suffer from gastroesophageal reflux disease (GERD) is not as high as many may think, according to new research from University of Michigan gastroenterologists.

GERD is considered a relative risk for developing esophageal adenocarcinoma, but the absolute risk is not known, says Joel Rubenstein, M.D., M.Sc., an investigator with the Department of Veterans Affairs Center for Clinical Management Research in Ann Arbor and Assistant Professor in the University of Michigan's Department of Internal Medicine.

"Since GERD is incredibly common, many people may be worried about their increased risk for developing cancer due to GERD. This study's results help put that risk into perspective and may help physicians decide when screening to prevent cancer is needed," says Rubenstein.

Rubenstein and his co-authors set out to estimate the incidence of new cases of esophageal adenocarcinoma in the large population of people with GERD symptoms.

The research published in the American Journal of Gastroenterology this week found:

  • Women with GERD likely have a low rate of esophageal adenocarcinoma, similar to the rate of breast cancer in men.
  • The rate of esophageal adenocarcinoma in white men who are 60 years old with weekly GERD is just one-third of their rate of colorectal cancer or 34.6 per 100,000 patients per year.
  • The rate of esophageal adenocarcinoma in younger white men with GERD is less than one-third of their incidence of colorectal cancer.

GERD is characterized by symptoms that result from repeated or prolonged exposure of the lining of the esophagus to acidic contents from the stomach and occurs when the lower esophageal sphincter does not seal off the esophagus from the stomach.

The two most frequently reported symptoms of GERD are heartburn and regurgitation, which is characterized by the effortless flow of fluid rising up the che
