Barrett's Esophagus Patients Have Same Survival Rates as General Population,
Says New Mayo Clinic Study
ROCHESTER, Minn., Oct. 26 /PRNewswire-USNewswire/ -- New Mayo Clinic research
has found that survival rates of patients with Barrett's esophagus
(http://www.mayoclinic.org/barretts-esophagus/), which can be a precursor for
esophageal cancer, are no different than the survival rates for the general
population. These findings were presented today at the 2009 American College
of Gastroenterology (http://www.acg.gi.org/) (ACG) Annual Meeting in San
Diego.

Barrett's esophagus is most often diagnosed in people who have long-term
gastroesophageal reflux disease (GERD) -- a chronic regurgitation of acid from
the stomach into the lower esophagus. A diagnosis of Barrett's esophagus can
be concerning because it increases the risk of developing esophageal cancer.
"Patients who are diagnosed with Barrett's esophagus often fear they will
develop esophageal cancer and not survive long," says Ganapathy Prasad, M.D.
(http://www.mayoclinic.org/bio/12948837.html), gastroenterologist, Mayo
Clinic, and lead author on the study. "Our research examined the survival
rates of Barrett's esophagus patients from Olmsted County, Minn., over the
past three decades, compared to a control group of patients. We wanted to
study overall survival, predictors of survival and ultimate cause of death in
patients."
In this study of 366 patients, the average patient age was 63 years, with 72
percent men and 18 percent women. All patients with a diagnosis of Barrett's
esophagus from 1977-2006 were identified using the Rochester Epidemiology
Project (http://mayoresearch.mayo.edu/mayo/research/rep/index.cfm) resources
in Olmsted County and confirmed via review of medical records. Only patients
from Olmsted County were selected to reduce referral and selection bias.
Survival data and cause of death was ascertained from medical records of the
366 patients. Overall survival at 10 years after diagnosis was 68 percent.
Causes of death included 28 percent from cardiovascular disease, 7 percent
from dementia and 7 percent from esophageal cancer. The overall survival of
this group was comparable to that of a control sample from the 2000 U.S.
census.
"Our population-based study found that Barrett's esophagus patients are at no
greater risk of dying than the rest of the population," says Dr. Prasad.
"Patients who receive this diagnosis should seek proper treatment and care,
but should also know that their odds of dying from esophageal cancer are low."
The Mayo Clinic Barrett's Esophagus Unit
(http://www.mayoclinic.org/barretts-esophagus/rsttreatment.html) offers a
multidisciplinary approach to evaluate early symptoms, devise a surveillance
schedule and perform all tests and medical and surgical treatments.
Mayo Clinic's Division of Gastroenterology and Hepatology
(http://www.mayoclinic.org/gi/) has been ranked No. 1 in the U.S. News & World
Report Honor Roll of Top Hospitals since the rankings began 20 years ago.
