| Am I at Risk for Esophageal Cancer? |
| There are two types of esophageal cancer: squamous cell
cancer and adenocarcinoma of the esophagus. Squamous cell cancer occurs
most commonly in people who smoke cigarettes and drink alcohol excessively.
This type of cancer is not increasing in frequency. Adenocarcinoma
of the esophagus is increasing in frequency and is associated with
gastroesophageal reflux disease (GERD). The most common symptom of
GERD is heartburn, a condition that 20 percent of American adults experience
at least twice a week. Although these individuals are at increased
risk of developing esophageal cancer, the vast majority of them will
never develop it. But in a few patients with GERD (estimates vary from
1 percent to 12 percent), a change in the esophageal lining develops,
a condition called Barren's esophagus. Doctors believe most cases of
adenocarcinoma of the esophagus begin in Barrett's tissue. |
| What is Barrett's Esophagus? |
| Barren's esophagus is a condition in which the esophageal lining
changes, becoming similar to the tissue that lines the intestine. A
complication of GERD, it is more likely to occur in patients who experienced
GERD at a young age, had nighttime symptoms or had complications such
as bleeding or stricture (a narrowing due to scarring). Dysplasia,
a precancerous change in the tissue, can develop in Barrett's tissue.
Barren's tissue is visible during endoscopy, although a diagnosis by
endoscopic appearance alone is not sufficient. The definitive diagnosis
of Barrett's esophagus requires biopsy confirmation. |
| How Does my Doctor Test or Barrett's Esophagus? |
Your doctor will first perform an upper endoscopy to diagnose
Barrett's esophagus. . Barrett's tissue has a different appearance
: than the
normal lining of the esophagus and is visible during endoscopy. Although
this examination is very accurate, your doctor will take biopsies
from the esophagus to confirm the diagnosis. Your doctor can also
use , biopsies to search for dysplasia, a pre-cancerous f^^w change
in the Barren's tissue that is not visible f fly to the endoscopist.
Taking biopsies from the / f ^cril esophagus through an endoscope
only slightly f iijr-" lengthens the procedure time, causes
no discomfort and rarely causes complications. Your doctor can usually
tell you the results of your endoscopy after the procedure, but you
will have to wait a few days for the biopsy results.

| Who Should be Screened for Barrett's Esophagus? |
Barren's esophagus is twice as common in men as women. It tends
to occur in middle-aged Caucasian men who have had heartburn for
many years. There's
no agreement among experts on who should be screened. Even in patients
with heartburn. Barren's esophagus is uncommon and esophageal cancer is
rare. One recommendation is to screen patients older than 50 who have had
significant heartburn or required regular use of medications to control
heartburn for several years. If that first screening is negative for Barren's
tissue, there is probably no need to repeat it.

| How is Barrett's Esophagus Treated? |
| Medicines and surgery can effectively control the symptoms of GERD.
However, neither medications nor surgery can reverse the presence of
Barren's esophagus or the risk of cancer. There are some experimental
treatments through which the Barrett's tissue can be destroyed through
the endoscope; but these treatments can cause complications, and their
effectiveness in preventing cancer is not clear. |
| What is Dysplasia? |
| Dysplasia is a precancerous condition that doctors can only diagnose
by examining biopsy specimens under a microscope. Doctors subdivide
the condition into high- grade, low-grade, or indefinite for dysplasia.
If dysplasia is found on your biopsy, your doctor might recommend more
frequent endoscopies, attempts to destroy the Barren's tissue, or esophageal
surgery. Your doctor will recommend an option based on the degree of
the dysplasia and your overall medical condition. |
| If I Have Barrett's Esophagus, How Often Should I Have an Endoscopy
to Check for Dysplasia? |
| The risk of esophageal
cancer in patients with Barren's esophagus is quite low, approximately 0.5
percent per year (or 1 out of 200). Therefore, the diagnosis of Barren's esophagus
should not be a reason for alarm. It is, however, a reason for periodic endoscopies.
If your initial biopsies don't show dysplasia, endoscopy with biopsy should
be repeated about every 1 to 3 years. If your biopsy shows dysplasia, your
doctor will make further recommendations. |
