Esophageal cancer is a cancerous
(malignant) tumor of the esophagus, the muscular tube that moves
food from the mouth to the stomach.
·
Backwards movement of food through the
esophagus and possibly mouth (regurgitation)
·
Chest pain unrelated to eating
·
Difficulty swallowing solids or liquids
·
Heartburn
·
Vomiting blood
·
Weight loss
When esophageal cancer is only in the
esophagus and has not spread, surgery is the treatment of
choice. The goal of surgery is to remove the cancer.

Esophagectomy - minimally invasive
Sometimes chemotherapy, radiation, or
a combination of the two may be used instead of surgery, or to
make surgery easier to perform.
If the patient cannot tolerate
surgery or the cancer has spread to other organs, chemotherapy
or radiation may be used to help reduce symptoms. This is called
palliative therapy. In such cases, the disease is usually not
curable.
Other treatments that may be used to
improve a patient's ability to swallow include endoscopic
dilation of the esophagus (sometimes with placement of a stent
to keep the esophagus dilated), or photodynamic therapy. In
photodynamic therapy, a special drug is injected into the tumor,
which is then exposed to light. The light activates the medicine
that attacks the tumor.
Esophageal cancer is relatively
uncommon in the United States. It occurs most often in men over
50 years old. Two main types of esophageal cancer exist:
squamous cell carcinoma and adenocarcinoma. These two types look
different from each other under the microscope.
Squamous cell esophageal cancer is
associated with smoking and alcohol consumption.
Barrett's esophagus, a complication
of gastroesophageal reflux disease (GERD), significantly
increases the risk for adenocarcinoma of the esophagus. Other
risk factors for adenocarcinoma of the esophagus include:
·
Alcohol use
·
Male gender
·
Obesity
·
Poor nutrition
·
Smoking
Tests used to help diagnose
esophageal cancer may include:
·
Barium swallow
·
Esophagogastroduodenoscopy (EGD) and
biopsy
·
Chest MRI or thoracic CT (usually used to
help determine the stage of the disease)
·
PET scan (sometimes useful for
determining the stage of disease, and whether surgery is
possible)
·
Endoscopic ultrasound (used to determine the stage of disease)
Stool testing may show small amounts
of (occult) blood in the stool.
Esophageal cancer is a very difficult
disease to cure. When the cancer has not spread outside the
esophagus, surgery may improve chances of survival.
Radiation therapy is used instead of
surgery in some cases where the cancer has not spread outside
the esophagus.
For patients whose cancer has spread,
cure is generally not possible and treatment is directed toward
relieving symptoms.
The following may help reduce your
risk of squamous cell cancer of the esophagus:
·
Avoid smoking
·
Limit or eliminate alcoholic drinks
People with symptoms of severe
gastroesophageal reflux should seek medical attention.
Screening with EGD and biopsy in
people with Barrett's esophagus may lead to early detection and
improved survival. People who are diagnosed with Barrett's
esophagus should be checked regularly for esophageal cancer.
