Research on the treatment and prevention of esophageal cancer
is now being done at many medical centers, university hospitals, and
other institutions across the nation.
Genetics: Researchers
have found many of the changes in certain genes that appear to be
responsible for causing normal cells of the esophagus to develop into
esophageal cancer. They expect that additional progress will lead to
new tests for finding esophageal cancer at an earlier, more curable
stage. Understanding these changes will eventually lead to new gene
therapies that repair the abnormal DNA changes in esophageal cancer
cells.
Drug treatment:
Several clinical trials are in progress to test new ways to combine
drugs already known to be active against esophageal cancer to improve
their effectiveness are also being done. Other studies are testing the
best ways to combine chemotherapy with radiation therapy.
New drugs that target certain substances in the cancer cell
are becoming available. This is known as targeted therapy and
it has been successful in some other cancers. It is now being tested in
esophageal cancer.
Immunotherapy: Experimental
treatments that boost the patient's immune reaction to fight esophageal
cancer more effectively are being tested in clinical trials.
Screening and
prevention: As the rate of adenocarcinoma rises, efforts
are being made to reduce obesity, a major risk factor for this form of
cancer (and several types as well). In people with Barrett esophagus,
researchers are investigating tests to determine which patients will go
on to develop cancer. They are also studying new ways to destroy
Barrett mucosa and promote its replacement by normal mucosa. Research
also continues to find ways to stop Barrett cells from turning into
precancer or cancer.
