Colon
Polyp Prevention Study
Colon
cancer is the third most common cancer that affects
men and women in the United States. Among the tumors that
affect humans, colon cancer is unique because it is usually
preceded by a clearly identifiable, asymptomatic precursor
growth known as an adenomatous polyp. Identification and
removal of these pre-malignant polyps can prevent the development
of colon cancer. This is the rationale for using endoscopy
to identify and remove colonic polyps. That said, it would
be useful if medications were developed that inhibit the
formation of colorectal polyps. This is the basis for the
Adenoma Prevention with Celecoxib (APC) trial.
Epidemiologic
studies suggest that individuals who regularly use aspirin
and other non-steroidal anti-inflammatory drugs (NSAIDs)
are at reduced risk of developing colonic polyps and cancer.
However, long-term use of these drugs is associated with
complications that include peptic ulcer disease. Recently,
selective COX-2 inhibitors have been developed. Celecoxib
is more selective in its mechanism of action than aspirin
or other NSAIDs. Celecoxib may be safer than traditional
NSAIDs although this remains to be proven.
Celecoxib
protects against colorectal tumors in experimental animals.
Treatment with celecoxib also reduced the colorectal polyp
burden in patients with a genetic condition known as Familial
Adenomatous Polyposis (FAP). As a result of this human study,
celecoxib was approved by the FDA as adjunctive therapy
in patients with FAP. The goal of the current trial is to
determine whether celecoxib can prevent the recurrence of
sporadic colorectal adenomas.
If
you have had an adenomatous polyp of the colon/rectum removed
during the past 24 weeks and are potentially interested
in participating in this study, please contact:
