Colorectal Cancer
Colorectal cancer kills 57,000 Americans each year, and
is the second leading cause of cancer-related deaths in this
country. According to the report published by American Cancer
Society (ACS), an estimated 146,000 new colorectal cancer
cases will be diagnosed yearly in the United States.
The ACS estimates that by detecting and treating early-stage colorectal
cancer can reduce the mortality rate by as much as 90%.
The underlying idea behind screening is that unlike many
other types of cancer, colon cancer is easily curable if found
early and also can be prevented by removing precancerous precursors
(polyps). Both polyps and early-stage cancers are usually
asymptomatic. Compared with these lesions, cancers that have
grown large enough to cause symptoms have a much worse prognosis.
This contrast highlights the need for screening in asymptomatic
persons.
Fecal Occult Blood Test (FOBT) is the most commonly used
method for initial screening of colorectal cancer. However,
the conventional chemical test methods such as Guaiac test
are not specific in detecting human occult blood. In order
to get more accurate test results, it requires that certain
foods, drugs, vitamins and many other substances be avoided
3-7 days before testing. In spite of this, pseudo-positive
result remains as high as 30%.
In addition, a major drawback to Guaiac based fecal occult
blood testing as a screening technique is poor compliance.
Only about 38 percent of patients in the large trials completed
all planned tests. The complexity includes patient preparation,
inconvenience, facilities and equipment needed, and patient
discomfort.
Hemosure®, an one-step, easy to use product
developed by Hemosure, Inc. based on its years of
clinical
study, is the latest technological breakthrough in Immunological
Fecal Occult Blood Testing (IFOBT), and it is both
FDA approved and CLIA waived.
Hemosure®
employs a unique combination of monoclonal and polyclonal
antibodies to detect only human blood in stool. As a result,
abstinence of food and drug before taking this test is no
longer necessary. These advantages can significantly enhance
patient compliances.
In addition to the inherent specificity and sensitivity,
Hemosure® test can be performed by
health care providers in hospitals, labs and private practices.
No need to send fecal samples to the laboratory. Doctors can
easily, quickly and accurately read the test results in less
than 5 minutes. This new technology has greatly improved specificity,
sensitivity, accuracy and cost-effectiveness of the fecal
occult blood tests.
Hemosure® has unquestionably
set a new standard on how future fecal occult blood testing
is carried out.
