Colorectal Cancer: Early Screening Could Save Your Life

Aug 22, 2018 | Blog

Colorectal cancer (CRC), including colon and rectum cancer, is the third most common cancer in the world and the third in the US as well. American Cancer Society (ACS) estimates that there are 97,220 and 43,030 new cases in 2018 for colon and rectum cancer, respectively. Different from some other types of cancers, death from CRC is 100% preventable if the disease is diagnosed at early stages.

The guideline from ACS for CRC screening suggest to start at age 50 (recently revised to 45). According to the statistics from the U.S. Centers for Disease Control and Prevention (CDC), 66.2% of the U.S. population from age 50 to 75 did CRC screening in 2014 and this number grew to 67.3% in 2016, representing increase of 3.3 million people for the testing.

CRC screening and diagnosis can be done either through stool test or visual exams of colon and rectum. A recent new stool test, ColoGuard®, approved by the FDA in 2014, is a molecular test for gene mutations and modifications (methylation). Different than the gold standard, colonoscopy, molecular diagnostic testing does not need tedious and even intimidating preparation before the test, and not to worry about possible bleeding and infection due to medical complication.

We recently developed ColoScape™ CRC mutation detection kit using our proprietary XNA technology. The feature of the detection kit:

  • Is in the research use only (RUO) or CE/IVD-mark format.
  • Identifies mutations commonly occurred in CRC using qPCR instruments commonly available.
  • Uses liquid biopsy (blood) or Formalin-Fixed Paraffin-Embedded (FFPE) samples, rather than stool samples, which need complex DNA extraction procedure in centralized labs.
  • Has a detection limit as low as 0.1% of tumor DNA among the normal cell DNA.

Who should be tested for VEXAS syndrome?

As a relatively newly discovered autoinflammatory disease, VEXAS (Vacuoles, E1 enzyme, X-linked, Autoinflammatory, Somatic) syndrome is associated with mutations in the UBA1 gene. Diagnosis of the disease relies on the testing of genetic mutation in patients. What are...

Genetic Testing for the VEXAS Syndrome

Diagnosis of the VEXAS syndrome improves medical management of the disease and provides more effective treatment of the disease, although there is no cure currently. The diagnosis relies on the VEXAS syndrome genetic testing, a test for a mutation present in the UBA1...

What is VEXAS syndrome?

VEXAS syndrome, which stands for "Vacuoles, E1 enzyme, X-linked, Autoinflammatory, Somatic," is a rare and recently identified, chronically progressive autoinflammatory disorder. It was first described by Dr. Beck in a study published in the New England Journal of...
