-- Exact Sciences (Nasdaq: EXAS) today presented data showing that its non-invasive CologuardTM stool-based (sDNA) screening test detected 64 percent of colorectal pre-cancers and 85 percent of cancers. The study was conducted in collaboration with Mayo Clinic and examined more than 1,100 patient samples. Results were presented at the 2010 Special Conference for Colorectal Cancer: Biology to Therapy held by the American Association for Cancer Research in Philadelphia, PA.
Colorectal cancer is the second leading cancer killer in the United States. It often is considered the most preventable, yet least prevented cancer. Colorectal cancer is highly treatable if found early, but 40 percent of adults age 50 and older have not been screened as recommended.
"This is the first study of an sDNA test to show such promising results in detecting colorectal pre-cancer," said lead investigator David A. Ahlquist, M.D., Mayo Clinic, Rochester, Minn. "Colorectal cancer is a treatable disease if caught early, and this test shows great promise as a potential addition to other available screening tools."
