WASHINGTON, D.C. – A group of researchers from Mayo Clinic and Exact Sciences Corporation have completed a phase II study comparing a set of DNA markers to alpha fetoprotein as a method to test for liver cancer. The researchers presented their findings today at the 2018 Digestive Disease Week conference in Washington, D.C.
“We currently test for liver cancer using ultrasound and a blood protein marker called alpha fetoprotein,” says John Kisiel, M.D., a gastroenterologist at Mayo Clinic. “Unfortunately, these tests are not very sensitive for curable stage liver cancers, and most patients who need this testing do not have it easily available or [are] not able to receive it often enough to be effective.”
Dr. Kisiel and his colleagues developed a simple blood test using abnormal DNA markers that are known to exist in liver cancer tissues. They were able to confirm that the abnormal DNA markers were present in the overwhelming majority of blood samples that came from people with primary liver cancers. Simultaneously, these markers were absent in healthy individuals and individuals with cirrhosis of the liver but no evidence of tumors on their clinical follow-up.
“We were most excited that our DNA markers were able
