PHILADELPHIA — A team of Mayo Clinic researchers has succeeded in identifying the source of cancer in patients’ gastrointestinal tracts by analyzing DNA markers from tumors. The results open the possibility that doctors could one day be able to screen for cancer anywhere in the body with a noninvasive blood test or stool sample. Such tests, if they prove practical and feasible, could mean greater convenience for patients and saved lives through earlier diagnosis of cancer, especially rare and often lethal diseases such as pancreatic cancer or lung cancer.
The researchers' findings will be presented on April 21 in a poster presentation at the AACR Annual Meeting 2015 in Philadelphia by John Kisiel, M.D., a gastroenterologist at Mayo Clinic.
