BERLIN -- Two new blood tests can aid in the early identification of patients with gastrointestinal cancers, researchers in Belgium have found.
Dr. Joost Louwagie of OncoMethylome Sciences, a company in Liege, Belgium, said the scientists collected blood before surgery from 193 patients known to have colorectal cancer, as well as from 688 controls undergoing colonoscopy for cancer screening.
