A blood test that detects fragments of tumor DNA achieved 91% accuracy in identifying early-stage pancreatic cancer, which is notoriously difficult to catch before it spreads and has a five-year survival rate of less than 5% when diagnosed late.
Abstract
Analysis of circulating tumor DNA (ctDNA) in plasma samples from a prospective cohort of 512 individuals undergoing surgical resection for pancreatic ductal adenocarcinoma achieved 91% sensitivity and 96% specificity for stage I disease detection.
