Clonal evolutionary analysis reveals patterns of malignant transformation of Intraductal Papillary Mucinous Neoplasms of the pancreas

Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal cancer due to late detection and rapid progression. Here, the authors integrate multi-regional whole genome and RNA sequencing to characterize intratumoural heterogeneity and evolutionary trajectories underlying the malignant transformation of intraductal papillary mucinous neoplasms into invasive PDAC.
