  1. PanIN, pancreatic intraepithelial neoplasia; IPMN, intraductal papillary mucinous neoplasms; Ad, adenoma; Bor, borderline; Ca, carcinoma; Cy, cytoplasmic; Me, membraneous/apical; Lu, luminal.
  2. Numbers (X/Y), number of cases that expressed the marker in >10% of the cells/number of cases examined.
