Histopathological assessment of prognostic factors in pancreatic resection specimens using a standardised protocol

Abstract Background: Adenocarcinoma involving the pancreas shows differences in prognostic parameters including resection margin status depending on subtype. Aim: To assess the reported incidence of each type and the rate of R1 resection using detailed histopathological examination protocol. Methods: All pancreaticoduodenectomies between June 2011 and June 2013 at our institute were analysed. These were classified according to the site of origin, R1 status, size, stage at resection, lymph node status and the rate of lymphovascular and perineural invasion. Results: 58
