R1 resection in pancreatic cancer has significant impact on long-term outcome in standardized pathology modified for routine use

Background The quality of a histopathologic workup after oncologic resection of pancreatic malignancies has changed the central role of surgery substantially for radical tumor clearance over the past years. The development of standardized protocols for pathologic workup increased the rate of R1 resections from around 20% up to 80%. In the present study, we investigated the incidence of R1 and its impact on survival after oncologic pancreatic...
