Objective: Ampullary neoplastic lesions can be resected by endoscopic papillectomy (EP) or transduodenal surgical ampullectomy (TSA) while pancreaticoduodenectomy is reserved for more advanced lesions. We present the largest retrospective comparative study analysing EP and TSA.
Design: Of all patients in the database, lesions with prior interventions, benign histology advanced malignancy (T2 and more), patients with hereditary syndromes and those undergoing pancreatoduodenectomy were excluded.

Background: Pathologic complete response after neoadjuvant treatment in pancreatic ductal adenocarcinoma is a rare occurrence. Similar to other malignancies, achieving a pathologic complete response in pancreatic ductal adenocarcinoma seems to correlate with improved survival. However, because of the rarity of such events, the true significance of pathologic complete response in pancreatic cancer remains unclear.

Its impact on nodal-positive resected pancreatic ductal adenocarcinoma patients is unclear. The aim of this study was to analyse the effect of margin clearance on survival among resected, nodal-positive pancreatic ductal adenocarcinoma patients whose specimens were analysed according to the Leeds Pathology Protocol.

Objectives: To develop a futility risk model using a multi-institutional database and provide unified criteria associated with a futility likelihood below a safety threshold of 20%.
Design, Setting, And Participants: This retrospective study took place from January 2010 through December 2021 at 5 high- or very high-volume centers in Italy.
