1. Introduction Pancreatic ductal adenocarcinoma (PDAC) has one of the highest case-specific mortality rates of all cancers [1]. Although resection remains the only curative therapy for PDAC, improvements in long-term survival are attributable to advances in systemic treatment [2,3,4,5]. Currently, 5-fluorouracil-based (i.e., with irinotecan and oxaliplatin as FOLFIRINOX) or gemcitabine-based…
