Moving Beyond the Standard Pancreatectomy for Pancreatic Adenocarcinoma

Abstract

This manuscript describes the evolution in the operative management of pancreatic cancer. Early attempts at pancreatic resection were met with daunting peri‑operative outcomes but were fine-tuned to yield today’s established pancreatic resections. Advances in medical therapy, including neo-adjuvant therapy for borderline resectable pancreatic cancers and refined adjuvant regimens, have improved oncologic outcomes and are allowing surgeons to move beyond current anatomic distinctions of resectability. Venous, hepatic artery and celiac axis resection during pancreatectomy are now common vascular operations at specialty centers which have been associated with favorable oncologic outcomes. Recent efforts are addressing locally advanced pancreatic cancer with superior mesenteric artery and/or multivessel involvement using either arterial divestment or arterial resection and reconstruction. An additional consideration in the treatment of pancreatic cancer is the benefit and risks of neoadjuvant radiation in locally advanced cases which has been avoided thus far given concerns regarding the effect of radiation on the vasculature. Therefore, with these improvements in peri‑operative therapy and robust preoperative planning often with the aid of vascular and microvascular surgeons, several centers have been exploring new frontiers in the operative management of locally advanced pancreatic adenocarcinoma.
