Table 1 Criteria used for determining resectability for non-metastatic pancreatic cancer

From: A retrospective study of neoadjuvant FOLFIRINOX in unresectable or borderline-resectable locally advanced pancreatic adenocarcinoma

Category Criteria§
Resectable · No evidence of SMV and portal vein abutment, distortion, tumor thrombus or venous encasement
  · Clear fat planes around the celiac axis, hepatic artery and SMA
Borderline resectable · Venous involvement of the SMV/portal vein demonstrating tumor abutment with or without impingement and narrowing of the lumen, encasement of the SMV/portal vein but without encasement of the nearby arteries, or short segment venous occlusion resulting from either tumor thrombus or encasement but with suitable vessel proximal and distal to the area of vessel involvement, allowing for safe resection and reconstruction.
  · Gastroduodenal artery encasement up to the hepatic artery with either short segment encasement or direct abutment of the hepatic artery, without extension to the celiac axis
  · Tumor abutment of the SMA not to exceed 180 degrees of the circumference of the vessel wall
Unresectable · Major venous thrombosis of the portal vein or SMV extending for several centimeters
  · Circumferential encasement of the SMA, celiac axis or proximal hepatic artery
  1. Abbreviations: SMA: Superior mesenteric artery; SMV: Superior mesenteric vein.
