Table 2 Anatomic staging of localized pancreatic ductal adenocarcinoma as defined by the 2008 AHPBA/SSO/SSAT consensus guidelines

	Resectable	Borderline	Locally advanced
SMV-PV	Uninvolved with tumor with clear fat planes around vessels	Abutment, encasement, or occlusion of short segment of vein	Occlusion, thrombosis, or encasement extending several centimeters
SMA	Uninvolved	Tumor abutment < 180°	Tumor abutment > 180° (encasement) or thrombosis of artery
Celiac axis	Uninvolved	Uninvolved celiac axis; short segment encasement or abutment of common hepatic artery may be amenable to resection and reconstruction	Abutment or encasement of celiac axis indicates unresectability

SMV: Superior mesenteric vein; PV: Portal vein; SMA: Superior mesenteric artery.
