Resectability criteria

Resectability status		Resectable	Borderline resectable	Locally advanced
Arterial involvement	Celiac artery	None	≤ 180°; > 180°, without involvement of aorta o GDA (body/tail)	>180° (head/uncinate); Solid tumor contact with CA and aorta
	SMA common hepatic artery	None	≤ 180°; Solit tumor contact without extension into CA or hepatic artery biforcation	> 180°
Venous involvement (portal vein/smv)		None; ≤ 180° contact without contour irregularity	> 180°; ≤ 180° with contour irregularity or thrombosis, with reconstructible PV/SMV; Solid tumor contact with IVC	Unreconstractible PV/SMV due to tumor involvement or occlusion

CA: Celiac artery; GDA: Gastroduodenal artery; IVC: Inferior vena cava; PV: Portal vein; SMA: Superior mesenteric artery; SMV: Superior mesenteric vein.
