Localized and resectable
No distant metastases
No radiographic evidence of SMV or portal vein distortion
Clear fat planes around the celiac axis, hepatic artery, and SMA
Borderline resectable
No distant metastases
Venous involvement of the SMV or portal vein with distortion or narrowing of the vein or occlusion of the vein with suitable vessel proximal and distal, allowing for safe resection and replacement
Gastroduodenal artery encasement up to the hepatic artery with short segment encasement or direct abutment of the hepatic artery, without extension to the celiac axis
Tumor abutment of the SMA not to exceed greater than 180 degrees of the circumference of the vessel wall
Unresectable
Head
	Distant metastases
	Greater than 180 degrees SMA encasement, any celiac abutment
	Unreconstructable SMV/portal occlusion
	Aortic or inferior vena cava invasion or encasement
Body
	Distant metastases
	SMA or celiac encasement greater than 180 degrees
	Unreconstructable SMV/portal occlusion
	Aortic invasion
Tail
	Distant metastases
	SMA or celiac encasement greater than 180 degrees
Nodal status
	Metastases to lymph nodes beyond the field of resection should be considered unresectable
