Resectable |
Tumor-artery relationship: No radiographic evidence of arterial abutment (celiac, SMA, or hepatic artery) |
Tumor-vein relationship: Tumor-induced narrowing, if present, is <50% of the circumference of the SMV, PV, or SMV-PV confluence |
Borderline Resectable |
Artery: Tumor abutment (<180˚ of the circumference) of SMA or celiac artery. Tumor abutment or short segment encasement (>180˚) of the hepatic artery |
Vein: Tumor induced narrowing of >50% of SMV, PV, or SMV-PV or short segment occlusion of SMV, PV, SMV-PV with suitable PV (above) and SMV (below) to allow for safe vascular reconstruction |
Extrapancreatic findings: CT scan findings suspicious, but not diagnostic of, metastatic disease (for example, small indeterminate liver lesions which are too small to characterize) |
Locally Advanced |
Artery: Tumor encasement (>180˚ of the circumference) of SMA or celiac artery |
Vein: Occlusion of SMV, PV, or SMV-PV without suitable vessels above and below the tumor to allow for reconstruction (no distal or proximal target for vascular reconstruction) |
Extrapancreatic findings: No evidence of peritoneal, hepatic, extra-abdominal metastases |
Metastatic |
Evidence of peritoneal or distant metastases |
