- Resectable adenocarcinoma (according to the NCCN classification 2014): absence of distant organ or distal lymph node metastases, absence of evidence of superior mesenteric vein (SMV) and portal vein distortion, tumour thrombus, or venous encasement, the existence of clear fat planes around the celiac axis, hepatic artery and superior mesenteric artery (SMA). Resectability is evaluated on arterial-phase and portal-phase IV contrast-enhanced multislice CT-scan of the pancreas (slice thickness: 2.5 mm), as evaluated in a multidisciplinary staff meeting including at least one radiologist and one expert surgeon.
