Anatomic regions, vascular landmarks and tumor invasion groups

Margins of the anatomic regions (dashed lines). Index arteries: left lateral anatomic region: at the left side of the coeliac trunk and the left renal artery; interaortocaval anatomic region: at the common hepatic artery and the right side of the coeliac trunk; right lateral anatomic region: at the right renal artery and the superior mesenteric artery. Tumor invasion groups: tumor isolated in right lateral anatomic region (1R), tumor isolated in left lateral anatomic region (1L), tumor invading right lateral + interaortocaval anatomic region (2R), invading left lateral + interaortocaval anatomic region (2L), tumor invading right lateral + interaortocaval + left lateral anatomic region or isolated in the interaortocaval anatomic region (3)
