ECOG = European Cooperative Oncology Group, N = nodal, GVI = great vessel invasion.
*Radiological criteria for GVI is as follow: 1. irregular indentation at the tumor–vessel contact border, 2. slit-like narrowing of adjacent great vessels by the tumor, 3. presence of intra-luminal mass formation, 4. tumors contacting >5 cm of adjacent great vessel and obliteration of the intervening fat plane between tumor and adjacent great vessel, and 5. tumors contacting more than half of the circumference of the aortic wall.
