EOD 2018/Regional Nodes--Liver: Are the celiac axis lymph nodes considered regional lymph nodes or distant lymph nodes for a 2025 liver primary?
According to the AJCC CAnswer Forum (https://cancerbulletin.facs.org/forums/node/160948), celiac axis nodes are considered regional for the liver. However, for liver primaries, Extent of Disease (EOD) regional lymph nodes list the following as regional lymph nodes:
