Question:
EOD 2018/Regional Nodes--Liver: Are the celiac axis lymph nodes considered regional lymph nodes or distant lymph nodes for a 2025 liver primary?
Discussion:
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:
- Caval
- Hepatic, NOS
- Hepatic artery
- Hepatic pedicle
- Inferior vena cava
- Porta hepatis (portal) (hilar) [in hilus of liver]
- Periportal
- Portal vein
- Regional lymph node(s), NOS
Based on this information, should celiac axis lymph nodes be considered as regional for liver primaries when coding EOD Regional Nodes?
Answer:
Code celiac axis lymph nodes as regional in EOD Regional Nodes for liver primaries.
