CS Lymph Nodes
Notes
**Note 1**: Code only regional nodes and nodes, NOS, in this field. Distant nodes are coded in CS Mets at DX. **Note 2**: Inferior phrenic nodes are classified as regional nodes for AJCC 7 staging. They are now coded in CS Lymph Nodes. **Note 3**: Periduodenal and peripancreatic nodes are regional for tumors in the right liver, and gastrohepatic nodes are regional for tumors in the left liver, for AJCC 7 staging. Use codes 120 and 130 only for regional nodes specific to the involved lobe of liver. Use code 140 if both lobes of liver are involved and periduodenal/peripancreatic and gastrohepatic nodes are involved. **Note 4**: Caval nodes are classified as distant nodes and coded in CS Mets at DX.Code | Description | AJCC 7 N | TNM 6 N | Summary Stage 1977 N | Summary Stage 2000 N |
