CS Lymph Nodes
This input is used for staging
Notes
**Note 1**: Code only regional nodes and nodes, NOS in this field. Distant nodes are coded in CS Mets at DX. **Note 2**: Pericholedochal (nodes of the common bile duct), superior mesenteric, and pyloric nodes are classified as distant for AJCC 7 staging. They are coded in CS Mets at DX. **Note 3**: The specific location of the mesenteric nodes determines whether they are regional or distant. If the specific location is not described, code 800, Lymph Nodes, NOS. **Note 4**: Porta hepatic nodes are considered distant for Body and Tail and should be coded in CS Mets at DX, code 10. If the specific location for hepatic nodes is not described, code 110, Regional Lymph nodes - Hepatic in CS Lymph Nodes.Default
