CS Lymph Nodes

This input is used in derivation

Notes

**Note 1**: Code only regional nodes and nodes, NOS, in this field. Distant nodes are coded in CS Mets at DX. **Note 2**: Celiac and superior mesenteric nodes are classified as regional nodes for AJCC staging and are coded in CS Lymph Nodes. **Note 3**: Para-aortic and pericaval lymph nodes are classified as regional nodes for AJCC 7 staging and are now coded in CS Lymph Nodes.
