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**: Periaortic and pericaval lymph nodes are classified as regional nodes for AJCC 7 staging. They are now coded in CS Lymph Nodes.| Code | Description | AJCC 7 N | TNM 6 N | Summary Stage 1977 N | Summary Stage 2000 N |
