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. Regional nodes include bilateral and contralateral involvement of named nodes. **Note 2**: When both FIGO stage and regional lymph node detail are available, record the code with regional lymph node detail in preference to a statement of FIGO stage. **Note 3**: If either exploratory or definitive surgery is done with no mention of lymph nodes, assume nodes are negative. **Note 4**: If the clinician says "adnexa palpated" but does not mention lymph nodes, assume lymph nodes are not involved.| Code | Description | AJCC 7 N | TNM 6 N | Summary Stage 1977 N | Summary Stage 2000 N |
