## CS Lymph Nodes

### Notes

**Note 1**: Regional nodes in codes 100-300 include contralateral and bilateral nodes. **Note 2**: Involvement of inguinal, pelvic, or external iliac lymph nodes (codes 300 and 400) WITHOUT previous scrotal or inguinal surgery prior to presentation of the testis tumor is coded in CS Mets at DX, as distant lymph node involvement.Code | Description | AJCC 7 N | TNM 6 N | Summary Stage 1977 N | Summary Stage 2000 N |
