EOD Regional Nodes
Notes
**Note 1:** Code only regional nodes and nodes, NOS, in this field. Distant nodes are coded in EOD Mets.
**Note 2:** When both the Federation Internationale de Gynecologie et d'Obstetrique (FIGO) stage and lymph node detail are available, record the code with lymph node detail in preference to a statement of FIGO stage.
**Note 3:** Regional lymph nodes include
- Aortic (lateral [lumbar], Periaortic, NOS)
- Iliac (common, external, internal [hypogastric], NOS)
- Lateral (laterosacral)
- Middle (promontorial) (Gerota’s node)
- Obturator
- Para-aortic
- Paracervical
- Parametrial
- Pelvic, NOS
- Presacral
- Sacral
- Uterosacral
