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:** Para-aortic nodes are now regional instead of distant.
**Note 3:** 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 4:** Isolated tumor cells (ITCs) are defined as single tumor cells or small clusters not greater than 0.2 mm, usually detected by immunohistochemical (IHC) or molecular methods. ITCs do not usually show evidence of malignant activity (e.g., proliferation or stromal reaction). Lymph nodes with ITCs only are not counted as positive nodes
* For positive ITCs with NO regional lymph node involvement, code 050.
