EOD Regional Nodes
This input is used for staging
Notes
**Note 1:** Code only regional nodes and nodes, NOS, in this field. Distant nodes are coded in the field EOD Mets. **Note 2:** Inguinal lymph nodes are no longer coded as regional lymph nodes. See EOD Mets. **Note 3:** 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 **Note 4:** Regional lymph nodes include (bilateral and contralateral) - Intrabdominal - Para-aortic, NOS + Aortic + Lateral aortic/lateral lumbar + Periaortic - Pelvic, NOS + Iliac, NOS + Common + External + Internal (hypogastric) (obturator) + Paracervical + Parametrial + Sacral, NOS + Lateral (laterosacral) + Middle (promontorial) (Gerota's node) + Presacral + Uterosacral - Retroperitoneal, NOS **Note 5:** Code 800 if regional lymph nodes are involved, but there is no indication which ones are involved.Default
