EOD Regional Nodes
This input is used for staging
Notes
**Note 1:** **Regional nodes and nodes, NOS** * Code only regional nodes and nodes, NOS, in this field. Distant nodes are coded in EOD Mets. **Note 2:** **Inguinal lymph nodes** * Inguinal lymph nodes are no longer coded as regional lymph nodes. See EOD Mets. **Note 3:** **Isolated tumor cells** * 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:** **Lymph nodes, NOS** * Code 800 if regional lymph nodes are involved, but there is no indication which ones are involved.Default
