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:** **Bilateral or Contralateral nodes** * Bilateral or contralateral nodes are classified as regional nodes for truncal tumors (C445) with bidirectional drainage to primary nodal basins, as shown on lymphoscintigraphy. * Truncal tumors may also drain to both cephalad and caudal primary nodal basins as shown on lymphoscintigraphy. * Clinical assessment of bilateral/contralateral or cephalad/caudal regional nodal involvement is required for tumors where lymphoscintigraphy is not performed **Note 3:** **Nodal basins** * Contiguous or secondary nodal basins are the next nodal drainage basins beyond the primary nodal basins and are coded as regional nodes. **Note 4:** **Lymph nodes, NOS** * Code 800 if regional lymph nodes are involved, but there is no indication which ones are involved.Default
