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:** "Vocal cord paralysis," "superior vena cava syndrome," and "compression of the trachea or the esophagus" are classified as either direct extension from the primary tumor or mediastinal lymph node involvement
* If these manifestations are caused by direct extension of the primary tumor, code as primary tumor involvement (EOD Primary Tumor, code 650)
* If the primary tumor is peripheral and clearly unrelated to vocal cord paralysis, SVC obstruction, or compression of the trachea, or the esophagus, these manifestations are secondary to lymph node involvement; code as mediastinal lymph node involvement (EOD Lymph Nodes, code 400)
* If unable to determine if these manifestations are due to direct extension or mediastinal lymph node involvement, record as mediastinal lymph node involvement (EOD Lymph Nodes, code 400)
**Note 3:** Code 800 if regional lymph nodes are involved, but there is no indication which ones are involved.
