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 EOD Mets. **Note 2:** The specific location of the mesenteric nodes determines whether they are regional or distant. If the specific location is not described, code in EOD Regional Nodes. **Note 3:** Porta hepatic nodes are considered distant for Body and Tail and should be coded in EOD Mets. If the specific location for hepatic nodes is not described, code in EOD Regional Nodes.
