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:** Regional lymph node involvement is rare. For this schema, if there is no mention of lymph node involvement clinically, assume that lymph nodes are negative. Code unknown (999) only when there is no available information on the extent of the patient's disease, for example when a lab-only case is abstracted from a biopsy report and no clinical history is available. **Note 3:** Code 800 if regional lymph nodes are involved, but there is no indication which ones are involved.
