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:** **Nodal metastasis rare** * Nodal metastasis is very rare in gastrointestinal stromal tumors (GISTs) and surgeons generally agree that nodal dissection is not indicated. In the absence of information on regional lymph node status for a localized tumor, code as none (000). **Note 3:** **EOD references** * See the chapter (schema) corresponding to the primary site for information about regional nodes. * *For example*: For primary colon GIST, see the colon chapter (schema) for regional nodes information. * **Esophagus**: C150-C155, C158-C159 * **Small Intestine**: C170-C172, C178-C17 * **Stomach**: C160-C166, C168-C169 * **Appendix**: C181 * **Colon and Rectum**: C180, C182-C189, C199, C209 * **Retroperitoneum**: C480-C482, C488 **Note 4:** **Lymph nodes, NOS** * Code 800 if regional lymph nodes are involved, but there is no indication which ones are involved.Default
