EOD Regional Nodes

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:** **Gastrohepatic ligament or gastrohepatic level nodes** * Imaging studies often refer to involved nodes in the gastrohepatic ligament or at the gastrohepatic level for esophageal primaries. Code as left gastric nodes if there is no more specific information. **Note 3:** **CLINICAL AND PATHOLOGICAL codes** * This schema has lymph node codes that are defined as **CLINICAL** assessment only or **PATHOLOGICAL** assessment only. **No surgical resection** * Use **CLINICAL** assessment only codes (725, 750, 775) when there is a clinical work up only and there is **NO surgical resection of the primary tumor or site** WITH * Any microscopic examination of regional lymph nodes, which includes FNA, core biopsy, sentinel node biopsy, lymph node excision, or lymph node dissection done during the clinical work up. **Surgical resection without neoadjuvant therapy** * Use **PATHOLOGICAL** assessment only codes (300, 700) when there is a **surgical resection of the primary tumor or site** WITH * Any microscopic examination of regional lymph nodes, which includes FNA, core biopsy, sentinel node biopsy, lymph node excision done or lymph node dissection performed. **Surgical resection after neoadjuvant therapy** * If patient has neoadjuvant therapy, and the clinical assessment is equal to or greater than the pathological assessment, then the clinical assessment codes take priority. Otherwise, code the pathologic assessment. * See ***EOD 2018 General Instructions*** for further instructions on coding cases with neoadjuvant therapy, https://seer.cancer.gov/tools/staging/eod/.
