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:** **CLINICAL AND PATHOLOGICAL** * This schema has lymph node codes that are defined as **CLINICAL** assessment only or **PATHOLOGICAL** assessment only. + **CLINICAL** assessment only codes (100, 200, 300) are used when there is a clinical work up only and there is no surgical resection of the primary tumor or site. This includes FNA, core biopsy, sentinel node biopsy, or lymph node excision - *Exception:* If patient has neoadjuvant therapy, and the clinical assessment is greater than the pathological assessment, then the clinical assessment code would take priority + **PATHOLOGICAL** assessment only codes (400, 500) are used when - Primary tumor or site surgically resected with - Any microscopic examination of regional lymph nodes. Includes - FNA, core biopsy, sentinel node biopsy or lymph node excision done during the clinical work up and/or - Lymph node dissection performed * Remaining codes (no designation of **CLINICAL** or **PATHOLOGICAL** only assessment) can be used based on clinical and/or pathological information * **Code 000** is used when there is no evidence of regional lymph nodes clinically **OR** lymph nodes are negative pathologically (*Regional Nodes Positive = 00, 98*) * **Code 800** is used when there are positive nodes (clinical or pathological), but the specific lymph nodes or number of positive nodes is unknown (*Regional Nodes Positive = 97*) * **Code 999** is used when the lymph node status is unknown and *Regional Nodes Positive = 99* **Note 3:** **Regional lymph nodes include** - Iliac, NOS + External + Internal (hypogastric, obturator) - Inguinal, NOS + Node of Cloquet or Rosenmuller (highest deep inguinal) + Superficial [femoral] - Pelvic, NOS **Note 4:** **Lymph nodes, NOS** * Code 800 if regional lymph nodes are involved, but there is no indication which ones are involved.Default
