Note 1 Physician statement of Extranodal Extension (ENE) Pathological or physician pathological staging can be used to code this data item when there is no other information available.
Note 2 Extranodal extension is defined as "the extension of a nodal metastasis through the lymph node capsule into adjacent tissue." ENE is the preferred terminology. Other names include extranodal spread, extracapsular extension, or extracapsular spread."
- "A regional node extending into a distant structure or organ is categorized as ENE and is not recorded as distant metastatic disease."
Note 3 Be aware that the rules for coding ENE for head and neck sites compared to non-head and neck sites are different.
Note 4 Code the status of extranodal extension assessed on the surgical resection specimen for the most involved regional lymph node(s). Do not code ENE for any distant nodes.
- If codes 0, 1, or 7 are used, this indicates that the lymph nodes were surgically resected and Scope of Regional Lymph Node Surgery (NAACCR Data Item 1292) must be 3-7
