Clinical Status of Lymph Node Mets

Notes

**Note 1**: AJCC defines microscopic lymph node metastases or "micrometastases" as those which are clinically inapparent by palpation and/or imaging but are pathologically positive. Micrometastases are diagnosed after sentinel or other node biopsy or elective lymphadenectomy. "Macrometastases" are clinically detectable nodal metastases confirmed by therapeutic lymphadenectomy or when nodal metastasis exhibits gross extracapsular extension. **Note 2**: Use code 005 if nodes are described as clinically negative and are also negative on pathologic examination, or no pathologic examination is performed. Use code 010 if nodes are described as clinically negative but are positive on pathologic examination. **Note 3**: Use codes 043-050 if nodes are described as clinically positive. **Note 4**: Use code 100 to code information about clinically apparent in transit metastasis with or without occult nodal metastases. Information about clinically inapparent in transit metastasis ("occult" metastasis found only on pathologic examination) is not collected in this site-specific factor. **Note 5**: Use code 150 to code information about nodal involvement with in transit satellite metastases that are both clinically apparent. **Note 6**: Use code 999 if no information is available about the clinical evaluation of lymph nodes or in transit metastasis. **Note 7**: Codes 043-050 and 150 are appropriate for cases with neoadjuvant treatment, where nodes are described as clinically positive before treatment but are shown to be either negative or positive on pathologic examination after treatment.
