Collaborative Stage for TNM 7 - Revised 09/17/2010 [ Schema ]
CS Site-Specific Factor 3
Clinical Status of Lymph Node Mets
- 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 elective lymphadenectomy. "Macrometastases" are clinically detectable nodal metastases confirmed by therapeutic lymphadenectomy or needle biopsy.
- Note 2: Assign code 000 if either there is no lymph node involvement (CS Lymph Nodes is coded 000), or there are in-transit metastases but no regional lymph node involvement (CS Lymph Nodes is coded 400).
- Note 3: Assign code 000 if there are clinically apparent lymph node metastases but they are pathologically negative.
- Note 4: Assign code 010 if lymph nodes are negative on palpation and/or imaging but are positive, including positive for isolated tumor cells (ITCs), on pathology.
- Note 5: Assign code 010 if there is microscopic confirmation of lymph node metastases, including ITCs, but there is no documentation of the clinical status.
- Note 6: Assign code 020 if there are clinically apparent lymph node metastases, whether they are confirmed by pathology or pathology is not performed.
