Collaborative Stage

Collaborative Stage for TNM 7 - Revised 08/19/2011 [ 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 other node biopsy or elective lymphadenectomy. "Macrometastases" are clinically detectable nodal metastases confirmed by needle biopsy or therapeutic lymphadenectomy.
Note 2: Use codes 005 or 010 if nodes are described as clinically negative. Use code 020 if nodes are described as clinically positive.
Note 3: Use code 999 if no information is available about clinical nodal involvement.
