Collaborative Stage

Collaborative Stage for TNM 7 - Revised 11/12/2010 [ Schema ]

CS Site-Specific Factor 7
Size of Metastasis in Lymph Nodes

Note: Code the size of the largest metastasis in a lymph node as documented in the pathology report, not the size of the lymph node. If the size of the metastasis is not documented in the pathology report, code the size of the largest involved lymph node as documented pathologically or clinically with pathology taking priority. Do not code the size of any node(s) coded in CS Mets at DX.
