Collaborative Stage

Collaborative Stage for TNM 7 - Revised 12/27/2009 [ Schema ]

CS Site-Specific Factor 2
Size of Metastasis in Lymph Nodes

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

Code	Description
000	No regional lymph node(s) involved
001-979	1 - 979 mm (exact size of lymph node metastasis in millimeters)
980	980 mm or larger
988	Not applicable: Information not collected for this case (May include cases converted from code 888 used in CSv1 for "Not applicable" or when the item was not collected. If this item is required to derive T, N, M, or any stage, use of code 988 may result in an error.))
