Collaborative Stage

Collaborative Stage for TNM 7 - Revised 11/29/2009 [ Schema ]

CS Lymph Nodes

Note 1: Code only regional nodes and nodes, NOS, in this field. Distant nodes are coded in the field Mets at DX.
Note 2: Celiac and superior mesenteric nodes are listed in this field rather than Mets at DX, because AJCC classifies them as N2 and not M1.
Note 3: Para-aortic lymph nodes were reclassified from distant to regional nodes in AJCC 7th Ed.
Note 4: In some cases, determination of the M category for TNM 6 is based on this field as well as CS Mets at DX.

600	Superior mesenteric lymph node(s)	N2	N1	D	RN
610	(500) OR (600) + 110	N2	N1	D	RN
620	Regional lymph nodes: Para-aortic Pericaval	N2	*	D	D
630	620 + any of 100, 110, 200, 210, 500 or 600 Any regional lymph node(s) as listed in codes 100, 110, 200, 210, 500 or 600 + para-aortic and/or pericaval lymph node(s)	N2	*	D	D
650	Stated as N2, NOS	N2	N1	D	RN
800	Lymph nodes, NOS	N1	N1	RN	RN
999	Unknown; not stated Regional lymph node(s) cannot be assessed Not documented in patient record	NX	NX	U	U

* When CS Lymph Nodes is coded 620 or 630, the 6th Edition N and M categories are determined by the code in CS Mets at DX using the Lymph Nodes Mets at DX Table.
