Collaborative Stage for TNM 7 - Revised 10/27/2010 [ Schema ]

Pleura

CS Mets at DX

Note: Peridiaphragmatic nodes are considered regional nodes in AJCC 7 staging and are coded in CS Lymph Nodes.

Code	Description	TNM 7 Map	TNM 6 Map	SS77 Map	SS2000 Map
00	No distant metastasis	M0	*	NONE	NONE
10	Distant lymph node(s), including cervical nodes	M1	M1	D	D
35	Direct extension to contralateral lung	M1	M1	D	D
40	Distant metastases, except code 10 or 35 Discontinuous involvement of contralateral pleura/chest wall Carcinomatosis	M1	M1	D	D
50	(35 and/or 40) + 10 Distant metastasis plus distant lymph node(s)	M1	M1	D	D
60	Distant metastases, NOS Stated as M1 with no other information on distant metastasis	M1	M1	D	D
99	Unknown; distant metastasis not stated Distant metastasis cannot be assessed Not documented in patient record	M0	*	U	U

* For CS Mets at DX codes 00 and 99, the assignment of the M category for AJCC 6 staging is based on the value of CS Lymph Nodes as shown in the Lymph Nodes Mets at DX AJCC 6 Table for this schema.
