CS Mets at DX

Note 1: Lymph nodes from the supraclavicular region down to the celiac region previously considered to be distant are now regional.
Note 2: Lymph node stations/groups are listed in parentheses when applicable. See page 107 of the AJCC TNM 7th Ed. for an illustration.

Code	Description	TNM 7 Map	TNM 6 Map	SS77 Map	SS2000 Map
00	No; none	M0	M0	NONE	NONE
10	Distant lymph node(s), NOS	M1	M1NOS	D	D
11	OBSOLETE DATA RETAINED V0200 Considered regional in AJCC 7th Edition See CS Lymph Nodes code 250 Upper thoracic esophagus only: Cervical lymph nodes M1 Lower thoracic (abdominal) esophagus only: Celiac lymph nodes (20) M1	ERROR	M1a	D	D
12	OBSOLETE DATA REVIEWED AND CHANGED V0200 The specified lymph nodes in code 12 were considered distant in AJCC 6th Edition and are considered regional in AJCC 7th Edition EXCEPT for common hepatic and splenic lymph nodes which are still considered distant and are included in code 15.
