Collaborative Stage

Collaborative Stage for TNM 7 - Revised 12/06/2009 [ Schema ]

Esophagus

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: In 7th Edition, regional lymph nodes for any part of esophagus fall in the range from periesophageal/cervical to celiac region.
Note 3: Lymph nodes from the supraclavicular region down to the celiac region previously considered to be distant are now regional.
Note 4: Lymph node stations/groups are listed in parentheses when applicable. See page 107 of the AJCC TNM 7th Ed. for an illustration.

^ For codes 100-500 and 800, the N category is assigned based on the number of positive lymph nodes. ^ For codes 100-500 and 800 ONLY: when CS Regional Nodes Eval is 0, 1, 5, or 9, the N category is assigned from the Lymph Nodes Clinical Evaluation 7th Edition Table, using Reg LN Pos and CS Site-Specific Factor 1; when CS Regional Nodes Eval is 2, 3, 6, 8, or not coded, the N category is determined from the Lymph Nodes Pathologic Evaluation 7th Edition Table using Reg LN Pos.
* For codes 250 and 260 the N and M categories for AJCC 6th Edition are assigned based on the coding of this field and CS Mets at DX as shown in the Lymph Nodes Mets at DX Table AJCC 6
