CS Lymph Nodes

Note 1: Code only regional nodes and nodes, NOS, in this field. Distant nodes are coded in the field CS Mets at DX.
Note 2: Regional nodes include bilateral and contralateral involvement of named nodes.
Note 3: In some cases, determination of the N category for TNM 6 is based on this field and CS Mets at DX.

* For CS Lymph Nodes codes 150, 250, 350-450, and 505 ONLY, the N and M categories for AJCC 6 staging are assigned based on CS Lymph Nodes, CS Mets at DX, and CS Site-Specific Factor 2, Size of Metastasis in Lymph Nodes, as shown in the Lymph Nodes Size Mets 00 AJCC 6 Table, Lymph Nodes Size Mets 99 AJCC 6 Table, Lymph Nodes Size Mets 11, 40, 55, 60 AJCC 6 Table, and Lymph Nodes Size Mets 10 or 50 AJCC 6 Table.
