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: If information about named regional lymph nodes is available, use codes 100, 400, 450 or 500, rather than codes 600, 650, or 700.

^ For CS Lymph Nodes codes 100-400, 450, and 500 ONLY, when CS Lymph Nodes Eval is 0, 1, 5, or 9, the N category is assigned from the Lymph Nodes Clinical Evaluation AJCC 7 Table, using Regional Nodes Positive and CS Site-Specific Factor 1; when CS Lymph Nodes Eval is 2, 3, 6, 8, or not coded, the N category is determined from the Lymph Nodes Pathologic Evaluation AJCC 7 Table Also Used When CS Lymph Nodes Eval Is Not Coded, using Regional Nodes Positive.
* For CS Lymph Nodes codes 100-500 ONLY, when CS Lymph Nodes Eval is 0, 1, 5, or 9, the N category is assigned from the Lymph Nodes Clinical Evaluation AJCC 6 Table, using Regional Nodes Positive and CS Site-Specific Factor 1; when CS Lymph Nodes Eval is 2, 3, 6, 8, or not coded, the N category is determined from the Lymph Nodes Pathologic Evaluation AJCC 6 Table Also Used When CS Lymph Nodes Eval Is Not Coded, using Regional Nodes Positive.
