CS Lymph Nodes

Note 1: Code only regional nodes and nodes, NOS, in this field. Distant nodes are coded in CS Mets at DX.
Note 2: Celiac and superior mesenteric nodes are classified as regional nodes for AJCC staging and are coded in CS Lymph Nodes.
Note 3: Para-aortic and pericaval lymph nodes are classified as regional nodes for AJCC 7 staging and are now coded in CS Lymph Nodes.
