Collaborative Stage

Collaborative Stage for TNM 7 - Revised 12/01/2009 [ Schema ]

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 the clinician says "adnexa palpated" but doesn't mention lymph nodes, assume lymph nodes are not involved, code "000".
Note 3: If either exploratory/definitive surgery is done with no mention of lymph nodes, assume nodes are negative.
Note 4: Regional nodes includes bilateral and contralateral involvement of named nodes.
