Collaborative Stage for TNM 7 - Revised 12/10/2009 [ Schema ]

Bladder

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: 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.
