Collaborative Stage

Collaborative Stage for TNM 7 - Revised 11/20/2010 [ Schema ]

BileDuctsIntraHepat

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: Inferior phrenic nodes are classified as regional nodes for AJCC 7 staging. They are now coded in CS Lymph Nodes.
Note 3: Periduodenal and peripancreatic nodes are regional for tumors in the right liver, and gastrohepatic nodes are regional for tumors in the left liver, for AJCC 7 staging. Use codes 120 and 130 only for regional nodes specific to the involved lobe of liver. Use code 140 if both lobes of liver are involved and periduodenal/peripancreatic and gastrohepatic nodes are involved.
Note 4: Caval nodes are classified as distant nodes and coded in CS Mets at DX.

000	No regional lymph node involvement	N0	*	NONE	NONE
100	OBSOLETE DATA RETAINED AND REVIEWED V0203 Gastrohepatic nodes are regional for tumors in left liver in AJCC 7. Caval nodes are distant in AJCC 7.

* For CS Lymph Nodes codes 000-999, the N and M categories for AJCC 6 staging are assigned based on the coding of CS Lymph Nodes and CS Mets at DX as shown in the Lymph Nodes Mets at DX AJCC 6 Table for this schema.
