Notes

**Note 1**: Inferior phrenic nodes are classified as regional nodes for AJCC 7 staging and coded in CS Lymph Nodes. **Note 2**: Periduodenal and peripancreatic nodes are distant for tumors in the left liver, and gastrohepatic nodes are distant for tumors in the right liver. If both lobes of liver are involved, code involvement of periduodenal/peripancreatic and gastrohepatic nodes in CS Lymph Nodes. **Note 3**: Caval nodes are classified as distant for AJCC 7 staging.
