Notes

**Note 1:** Code only regional nodes and nodes, NOS, in this field. Distant nodes are coded in M (distant metastasis). **Note 2:** Hepatoduodenal nodes are regional for primaries of the lesser curvature of the stomach. They are coded in M (distant metastasis) for all other subsites in this schema. **Regional lymph nodes** Celiac Hepatic (excluding gastrohepatic) Hepatoduodenal Left gastric (superior gastric), NOS: Cardial Cardioesophageal Gastric, left Gastropancreatic, left Lesser curvature Lesser omental Paracardial Hepatoduodenal (for lesser curvature) Nodule(s) in perigastric fat Pancreaticosplenic (pancreaticolienal) Pancreaticoduodenal Perigastric, NOS Peripancreatic Right gastric (inferior gastric), NOS Gastrocolic Gastroduodenal Gastroepiploic (gastro-omental), right or NOS Gastrohepatic Greater curvature Greater omental Pyloric, NOS: infrapyloric, subpyloric, suprapyloric Splenic (lienal), NOS: Gastroepiploic (gastro-omental), left Splenic hilar
