| Primary Site | Histology | Staging Type |
|---|---|---|
| C220 | 8000-8157, 8162-8169, 8190-9136, 9141-9582, 9700-9701 | Summary Stage only |

If you are working with a site/histology that only summary stages and you need to directly code it, please use the SEER Summary Stage 2000 manual
Notes
C220 Liver
C221 Intrahepatic bile duct
Note 1: This schema is based on the UICC chapter Liver-Hepatocellular Carcinoma pages 110-113.
- Primary site C221 with histologies 8170-8175 is not listed in this chapter of the UICC manual; however, it is included in this schema, but is not TNM staged
Note 2: For primary site C220 and cholangiocarcinoma histologies (M-8160, 8161, and 8180), see the Bile DuctsIntraHepat schema.
Note 3: Although the presence of cirrhosis is an important prognostic factor, it does not affect the TNM classification, being an independent prognostic variable.
Note 4: In addition to directly assigning TNM, Summary Stage 2000 (SS2000) must be captured. If directly assigning SS2000, use the Liver and Intrahepatic Bile Ducts chapter on page 108 of the SS2000 on-line manual.
