Overview
Hepatocellular carcinoma may be classified according to the histological subtypes. The staging of HCC is based on the TNM staging system.
Classification
- Hepatocellular carcinoma may be classified according to the histological subtypes:[1][2]
- Fibrolamellar carcinoma
- Sarcomatoid HCC
- Undifferentiated carcinoma
- Combined HCC-
cholangiocarcinoma (HCC-CC) - Lymphoepithelioma
- Scirrhous hepatocellular carcinoma (scirrhous HCC)

Abbreviations: Combined HCC-cholangiocarcinoma (HCC-CC)*
Staging
According to the TNM staging system, there are four stages of hepatocellular carcinoma based on the tumor size, lymph node involvement, and distant metastasis.[3]
Primary tumor
| TX | Primary tumour cannot be assessed |
| T0 | No evidence of primary tumour |
| T1 | A single tumour with no invasion into the blood vessels of the liver |
| T2 | A single tumour with invasion into the blood vessels or multiple tumours, none more than 5 cm in size |
| T3a | Multiple tumours, with any tumour larger than 5 cm |
| T3b | The tumour has grown into either the portal or hepatic vein |
| T4 | The tumour has grown into nearby organs (other than the gallbladder) or the tumour has grown into the layer of tissue that covers the organs in the abdomen (visceral peritoneum) |
Regional lymph node
| NX | Regional lymph nodes cannot be assessed |
| NX | No regional lymph node metastasis |
| NX | Regional lymph node metastasis |
Distance metastasis
| M0 | No distant metastasis |
| M1 | Distant metastasis |
