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)

Staging
TNM staging system
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 |
