Staging of hepatocellular carcinoma
According to the TNM staging system, there are four stages of hepatocellular carcinoma based on the tumor size, lymph node involvement, and distant metastasis.[1]
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 |
