Overview
According to the American Joint Committee on Cancer (AJCC) staging system, there are 4 stages of malignant liver mass, based on 3 factors: tumor size, lymph node invasion, and metastasis. Each stage is assigned a letter and a number that designate T for tumor size, N for node invasion, and M for metastasis.
Staging
- The table below summarizes the staging system for malignant liver mass, based on 3 factors: tumor size, lymph node invasion, and metastasis.
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) |
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 |
