TNM clinical classification
T - primary tumour
|
T value |
Description |
|---|---|
|
TX |
Primary tumour cannot be assessed |
|
T0 |
No evidence of primary tumour |
|
Tis |
Carcinoma in situ/highâgrade dysplasia |
|
T1 |
Tumour invades lamina propria, muscularis mucosae, or submucosa |
|
T1a - Tumour invades lamina propria or muscularis mucosae |
|
|
|
T1b - Tumour invades submucosa |
|
T2 |
Tumour invades muscularis propria |
|
T3 |
Tumour invades adventitia |
|
T4 |
Tumour invades adjacent structures |
|
|
T4a - Tumour invades pleura, pericardium, azygos vein, diaphragm, or peritoneum |
|
|
T4b - Tumour invades other adjacent structures such as aorta, vertebral body, or trachea |
N - regional lymph nodes
| N value | Description |
|---|---|
|
NX |
Regional lymph nodes cannot be assessed |
|
N0 |
No regional lymph node metastasis |
|
N1 |
Metastasis in 1 to 2 regional lymph nodes |
|
N2 |
Metastasis in 3 to 6 regional lymph nodes |
|
N3 |
Metastasis in 7 or more regional lymph nodes |
M - distant metastasis
| M value | Description |
|---|---|
|
M0 |
No distant metastasis |
|
M1 |
Distant Metastasis |
TNM pathological classification
pT - primary tumour
The pT and pN categories correspond to the T and N categories as per above.
|
pN value |
Description |
|---|---|
|
pN0 |
Histological examination of a regional lymphadenectomy specimen will ordinarily include 7 or more lymph nodes. If the lymph nodes are negative, but the number ordinarily examined is not met, classify as pN0 |
