TNM clinical classification

T - primary tumour

 T value

Description

cTX

Primary tumour cannot be assessed

cT0

No evidence of primary tumour

cTis

Carcinoma in situ*

cT1

Tumour 2 cm or less in greatest dimension

cT1a - Tumour 0.5 cm or less in greatest dimension

cT1b - Tumour greater than 0.5 cm and no more than 1 cm in greatest dimension

cT1c - Tumour greater than 1 cm but no more than 2 cm in greatest dimension

cT2

Tumour more than 2 cm but no more than 4 cm in greatest dimension

cT3

Tumour more than 4 cm in greatest dimension

cT4

Tumour involves coeliac axis, superior mesenteric artery and/or common hepatic artery

Note:

*Tis also includes the 'PanIN-III' classification

N - regional lymph nodes

N value

Description

cNX

Regional lymph nodes cannot be assessed

cN0

No regional lymph node metastasis

N1

Metastases in 1 to 3 regional lymph node

cN2

Metastases in 4 or more regional lymph node

M - distant metastasis

M value

Description

cM0

No distant metastasis

cM1

Distant Metastasis

TNM pathological classification

pT - primary tumour

The pT and pN categories correspond to the cT and cN categories as per above.

pN - regional lymph nodes

pN value

Description

pN0

Histological examination of a regional lymphadenectomy specimen will ordinarily include 12 or more lymph nodes. If the lymph nodes are negative, but the number ordinarily examined is not met, classify as pN0
