TNM clinical classification
T - primary tumour
| T value | Description |
|---|---|
|
TX |
Primary tumour cannot be assessed |
|
T0 |
No evidence of primary tumour |
|
Ta |
Non‐invasive papillary carcinoma |
|
Tis |
Carcinoma in situ: ‘flat tumour’ |
|
T1 |
Tumour invades subepithelial connective tissue |
|
T2 |
Tumour invades muscularis propria |
|
T2a |
Tumour invades superficial muscularis propria (inner half) |
|
T2b |
Tumour invades deep muscularis propria (outer half) |
|
T3 |
Tumour invades perivesical tissue: T3a – microscopically T3b - macroscopically (extravesical mass) |
|
T4 |
Tumour invades any of the following: prostate stroma, seminal vesicles, uterus, vagina, pelvic wall, abdominal wall |
|
T4a |
Tumour invades prostate stroma, seminal vesicles, uterus or vagina |
|
T4b |
Tumour invades pelvic wall or abdominal wall |
N - regional lymph nodes
| N value | Description |
|---|---|
|
NX |
Regional lymph nodes cannot be assessed |
|
N0 |
No regional lymph node metastasis |
|
N1 |
Metastasis in a single lymph node in the true pelvis (hypogastric, obturator, external iliac, or presacral) |
|
N2 |
Metastasis in multiple regional lymph nodes in the true pelvis (hypogastric, obturator, external iliac, or presacral) |
|
N3 |
Metastasis in a common iliac lymph node(s) |
M - distant metastasis
| M value | Description |
|---|---|
|
M0 |
No distant metastasis |
|
M1a |
Non‐regional lymph nodes |
|
M1b |
Other distant metastasis |
TNM pathological classification
pT - primary tumour
The pT and pN categories correspond to the T and N categories.
