Overview
Bladder cancer may be classified into several subtypes based on TNM system.
TNM Staging
- Stage 0a[1]
TNM | Definition |
---|---|
Ta | Non-invasive papillary urothelial carcinoma |
N0 | No regional lymph node metastasis |
M0 | No distant metastasis |
- Stage 0is
TNM | Definition |
---|---|
Tis | Non-invasive flat urothelial carcinoma |
N0 | No regional lymph node metastasis |
M0 | No distant metastasis |
- Stage I
TNM | Definition |
---|---|
T1 | The tumor is invasive. It has grown into the lamina propria but has not grown into the muscle of the bladder wall |
N0 | No regional lymph node metastasis |
M0 | No distant metastasis |
- Stage II
TNM | Definition |
---|---|
T2a | The tumor has grown into the inner half of the muscle of the bladder wall |
N0 | No regional lymph node metastasis |
M0 | No distant metastasis |
TNM | Definition |
---|---|
T2b | The tumor has grown into the outer half of the muscle of the bladder wall |
N0 | No regional lymph node metastasis |
M0 | No distant metastasis |
- Stage III
TNM | Definition |
---|---|
T3a | The tumor has grown into the fatty tissue around the bladder but can only be seen through a microscope |
N0 | No regional lymph node metastasis |
M0 | No distant metastasis |
TNM | Definition |
---|---|
T3b | The tumor has grown into the fatty tissue around the bladder and can be seen on imaging tests or be felt by the surgeon |
N0 | No regional lymph node metastasis |
M0 | No distant metastasis |
TNM | Definition |
---|---|
T4a | The tumor has grown into the prostate, seminal vesicles, uterus or vagina |
N0 | No regional lymph node metastasis |
M0 | No distant metastasis |
- Stage IV
TNM | Definition |
---|---|
T4b | The tumor has grown into the pelvic wall or the abdominal wall |
N0 | No regional lymph node metastasis |
M0 | No distant metastasis |
TNM | Definition |
---|---|
Any T | The tumor may be T1, T2, T3 or T4 |
N1, N2 or N3 | The cancer has spread to regional lymph nodes |
M0 | No distant metastasis |
TNM | Definition |
---|---|
Any T | The tumor may be T1, T2, T3 or T4 |
Any N | The cancer may have spread to one or more regional lymph nodes |
M1 | Distant metastasis |
