Overview
The staging of urethral cancer is based on the TNM staging system.
Staging
Definitions of TNM [1]
The American Joint Committee on Cancer has designated staging by TNM classification to define urethral cancer.
TNM | Definition | |
---|---|---|
TX | Primary tumor cannot be assessed. | |
T0 | No evidence of primary tumor. | |
Ta | Noninvasive papillary, polypoid, or verrucous carcinoma. | |
Tis | Carcinoma in situ. | |
T0 | No evidence of primary tumor. | |
T1 | Tumor invades subepithelial connective tissue. | |
T2 | Tumor invades any of the following: corpus spongiosum, prostate, periurethral muscle. | |
T3 | Tumor invades any of the following: corpus cavernosum, beyond prostatic capsule, anterior vagina, bladder neck. | |
T4 | Tumor invades other adjacent organs. | |
Urothelial (Transitional Cell) Carcinoma of the Prostate | ||
|
Carcinoma in situ, involvement of the prostatic urethra. | |
|
Carcinoma in situ, involvement of the prostatic ducts. | |
T1 | Tumor invades urethral subepithelial connective tissue. | |
T2 | Tumor invades any of the following: prostatic stroma, corpus spongiosum, periurethral muscle. | |
T3 | Tumor invades any of the following: corpus cavernosum, beyond prostatic capsule, bladder neck (extraprostatic extension). | |
T4 | Tumor invades other adjacent organs (invasion of the bladder).
other adjacent organs. | |
Regional Lymph Nodes | ||
NX | Regional lymph nodes cannot be assessed. | |
N0 | No regional lymph node metastasis. | |
N1 | Metastasis in a single lymph node 2 cm or less in greatest dimension. | |
N2 | Metastasis in a single node more than 2 cm in greatest dimension, or in multiple nodes. | |
Distant Metastasis | ||
M0 | No distant metastasis. | |
M1 | Distant metastasis. |
Anatomic Stage
