Overview
The staging of urethral cancer is based on the TNM system. Moreover, it may be classified into 5 subtypes based on the depth of invasion.
Staging
Stage Definitions by Depth of Invasion
- Stage 0 (Tis, Ta): Limited to mucosa
- Stage A (T1): Submucosal invasion
- Stage B (T2): Infiltrating periurethral muscle or corpus spongiosum
- Stage C (T3): Infiltration beyond periurethral tissue
- Female: Vagina, labia, muscle
- Male: Corpus cavernosum, muscle
- Stage D1 (N+): Regional nodes; pelvic and inguinal
- Stage D2 (N+, M+): Distant nodes; visceral metastases
Definitions of TNM [1]
The American Joint Committee on Cancer has designated staging by TNM classification to define urethral cancer.
