Transitional cell carcinoma of the ureter staging uses the TNM system and is very similar to staging of TCC of the bladder and to staging of TCC of the renal pelvis.
TNM staging (8th edition)
T
-
Ta: noninvasive papillary tumor
-
Tis: in situ (noninvasive flat)
-
T1: through lamina propria into sub-epithelial connective tissues
-
T2: into muscularis propria
-
T3: invasion into periureteric fat
-
T4: direct invasion into adjacent organs/structures
N
-
N0: no nodal involvement
-
N1: single node involved <2 cm
-
N2
- single node >2 cm, or
- multiple nodes
M
-
M0: no metastases
-
M1: metastases identified
Staging groups
Individual TNM stages can then be grouped:
-
stage 0: Ta or Tis, N0, M0
-
stage I: T1, N0, M0
-
stage II: T2(a or b), N0, M0
-
stage III: T3(a or b) or T4a, N0, M0
-
stage IV
- T4b, any N, any M
- N1-3, any T, any M
