Staging of transitional cell carcinoma of the renal pelvis

Transitional cell carcinoma of the renal pelvis is staged using the TNM system and is very similar to staging of TCC of the bladder and to staging of TCC of the ureter.

TNM staging

T
  • Ta: non invasive papillary tumour
  • Tis: in situ (non invasive flat)
  • T1: through lamina propria into sub-epithelial connective tissues
  • T2: into muscularis propria
  • T3: invasion into peripelvic fat or renal parenchyma
  • T4: direct invasion into adjacent structures or beyond renal capsule
N

Nodal staging is the same for TCC of any part of the urinary tract. 

  • N0: no nodal involvement
  • N1: single node involved <2cm
  • N2
    • single node 2-5cm or
    • multiple nodes all <5cm
  • N3: one or more nodes >5cm
M
  • M0: no metastases
  • M1: metastases identified

Staging groups

Individual TNM stages can then be grouped 3-4:

  • 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
