The article deals with kidney cancer staging. A general discussion of staging is found in cancer staging.

General

  • TNM staging used.

TNM staging system

Tumour stage

Renal sinus invasion

Renal sinus invasion is when any of the following are present:[1]

  1. Tumour in an endothelial lined space of the renal sinus.
  2. Tumour touching renal sinus fat.
  3. Tumour within the loose connective tissue of the renal sinus.

Notes:

  • Most cases are pT1a or pT3a.
    • pT2 is very rare and pT1b is uncommon for CCRCC.[2]

Lymph node stageing

Notes:

  • Previously divided into N1 (one lymph node positive) and N2 (multiple lymph nodes positive).
    • Now only N1 - was changed in 2009.[3]
      • There is data to suggest N1 and N2 behave differently;[4] however, it is disputed.[5][6]
