Pathologic TNM staging of renal cell carcinoma, AJCC 8th edition
Primary tumor (pT)
  • pTX: Primary tumor cannot be assessed
  • pT0: No evidence of primary tumor
  • pT1a: Tumor ≤ 4 cm, limited to the kidney
  • pT1b: Tumor > 4 cm and ≤ 7 cm, limited to the kidney
  • pT2a: Tumor > 7 cm and ≤ 10 cm, limited to the kidney
  • pT2b: Tumor > 10 cm, limited to the kidney
  • pT3a: Tumor invades renal vein / branches, perirenal fat, renal sinus fat or pelvicaliceal system
  • pT3b: Tumor extends into vena cava below the diaphragm
  • pT3c: Tumor extends into vena cava above the diaphragm or invades vena cava wall
  • pT4: Tumor invades beyond Gerota fascia, including direct extension to adrenal gland
Regional lymph nodes (pN)
  • pNX: Cannot be assessed
  • pN0: No regional lymph node metastasis
  • pN1: Regional lymph node metastasis
    (regional lymph nodes = hilar, caval, aortic)
Distant metastasis (pM)
  • pM1: Distant metastasis, including noncontiguous adrenal involvement
