- TNM Staging of Renal cell carcinoma (illustrated).

TNM Staging of Renal cell carcinoma.
Primary tumor (T):-

T0: No evidence of primary tumor
T1: Tumor 7 cm or less in the largest dimension, Tumor is confined to the kidney (i.e no penetration through the capsule).
T2: Tumor greater than 7 cm in the largest dimension, Tumor is confined to the kidney (i.e no penetration through the capsule).

T3a: Tumor penetrates through the kidney capsule into the surrounding fat or the adrenal gland, but not through Gerota's fascia. 


T3b: Tumor extends into renal vein(s) or vena cava below diaphragm.

T3c: Tumor extends into vena cava above diaphragm.

T4: Tumor invades beyond Gerota's fascia.



N - Regional lymph nodes
N0: No regional lymph node metastasis
N1: Metastasis in a single regional lymph node
N2: Metastasis in more than one regional lymph node


M - Distant metastasis
M0: No distant metastasis
M1: Distant metastasis

  1. Renal cell cancer is one of the few tumors in which well-documented cases of spontaneous tumor regression in the absence of therapy exist, but this occurs very rarely and may not lead to long-term survival. The incidence of Renal cell cancer seems to be increasing, though it isn't clear why. The exact cause of renal cell cancer has not been determined but Smoking and misuse of certain pain medicines probably can affect the risk of developing renal cell cancer.
