Template:Renal tumor staging

By AJCC 8th edition:

Stage	TNM	Description
	Tx, N0, M0	Tumor cannot be assessed
	T0, N0, M0	No evidence of primary tumor
I	T1, N0, M0	Tumor ≤7 cm; limited to kidney
	T1a, N0, M0	Tumor ≤4 cm; limited to kidney
	T1b, N0, M0	Tumor 4-≤7 cm; limited to kidney
II	T2, N0, M0	Tumor >7 cm; limited to kidney
	T2a, N0, M0	Tumor 7-≤10 cm; limited to kidney
	T2b, N0, M0	Tumor >10 cm; limited to kidney
III	T3, N0, M0	Tumor extends to major veins or perinephric tissue but not into ipsilateral adrenal gland nor beyond Gerota's fascia
	T3a, N0, M0	Tumor grossly extends into renal vein or its segmental branches, or tumor invades the pelvicalyceal system, or tumor invades perirenal and/or renal sinus fat but not beyond Gerota's fascia
	T3b, N0, M0	Tumor grossly extends into vena cava below the diaphragm
	T3c, N0, M0	Tumor grossly extends into vena cava above the diaphragm or invades the wall of the vena cava
	T1-T3, N1, M0	The main tumor can be any size and may be outside the kidney, but it has not spread beyond Gerota’s fascia. The cancer has spread to regional lymph nodes (N1) but has not spread to distant lymph nodes or other organs (M0).
IV	T4, any N, M0	Tumor invades beyond Gerota's fascia
	Any T, any N, M1	Tumor has spread to distant lymph nodes and/or other organs.
