Stage III Renal Cell Cancer |
C89302 |
NCI Thesaurus |
Stage III includes: (T1 or T2, N1, M0); (T3, N0 or N1, M0). T1: Lesions have been divided into T1a and T1b. T1a is defined as tumor 4 cm or less in greatest dimension, limited to the kidney. T1b is defined as tumor greater than 4 cm but not more than 7 cm in greatest dimension, limited to the kidney. T2: Lesions have been divided into T2a and T2b. T2a is defined as tumor more than 7 cm but less than or equal to 10 cm in greatest dimension, limited to the kidney. T2b is defined as tumor greater than 10 cm, limited to the kidney. T3: Tumor extends into major veins or perinephric tissues, but not into the ipsilateral adrenal gland and not beyond Gerota's fascia. Lesions have been divided into T3a, T3b, and T3c. T3a: Tumor grossly extends into the renal vein or its segmental (muscle containing) branches, or tumor invades perirenal and/or renal sinus fat but not beyond Gerota's fascia. T3b: Tumor grossly extends into the vena cava below the diaphragm. T3c: Tumor grossly extends into the vena cava above the diaphragm or invades the wall of the vena cava. N0: No regional lymph node metastasis. N1: Metastasis in regional lymph node(s). M0: No distant metastasis. (AJCC 7th ed.) |
