Cancer-specific survival probabilities according to a modified TNM staging system. Blue curve: All pT1 renal cell carcinoma (RCC). Green curve: All pT2 RCC. Red curve: RCC with isolated perirenal fat invasion, renal vein thrombosis, or subdiaphragm vena cava thrombosis. Violet curve: RCC with renal vein thrombosis or thrombosis within the vena cava below the diaphragm associated with perirenal fat invasion. Orange curve: RCC with adrenal gland invasion or Gerota's fascia invasion or thrombosis within the vena cava above the diaphragm. Pooled log-rank p value <0.0001. All the pairwise log-rank p values were <0.0001, with the exclusion of the comparisons between the two worst categories (log-rank p = 0.40).
