Malignant renal tumor: For the survival rate of renal cell carcinoma, it is related to its stage. Some studies say that: the 5-year survival rate after radical resection of stage I renal cell carcinoma is about 94%, while stage IV patients are 0-20%. For metastatic carcinoma, the median survival period of patients in low-risk group is 20 months, and that of intermediate-risk group is 10 months, while the average survival period of patients in high-risk group is only 4 months.
