Kidney cancer is called “kind cancer” because the prognosis of kidney cancer is relatively good, and more patients can be clinically cured. Kidney cancer consists of primary kidney cancer and secondary kidney cancer. Primary kidney cancer is the most common, which is a malignant tumor originated from renal tubular epithelial system, and clear cell carcinoma accounts for the majority of it, accounting for about 85% of renal malignant tumors. With the popularization of physical examination, most patients can be detected in early stage. 1. Early-stage renal cancer mostly refers to confined renal cancer, i.e. T1-T2N0M0 stage renal cancer (stage I-II) in TNM staging, at this time, renal tumors are usually confined to the kidneys without metastasis, and a better prognosis can be obtained after treatment. Some studies claim that the 5-year survival rate after surgery can generally reach more than 70%; 2. for locally progressive renal cancer, the comprehensive treatment plan of surgery combined with targeted therapy/immunotherapy is mostly adopted. Some studies claim that after active treatment, the 5-year survival rate after surgery is also around 50%. 3; 3. if distant metastasis has occurred in renal cancer and the prognosis becomes obviously worse, surgical treatment is usually palliative surgery for reducing tumor burden and improving survival quality. Some studies claim that its 3-year survival rate after surgery is about 50%, and 5-year survival rate is more than less than 30%. In conclusion, renal cancer is still a malignant tumor, but the prognosis is often better. It is recommended to go to regular hospitals to evaluate the condition and follow the doctor’s instructions to cooperate with the treatment, so as not to delay the condition.
