The vast majority of kidney tumors can be cured. Although kidney cancer is also a malignant tumor, the effect of surgical treatment for early stage kidney cancer is very good, and many patients can achieve the effect of cure and basically no recurrence after resection. If the kidney cancer is advanced, it will be very difficult to treat, and even if it is surgically removed, there is a greater possibility of recurrence. 1. Malignant tumor: enucleation or partial nephrectomy is feasible. If the tumor is large, the kidney structure is destroyed and the function is lost, nephrectomy can be considered. Basically, it will not recur after surgery, and even if it recurs, it can be operated again. 2. Radical nephrectomy should be performed early after the diagnosis of kidney cancer: if it is early stage kidney tumor, the possibility of recurrence is very low. If it is middle or late stage, the possibility of recurrence is very high. 3. Renal pelvic carcinoma: there are large pathological differences, and some patients have low possibility of recurrence after surgery, but many patients recur soon after surgery. Reports suggest that patients have a 5-year survival rate of 30-60% after surgery. 4.Nephroblastoma: The effect of surgery and radiotherapy is very good, and it is the best among pediatric malignant solid tumors. The 2-year survival rate is about 60-90%, and the current view is that 2-3 years without recurrence is considered as a cure. Whether a kidney tumor can recur after resection mainly depends on the pathological type, malignancy degree, lymph node metastasis of the kidney tumor, whether to perform surgery at an early stage, whether to take radiotherapy and other adjuvant treatment measures, etc. In addition, the general physical condition of the patient and the psychological factors of the patient also affect the chances of recurrence after surgery.
