Most kidney tumors can be cured. Although renal cell carcinoma is also a malignant tumor, the effect of early surgical treatment of renal cell carcinoma is very good, many patients can achieve the curative effect, and there is basically no recurrence after resection. If it develops to the advanced stage of renal cancer, it will be very difficult to treat. Even if it is surgically removed, it is more likely to recur.

1. Hamartoma: enucleation or partial nephrectomy is feasible. Nephrectomy can be considered for patients with large tumor, damaged renal structure and loss of function. There is basically no recurrence after surgery, and even if it recurs, it can be operated again.

2. Radical nephrectomy should be performed as soon as possible after the diagnosis of renal cancer: if it is an early renal tumor, the possibility of recurrence is very low. If it is in the middle and late stage, there is a great possibility of recurrence.

3. Renal pelvis cancer: Pathological differences are great. Some patients have a low possibility of recurrence after surgery, but many patients relapse soon after surgery. It is reported that the 5-year survival rate of patients after operation is 30-60%.

4, nephroblastoma: surgery and radiotherapy and chemotherapy are very effective, which is the best effect among children's malignant solid tumors. Postoperative radiotherapy can greatly reduce the recurrence rate. The 2-year survival rate is about 60-90%. At present, it is considered that no recurrence for 2-3 years is the cure.

Whether renal tumor can recur after resection mainly depends on pathological type, malignant degree, lymph node metastasis, early surgical treatment, radiotherapy and chemotherapy, etc. In addition, the general physical condition and psychological factors of patients also affect the probability of postoperative recurrence.
