Can kidney-saving surgery completely cure kidney cancer?

After being diagnosed with kidney cancer, patients often hope to save their kidneys, but at the same time they worry that kidney-saving surgery cannot completely cure kidney cancer. In fact, whether kidney-saving surgery can completely cure kidney cancer depends on the progression of the patient's condition.

With the significant increase in the detection rate of early renal cancer, the application of kidney-preserving surgery in clinical practice has become more and more common. A large amount of evidence-based medicine at home and abroad has confirmed that for kidney tumors smaller than 4 cm, as long as the tumor is in the right location, it can be completely treated through kidney-preserving surgery, and its effect is the same as radical surgery. The latest information shows that kidney-preserving surgery can completely treat patients with renal cancer of 4cm to 7cm who meet the surgical conditions. Of course, kidney-preserving surgery has certain indications, and the requirements for the doctor's experience and technology are relatively high, and it may also increase the incidence of some complications, but at present, the above conditions are all controllable.

In addition, some patients and their families believe that there is no need for surgical treatment of advanced renal cancer that has already metastasized. Indeed, it is indeed unnecessary to perform relatively invasive surgical treatments on many advanced metastatic tumors. However, renal cancer has some particularities. For some renal cancer patients with distant metastases such as lymph node or lung metastases, if the patient's overall condition permits and the renal tumor removal is not very difficult, it is still necessary to choose to remove the primary lesion of the renal tumor, or even the distant metastatic lesion, which is helpful for delaying the patient's survival time and improving the effect of adjuvant therapy.
