Previously, we briefly introduced the diagnosis methods of kidney tumor, and next, we will briefly explain the main treatment methods of kidney tumor. The main treatment means of kidney cancer include: 1.Surgical treatment. 2.Immunotherapy. 3.Chinese medicine. 4.Radiation and chemotherapy. 5. Drug therapy. With the development of diagnostic imaging, more and more kidney cancers have been diagnosed at early stage, and the current trend at home and abroad is indeed minimally invasive treatment. However, the traditional surgical treatment still cannot be replaced. The surgical treatment of kidney tumor mainly includes: radical kidney cancer surgery and kidney unit preservation surgery. Radical kidney cancer surgery is mainly divided into: open surgery and laparoscopic surgery. A large amount of data at home and abroad show that both surgical methods can achieve satisfactory results, depending on the patient’s decision and the surgeon’s skill level. Renal preservation surgery mainly includes: partial nephrectomy, renal tumor ablation, and ultrasonic high energy focus. For kidney tumors less than 4 cm, both open and laparoscopic partial nephrectomy have been developed more perfectly, and there is no significant difference in the efficacy between the two surgical methods, while laparoscopic surgery has become the mainstream of surgical treatment for kidney tumors today because of the advantages of less damage and shorter hospital stay. At present, several domestic units have started to carry out robotic surgery, but it is still in the initial stage. With the improvement of people’s awareness of minimally invasive surgery and the increase of early kidney cancer diagnosis, ablation of kidney tumor and high-energy focusing are developing rapidly. Ablation: In short, it is to kill tumor cells and tissues through local temperature change, including radiofrequency ablation and cryoablation; and both of these methods include transdermal and transabdominal approaches. The main principle of high-energy ultrasound focusing is also similar to ablation, but the equipment is replaced by a high-energy ultrasound probe. These newly developed minimally invasive means have been available abroad for more than a decade, while in China it has been about 5 years in the past. It is now generally accepted at home and abroad that early renal tumors less than 2cm can achieve the same effect as kidney preservation surgery through ablation. Although some international units also perform ablative surgery for tumors less than 4 cm, the efficacy still needs to be proved by large samples. Since most kidney cancers are not sensitive to traditional radiotherapy, in addition to surgery, immunotherapy can also be combined to improve the immunity of patients. For such patients, it is currently advocated to perform resection of primary foci + targeted therapy. After a period of targeted drug therapy, some patients have significantly reduced the size of kidney tumor or metastases and can undergo resection of metastases or primary foci. However, the efficacy of targeted drug therapy varies from person to person, and there are certain toxic side effects, and some new targeted drugs need to be further researched and developed.
