Special issues in the treatment of renal cancer

In recent years, kidney cancer has become one of the major diseases that endangers society and human health, and it has brought great pain and distress to humans. In order to reduce the incidence of kidney cancer, we humans should master the special issues in kidney cancer treatment:

(1) Kidney cancer surgery that preserves kidney tissue: Kidney cancer surgery that preserves kidney tissue can be considered for cases such as bilateral kidney cancer or solitary kidney cancer and poor contralateral kidney function, such as renal vascular hypertension, kidney stones, kidney tuberculosis, and ureteral stenosis. Kidney cancer that is small (<3 cm in diameter) and located at the edge of the kidney can also be considered for kidney tissue preservation surgery. The surgical method is partial nephrectomy. The tumor can also be removed by puncture.

(2) Inferior vena cava tumor thrombus: Renal cancer is prone to tumor thrombus in the renal vein and inferior vena cava. In recent years, it is believed that if no local or distant metastasis is found, the tumor thrombus in the vein can be removed at the same time during radical renal resection, or the tumor thrombus in the inferior vena cava can be removed, and the prognosis is still good. During surgery, the inferior vena cava should be blocked above the level of the thrombus to avoid fatal pulmonary embolism. If the thrombus extends to the heart, the inferior vena cava can be blocked in the pericardium and then the inferior vena cava can be opened to remove the thrombus.

(3) Local spread of renal cancer invades adjacent tissues and organs: This is a difficult problem in the treatment of renal cancer. Complete surgical removal of the tumor and its affected tissues is the only cure. The 5-year survival rate for such patients is only 5%. Local spread of renal cancer may be accompanied by pain because the tumor invades the posterior abdominal wall, sacrospinal muscles and nerve roots. Direct infiltration of the liver by renal cancer is relatively rare. Intrahepatic metastasis is more common than direct infiltration of the duodenum and pancreas. Involvement is almost impossible to cure. Although there is distant metastasis, most of the time, the primary kidney can be removed as long as surgery is possible. The metastatic lesions can still achieve a fairly long survival rate. After the diseased kidney is removed, the hematuria and pain are also eliminated, which is worthwhile.

The above are the special issues in the treatment of kidney cancer.
