Kidney cancer is prone to bone metastasis. Generally, patients with bone metastasis from cancer are considered to be dead and prepared to wait for death. In fact, the concept of metastatic bone tumor has changed greatly nowadays. For single bone metastasis of kidney cancer in the extremities or spine, it is recommended to try to remove it by radical surgery, which can obtain good results. Generally pelvic bone metastases are less effective in treatment, unless surgery is considered for palliative pain reduction. In any case, bone metastasis of kidney cancer is not a dead end or waiting for death, but needs to be treated actively, because the prognosis of surgery for bone metastasis of kidney cancer is still relatively good.
