Whether bone metastases occur and still need treatment cannot be generalized, but needs to be judged in the context of the specific situation. If the treatment can improve the clinical symptoms of the patient, improve the quality of his survival or prolong his survival time, then treatment can be carried out. The common situations are as follows: 1. If the patient only has isolated metastases that do not have a large impact, the primary lesion can be surgically removed, which can effectively relieve the symptoms produced by bone metastases, improve the prognosis and prolong life, and should be reviewed regularly to prevent recurrence; 2. If the bone metastases cause pathological fractures in the limbs, resulting in a significant decline in the patient’s living status, local tumor removal can be performed and Internal fixation stability surgery can be performed to reduce pain, improve patients’ quality of life and prolong their survival time; 3. If spinal vertebral metastases compress spinal nerves, resulting in paraplegia and nerve root pain, doctors should assess patients’ survival time. If the survival time is long, the patient should be treated actively, which can reduce the manifestation of paraplegia on one hand and improve the walking function of the patient on the other hand and reduce the difficulty of rehabilitation care; 4. When the patient has multiple bone metastases, the condition is already very serious, so the treatment should be aimed at improving pain, preventing, reducing or postponing the occurrence of orthopedic complications, improving the quality of life and relieving the patient’s pain as much as possible. Therefore, when a patient has bone metastases, if the treatment can relieve the patient’s pain or prolong the life span or even return to normal, the patient should actively cooperate with the treatment. If multiple bone metastases occur, it should also be judged by the doctor whether to carry out treatment.
