Patient: How long can I usually live with bone metastasis of lung cancer? Can it be treated by surgery again? Doctor: The average survival time of lung cancer bone metastasis patients is 6 – 10 months, and the main treatment is chemotherapy and molecular targeted drug therapy. In case of multiple bone metastases, local radiotherapy is feasible. Surgery is required when the metastases in bone cause fractures or will cause fractures, and when spinal metastases cause spinal instability or nerve compression, then surgery is appropriate. The purpose of surgical treatment is mainly to reduce the patient’s pain and indirectly prolong the patient’s life.
