I think the key is the pathological type. You can go to the Bone Oncology Department of Jishuitan Hospital to see if you can do a biopsy, where you have more experience. If the symptoms of bone metastasis are serious and the risk is high, radiotherapy can be given first. As for chemotherapy, we need to wait for pathology.

(Dr. Zhao Jun from Beijing Cancer Hospital solemnly reminds me that because I can't see the patient face to face, I can't fully understand the condition. The above suggestions are for reference only. Please go to the hospital for specific diagnosis and treatment under the guidance of a doctor! )
