When lung cancer bone metastasis and fracture, the treatment is divided into two parts: lung cancer bone metastasis treatment and fracture treatment. 1. Lung cancer bone metastasis: it means that the patient is already in the advanced stage of the tumor at this time, and the 5-year survival rate of advanced lung cancer is very low. It is common to have chemotherapy to control the development of bone metastasis, such as cisplatin-based chemotherapy, and also radiotherapy, bio-immunotherapy, and targeted therapy can prolong the survival time and improve the quality of life. 2. Fracture: For fracture caused by bone metastasis of lung cancer, surgical treatment or conservative treatment can be chosen according to the different degree of fracture. (1) Surgical treatment: if there are multiple ribs fractures, angular fractures, spiral fractures at the stress area, etc., and there are indications for surgery, they need to be fixed by external fixation frame or surgical internal fixation, and they can go down to the ground and have proper activities after healing. (2) Conservative treatment: if the fracture is fracture, stable fracture, etc., and the fracture symptoms are mild, conservative treatment such as plaster fixation or braking treatment should be adopted, and regular review should be conducted. Bone metastasis of lung cancer is mostly in advanced stage, so it is necessary to pay attention to regular rechecking and keep a positive mindset. In daily life, personal care should be cured, nutrition should be strengthened and excessive exercise should be avoided.
