After lung cancer has metastasized to hilar, surgical treatment, radiotherapy, targeted therapy and immunotherapy drugs need to be selected according to the severity of the disease and the physical quality of the patient. 1. Surgery: for the case that both primary and metastatic foci are small and limited, and the patient is in good physical condition, the tumor foci can be completely removed by surgery. 2. Radiotherapy: If the lesions are large, multiple and scattered, or the patient cannot tolerate surgery, radiotherapy can be chosen to kill the tumor cells and reduce the tumor foci, so as to improve the prognosis of the disease. Chemotherapy drugs include methotrexate, paclitaxel and so on. 3. Targeted drugs: Commonly used targeted drugs include gefitinib, ectinib, etc., which need to be used after genetic testing to clarify whether there is a corresponding target point. 4. Immunotherapy drugs: commonly used drugs include pembrolizumab and so on. After lung cancer has metastasized to the lung gate, patients are recommended to go to the hospital as soon as possible and actively cooperate with doctors to receive standardized treatment.
