Surgery is not recommended after lung cancer metastasis, and systemic treatment such as chemotherapy is mainly used. Some types of lung cancer can also be treated with oral targeted drugs. Currently, PD-1/PD-L1 immunosuppressants are increasingly used in patients with advanced lung cancer, and some of them can also get good results. Because clinical trials have been done, compared with non-surgical resection, surgical resection of advanced lung cancer patients does not improve the survival of patients, but increases the side effects of surgery and even shortens the life of patients, so at this time, systemic therapy is the main treatment and local radiotherapy of lung lesions can also be considered when systemic lesions are controlled.
