Lung cancer patients with lymph node metastasis should adopt multidisciplinary comprehensive treatment, which mainly includes surgery, radiotherapy and drug therapy. 1. Surgery: Lung cancer patients with lymph node metastasis are usually in middle or late stage, but some of them can still receive surgery. In the case of localized lymph node metastasis without distant metastasis, surgery can achieve good therapeutic effect, supplemented by chemotherapy or targeted therapy after surgery. 2. Radiotherapy: For patients with inoperable lymph node metastasis, radical radiotherapy can be accepted. Synchronized radiotherapy and chemotherapy can also enable some patients to achieve the goal of radical treatment. 3. Drug therapy: even if lymph node metastasis occurs in lung cancer patients, chemotherapy, molecular targeted therapy, immunotherapy and other drug treatments can be used. Even if lymph node metastasis occurs, lung cancer patients need to implement appropriate treatment plan according to clinical staging, and should actively cooperate with the treatment regardless of their individual conditions.
