Lymph node metastasis of lung cancer requires the best treatment plan according to patients’ specific conditions, which includes surgical resection, radiotherapy, targeted drug therapy, chemotherapy and immunotherapy. 1. Surgical resection: in early stage of lung cancer, especially non-small cell lung cancer, if there are indications for surgery and the patient’s general condition is good, the optimal solution is surgical resection, and the resection scope includes the mass and the corresponding lymph node groups. 2. Radiotherapy: Radical radiotherapy can be chosen for lung cancer combined with lymph node metastasis if the stage is early, or synchronized radiotherapy after systemic treatment if the stage is late. 3. Targeted drug therapy: for non-small cell lung cancer patients with lymph node metastasis, if surgical resection is not possible, tumor gene test is preferred, and if there are mutations in the driver genes and corresponding targeted drugs, targeted drug therapy can be chosen. 3. Chemotherapy and immunotherapy: advanced lung cancer patients with good general condition can choose platinum-containing double-drug systemic chemotherapy or chemotherapy combined with immunotherapy. Precautions: If lung cancer with lymph node metastasis is diagnosed, the patient should consult the doctor in time, and the doctor will formulate the optimal plan according to the pathological type of lung cancer, staging and general condition of the patient.
