The treatments for lung cancer spreading to lymph nodes include surgery, radiotherapy and chemotherapy, etc., which need to be analyzed according to the metastasis. Lung cancer spreading to lymph nodes mainly depends on whether it is regional metastasis or distant lymphatic metastasis, as well as the number and size of metastasis, and then it can be treated by surgery, radiotherapy, chemotherapy and targeted therapy. If the metastasis is only in the hilar and mediastinal regions, it is basically in the middle stage, and as long as surgery is possible, surgical resection is recommended, and postoperative treatment is supplemented with radiotherapy and chemotherapy. If distant lymph node metastasis occurs, it is difficult to perform surgery in the advanced stage, and the treatment is still radiotherapy, chemotherapy, targeted therapy, immunotherapy and other comprehensive treatment to prolong the patient’s survival time.
