Esophageal cancer that has metastasized to the lymph can be surgically removed if surgery can be done. In addition to removal of esophageal tumor, regional lymph node removal is also required. After surgery, according to the pathological stage, if lymph node metastasis is identified, postoperative local radiotherapy and systemic chemotherapy are also needed. If the regional lymph nodes are already very large and have invaded the surrounding trachea, thoracic aorta and other important organs, it is impossible to remove them surgically, then local radiotherapy can be chosen, and if the patient can tolerate it, simultaneous radiotherapy and chemotherapy can also be performed, which is the most effective. Some lymph nodes of cervical esophageal cancer metastasize, and it is sometimes difficult to remove all the cancer cells completely.
