Squamous esophageal cancer accounts for the majority of all esophageal cancers, most of which can be treated surgically firstly by radical surgery, using traditional open-chest surgery or thoracoscopic radical treatment of esophageal cancer, which needs to be combined with adjuvant chemotherapy and radiotherapy after surgery. If the postoperative pathology indicates that the number of lymph node metastasis is relatively large, adjuvant radiotherapy is needed, otherwise, 4-6 courses of adjuvant chemotherapy are usually sufficient. Some advanced patients or elderly people who are not able to tolerate this kind of surgery can do simple radiotherapy and chemotherapy, and the effect is also good and can prolong the survival. In addition, for squamous esophageal cancer, if there is extensive metastasis, surgery is not recommended and the effect is not too good, so radiotherapy and chemotherapy can be considered, as well as further interventional treatment for metastatic lesions.
