However, preoperative examination should be perfected and obvious contraindications to surgery should be ruled out before surgery is performed. If the risk of surgery is greater than the benefit of surgery, or there are contraindications to surgery, then radiotherapy is recommended. 1. If the patient is 80 years old, has early esophageal cancer, and there is no obvious contraindication to surgery in the preoperative examination, and the cardiopulmonary, hepatic and renal functions can tolerate anesthesia and surgery, surgery is generally preferred. 2. If the patient is 80 years old and has middle-late esophageal cancer, although there is no obvious contraindication to surgery in the preoperative examination, and the heart, lung, liver and kidney functions can tolerate the anesthesia and surgery, the anesthesia risk and surgical risk assessed before the surgery are relatively large, and it is necessary to consider the risk of the surgery and the benefit of the surgery, and the surgical treatment can be considered as well as other treatments, such as radiation therapy, can be considered. 3. If the patient is eighty years old and has advanced esophageal cancer with obvious contraindications to surgery, esophageal cancer surgery cannot be performed. Whether the patient is eighty years old and can undergo esophageal cancer surgery, it is recommended to go to the Department of Thoracic Surgery of regular hospital for further consultation.
