Treatment plan for esophageal cancer in 80 years old should be made according to specific conditions, including conservative treatment, surgery and radiotherapy. 1. Conservative treatment: 80 years old people belong to high age, patients with esophageal cancer should assess the basic condition of the patients and the specific clinical staging of the tumor, patients with poor physical quality and middle or late stage esophageal cancer should focus on symptomatic treatment to alleviate the pain of the patients and improve the quality of life. 2. Surgical treatment: For patients with good physical quality, early or middle stage esophageal cancer with surgical indication and no contraindication to surgery, surgical treatment can be performed. Cardiopulmonary function should be evaluated before surgery to prevent serious complications after surgery, and chemotherapy or radiotherapy should be given according to specific conditions. 3.Radiotherapy Preoperative neoadjuvant radiotherapy is recommended for patients with cTis-2N1-3M0 or cT3-4a N(any) M0 stage esophageal cancer who intend to undergo surgery in order to improve radical resection rate, complete pathological remission rate, local tumor control rate, and thus improve postoperative long term survival; radical simultaneous radiotherapy is recommended for those who are not planning to undergo surgery or refuse to undergo surgical treatment. For those who are non-radical resected (R1 or R2) by pathological evaluation after surgery, or those who are RO resected but are (y)pT4 N(any) M0 stage, postoperative adjuvant synchronous radiotherapy can be considered according to the recovery of the patients. The treatment of esophageal cancer in the elderly is difficult, and it is necessary to understand both the severity of the disease and the underlying disease to develop a specific treatment plan.
