Patient：Description of disease (onset time, main symptoms, hospitalization, etc.): My father was 47 years old and got esophageal cancer. After examination, he said that the cancer had not spread in the middle stage, but the location was relatively close to blood vessels, so many doctors suggested not to do surgery. I would like to know how sure I can extend my life if I receive treatment at your hospital. Hospital: Because the description is too simple, I can only give a general answer. 1. If locally advanced (mid-stage) esophageal cancer cannot be operated, and the treatment is mainly radiotherapy, the probability of 5-year survival is about 30%. 2.If the physical condition is better, simultaneous radiotherapy is recommended, which can improve the local control rate and survival rate. 3.Esophageal cancer often affects eating, so special attention should be paid to nutritional supplementation to create strong conditions for the next treatment.
