The 5-year survival rate of advanced esophageal cancer is relatively low, and the 5-year survival rate can reach about 30%. For advanced esophageal cancer, there is no chance of cure. Because esophageal cancer according to the staging of digestive tract tumors, according to the esophageal mucosa, esophagus does not have plasma layer, divided into mucosal layer, submucosal layer, and muscular layer, if it invades into the muscular layer, it may directly invade into the peripheral organs, in this case, there is no chance of surgical treatment for the tumor patients, and we will give him the choice to choose chemotherapy or chemotherapy or radiotherapy combined. However, most Asian people, especially Chinese people, cannot tolerate radiotherapy and chemotherapy at the same time. Therefore, esophageal cancer cannot be cured, and the 5-year survival rate of advanced esophageal cancer is very low.
