Esophageal cancer (esophageal cancer) without food is able to be infused with nutrient solution, through which the infusion of nutrients can improve the patients’ malnutrition, hypoproteinemia and other conditions to a certain extent. For esophageal cancer patients, the tumor blocks the lumen of esophagus so that the patients cannot eat, and they are prone to malnutrition such as hypoproteinemia, etc. In order to improve this nutritional status so that they can tolerate anti-tumor treatments such as surgery, radiotherapy and chemotherapy, various kinds of nutrients can be supplemented through intravenous infusion in general. In addition to nutritional supplementation through infusion of nutritional solution, the clinic can also establish nutritional pathways through the placement of gastrointestinal nutritional tubes, esophageal stents and other ways, so as to replenish the nutrients that the human body needs on a daily basis. It is recommended that patients go to a regular hospital as soon as possible to consult a professional doctor.
