The manifestations of esophageal cancer metastasis include progressive dysphagia, retrosternal pain, hoarseness and so on. Metastasis of esophageal cancer mostly means that the patient is in the middle or late stage of the disease, and the metastasis of cancer cells will induce the body to have progressive dysphagia, persistent pain in the retrosternal or interscapular region of the back, choking and coughing and other symptoms. However, when the cancer cells metastasize to the larynx, the patient will suffer from hoarseness, and when the cancer cells metastasize to the trachea, the patient will suffer from shortness of breath, dry cough, dyspnea, hemoptysis and other abnormalities. When esophageal cancer metastasizes to large blood vessels, it is easy to cause hemorrhage leading to shock and even death. When cancer cells invade phrenic nerve, it is easy to cause hiccups. Besides the above symptoms, patients with metastatic esophageal cancer are also prone to emaciation, anemia, malnutrition, cachexia, massive ascites, etc., which seriously affect their health and quality of life. It is suggested that patients with metastatic esophageal cancer should actively cooperate with doctors in treatment, and they should also go to doctors for regular review so as to adjust the treatment plan according to the changes of their conditions. For those who have difficulty in feeding through mouth, enteral nutrition or parenteral nutrition is feasible to meet the needs of the body.
