Esophageal cancer is a common gastrointestinal tumor that kills about 300,000 people worldwide each year. Its incidence and mortality rates vary greatly from country to country. China is one of the regions with high incidence of esophageal cancer in the world, with an average of about 150,000 deaths per year. There are more men than women, and the age of onset is mostly above 40 years old. The typical symptom of esophageal cancer is progressive difficulty in swallowing, firstly, it is difficult to swallow dry food, then semi-liquid food, and finally, water and saliva cannot be swallowed. Early symptom of esophageal cancer I: distention or slight pain behind the sternum. This symptom does not occur continuously, but intermittently or worsens after exertion and when eating quickly. This is because the esophagus itself is peristaltic at any time, and the symptoms will appear only when the peristaltic movement reaches the lesion. Early symptoms of esophageal cancer II: Foreign body sensation when swallowing food. During the process of swallowing food (especially dry and hard food) passing through the lesion area (the lesion is small) may produce a foreign body sensation, and it is often fixed in one part, some patients describe it as a feeling that they can never finish swallowing something. Because the symptoms are mild and intermittent, it is easy to be neglected by patients. Early symptom of esophageal cancer III: Stagnation or stuttering sensation of swallowing, i.e. the patient seems to have the feeling of stagnation and stuttering in a certain area when swallowing food, which is not continuous and only becomes obvious gradually after the development of lesion. Early symptom of esophageal cancer IV: feeling of distension or constriction in the chest, often accompanied by dryness in the throat. Patients complained that there is a kind of stuffy phenomenon in the front of chest, which seems to be blocked by an object and makes the chest feel constricted, especially when swallowing food, but it does not affect normal life and work. Early symptom 5 of esophageal cancer: fullness and light pain in the heart fossa, subxiphoid process or upper abdomen, which is more obvious when eating dry food, but it does not occur every time but intermittently. This is often an early symptom of cardia cancer. The above early symptoms usually last for more than 3 months, and when they occur frequently and persistently and worsen, they are no longer early. Before radiotherapy, the first thing is to do the ideological work of patients, so that they can understand radiotherapy and avoid tension and fear, and secondly, to improve the general condition, pay attention to nutrition allocation, improve local condition and avoid local infection. Surgical treatment: surgical resection is mainly used for resection of T1 stage lower esophageal cancer, and for patients in the middle stage, palliative surgery can also be done. Radiotherapy: It is the first choice for patients with middle and late stage esophageal cancer who have lost the chance of surgical treatment. Chemotherapy: For patients who cannot undergo surgery or radiotherapy, the use of chemotherapy can relieve symptoms and shrink tumors. Diversified treatment: Diversified treatment can improve the overall survival rate of esophageal cancer patients; preoperative neoadjuvant chemotherapy and radiotherapy can both improve the survival rate of esophageal cancer patients. Traditional Chinese medicine treatment: It should be based on the principle of evidence-based treatment, together with disease-specific medicine. Other treatments: there are acupuncture treatment of foot three li, Neiguan, epigastric, tiantu and taichong points. Cutting treatment method, enlightenment therapy, etc.
