Research Article: Analysis of the Risk Factors for Negative Emotions in Patients with Esophageal Cancer During the Peri-Radiotherapy Period and Their Effects on Malnutrition
Abstract:
Esophageal cancer (EC) is a common malignant tumor of the gastrointestinal tract, with a high incidence rate and a low survival rate. It is the sixth most common cause of death due to malignant tumors worldwide and the fourth most common cause of death due to malignant tumors in China. The annual incidence of new cases is about % of the global incidence, and the incidence rate increases every year., Because of its physiological function and anatomical location, the incidence of malnutrition in patients with esophageal cancer is higher than that in patients with other tumors. More than % of patients with esophageal cancer suffer from malnutrition to different degrees, and % of patients die because of malnutrition. The mechanism of malnutrition is complex and might be related to the special physiological function, anatomical structure, tumor-related factors such as dysphagia and obstruction, and treatment-related factors, such as gastroesophageal reflux caused by surgery and vomiting caused by the administration of chemotherapeutic drugs., Radiotherapy is an effective method of treating EC and considerably prolongs the survival of patients., However, radiotherapy has toxic side effects in patients and might also lead to malnutrition. Long-term malnutrition reduces the quality of life of patients and their tolerance to radiotherapy and decreases treatment sensitivity, resulting in prolonged hospitalization or shortened survival time, or in severe cases, treatment failure due to lack of tolerance.,
