Abstract:【 】 Objectives To select some safe, effective and convenient methods for the evaluation of dysphagia after radiotherapy for nasopharyngeal carcinoma. Methods A total of 37 patients with nasopharyngeal carcinoma in the Central Hospital of Shaoyang were selected. Video Fluoroscopic Swallowing Study (VFSS), Eating Assessment Tool (EAT-10), M.D.Anderson Dysphagia Inventory (MDADI), Repeated Saliva Swallowing Test (RSST) and Water swallowing test (WST)were used to evaluate the swallowing function of the patients, so as to seek some suitable methods for the evaluation of dysphagia after radiotherapy(chemotherapy)for nasopharyngeal carcinoma. Results Taking Video Fluoroscopic Swallowing Study (VFSS) as the gold standard, the sensitivity of Eating Assessment Tool (EAT-10) was 83.33%, the sensitivity of M.D.Anderson Dysphagia Inventory (MDADI) was 72.22%, and the specificity of Repeated Saliva Swallowing Test (RSST) was 84.21%. However, the Kappa values of these methods with gold standard are all less than 0.2, which means their consistency is low. The specificity of Water swallowing test (WST) was 78.95%, and the Kappa value was more than 0.2, which means its consistency with gold standard is better than other methods. Conclusion The Water swallowing test (WST) is relatively consistent, and can be used as a screening tool for dysphagia after radiotherapy (chemotherapy) for nasopharyngeal carcinoma, and other methods can also assist in the evaluation.
