A Mucosal Contouring Method Based on Swallowing-induced Breakthrough Pain for Radiation-induced Oropharyngeal Mucositis

Summary

The performance of the predictive models for severe oropharyngeal mucositis established using current oral mucosal contouring method was unsatisfactory in nasopharyngeal carcinoma (NPC). Whereas the predictive model of a mucosal contouring method based on swallowing-induced breakthrough pain exhibited better overall performance. The aim of this prospective, multicenter, observational study was to further explore the predictive efficacy of this mucosal delineation method for radiation-induced oropharyngeal mucositis in NPC.
