Nasopharyngeal Carcinoma, Radiation-induced Otitis Media
Brief summary
This is an observational cohort study to investigate the incidence of radiation-induced otitis media, changes in tubal function and hearing in newly diagnosed nasopharyngeal carcinoma patients without metastasis at multiple time points from baseline to 1 year after radiotherapy.
Detailed description
Patients with newly diagnosed non-metastatic nasopharyngeal carcinoma (AJCC 8th) will be recruited. The incidence of radiation-induced otitis media, eustachian tube function and hearing level in nasopharyngeal carcinoma patients will be prospectively evaluated by magnetic resonance imaging, otoscope, pure tone audiometry, acoustic immittance test and the Eustachian Tube Dysfunction Questionnaire (ETDQ-7) before treatment and serially up to 1 year after radiotherapy. The quality of life of patients will be evaluated before treatment and serially up to 1 year after radiotherapy. The incidence of radiation-induced otitis media, the changes of eustachian tube function and hearing level, together with the influencing factors, in nasopharyngeal carcinoma patients after induction chemotherapy and concurrent chemoradiotherapy will be investigated.
