Official title

Effect of Irradiation Dose to Eustachian Tube and Surrounding Auditory Organs on the Occurrence of Radiation-induced Otitis Media in Nasopharyngeal Carcinoma Patients During Intensity Modulated Radiotherapy Era: A Prospective Cohort Study

Overview

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.

Primary outcome measures

  • Incidence of radiation-induced otitis media [Time frame: 1 year]
Secondary outcome measures (5)
  • Effect of the irradiation dose of eustachian tube, tympanum, cochlea, internal auditory tract and vestibule on the occurrence of radiation-induced otitis media [Time frame: 1 year]
  • Effect of irradiation dose in the area around of eustachian tube on the severity of ototoxicity after radiotherapy [Time frame: 1 year]
  • Effect of irradiation dose of eustachian tube on hearing injury [Time frame: 1 year]
  • Effect of different chemoradiotherapy treatment regimens on the occurrence of radiation-induced otitis media [Time frame: 1 year]
  • Correlation between radiation-induced otitis media and life quality after radiotherapy [Time frame: 1 year]

Exclusion criteria

  • Women in pregnancy or lactation.
  • Patients with significantly lower heart, liver, lung, kidney, bone marrow function and other severe medical condition.
  • Prior to radiotherapy, there is a clear underlying disease of the eustachian tube or other ear diseases.
  • Patients with otitis media before radiotherapy and have no improvement at the end of radiotherapy.
  • Patients with history of middle ear, nasal or nasopharyngeal surgery on the affected side.
  • Patients combined with congenital cleft palate and other craniofacial abnormalities.
  • Patients with histologically confirmed keratinizing nasopharyngeal carcinoma, type of WHO I.
  • Patients with recurrence and distant metastasis.
  • Patients with radiotherapy or chemotherapy before.
  • Age < 18 or age > 70.
  • Patients who changed their initial treatment regimen during the observation period due to disease progression (including tumor residual after radiotherapy, tumor recurrence, and new distant metastases).
