Long-Term Voice and Swallowing Outcomes for Oral and Oropharyngeal Cancer Following Primary or Adjuvant Chemoradiation

Abstract

Objective:

Chemoradiation (CRT) for nonlaryngeal head and neck cancer (HNC) can lead to voice and swallowing dysfunction. The purpose of this study was to examine voice and swallowing from the patient’s perspective at least 5 years after treatment.

Design:

Patient survey.

Methods:

Twenty-eight patients treated with primary or adjuvant CRT at least 5 years ago (mean = 10.7 years, SD = 5.5, range, 5-28) completed a survey created based on previously validated questionnaires (the Patient Perception of Swallowing Function Questionnaire, PPSFQ; the Eating Assessment Tool, EAT-10; the Voice Handicap Index, VHI-10; the Voice Related Quality of Life, V-RQOL).

Results:

Patients reported some voice and swallowing dysfunction (39% of V-RQOL scores in categories of fair, poor, or worst possible and 32% of VHI-10 scores ≥20 or greater than 50% of the maximum; 39% of PPSFQ scores greater than 50% of the maximum and 32% of EAT-10 scores ≥20 or 50% of the maximum). There was a correlation between V-RQOL and VHI-10 scores (Pearson product moment correlation coefficient r = .96, calculated probability value p = 0), PPSFQ and EAT-10 scores (r = 0.87, p = 0.8 × 10⁻⁸), as well as between V-RQOL and PPSFQ/EAT-10 scores (r = .94, p = 0), VHI-10 and PPSFQ/EAT-10 scores (r = .97, p = 0).

Conclusions:

Perceived voice and swallowing dysfunction following CRT for nonlaryngeal HNC can persist or worsen beyond 5 years.
