Abstract
- This study aims to report on the effectiveness of voice rehabilitation following radiotherapy for laryngeal cancer in a long-term perspective, i.e., up to three years after completion of radiotherapy. The study included a total of 74 patients that were randomised into an intervention group (n = 37) or a control group (n = 37). Voice recordings with blinded assessment of voice quality with the GRBAS protocol (Grade, Roughness, Breathiness, Asthenia, Strain) and acoustic analysis was performed at baseline, 12 and 36 months following radiotherapy. Voice rehabilitation was performed in 10 sessions immediately following completion of radiotherapy. Patients also filled out the Swedish Self-Evaluation of Communication Experiences after Laryngeal cancer. The S-SECEL demonstrated statistically significant improvements in the intervention group when comparing baseline and 36 months, and no changes in the control group. Acoustic measures did not reveal any significant changes. The perceptual analysis demonstrated that when comparing the changes within the groups between baseline and 36 months there were statistically significant differences between the intervention and control group regarding the voice qualities Roughness, Breathiness and Strain. In the control group, 50% demonstrated deterioration in roughness, while in the intervention group only 7% deteriorated during this time. In Breathiness and Strain, 57 and 50%, respectively, improved in the intervention group, while only 32% and 23% improved, respectively, in the control group. Voice rehabilitation following radiotherapy for laryngeal cancer demonstrate positive effects in patient reported outcomes and perceptual measures of voice quality, and the effects remain up to three years following radiotherapy.
