PURPOSE: Laryngeal cancer treated by radiotherapy results in many patients being left with an abnormal voice long-term. This prospective study aims to report efficacy of voice rehabilitation 5years postradiotherapy completion.
METHODS: Seventy-seven patients were randomized into an intervention group (n = 37) or a control group (n = 40). Voice rehabilitation was administered postradiotherapy. Patients were followed at baseline, 12- and 60-month postradiotherapy with voice recordings assessed using GRBAS protocol (Grade, Roughness, Breathiness, Asthenia, Strain). Patients filled in the European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire Head and Neck 35 (EORTC QLQ-HN35) and the Swedish Self-Evaluation of Communication Experiences after Laryngeal Cancer (S-SECEL).
RESULTS: There were no statistically significant differences between the intervention and control group in scores reported on EORTC QLQ-HN35, S-SECEL or in perceptual evaluation at study end-point. The intervention group reported an improvement in EORTC QLQ-HN35 Speech between baseline-60months postradiotherapy. No significant changes between 12-60months were observed. The control group demonstrated significant improvement in domains Pain, Senses, Speech, Social eating and Sexuality from baseline-60months postradiotherapy, of which only Speech showed a statistically significant change between 12-60months postradiotherapy (P = 0.02). Both groups reported improved S-SECEL scores from baseline-60months, with no significant dynamic between the 12- and 60-month follow-up.
CONCLUSION: Previously observed positive effects of voice rehabilitation on patient communicative skills and perceptual evaluation are no longer noticeable at 5-year post voice therapy completion. Nevertheless, patients receiving voice rehabilitation experience a greater improvement within the first year, which in the control group takes a corresponding 5years.
