Health-related Quality of Life as Studied by EORTC QLQ and Voice Handicap Index Among Various Patients With Laryngeal Disease

SummaryObjectivesPatients with voice-related disorders are often treated by a multidisciplinary team including assessment by patient-reported outcome measures. The present paper aims at documenting the importance of including general health-related quality of life (HRQoL) measures to clinical investigations.Study designThe participants (N = 80 larynx cancer, N = 32 recurrent palsy, N = 23 dysfunctional, N = 75 degenerative/inflammation, N = 19 various) were included consecutively at the laryngology clinic at Haukeland University Hospital. In addition, HRQoL data were included from one national group with laryngectomies (N = 105), one group with various patients formerly treated for head and neck squamous cell carcinoma (N = 96), and one population-based reference group (N = 1956).MethodObtained were the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ), the Voice Handicap Index (VHI), and the Eysenck Personality Inventory (EPI) neuroticism scores.ResultsBy analysis of variance, we have determined significant dependence of groups analyzing the sum global QoL/health index (F = 9.47; P <0.001), the functional HRQoL sum score (F5,2373 = 7.14, P <0.001), and the symptom sum HRQoL scores (F7,2381 = 8.13; P <0.001). In particular, patients with recurrent palsy and laryngeal cancer had lowered HRQoL. At the index levels, in particular dyspnea scores, were scored depending on larynx disease group (F7,2288 = 24.4; P <0.001). The VHI score correlated with the EORTC H&N35 “speech” index with a common variance of 52%. VHI scores correlated with level of neuroticism with 8% common variance (P <0.001) and EORTC scores with 22% (P <0.001).ConclusionIn particular, among patients with voice-related disease, those with recurrent palsy and laryngeal cancer had lower HRQoL. Furthermore, the HRQoL and VHI scores were inversely tied to neuroticism.
