The Relationship Between Voice Handicap Index and Voice-Related Quality of Life in Patients with Early Laryngeal Cancer.

Abstract

Voice production can be affected in early laryngeal cancer. The purpose of this study was to investigate the correlation between Voice Handicap Index (VHI) and Voice-Related Quality of Life (V-RQOL) among patients with early laryngeal cancer. Twenty-seven patients with early laryngeal cancer (T1, T2) and a mean age of 59.35 ± 7.77 years who were visited in Amir-Alam hospital, took part in this study. After a diagnosis of early laryngeal cancer by a laryngologist, the patients filled out the Persian versions of the VHI and V-RQOL questionnaires. The results showed the mean total score of VHI and V-RQOL were 65.94 ± 14.21 and 48.64 ± 9.75% in patients with early laryngeal cancer, respectively. These results indicated the total and subscales' scores of VHI increased while the scores of VRQOL decreased. The Pearson correlation between total scores of the VHI and V-RQOL was - 90. Also, there was a negative significant correlation between total and subscales' scores of VH and VRQOL (r Pearson= -0.46 to -0.90, p ≤ 0.05). Our findings demonstrated decreased quality of life related to voice in patients with laryngeal cancer who were in the early stages of tumor growth (T1, T2). Regarding the high negative significant correlation between results of VHI and V-RQOL in patients with early laryngeal cancer, both questionnaires can be used instead of each other for saving time in voice clinics.
