Quality of life and voice following endoscopic resection or radiotherapy for early glottic cancer.
OBJECTIVE
To assess whether proposed voice and quality of life (QoL) outcome measures were likely to be acceptable to patients previously treated for early glottic cancer by either radiotherapy or endoscopic resection, as well as looking for differences in QoL and voice between treatments.


METHODS
Questionnaire-based cohort study.


METHODS
Secondary care, three centres.


METHODS
All patients treated for T1a or in situ glottic carcinoma between 1997 and 2003. Fifty-three patients were identified; those who had undergone salvage surgery or radiotherapy were excluded. A proportion refused to participate or could not be contacted and two patients had died of unrelated causes. Thirty-six patients completed the trial with 18 from each treatment arm.


METHODS
Quality of voice as assessed by three questionnaires, Voice Handicap Index (VHI), Vocal Performance Questionnaire (VPQ), Voice Symptom Score (VoiSS) and perceptual analysis of voice by Grade, Roughness, Breathiness, Asthenia and Strained (GRBAS) assessment of vocal recordings. Quality of life as assessed by the Hospital Anxiety and Depression Scale (HADS), University of Washington Quality of Life Questionnaire (UW-QoL), and the Functional Assessment of Cancer Therapy (FACT) questionnaire.


RESULTS
All patients included in the trial were able to complete the questionnaires; however, 19% required assistance of some kind. GRBAS assessment showed no difference between groups for any criteria. All QoL questionnaires gave equivalent good scores. All of the voice questionnaires showed no statistical difference between groups except for the emotional subscale of the VoiSS which showed a significantly better score for the radiotherapy arm (P = 0.04).


CONCLUSIONS
All outcome measures were applicable and acceptable to the patient group. Overall QoL and voice appears similar despite treatment arm, apart from the emotional subscale of the VoiSS. A randomized controlled trial is required to further assess this question.
