Abstract

Background - The purpose of this study was to use time trade-off to assess the factors influencing patients' decisions in advanced laryngeal cancer. Time trade-off is a well-established method of assessing how individuals value a particular health state. Methods - We developed vignettes depicting life after chemoradiotherapy or laryngectomy. One hundred fourteen participants ranked them, assigned utility values, and rated the importance of survival on treatment choice. Results - Chemoradiotherapy was preferred by 62% and laryngectomy by 38%. Chemoradiotherapy optimal outcome had the highest mean utility value (0.64) followed by total laryngectomy optimal outcome (0.56). Total laryngectomy poor outcome (0.33) was equivalent to chemoradiotherapy poor outcome (0.32).The average survival advantage required for a participant to change their preferred choice was 2.1 years. Conclusion - The functional treatment outcome had a greater effect on health state utility values than treatment modality. In many individuals, larynx conservation may not be the primary consideration in treatment preference.
