Identification of adolescents and young adults' preferences and priorities for future cancer treatment using a novel decision-making tool.

The MyPref-calculated preferences varied by individual and differed from initial rank ordering. Additionally, there was variability in how individuals defined and prioritized treatment-related factors. This novel tool may be a useful way to engage AYAs and their PTPs in discussions around preferences for treatment and prepare AYAs for future decision making. We plan to evaluate this tool longitudinally to evaluate the impact on actual treatment decisions.
