Conclusion: Participants would accept extra toxicity in exchange for better chances of cure, suggesting most would accept treatment intensification, including dose-escalation. Participants were more concerned about long-term than short term side effects, highlighting the need for long-term follow-up of toxicity, and for clinical decision-making to take account of individual patients’ preferences.

Keywords: patient preference; rectal cancer; dose-escalation
