Use of a Decision Aid to Resolve Uncertainty About Radioactive Iodine Treatment in Patients With Intermediate Risk Thyroid Cancer

United States408 participantsStarted 2025-08-06

Plain-language summary

The goal of this study is to learn if a decision aid (DA) website helps people with thyroid cancer make informed decisions about radioactive iodine (RAI) treatment. The main questions it aims to answer are: - Does the decision aid help participants understand the risks and benefits of RAI treatment? - Does it help participants make choices that reflect what matters most to them? - How does the decision aid compare to usual care in supporting patients through this decision? Participants who have been recently diagnosed with intermediate-risk differentiated thyroid cancer (DTC) will be randomly assigned to one of two groups. One group will receive a special decision aid website. This site includes detailed information about RAI, short videos, drop-down menus with extra details, exercises to help clarify values, and tools to help patients prepare questions for their doctor. The other group will receive the American Cancer Society (ACS) website. This site gives basic information about RAI but does not include interactive tools and is not specific to intermediate-risk thyroid cancer. Follow up surveys will be sent to the participants periodically, first at the start of the study, and again at 1 week, 4 weeks, and 6 months later. Researchers will compare how the two groups differ in making informed decisions. The decision aid is meant to support, not replace, a conversation with the medical team. Doctor recommendations remain an important part of treatment decisions.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Patients aged 18 and older * Patients diagnosed with intermediate risk DTC \< 6 months ago and who are making a decision about RAI treatment * Ability to understand the information conveyed in the informed consent form, pose questions and process answers (e.g., no cognitive impairment per direct consultation with the patient's physician), and, finally, provided informed consent to participate. * Participants willingness to be contacted and remain available to complete study activities throughout the duration of the study. Exclusion Criteria: * Diagnosis of low risk or high risk DTC * Prior history of RAI * Clinical contraindications that prevent consideration of RAI (e.g., pregnancy, lactation, neutropenia if considering high dose of RAI)

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
