New study aims to decode cancer risk in treated thyroid nodules

NCT ID NCT05726981

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study follows 180 people who had a benign thyroid nodule treated with radiofrequency heat ablation three years ago. Researchers will use ultrasound and a fine-needle biopsy to see how the nodule looks and whether any cells have changed. The goal is to create a better way to spot cancer in these treated nodules, since current ultrasound rules don't apply well after ablation.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
radiofrequency thermal ablation
What this could lead to
If successful, this could create a new ultrasound-based system to better predict cancer risk in treated thyroid nodules, reducing unnecessary biopsies.
What could go wrong
This is an early exploratory study with no control group, so results may not apply to all patients. The findings are descriptive and may not change current practice.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

85 people

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Patients \> 18 years old 2. Carrier of a benign thyroid nodule that has undergone radiofrequency thermoablation 36 months previously ± 12 months +/- 1 month, whether the nodule is stable, progressing or decreasing in volume during the screening period and/or on the day of inclusion. 3. Obtaining written informed consent 4. Affiliation to a social security system (excluding AME) Exclusion Criteria: 1. Pregnant or breastfeeding women 2. Previous alcohol use 3. Patients on anti-vitamin K anticoagulants 4. Patients on direct oral anticoagulants 5. Persons deprived of liberty by judicial or administrative decision 6. Persons under forced psychiatric care 7. Persons admitted to a health or social institution for purposes other than research 8. Persons of full age who are under legal protection (guardianship or curatorship) 9. Persons unable to express their consent 10. Persons under a legal protection measure (there can be no derogation for this category)
