What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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

Summary

This study looks at using radiofrequency ablation (RFA) — a procedure that uses heat to destroy cancer cells — for small papillary thyroid cancers. Researchers will follow 50 adults who chose RFA over surgery to see how well it works and how safe it is. The goal is to offer a less invasive option with fewer side effects than traditional thyroid surgery.

What this could mean

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

Active substance
radiofrequency ablation
What this could lead to
If successful, this could offer a non-surgical option for small thyroid cancers, reducing risks like voice changes and scarring.
What could go wrong
This is a small observational study, not a randomized trial. Results may not apply to everyone, and risks like nerve injury or bleeding remain.
