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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 is testing whether a CT-free electromagnetic navigation system can accurately locate small lung nodules before surgery, compared to the standard CT-guided method. The goal is to see if the new approach can mark nodules within 10 millimeters of their center, which is crucial for successful removal. Researchers will also compare procedure time, complications, and recovery. The study involves adults with non-palpable pulmonary nodules who need sublobar resection.

What this could mean

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

Active substance
CT-Free electromagnetic navigation percutaneous localization system
What this could lead to
If successful, this could offer a safer, faster, and more accurate way to mark lung nodules before surgery, potentially reducing the need for repeated CT scans and improving surgical outcomes.
What could go wrong
This is an observational study, so it cannot prove cause and effect. The new method may not be as accurate or safe as standard CT-guided localization, and results may vary across different centers.
