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 Results may not be published yet.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 compares two methods for marking non-palpable breast tumors before surgery: magnetic clips and traditional metal wires. Researchers will track costs, how well the marker finds the tumor, and patient satisfaction in 772 women across France. The goal is to see if magnetic clips offer a better or cheaper option for breast-conserving surgery.

What this could mean

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

Active substance
magnetic clip localization
What this could lead to
If magnetic clips prove cheaper or better, they could replace wires for marking tumors before breast surgery, improving patient experience and reducing costs.
What could go wrong
This is an observational study, not a randomized trial, so results may be biased. It only looks at costs and short-term outcomes, not long-term cancer control.
