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 This study
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 Results may not be published yet.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.

Summary

This study tests whether checking sentinel lymph nodes during breast cancer surgery (using a rapid freezing method) helps surgeons decide right away if more lymph nodes need to be removed, compared to the usual method of waiting for final results after surgery. About 142 women with breast cancer who haven't had prior treatment will take part. The goal is to see if the faster method improves surgical planning and reduces the need for additional procedures.

What this could mean

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

Active substance
Intraoperative frozen section examination of sentinel lymph nodes
What this could lead to
If successful, this approach could help surgeons make better decisions during breast cancer surgery, potentially reducing the need for a second operation.
What could go wrong
This is a small, single-center study with 142 participants. The frozen section technique may not always be accurate, and results may not apply to all breast cancer patients.
