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 Results may not be published yet.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

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This status has not been confirmed recently, so it may be out of date.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 tests a special dye that makes cancer cells glow when applied to lymph nodes removed during breast cancer surgery. The goal is to help surgeons instantly tell if a sentinel lymph node contains cancer, so they only remove the nodes that are truly affected. The trial will enroll 60 adults with breast cancer and compare the dye's results with standard lab tests.

What this could mean

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

Active substance
NIR-II fluorescent probe (ICG-CK)
What this could lead to
If successful, this could give surgeons a real-time tool to tell cancerous from healthy lymph nodes during surgery, potentially reducing side effects like arm swelling.
What could go wrong
This is an early-stage, small trial (60 people) testing a new imaging method. The dye may not reliably distinguish all cancer types, and false positives or negatives are possible.

Who can take part

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

Who is studied

The investigators plan to enroll 90 female patients, aged 18 to 75 years, who have been assessed to have resectable breast nodules or masses and are scheduled to undergo surgery. During the surgery, the resected lymph nodes will be incubated with theNIR-II probe(ICG-CK) solution, and NIR-II fluorescence signals from the tissues will be collected.
