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 Results may not be published yet.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

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 compares a newer, less invasive mastectomy technique (endoscopic skin-sparing) with the standard approach in 258 women with breast cancer. The goal is to see if the endoscopic method leads to fewer wound complications and higher patient satisfaction. Participants are randomly assigned to one of the two surgeries, and their recovery and cosmetic outcomes are tracked.

What this could mean

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

Active substance
Endoscopic skin-sparing mastectomy (a less invasive surgical procedure)
What this could lead to
If successful, this could show that endoscopic mastectomy reduces wound problems and improves cosmetic results for certain breast cancer patients.
What could go wrong
This is a relatively small, early-stage trial (258 participants) comparing surgical techniques, so results may not apply to all patients. The endoscopic approach may not be suitable for everyone and could have unknown risks.
