Robots take on breast cancer surgery: a new trial tests safety and survival
NCT ID NCT05490433
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares robot-assisted nipple-sparing mastectomy (RNSM) to conventional open surgery in women with early-stage breast cancer (stage 0 to IIIA) who want immediate breast reconstruction. About 790 participants will be randomly assigned to one of the two procedures. The main goal is to see if the robot-assisted approach is as good as open surgery in preventing cancer from coming back over five years.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
robot-assisted nipple-sparing mastectomy (RNSM)
What this could lead to
If successful, this could show that robot-assisted mastectomy is as safe and effective as open surgery, offering a less invasive option with similar cancer control.
What could go wrong
This is a non-inferiority trial, meaning it aims to prove the robot method is not worse than open surgery. It may not show clear benefits, and long-term outcomes are still being studied.
