Breast cancer surgery omission trial halted early
NCT ID NCT04578106
First seen Jan 11, 2026 · Last updated Jun 13, 2026 · Updated 18 times
Summary
This study looked at whether women with a certain type of early-stage breast cancer (HER2-positive, low-risk) could avoid surgery if their tumors completely disappeared after standard drug treatment. Only 5 women enrolled before the study was stopped. The goal was to see if a special breast biopsy and MRI could reliably confirm no cancer remained, allowing surgery to be skipped. Because the study ended early, we don't have clear answers on safety or long-term outcomes.
