No knife needed? new trial tests if chemo and radiation alone can cure breast cancer

NCT ID NCT06498154

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase 2 trial is testing whether women with certain aggressive breast cancers (triple negative or HER2-positive) can safely avoid breast surgery if their tumors disappear completely after a combination of chemotherapy and radiation. The study will enroll 200 women and follow them for 5 years to see if the cancer stays away. If it works, it could spare many patients from surgery and its recovery time.

What this could mean

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

Active substance
chemotherapy (TCb regimen with or without immunotherapy for triple negative; TCb plus trastuzumab and pertuzumab for HER2+) and radiotherapy (whole-breast irradiation plus boost)
What this could lead to
If successful, this could show that some breast cancer patients can avoid surgery entirely after strong chemo and radiation, reducing treatment burden.
What could go wrong
This is a phase 2 trial with only 200 people, so results are preliminary. There is a risk that cancer may return without surgery, and the combination of chemo and radiation may cause more side effects.
