One-Time radiation during surgery could spare older breast cancer patients weeks of treatment

NCT ID NCT04414202

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looks at giving a single dose of radiation directly to the tumor site during breast-conserving surgery in women aged 60 and older with early-stage, hormone-sensitive breast cancer. The goal is to see if this shorter, targeted approach controls the cancer as well as standard weeks-long whole-breast radiation. Researchers are tracking local relapse rates and cosmetic outcomes in 519 participants.

What this could mean

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

Active substance

intra-operative partial irradiation (radiation therapy given during surgery)

What this could lead to

If successful, this could offer a shorter, more convenient radiation option for older women with early-stage breast cancer, reducing treatment time from weeks to a single dose.

What could go wrong

This is an observational study, not a randomized trial, so results may not prove the approach is as effective as standard whole-breast radiation. Long-term local relapse rates are still being tracked.
