HERO trial: skipping radiation after surgery for Low-Risk breast cancer?

NCT ID NCT05705401

Ongoing Disease control Sponsor: NRG Oncology Source: ClinicalTrials.gov ↗

First seen May 02, 2026 · Last updated May 02, 2026

Summary

This study looks at whether women (and men) age 40+ with early-stage, low-risk HER2+ breast cancer can safely skip radiation after breast-conserving surgery if they have already received chemotherapy and HER2-targeted therapy. About 1,300 participants will be randomly assigned to receive or not receive standard radiation. The main goal is to see if the cancer comes back at the same rate in both groups.
