Breast radiotherapy using active breath hold to reduce heart exposure

Official title: BRAVE-HEART: Breast Cancer Radiotherapy Using Active Breathing Coordinator to aVoid Exposure of HEART

Run by Fondazione IRCCS Policlinico San Matteo di Pavia · NCT07299812 · Data updated 2026-11-12

This project will see if using an Active Breathing Coordinator (ABC) for deep inspiration breath hold reduces radiation dose to the heart in adults with stage I–III breast cancer receiving radiotherapy.

Is this trial a fit for you?

Likely a good fit

Adults (≥18 years) with stage I–III breast cancer who are scheduled for postoperative or definitive radiotherapy and who can cooperate with ABC‑assisted DIBH (or are treated under free‑breathing if DIBH is not feasible) are ideal candidates.

Probably not a fit

Patients with severe respiratory or cardiovascular disease who cannot perform or maintain breath‑hold maneuvers, pregnant patients, or those with absolute contraindications to radiotherapy are unlikely to benefit from ABC‑assisted DIBH.

What this trial studies

BRAVE-HEART is an ambispective, observational single-center study at Fondazione IRCCS Policlinico San Matteo that documents cardiac dose reduction when radiotherapy is delivered with ABC‑assisted deep inspiration breath hold (DIBH). Dosimetric parameters from patients treated with DIBH are compared against free‑breathing plans and historical free‑breathing patients to quantify reductions to the heart and substructures such as the left anterior descending artery. The study enrolls adults with stage I–III breast carcinoma treated with 3D‑CRT or IMRT/VMAT using conventional, hypofractionated, or ultrahypofractionated schedules, with or without a simultaneous integrated boost. Secondary analyses examine treatment reproducibility, differences between techniques and fractionation, the impact of SIB, and acute and late toxicity during follow-up.

Why it matters

Potential benefit: If successful, the approach could lower radiation exposure to the heart and coronary arteries and reduce long-term cardiac complications after breast radiotherapy.

How similar studies have gone: Multiple prior studies have shown that DIBH techniques can reduce cardiac dose in left‑sided breast radiotherapy, so the approach is supported by existing evidence.

Inclusion Criteria:

* Diagnosis of stage I-III breast carcinoma with an indication for radiotherapy
* Invasive carcinoma or ductal carcinoma in situ (DCIS)
* Radiotherapy delivered using three-dimensional conformal radiotherapy (3D-CRT) or intensity-modulated/volumetric modulated arc therapy (IMRT/VMAT) techniques
