BRAVE-HEART: Breast Cancer Radiotherapy Using Active Breathing Coordinator to aVoid Exposure of HEART
The BRAVE-HEART trial is an ambispective, observational, non-randomized study conducted at Fondazione IRCCS (Istituto di Ricovero e Cura a Carattere Scientifico) Policlinico San Matteo (Pavia, Italy). It aims to document and quantify the cardiac dose reduction achievable with breast radiotherapy performed in Deep Inspiration Breath Hold (DIBH) using the Active Breathing Coordinator (ABC) system. Dosimetric parameters from DIBH treatments are evaluated, with free-breathing treatment plans and data from patients treated under free-breathing conditions used as reference. Secondary analyses include treatment reproducibility, comparison of radiotherapy techniques and fractionation schedules, impact of the simultaneous integrated boost (SIB), and assessment of acute and late toxicity during follow-up.
• 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
• Ability to actively cooperate in using the Active Breathing Coordinator (ABC) system for Deep Inspiration Breath Hold (DIBH), or treated under free-breathing conditions when DIBH is not feasible
• Age ≥18 years
