Purpose/Objective:
Deep Inspiration Breath Hold (DIBH) is a well-established technique used to minimize radiation exposure to the heart and left anterior descending coronary artery (LAD) during treatment for left breast cancer [1].
When considering treatment for right breast cancer (R-BC), limited studies with small patient cohorts have demonstrated dosimetric advantages of DIBH in case of Regional Nodal Irradiation (RNI) [2] and hepatomegaly [3] for lung sparing. Thus, there is still a paucity of data regarding the application of DIBH in right breast cancer radiation therapy, leaving uncertainty about which patients stand to gain the most from this approach.
This study aims to evaluate the dosimetric benefits of DIBH in the locoregional irradiation of right breast cancer (R BC) using modulated radiotherapy, in comparison to Free Breathing (FB).
