Large Segmentation Radiotherapy±Deep Inspiratory Breath Hold for Left Sided Breast Cancer, A Real-World Study
The study is a single-center, prospective, non-randomized controlled study. The primary objective is to examine the clinical outcomes of utilizing Deep Inspiration Breath Hold (DIBH) in conjunction with hypo-fractionated radiotherapy for patients diagnosed with left-sided breast cancer with a particular focus on its potential to reduce the incidence of cardiac-related clinical and subclinical events.Participants will revieve large segmentation sadiotherapy ± DIBH for left breast cancer and be followed up to gather their clinical cardiac imformation.
