Key result
Modern cardiac sparing radiotherapy techniques, including deep inspiration breath hold and advanced delivery methods, play a pivotal role in reducing the risk of radiation-induced cardiotoxicity in breast cancer survivors.
Why the study?
Unintended cardiac irradiation during breast cancer radiotherapy can cause cardiotoxicity, and further evidence is needed on patient selection, predictors, biomarkers, and heart substructure dose constraints.
Do modern cardiac-sparing radiotherapy techniques reduce radiation dose to the heart and subsequent cardiac toxicity in breast cancer patients?
Do modern cardiac-sparing radiotherapy techniques reduce radiation dose to the heart and subsequent cardiac toxicity in breast cancer patients?
Modern cardiac-sparing radiotherapy techniques are crucial for reducing the non-negligible burden of radiation-induced cardiotoxicity in long-term breast cancer survivors.
Optimal patient selection for cardiac-sparing RT in BC remains unclear; leaves open refined criteria to minimize cardiotoxicity.
Radiotherapy (RT) is a mainstay of Breast Cancer (BC) patients therapy. Nonetheless, unintended irradiation of the heart and its substructures can result in cardiac toxicity, jeopardizing long-term survivors’ quality of life (QOL). Advances in RT delivery techniques deeply impacted this clinical scenario. Indeed, given the non-negligible burden of cardiotoxicity, modern cardiac sparing approaches have a pivotal role. Nonetheless, further evidence is eagerly awaited regarding patients’ selection, clinical predictors, biological markers, and particularly heart substructures dose-constraints.
