Association Between Sinoatrial Node Radiation Dose and New-Onset ECG Abnormalities After Breast Cancer Intensity-Modulated Radiotherapy.

PURPOSE To investigate the association between cardiac conduction system dosimetry, specifically the sinoatrial node (SAN), for new-onset electrocardiogram (ECG) abnormalities in breast cancer (BC) patients undergoing intensity-modulated radiotherapy (IMRT). METHODS We retrospectively reviewed 91 BC patients treated...

Beyond mean heart dose: differentiated electrocardiographic manifestations and dosimetric mechanisms of cardiac injury in left-sided versus right-sided breast cancer after intensity-modulated radiotherapy

Objective To investigate dosimetric exposure variations to the whole heart and substructures between left- and right-sided breast cancer patients receiving intensity-modulated radiotherapy (IMRT), and to evaluate their relationships with post-radiotherapy (post-RT) electrocardiogram (ECG) alterations. Methods Clinical...

Beyond mean heart dose: quantitative impact of sub-structure spatial dosimetrics on subclinical myocardial strain in thoracic radiotherapy

Hyper-acute subclinical strain alterations are highly prevalent immediately after thoracic radiotherapy, with right-sided structures exhibiting enhanced radiosensitivity, and independent sparing of the conduction system and coronary vasculature should be considered in precision radiotherapy, warranting validation in fu...
