Cardiac Dose Reduction with Deep-Inspiratory Breath Hold Technique of Radiotherapy for Left-Sided Breast Cancer
INTRODUCTION Different techniques of radiation therapy have been studied to reduce the cardiac dose in left breast cancer. AIM In this prospective dosimetric study, the doses to heart as well as other organs at risk (OAR) were compared between free-breathing (FB) and deep inspiratory breath hold (DIBH) techniques in intensity modulated radiotherapy (IMRT) and opposed-tangent three-dimensional...
متن کاملA Comparative Study of 3-D Conformal Radiotherapy Treatment Plans with and Without Deep Inspiration Breath-Hold Technique for Left-Sided Breast Cancer
Introduction: The rate of cardiac diseases have increased among patients who underwent radiotherapy for left-sided breast cancer. The study’s aim was evaluate the dose to organs at risk in free-breathing 3-dimensional conformal (FB-3DCRT) against 3-dimensional conformal deep inspiration breath-hold (3DCRT-DIBH) in patients with left-sided breast cancer. Ma...
متن کاملDosimetric effect due to the motion during deep inspiration breath hold for left‐sided breast cancer radiotherapy
Deep inspiration breath-hold (DIBH) radiotherapy for left-sided breast cancer can reduce cardiac exposure and internal motion. We modified our in-house treatment planning system (TPS) to retrospectively analyze breath-hold motion log files to calculate the dosimetric effect of the motion during breath hold. Thirty left-sided supine DIBH breast patients treated using AlignRT were studied. Breath...
متن کاملThe Role of Active Breathing Control-Moderate Deep Inspiration Breath-Hold (ABC-mDIBH) Usage in non-Mastectomized Left-sided Breast Cancer Radiotherapy: A Dosimetric Evaluation
The aim of this study is to evaluate the dosimetric impact of utilizing Active Breathing Control-moderate deep inspiration breath-hold (ABC-mDIBH) technique in early-stage left-sided breast cancer radiotherapy (RT). Twenty-five patients with left-sided early-stage breast cancer undergoing breast-conserving surgery referred to our department for adjuvant radiotherapy between October 2010 and Oct...
متن کاملThe deep inspiration breath hold technique using Abches reduces cardiac dose in patients undergoing left-sided breast irradiation
PURPOSE We explored whether the deep inspiration breath hold (DIBH) technique using Abches during left-sided breast irradiation was effective for minimizing the amount of radiation to the heart and lung compared to free breathing (FB). MATERIALS AND METHODS Between February and July 2012, a total of 25 patients with left-sided breast cancer underwent two computed tomography scans each with th...
