Thomas Jefferson University researchers have developed a prospective trial to assess if radiation therapy with the Active Breathing Coordinator (ABC) could reduce mean heart dose (MHD) and lung incidental radiation in breast cancer patients. Breast cancer patients undergoing radiation therapy are often exposed to incidental radiation dose to the heart and lung, which can increase the risk for ischemic heart disease (IHD) and lung cancer, especially in women suffering from left-sided breast cancer. Over the last few years, several techniques have been developed that can minimize radiation exposure to organs considered at risk. One such technique is moderate deep inspiration breath hold (mDIBH) with the Active Breathing Coordinator (ABC) device (Elekta Oncology). The ABC guarantees immobilization of the chest wall through monitorization of a patient’s breathing cycle and can implement a breath hold at a predefined lung volume. This device can optimize the distance between the heart and chest wall, moving the organs at risk out of the radiation field but still permitting correct irradiation of the breast tissue.
