In addition, many patients may receive chemotherapy prior to radiation which may damage the myocardium and may increase the potential for late cardiac complications. New radiotherapy techniques such as intensity-modulated radiotherapy (IMRT) may decrease the risk of cardiac toxicity because of the steep dose gradient limiting the volume of the heart irradiated to a high dose. Image-guided radiotherapy (IGRT) is a new technique of IMRT delivery with daily imaging which may further reduce excessive cardiac irradiation. Preliminary results of IGRT for cardiac sparing in patients with left-sided breast cancer are promising and need to be investigated in future prospective clinical studies. %K breast cancer %K cardiac toxicity %K left breast %K IGRT %K prevention %U http://www.frontiersin.org/Journal/10.3389/fonc.2014.00257/abstract
