TY - JOUR T1 - POsitioning during radiotherapy for breast cancer AU - Sherr DL Y1 - 2013/01/09 N1 - 10.1001/jama.2012.56914 JO - JAMA SP - 137 EP - 137 VL - 309 IS - 2 N2 - To the Editor: Dr Formenti and colleagues1 demonstrated that prone positioning (vs supine positioning) significantly decreased the volume of heart and lung tissue exposed to radiation in women being treated for breast cancer. However, an important component of radiation-induced cardiac toxicity, in addition to the volume of irradiated myocardium, is the extent of coronary artery irradiation.2- 4 SN - 0098-7484 M3 - doi: 10.1001/jama.2012.56914 UR - http://dx.doi.org/10.1001/jama.2012.56914 ER -
