Dosimetry of the left anterior descending coronary artery in left breast cancer patients treated with postoperative external radiotherapy

AimTo evaluate the dose distribution to the left anterior descending (LAD) coronary artery in patients treated with postoperative three-dimensional conformal radiotherapy (3DCRT).BackgroundPostoperative radiotherapy may increase the risk of heart disease, particularly in patients with left-sided breast cancer. Clinical data on doses to the LAD are limited.Materials and methodsRetrospective study of 14 patients who underwent postoperative 3DCRT for left breast cancer in 2014. All data were retrieved from medical records. Means, medians, ranges, and percentages were calculated.ResultsThe mean dose to the LAD in patients with V25[[ce:hsp sp="0.25"/]
