Radiation Dose Linked To Cardiac Risk In Breast Cancer Patients



In the past, cardiovascular risk has been linked to the radiation dose received by breast cancer patients. Now, a new study published in JAMA Internal Medicine attempts to calculate the cardiac risk of breast cancer patients today undergoing current radiotherapy protocols.


David J. Brenner and colleagues calculated the excess cardiac risk for 48 patients who received radiotherapy at New York University. They estimated the 20-year cardiac risk based on baseline risk and patient-specific mean cardiac radiation dose. Cardiac dose was significantly higher in patients with left-sided radiotherapy. These patients also received significantly higher doses if they were treated in the supine body position instead of the prone position. Position did not significantly have an impact on cardiac dose in patients who received right-side radiotherapy.
