Complications cardiaques de la radiothérapie mammaire

Abstract : Adjuvant radiation therapy in breast cancer is a standard of care, either post-lumpectomy or in case of lymph node involvement. Internal mammary chain (IMC) is more and more included in the clinical target volume, because it increases overall survival. This increase must be weighed against cardiac complications in left breast cancer. Intensity modulated radiation therapy (IMRT) is used in this indication in order to better cover target volumes, but tends to increase irradiated healthy volumes, including the heart. The average cardiac dose is higher with IMRT, while it is also predictive of cardiovascular events in patients treated in 3D. This article aims to make an inventory of the IMC irradiations, as well as a review of the mechanisms of radiation-induced cardiac toxicity and ways to diagnose it early. Cooperation between medical oncologists, radiotherapy oncologists and cardiologists is needed to better support patients.
