Cardiotoxicity in breast cancer patients after radiotherapy – modern methods of minimizing the dose to the heart and dilemmas of choosing critical cardiac structures for monitoring dose distribution
Languages of publication
Radiotherapy in breast cancer patients is an important component of multidisciplinary treatment. It reduces the risk of local recurrence and mortality from breast cancer. However, it can lead to secondary effects due to the presence of the heart within the irradiation field. Adjuvant radiation therapy for breast cancer increases the risk of coronary artery disease, myocardial infarction and cardiovascular death. It is important to determine the optimal treatment to minimize cardiotoxicity. Modern radiotherapy techniques may reduce radiation-induced cardiac toxicity, but it is necessary to determine the most sensitive structures within the heart, tolerance doses, and methods for early detection and monitoring of adverse effects.
