[Radiotherapy and atherosclerosis: current data and issues].
The continuous optimization of cancer treatment with radiotherapy raises the problem of long-term issue of patients treated and cured by ionizing radiation, with the possible occurrence of second cancers or nonmalignant complications. Among these, cardiovascular diseases are prevalent and may affect up to 40 % of patients depending on the location of the irradiation. Recent epidemiological studies show that this problem is underestimated and with no real prospective studies. The management of these patients with vascular risk, or with very high vascular risk for those with pre-existing traditional cardiovascular risk factors, remains to be determined. The pathophysiological mechanisms of radiation-induced atherosclerosis have not yet been clarified. Many efforts are still needed to identify patients at risk and to find or to propose an appropriate treatment. Prolonged vascular follow-up of patients after their radiotherapy should now be integrated into patterns of care, especially because the setting up of sophisticated technical platforms of radiotherapy do not necessarily solve the issue of cardiovascular risk after treatment. double dagger.
