Anti-cancer agents and endothelium

Recent advances in oncology have improved the treatment outcomes and life expectancy of cancer patients; therefore, late effects of oncological treatment are of high clinical importance. Recent studies have shown that cardiovascular events are among the leading causes of premature morbidity in cancer survivors. Cardiotoxicity of some chemotherapeutic agents have been already confirmed; however, this issue seems to be more complex. Endothelium dysfunction is one of the first recognisable signs of atherosclerosis, which occurs long before the development of overt cardiovascular disease. Thus, it could be considered as an initial step, leading to increased risk of cardiovascular events. This process is not easy to recognise; however, there are some laboratory tests and imagining techniques that provide an insight into the progression of endothelial dysfunction. In this review we discuss the influence of oncological treatment on endothelium, according to the hypothesis that it increases cardiovascular morbidity and mortality in cancer survivors. Additionally, we present diagnostic and therapeutic measures that could reduce cardiovascular risk in cancer patients.
