Cancer survivors: An expanding population with an increased cardiometabolic risk

Abstract

In the last decades the survival rate of patients diagnosed with cancer - both in childhood and adulthood - significantly improved, leading to a growing number of cancer survivors (CS) within general population. Despite the better survival rate related to the cancer diagnosis, CS show increased mortality and morbidity if compared to non-cancer population, due to the occurrence of health conditions categorized as late effects of previous anticancer treatments. Cardiovascular (CV) diseases are one of the main responsible for this increased morbidity of CS. Besides the direct injury that both chemotherapy and radiotherapy can produce to CV system, in recent years the role of metabolic syndrome in the pathogenesis of CV diseases in CS is emerging. The relationship between anticancer treatments and the development of metabolic alterations is crucial to understand and manage the cardiometabolic risk in CS. The aim of this manuscript is to review the pathophysiological and clinical features of CV risk factors in CS, exploring in more detail certain subgroups of CS (breast cancer, transplanted patients as well as lymphoma survivors) that show peculiar clinical aspects and are burdened by a greater CV risk.
