Abstract

Opinion statement Vascular events have become an important issue in the overall management of cancer patients. They usually result from a combination of (i) direct or indirect toxicity of anticancer treatments, (ii) a higher prevalence of cardiovascular risk factors in cancer patients, and (iii) prolonged exposure to treatments due to an increasing patient survival rate. In addition to conventional chemotherapies and radiotherapy, targeted therapies and immunotherapies have been developed which improve the prognosis of cancer patients but sometimes at the cost of vascular toxicity, which can lead to systemic or pulmonary hypertension and arterial/venous thromboembolic events. Endothelial dysfunction, a procoagulant state and metabolic disorders are the three main pathophysiological patterns leading to cancer treatment-related vascular toxicity. This issue is challenging because serious vascular adverse events can necessitate cancer treatment being put on hold or stopped, which could compromise patient survival. In addition to increasing the risk of thrombotic adverse events, cancer therapies may lead to an increased risk of bleeding, especially in treatments with vascular endothelial growth factor inhibitors. Therefore, we can define vasculo-oncology as a part of the cardio-oncology specialty; its aims are to predict, prevent, screen, and treat vascular toxicity related to cancer treatments. While the level of evidence is low regarding the management of vascular toxicity during cancer therapy, cardiologists and specialists in vascular diseases should closely collaborate with oncologists and hematologists to determine the optimal strategy for each patient.
