免疫治疗相关心脏毒性：精准心脏肿瘤学的当前见解与未来方向

Background/Objectives : Cancer immunotherapy has revolutionized the field of oncology by harnessing the immune system to attack cancer cells, increasing survival in a broad spectrum of malignancies.

However, despite its positive therapeutic benefit, immunotherapy is also associated with a spectrum of adverse events affecting various vital organs, including the cardiovascular system. Methods : We conducted a comprehensive review of the available literature on the epidemiology, pathophysiological mechanisms, and current management approaches for cardiovascular adverse events associated with cancer immunotherapy.

In addition, we evaluated emerging personalized strategies and interventions aimed at mitigating these risks and improving patient outcomes. Results : Immunotherapy is associated with a broad spectrum of potentially serious cardiovascular adverse events, including immune-mediated myocarditis, heart failure, arrhythmias, pericarditis, and accelerated atherosclerosis. Among these, immune checkpoint inhibitor-associated myocarditis is the most well characterized and potentially fatal form of cardiotoxicity, with reported mortality rates approaching 50%. Similarly, chimeric antigen receptor T-cell therapy, despite its powerful antitumor efficacy, is frequently associated with cytokine release syndrome-a profound immune activation that can lead to significant systemic and cardiovascular complications.

In response to these challenges, several personalized strategies are currently under development, including artificial intelligence and machine learning approaches, genetic and transcriptomic profiling, novel biomarker discovery, and integrated risk scoring systems, all aimed at enhancing risk stratification and improving patient care. Conclusions : Cancer immunotherapy has been associated with a range of immune-related cardiac adverse events, both non-severe and severe.

As such, it is critically important to adopt a personalized approach to patient management before, during, and after the administration of immunotherapy. Early recognition through heightened clinical vigilance, along with the implementation of individualized risk assessment tools, is essential for identifying patients at high risk of immunotherapy-induced cardiotoxicity. These strategies are imperative for optimizing patient outcomes and ensuring safe and effective cancer treatment.
