A systematic review of cardiovascular toxicities induced by cancer immune therapies: Underlying mechanisms, clinical manifestations and therapeutic approaches.

Immunotherapy has revolutionized the management of various types of cancers, even those previously deemed untreatable. Nonetheless, these medications have been associated with inflammation and damage across various organs. These challenges are exemplified by the adverse cardiovascular impacts of cancer immunotherapy, which need comprehensive understanding, clarification, and management integrated into the overall care of cancer patients. Numerous anticancer immunotherapies have been linked to the prevalence and severity of cardiovascular toxicity. These challenges emphasize the importance of conducting fundamental and applied research to elucidate disease causes, discover prognostic indicators, enhance diagnostic methods, and create successful therapies. Despite the acknowledged importance of T cells, there remains a knowledge gap regarding the inciting antigens, the reasons for their recognition, and the mechanisms of how they contribute to cardiac cell injury. In this review, we summarize the molecular mechanism, epidemiology, diagnosis, pathophysiology and corresponding treatment of cardiovascular toxicity induced by immunotherapy, including immune checkpoint inhibitors (ICIs), adoptive cell therapies (ACT), and bi-specific T-cell engagers (BiTEs) among others. By elucidating these aspects, we aim to provide a better understanding of immunotherapies in cancer treatment and offer guidance for their clinical application.
