Clinical Diagnosis and Treatment Recommendations for Cardiac Adverse Reactions Related to Immune Checkpoint Inhibitor / 中国肺癌杂志

ABSTRACT

Immunotherapy of malignant tumors has become a hot spot in the field of cancer research and treatment, bringing new hope to patients with advanced cancer. Activation of molecular programmer death protein-1 and T lymphocyte-associated antigen 4-related signaling pathways at the immunological checkpoint can inhibit T lymphocyte activation and thereby block the inflammatory response. Tumor cells achieve immune escape by activating the molecular pathways associated with immune checkpoints. The immune checkpoint inhibitor can wake up T lymphocytes and enhance the body's clearance of tumor cells. However, the role of immune checkpoint inhibitors is not specific to tumor cells, and it can cause side effects of multiple systems including the cardiovascular system while killing tumor cells. We will summarize the relevant cardiac side effects and give advice on how to manage it.
