Episode Details

Immunotherapy is a type of novel cancer therapy that leverages the body’s own immune system to target cancer cells. In this episode, we focused on the most common type of immunotherapy: immune checkpoint inhibitors or ICIs. ICIs are monoclonal antibodies targeting immune “checkpoints” or brakes to enhance T-cell recognition against tumors. ICI has become a pillar in cancer care, with over 100 approvals and 5,000 ongoing trials. ICIs can lead to non-specific activation of the immune system, causing off-target adverse events such as cardiotoxicities. ICI-related myocarditis, though less common, can be fatal in 30% of cases. Clinical manifestations vary but can include chest pain, dyspnea, palpitations, heart failure symptoms, and arrhythmias. Diagnosis involves echocardiography, cardiac MRI, and endomyocardial biopsy. Treatment includes high-dose corticosteroids with potential additional immunosuppressants. Baseline EKG and troponin are recommended before ICI initiation, but routine surveillance is not advised. Subclinical myocarditis is a challenge, with unclear management implications. So let’s dive in and learn about cardiotoxicity of novel immunotherapies with Drs. Giselle Suero (series co-chair), Evelyn Song (episode FIT lead), Daniel Ambinder (CardioNerds co-founder), and Tomas Neilan (faculty expert). Audio editing by CardioNerds Academy Intern, Dr. Maryam Barkhordarian.
