Cardiovascular Risk Profile of Chimeric Antigen Receptor T-cell Therapy

Chimeric antigen receptor (CAR) T-cell therapy is a novel form of immunotherapy that has been recently introduced in clinical practice for the treatment of leukemias and lymphomas after being approved by United States Food and Drug Administration (USFDA). The risk profile of this treatment modality is not yet fully explored. As the survival of cancer patients is expected to rise due to new therapies being brought into practice, physicians are going to encounter side effects of these therapies. This may include both short-term and long-term effects. Having a good knowledge of these side effects can help the physicians recognize in advance the at-risk population and risk stratify them accordingly. Cardiac oncology is a growing field that involves the study of interaction between novel immunotherapies and their cardiac side effects. Knowing the cardiotoxicity profile of CAR T-cell therapy will help us choose the most appropriate patient population (those who can benefit the most without being at risk of harmful effects including cardiotoxicity) for the therapy. It will also help us recognize various cardiac complications, as they arise later during the lifetime of these cancer survivors.
