Cardiac Conduction Disorders in Melanoma Patients Treated with CTLA-4-Containing Versus PD-1-Only Immune Checkpoint Inhibitor Therapy: A Propensity Score-Matched Real-World Analysis
Background: Immune checkpoint inhibitors (ICIs) have transformed the treatment of advanced melanoma, but the comparative cardiac safety of cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4)-containing regimens versus programmed cell death protein 1 (PD-1)-only regimens in real-world populations remains poorly characterized. We compared cardiac outcomes between melanoma patients exposed to CTLA-4 blockade (ipilimumab) and those treated with anti-PD-1 therapy alone (nivolumab or pembrolizumab) using a large multice …
