          Abstract

          Purpose of Review

          Immune checkpoint inhibitors, such as monoclonal antibodies targeting CTLA-4, PD-1, and PD-L1, have improved the outcome of many malignancies, but serious immune-related cardiovascular adverse events have been observed. Patients’ risk factors for these toxicities are currently being investigated.

          Recent Findings

          Interfering with the CTLA-4 and PD-1 axes can bring to several immune-related adverse events, including cardiotoxic events such as autoimmune myocarditis, pericarditis, and vasculitis, suggesting that these molecules play an important role in preventing autoimmunity.

          Summary

          Risk factors (such as pre-existing cardiovascular conditions, previous and concomitant cardiotoxic treatments, underlying autoimmune diseases, tumor-related factors, simultaneous immune-related toxic effects, and genetic factors) should be always recognized for the correct management of these toxicities.

          Cancer immunotherapy using checkpoint blockade

          The release of negative regulators of immune activation (immune checkpoints) that limit antitumor responses has resulted in unprecedented rates of long-lasting tumor responses in patients with a variety of cancers. This can be achieved by antibodies blocking the cytotoxic T lymphocyte antigen-4 (CTLA-4) or the programmed death-1 (PD-1) pathway, either alone or in combination. The main premise for inducing an immune response is the pre-existence of antitumor T cells that were limited by specific immune checkpoints. Most patients who have tumor responses maintain long lasting disease control, yet one third of patients relapse. Mechanisms of acquired resistance are currently poorly understood, but evidence points to alterations that converge on the antigen presentation and interferon gamma signaling pathways. New generation combinatorial therapies may overcome resistance mechanisms to immune checkpoint therapy.
