Background: The use of immunotherapeutic agents, specifically immune checkpoint inhibitors (ICIs) for solid malignancies, is rapidly rising, and many new agents and treatment combinations are in development. However, ICIs have a unique side-effect profile of immune-related adverse events (irAEs) compared with chemotherapeutic agents or targeted therapies.
Methods: In this report the diverse spectrum of irAEs is highlighted using two patients with metastatic melanoma undergoing treatment with ICIs. We supplement these case reports with a brief literature review of the data regarding the safety of surgical intervention in patients taking irAEs.
Results: The report describes the basic approach to the detection and management of irAEs, notes important perioperative considerations, and discusses the safety of surgical intervention for these patients.
Conclusions: Overall, these irAEs represent a diverse group of pathologies with variable timing and sometimes subtle presentation requiring careful monitoring and heightened clinical suspicion for potential toxicity by all providers, including surgeons.
