Immune checkpoint inhibitor myocarditis in thymic epithelial tumors: a case report and literature review

Background: Immunotherapy offers new hope for cancer patients but presents new medical challenges for healthcare workers in terms of the management of immune-related adverse events (irAEs). The clinical data of two patients with advanced thymoma (T) admitted to the Fujian Cancer Hospital who developed fulminant myocarditis after undergoing immunosuppressant therapy were analyzed retrospectively, and the relevant literature was reviewed. This study aims to examine treatment of thymic epithelial tumors (TETs)-associated immune myocarditis.
