The enhancement of immune responses upon treatment with immune checkpoint inhibitors can have the desired outcome of reinvigorating antitumour immune surveillance, but often at the expense of immune-related adverse events (irAEs). This novel disease entity often prompts comparisons with, and extrapolation of treatment approaches from, primary autoimmune disorders. Accordingly, current treatment guidelines for irAEs make generic recommendations adapted from the literature describing primary autoimmune diseases, without taking into consideration the substantial disparity of the immunohistopathological findings within each organ affected by an irAE. The treatment modalities themselves are complex and have many potential drawbacks, such as serious and rarely fatal infections, drug toxicities overlapping with irAEs and the risk of compromising cancer immune surveillance. Herein, we provide an …
