Immune-related adverse events (irAEs) should be anticipated with treatment by immune checkpoint inhibitors (ICIs). Although the relationship between irAEs and efficacy of ICI has been reported, it has not yet been clarified whether the benefit from ICI outweighs the low frequency of proceeding to subsequent therapies after discontinuation due to irAEs. ⋯ Discontinuation of treatment with ICIs due to irAEs predict a good response to ICIs and favorable outcome since their anti-cancer effects continue even after discontinuation. However, the presence of IP as the underlying disease increases the risk of drug-related ILD onset.
