To the Editor With great interest, we read the article by Eggermont et al1 investigating the association between immune-related adverse events (irAEs) and recurrence-free survival (RFS) in patients with melanoma undergoing adjuvant treatment with pembrolizumab in the EORTC 1325/KEYNOTE-054 study. The authors convincingly showed that the occurrence of irAEs was associated with increased RFS. Strikingly, although mild irAEs, such as vitiligo and endocrine irAEs, were strongly associated with RFS, there was no significant association with severe (grade 3 or greater) irAEs.1
