The aim of this study was to determine the risk factors for immune-related adverse events (irAEs) induced by immune checkpoint inhibitors. The authors conducted a retrospective study in which patients with malignant melanoma, non-small-cell lung cancer, gastric cancer or renal cell carcinoma who received anti-PD-1/PD-L1 antibodies were included. Of 247 patients, 118 developed a total of 182 irAEs. In the multivariate Fine–Gray regression analysis, serum albumin level ≥3.6 g/dl (hazard ratio: 1.62; 95% CI: 1.10–2.39; p = 0.015) and history of Type I hypersensitivity reactions (hazard ratio: 1.48; 95% CI: 1.02–2.14; p = 0.037) were significantly associated with the development of irAEs. High serum albumin levels and history of Type I hypersensitivity reactions are risk factors for irAEs.
