Although it is important to develop strategies for the early detection of severe irAEs, there is a lack of evidence on irAEs associated with ipilimumab plus nivolumab therapy for metastatic renal cell carcinoma (RCC). Therefore, this study aimed to investigate the association between eosinophil and severe irAEs in patients receiving ipilimumab plus nivolumab therapy for RCC.MethodsIn this retrospective study, 161 patients receiving ipilimumab plus nivolumab therapy for RCC were divided into three groups based on whether they experienced
