Immune checkpoint inhibitors (ICI), immunomodulatory antibodies that are used to enhance the immune system, have substantially improved the prognosis of patients with advanced malignancy. As use of ICI therapy becomes increasingly widespread across different types of cancer, their use in patients receiving dialysis is likely to increase. In this review, we summarize the current literature on use of ICI in ESKD patients and provide aggregate data from reported cases and series. Based on available pharmacological information, ICIs require no dosing adjustment in ESKD patients. Analysis of the reported cases in the literature demonstrates similar incidence of immune-related adverse events in patients with ESKD receiving dialysis as compared to the general population (49%). Severe reactions graded as 3 and 4 have been seen in fifteen patients (16%). As such, it is important that these patients are monitored very closely for irAE, however the risk of these adverse events should not preclude patients on dialysis from receiving these therapies. Cancer remission (complete and partial) was seen in close to 30% of patients. Stable disease was seen in 28% and progression of disease in approximately 36% of patients. One-third of the patients died. Urothelial and renal cell cancer represented approximately half of all treated cancers, and accounted for approximately 50% of all deaths reported. Additional data in the dialysis population with use of ICI, and involvement in prospective studies, is needed to better assess outcomes, particularly within specific cancer types.
