Are patients in haemodialysis good candidates for immunotherapy treatment?

The effectiveness and safety of nivolumab, an anti-programmed cell death protein 1 mAbmonoclonal antibody, in patients with renal replacement therapy is unclear, with limited evidence supporting its usefulness in this context. Therefore, we report a case of recurrent metastatic melanoma in a patient on haemodialysis successfully treated with nivolumab. As seen in patients without renal impairment, significant regression of the lesions was observed after 8 weeks of treatment, reaching complete clinical response after 4 months. During follow-up, no dose adjustment, delay, or treatment suspension due to toxicity were required.
