Fanconi syndrome developing and worsening during anti-myeloma therapy in multiple myeloma: a case report and literature review

Anti-myeloma therapy may transiently induce or exacerbate FS, especially in patients with pre-existing renal tubular dysfunction, likely due to synergistic tubular toxicity of anti-myeloma agents. Early recognition, frequent electrolyte monitoring and prompt correction, as well as multidisciplinary collaboration, are crucial for optimal management of FS.
