Minireview. The nephrotoxicity of cisplatin

Cisplatin is a cancer chemotherapeutic agent whose clinical use is complicated by its dose related kidney toxicity. Since the histopathological profile of cisplatin nephrotoxicity appears similar to that of other heavy metals, it has been commonly presumed that cisplatin nephrotoxicity is related to the platinum moiety. However, the delayed time course and development of cisplatin nephrotoxicity is not characteristic of heavy metal nephropathy. Furthermore, cisplatin nephrotoxicity is stereospecific to the cis and not the trans isomer, indicating that the platinum atom is not the proximate nephrotoxicant. It is likely that a metabolite of cisplatin, possibly an aquated and/or hydroxylated complex, mediates the nephrotoxicity of cisplatin.
