KIM-1 is a marker of nephrotoxicity in patients receiving cisplatin-containing chemotherapy

Drug-induced nephrotoxicity is a common side effect in chemotherapy treatment for cancer patients. Every year the relevance of this problem increases due to the widespread use of various chemotherapy (CT) protocols, including nephrotoxic drugs, in particular cisplatin. Standard measures of kidney function include glomerular filtration rate (GFR), serum creatinine (sCr) and blood urea nitrogen concentrations. However, their changes are revealed after a rather long period after nephrotoxic exposure only; in addition, they deviate significantly from the norm only with a significant degree of kidney damage. Therefore, the search for new markers of nephrotoxicity for early and reliable diagnostics of renal dysfunction is an extremely urgent task. One such promising marker is KIM-1.
