Cisplatin is a heavy-metal complex widely used in the treatment of a variety of malignancies, including small cell and non-small cell lung cancer, ovarian, bladder, head and neck, esophageal, cervical and germ cell tumors. The administration of cisplatin is commonly associated with certain drug-induced toxicities that may limit their clinical utility and adversely affect the quality of life of patients undergoing treatment. Although many advances have been made in reducing some of the toxicities associated with platinum drug therapy, it is clear that dose-limiting nephrotoxicity remains a major stumbling block in the use of this compound. Subtle changes in renal function occur without overt renal insufficiency, consisting of a decrease in effective renal plasma flow and tubular dysfunction despite aggressive hydratation. Early tubular damage occurring within 1 to 3 hours after cisplatin administration has been demonstrated by measurement of urinary beta 2-microglobulin, a sensitive marker of tubular injury. The chronic lesion has become of greater concern in recent years as many patients have been cured or placed into long-term remission due to cisplatin treatment. It consists of a decrease in glomerular filtration rate, which is not necessary characterized by a remarkable increase in serum creatinine. Cumulative tubular damage has been demonstrated by increased urinary excretion of tubular enzymes such as alanine aminopeptidase and beta 2-microglobulin. In this setting, predicting the occurrence of chronic cisplatin-induced nephrotoxicity remains a clinical challenge.
