  • Title: [Nephropathy in Patients Undergoing Cancer Drug Therapy - Platinum Derivatives(Cisplatin and Carboplatin)].
    Author: Matsuoka A, Ando Y.
    Journal: Gan To Kagaku Ryoho; 2017 Mar; 44(3):200-203. PubMed ID: 28292990.
    Abstract:
    Cisplatin, a first-generation platinum derivative, is one of the most widely used anticancer agents and can treat a broad spectrum of malignancies. Cisplatin-induced nephrotoxicity is a major dose-limiting side effect resulting from damage to the proximal tubules of the kidney. This nephrotoxicity can be prevented by lowering the concentration of cisplatin and shortening the period of cisplatin exposure to the proximal tubules. In clinical practice, high-volume hydration(>3 L intravenous isotonic saline), forced diuresis(mannitol and/or furosemide), and magnesium supplementation have been generally used to lower the risk of cisplatin-induced nephrotoxicity. Short hydration(short-term, low-volume hydration with oral fluid intake)has recently been undertaken among patients with reserved renal function and good performance status, especially in outpatient settings. Carboplatin is a second-generation platinum-based agent that is almost completely excreted from the kidneys following its administration. Its pharmacokinetics can be predicted based on the glomerular filtration rate(GFR). The area under the blood concentration-time curve(AUC), an indicator of drug exposure volume in the body, is closely correlated with hematotoxicity and antitumor effect. It is now a widespread practice to set carboplatin doses based on the GFR after establishing a target AUC. This article describes the characteristics of these 2 platinum-based drugs, focusing on the recommendations based on the recently published guidelines regarding nephropathy in patients undergoing cancer drug therapy.
