Abstract

Cisplatin is used to treat a variety of tumors, including head and neck tumors. Its use is limited due to its toxities, mainly nephrotoxicity, which is caused by oxidative stress. The aim of this study was to evaluate microRNAs (miRNAs) and oxidized biomolecules as possible biomarkers of cisplatin-induced nephrotoxicity. Blood samples were collected from 81 head and neck cancer patients before (baseline) and after 5 (D5) and 20 (D20) days following cisplatin administration (80-100 mg/m2) for toxicity assessment, which were classified into grades according to Common Terminology Criteria for Adverse Events v4.0. The plasmatic oxidative stress biomarkers, malondialdehyde (MDA) and carbonylated proteins, and urinary oxidative stress biomarker, 8-isoprostane, were measured at baseline and D5. MiRNAs were extracted from plasma and urine collected at D5 from 6 patients with and 6 patients without nephrotoxicity, constituing the nephrotoxicity and no nephrotoxicity groups, respectively...
