Evaluation of the use of N-acetylcysteine attenuating cisplatin-induced toxicities by oxidative stress in head and neck cancer patients


Head and neck cancer corresponds to tumors located in the upper aerodigestive tract, such as the oral cavity, pharynx and larynx. The most effective treatment consists of high doses of cisplatin chemotherapy and radiotherapy, however, their use is limited due to toxicities caused mainly by oxidative stress. The objective of this study will be evaluate the use of n-acetylcysteine attenuating cisplatin-induced toxicities by oxidative stress in head and neck cancer patients. This is a randomized double-blind placebo-controlled clinical trial with consecutive sampling that will be conducted at Oncology Department of Clinic Hospital / UNICAMP. Head and neck cancer patients who will begin cisplatin antineoplastic treatment (80-100mg/m2 on days 1, 22 and 43) and concurrent radiotherapy will be included in this research. They will be studied in 2 groups (n-acetylcisteine and placebo). All patients will be evaluated in relation to cisplatin induced hematologic and gastrointestinal disorders, nephrotoxicity, ototoxicity, and hepatotoxicity; plasmatic and celular oxidative stress; quality of life; and pharmacoeconomic evaluation. Results will be statistically analysed using Chi-square, Fisher, Mann-Whitney, and ANOVA for repeated measures tests (p<0.05.) (AU)
