dc.description.abstractThe aim of this study was to assess the oxidative stress and the genotoxicity induced by chemotherapy by the determination of plasma malondialdehyde (MDA) level, protein carbonyl (PC) content, superoxide dismutase (SOD) activity and lymphocyte DNA damage in Algerian children with lymphoma. The study population included thirty patients with lymphoma and fifty healthy controls. Patients were treated with 2 courses of OEPA (oncovin 1,5 mg/m(2), etoposide 125 mg/m(2), prednisone 60 mg/m(2) and doxorubicin 40 mg/m(2)) followed by 2 to 4 courses of COPDAC (cyclophosphamide 500 mg/m(2), oncovin 1,5 mg/m(2), dacarbazine 250 mg/m(2) and prednisone 40 mg/m(2)). Plasma levels of MDA, PC and SOD were spectrophotometrically measured. DNA damage was assessed by alkaline comet assay in peripheral blood leukocytes. Plasma MDA, PC levels and lymphocyte DNA damage, were found to be significantly higher in lymphoma patients than in controls (p < 0.001). Whereas, SOD activity in lymphoma patients was significantly lower than in healthy controls (p < 0.001). There were significant positive correlations between DNA damage, MDA and PC in patients (r = 0.96, p < 0.001, r = 0.97, p < 0.001, respectively), and negative correlation with SOD (r = -0.87, p < 0.01). Our results indicated that, leukocytes DNA damage and oxidative stress were significantly higher in lymphoma patients, suggesting that the direct effect of chemotherapy and the alteration of the redox balance may influence oxidative/antioxidative status.
