Abstract
Tumor lysis syndrome (TLS) is characterized by hyperuricaemia, hyperphosphatemia, hyperkalaemia, as well as hypocalcaemia due to the breakdown of tumor cells undergoing cancer therapy (chemo/radio). Therefore it is of interest to evaluate oxidative stress using selective biological markers [Malondialdehyde (MDA), Superoxide Dismutase (SOD), Glutathione (GSH) and Catalase (CAT)] in TLS. We report the marked differences ( statistically significant with control) observed among a selected set of biomarkers of oxidative stress (MDA = 8.66 +/- 1.37; SOD = 0.15 +/- 0.11; GSH = 2.25 +/-.77; CAT = 0.76 +/-.57) in TLS patients in addition to other conventional biomarkers. Moreover, correlation was investigated among the parameters of oxidative stress and other circulating biomarkers of TLS. Data suggest the use of SOD, MDA, and GSH as potential diagnostic biomarker for TLS with other biomarkers.
