Antioxidant status in patients with bladder cancer regarding cancer stage and grade

The imbalance of antioxidants and pro-oxidants plays a crucial role in the carcinogenesis of bladder cancer (BC). This study aimed to evaluate serum antioxidant status in patients with BC and determine its potential use in the diagnosis and progression potential considerations following histopathological assessment. A cross-sectional study included 90 patients with BC, divided into Ta, T1, and T2–T4 stage subgroups, and according to cancer progression potential, into low-grade (LG) and high-grade (HG) subgroups. The control group (CG) included 30 healthy volunteers. Antioxidant status was determined using the spectrophotometric method and standard laboratory tests. Serum superoxide dismutase activity was significantly higher in BC patients regarding cancer stage in comparison to the CG (p
