Introduction: Breast cancer in women is most common cancer world wide and second most common cancer overall. Trace elements and antioxidant enzymes have been found involved in development and prevention of malignancies including breast cancer. This study aims to find out association between trace elements: copper, zinc and selenium along with antioxidant enzymes: SOD, Catalase, Glutathione peroxidise levels in breast cancer patients of various clinical stages. Materials & Methods: This Prospective observational cohort study is conducted in department of general surgery, King George's Medical University, Lucknow, U.P., India. Blood sample of 152 breast cancer patients were analysed and age matched with 152 controls. Unpaired t-test is used to compare the antioxidant enzymesand trace elements between cases and controls. The plasma level of copper, zinc, selenium and antioxidant enzymes (SOD, Catalase, Glutathione peroxidase) were analysed in both groups to find out any statistically significant correlation. Results: Plasma copper levels (μgm/dl) are higher in cases with mean of 132.43±6.10 vs controls 113.58±11.70 with p<0.0001. Plasma zinc levels (μgm/dl) (case: 88.25±6.30, control: 109.92±8.33, p<0.0001)) and selenium (μmol/dl) (case:3.27±0.18, control: 3.33±0.22 (p<0.0001)) are lower in breast cancer patients. Mean levels of Superoxide dismutase (IU/ ml) (case: 9.49±6.25, control: 27.04±4.39, p<0.0001), Catalase (IU/ ml) (case:0.09±0.08, control: 0.29±0.24, p<0.0001) and Glutathione peroxidise (nanomolNADPH oxidase/min/mg protein) (case: 16.96±10.20, control; 46.70±14.18, p<0.0001) are observed to be lower in breast cancer patients. Blood level of selenium, Superoxide dismutase, Catalase and Glutathione peroxidase are found to have a direct correlation while Plasma levels of Copper has inverse correlation with advanced stages of breast cancer Conclusion: Lower levels of antioxidant enzymes (Superoxide dismutase, Catalase and Glutathione peroxidase) and selenium found in breast cancer patients along with higher copper levels suggest that these metals and antioxidant enzymes play role in etiopathogenesis and aggressiveness of disease. This gives insight to initiate research for additive therapy of antioxidants and selenium in patients of breast cancer to achieve better outcome. Disclosure of Interest: None Declared.
