Evaluation of Oxidative Stress, Anti-Oxidant, Vitamins and Co-Factor Elements in The Sera of Gastric Cancer in Iraqi Patients.

Abstract

The objective of this study is to analyze oxidative stress markers Total Oxidant Status (TOS) and total Antioxidant Status (TAS), assess antioxidant levels (vitamin C, E), and evaluate co-factor element profiles zinc (Zn), copper (Cu), iron (Fe) in the serum of Iraqi gastric cancer patients. By elucidating these relationships, the research aims to enhance knowledge on oxidative stress, dietary factors, and potential therapeutic approaches for managing nutritional imbalances in this cohort. The study included 60 gastric cancer patients and 60 matched controls. Blood samples were collected and serum was extracted for analysis of TOS, TAS, Vitamin C, Vitamin E, copper, zinc, and iron levels. Measurements were conducted using spectrophotometry and ELISA kits from various companies. Statistical analysis was performed with IBM SPSS 25.0, presenting results as means ± SD, and differences between groups were assessed via independent samples t-test at p < 0.05 and p ≤ 0.01. The study results indicated statistically significant differences between gastric cancer patients and controls in various biomarkers, with all comparisons showing p-values less than 0.001. This suggests strong evidence for the observed differences between the two groups in (TOS), (TAS), vitamins C and E, Cu, Zn, and Fe levels. These relationships underscore the intricate connections among biomarkers in gastric cancer pathophysiology. The study underscores the intricate relationship between oxidative stress, antioxidant depletion, and micronutrient imbalances in gastric cancer. These findings offer valuable insights into the disease's pathophysiology, indicating potential diagnostic biomarkers. Further research is warranted to unravel underlying mechanisms and explore clinical applications for early gastric cancer diagnosis.
