Evaluation of Lipid Peroxidation and Some Antioxidant Activities in Patients with Primary and Metastatic Liver Cancer

Abstract: HCC is the 6th most common cancer in the world. The main risk factors associated with HCC are hepatitis B (HBV) and hepatitis C viral infections and other factors that play a role in HCC development, include aflatoxin B1 (AFB1) cigarette smoking, and chronic inflammation. The aim of this study is to investigate lipid peroxidation and some antioxidant enzyme activities in patients with primary and metastatic liver cancer. For this purpose, 25 primary and metastatic liver cancer patients and 15 healthy controls were included in the study. In blood samples taken from the patient and control groups, the main product of lipid peroxidation MDA and SOD, GSH, GPx activity levels were examined. In result of study serum MDA level is higher and erythrocyte SOD, GSH, and GPx activities were found to be significantly lower in the patient group compared with the control group (p < 0.05). As a result, liver cancer is associated with oxidative stress and antioxidant system weakens, which is an important indicator of oxidative stress, lipid peroxidation levels increased and promotes the tissue damage.
