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. 展开更多

Primary etiological factors include cirrhosis, hepatitis, aflatoxin and alcohol. The current study was conducted to determine cytosolic erythrocyte carbonic anhydrase and catalase enzyme activities and levels of some trace elements. For this purpose, 40 patients with primary and metastatic hepatic cancer and 29 healthy volunteers enrolled to the study. Catalase and carbonic anhydrase enzyme activities and serum trace element levels were measured in patient and control groups. In the current study, serum copper, magnesium, manganese and zinc levels were lower in the primary and metastatic hepatic cancer group in comparison with the control group (P < 0.05). In contrast, serum iron, cobalt, cadmium and lead levels were higher in the patient relative to the control group (P < 0.05). In comparison with the control group, the catalase level was lower in primary and metastatic cancer group, while the carbonic anhydrase level was higher in the cancer group (P < 0.05). Changes in levels of trace elements and anti-oxidant enzymes may be the factors which influence the development and progression of liver cancer. The carbonic anhydrase enzyme can be a useful indicator in the diagnosis of cancer. However, this issue warrants further investigation. 展开更多
