ABSTRACT

In the present work we examined selected parameters of antioxidant status in patients with primary colorectal cancer and liver metastasis of colorectal cancer. Total antioxidant status (TAS), activity of superoxide dismutase (SOD) and catalase (CAT) were examined in colorectal primary cancer, liver metastasis of colorectal cancer and in blood serum of patients before and after surgery. It was found that patients have disordered function of the the antioxidant system. This is demonstrated by decreased TAS and changes in the activity of SOD and CAT, both in tumor tissue and blood serum.
