Oxidative stress and tumor markers in cervical cancer patients.
|
| Abstract |
Cervical carcinoma is the second most common cancer worldwide. The extent of free radical induced oxidative stress can be exacerbated by the decreased efficiency of antioxidant defense mechanisms. Low levels of essential antioxidants in the circulation have been found to be associated with an increased risk of cancer. The aim of our study was to assess the extent of oxidative stress, the levels of antioxidants like superoxide dismutase (SOD), catalase (CAT), ceruloplasmin and to evaluate tumor markers such as aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP) and total sialic acid (TSA) levels in circulation of women with cervical carcinoma and to compare our findings with age matched controls. Low levels of SOD and CAT observed in the circulation of cervical cancer patients may be due to their increased utilization to scavenge lipid peroxides as well as sequestration by tumor cells. Higher levels of TSA, AST, ALT and ALP, in the circulation of cervical cancer patients may be used in the diagnosis and treatment monitoring of patients with cervical carcinoma.
