title: Oxidative stress and antioxidant status in cervical cancer patients.
abstract: Cervical cancer (CaCx) is a global public health problem as it is the second most common cancer leading to the death of women worldwide. Many references revealed that the low levels of antioxidants induce the generation of free radicals leading to DNA damage and further mutations. In the present study attempt have been made to evaluate the levels of serum Lipid peroxide, Nitric Oxide (NO(.)) Erythrocytic-Superoxide Dismutase (RBC-SOD), Vitamin-C, serum Copper (Cu) and serum Zinc (Zn). 120 patients were divided in 4 groups according to the increasing CaCx stages i.e. stage I, II, III & IV respectively. All the patients were around the age group of 25-65 years. 30 healthy women between the same age group were treated as controls. Highly significant increased values of MDA, NO(.) and Cu were observed (p<0.001) whereas the activity of RBC-SOD, levels of Vitamin-C and Zn were significantly decreased in CaCx patients as compared with healthy controls (p<0.001). Cu/Zn ratio was found to be altered in CaCx patients. From our findings it can be concluded that the oxidative stress is induced among CaCx patients, which inturn increases the risk of CaCx.
