Objectives: Elevated levels of lipid peroxidation and changes in the concentration of enzymatic and non-enzymatic antioxidant systems have been reported in various cancers, but there are very few reports available of lipid peroxidation due to oxidative stress in patients with intracranial neoplasms. The purpose of this study was to assess alterations in lipid peroxidation and antioxidant status in different types of tumors and to compare the results with their relative peritumoral tissues and compare the oxidative status in different grades of tumors.

Patients And Methods: We investigated the extent of oxidative stress and the levels of antioxidants in 16 astrocytomas and 38 other different types intracranial tumors comparing the results with their corresponding peritumoral tissues and comparing the levels in between low-grade and high-grade tumors.
