title: [Parameters of oxidative stress in patients with gastric cancer].
abstract: We studied effect of the neoplastic process and surgical treatment on parameters of the oxidative system in patients with stomach cancer including serum and gastric tissue levels of malonic dialdehyde, lactic and pyruvic acids in stage I-IV malignancy before and after radical surgery. The development and generalization of the neoplastic process are associated with the activation of oxidative reactions leading to endotoxicosis. Specific anticarcinogenic treatments (including surgery) aggravate changes in the oxidative systems and further deteriorate quality of life and tolerance of the treatment.
