[The estimation of antioxidative vitamins concetrations in blood plasma of patients with neoplasms of gallblader and biliary tract].
Gallbladder and biliary tract cancer is a serious clinical problem. In-spite of wide range of new diagnostic and therapeutic methods, the significant improvement of treatment results, has not been noticed so far. The research about prevention methods, seems to be important, among the ways of improvement of the diagnosis and therapy outcomes of these diseases. It is related for example to study about one of the cause of biliary tract carcinogenesis--the imbalance between production of reactive oxygen species (ROS) and their inactivation by the antioxidative barrier. One of the components of this organism protection complex are antioxidative vitamins. The aim of this study was to measure the concentration of antioxidative vitamins (A, C, E, and beta-carotene) in serum, in patients with cancer of gallbladder and and biliary tract, in comparison to the results of healthy volunteers. The study groups comprised of 56 patients, both sexes with acute and chronic cholecystitis and with above-mentioned neoplasmas. The results shoved, that concentration of antioxidative vitamins in serum of patients with gallbladder and biliary tract cancer, was significantly decreased. The outcomes of this research, seem to confirm the participation of antioxidative barrier in inhibition of carcinogenesis of in those important parts of digestive system.
