[The effect of surgery on free-radical reactions in patients with lung cancer]

The effect of surgery on free-radical reactions in patients with lung cancer was studied vis-a-vis extent of intervention. To this end, blood components and exhaled air condensate were monitored. Surgery was found to aggravate the imbalance in the "lipid peroxidation-antioxidants" system in those operated on. The data obtained make a case for application of antioxidants in complex treatment of lung cancer. Said parameters were evaluated versus incidence of early postoperative lung-pleura complications. Preoperative criteria for prognosis of postoperative complications have been worked out.
