title: Selenium concentrations in serum of patients with cerebral and extracerebral tumors.
abstract: The concentrations of serum selenium were measured by atomic absorption spectrophotometry in 139 patients with tumors in cranium cavity. The data from patients were compared with those from a reference group of 294 healthy adult individuals. The serum concentrations of selenium is significantly decreased (p less than 0.001) in patients with malignant tumors. The authors discuss the possibilities for treatment of malignant tumours of central nervous system with selenium.
