title: [Resistance to the inhibitory effect of dexamethasone in brain tumor patients].
abstract: Out of 24 patients with brain tumors, 22 proved to be resistant to inhibition by dexamethasone. There were no significant differences in the sensitivity to dexamethasone in three study groups established on the basis of the tumor site-to-diencephalic structures distance. A relatively higher frequency of disturbances in dexamethasone inhibition in patients with brain tumors suggests grave disorders induced in glucocorticoid secretion regulation by chronic stress.
