[Changes in the hypophyseal somatotropic hormone (STH) levels in cancer patients]

Somatotropin levels were compared in 337 cancer patients and controls, using radioimmunological methods. Lung and gastric cancer patients revealed relatively greater variations in its basal levels. This proved to be a paradoxical reaction to operative stress. The said reaction is attributed to disturbances which develop in the somatotropin self-regulation system of cancer patients.
