[Excretion of corticosteroids and catecholamines in cancer of the rectum and stomach].

In patients with cancer of the rectum and stomach the excretion of 17-ketosteroids was reduced, compared with the normal level, most of these patients showing a decreased adrenal glucocorticoid function too. In patients with cancer of the gastrointestinal tract adrenaline and noradrenaline excretion was lower than normal values. There is a distinct correlation between the indices of catecholamines and corticosteroids excretion in the urine of patients with rectal and gastric cancer.
