Tumor host relations. I. Increased plasma cortisol in tumor-bearing humans compared with patients with benign surgical diseases.
Plasma cortisol was measured by a protein binding technique in 81 patients with malignant tumors of different extent and various sites and in 82 patients with benign surgical diseases. The mean value of the tumor patients (x +/- s = 165 +/- 69 micrograms cortisol/l plasma) was increased significantly compared with the benign surgical disorders (100 +/- 45 micrograms/l). Within the group of patients with benign surgical disorders there was little variation by the type of disease (cortisol mean values given in brackets): benign breast tumors (95), gall stones (107), ulcer of the stomach and duodenum (96), hernia (78), appendicitis acuta (112), and struma (90). The results are in accordance with the hypothesis that glucocorticoids are involved in the increased protein catabolism of skeletal muscles and other signs of cachectic tumor patients.
