title: The urinary excretion of corticosteroid sulfates by cancer patients.
abstract: Urinary excretions of free cortisol and corticosteroid sulfates were determined in 31 female controls, 77 breast cancer patients, 14 cases of colonic cancer, and 7 patients with bronchial carcinoma. Elevated corticosteroid sulfate excretion was present in 38% of patients with locally recurrent breast cancer and 30% of those with distant metastases, but in only 13% of the "early" breast cancer cases. A similar abnormality was seen in colonic cancer. Urinary free cortisol was usually normal. ACTH stimulation in a normal subject produced marked increases of both urinary free cortisol and corticosteroid sulfates. It is concluded that elevated corticosteroid sulfate excretion in cancer patients arises from an increased cortisol production rate combined with increased sulfurylation of the steroid. In bronchial carcinoma patients, changes similar to those occurring in the ACTH-treated normal subject may have resulted from ectopic ACTH production in the tumor.
