[Retrospective hormonal analysis of incidentally discovered and operated adrenal tumors for subclinical Cushing's syndrome].

| Abstract |
In the last twenty years the introduction of new imaging techniques has caused increasing incidence of accidental detection of adrenal tumors, which are usually mild and in most cases are hormonally inactive adenomas. Among hormonal disorders in patients with adrenal incidentalomas the hypercortisolism is often described, which, if not treated properly, leads to multiple organ complications, and further to the patient's death. The aim of the study was the retrospective analysis of the group of patients with adrenal incidentaloma, verified by histopathology for assessment of subclinical Cushing's syndrome. Among the group of 225 patients: 62 men and 163 women with incidentally detected adrenal tumors in age from 19 to 81 years diagnosed and treated in the Department of Clinical Endocrinology, University Hospital in Krakow, 59 patients was sent to surgery: 15 men and 42 women. Two groups of patients were analysed, divided on the basis of histopathological examination result. Group A consisted of patients with adrenal cortical adenoma: 38 people (11 men and 27 women). In group B there were people with so-called other hormonal inactive adrenal tumors - 17 people (4 men and 13 women). The average age of the patients in group A was 52.05 +/- 11.52 years, in group B 51.44 +/- 14.14 years. In group A the mean morning level of cortisol was 18.23 +/- 6.42 ug/dl and did not differ statistically significantly from the results of group B (mean morning cortisol level of 15.86 +/- 4.6 ug/dl). However a significantly higher nocturnal cortisol levels in the blood serum of patients with group A versus group B was observed (6.78 +/- 5.65 ug/dl vs. 3.57 +/- 1.77 ug/dl). There was no cortisol diurnal rhythm disorders in group B, while in group A slightly disrupted cortisol diurnal rhythm was found in 17 people. Mean values of 24-hour urine 17-OHCS and free cortisol were statistically higher in group A than in group B, although mean values remained within normal limits. In 24 patients from group A where abnormalities in the screening test with 1 mg DXA were found, a test with 2 and 8 mg was performed, which showed incomplete suppression of the excretion of steroid metabolites in the urine after administration of 8 mg in 17 subjects, and 3 of the total absence of suppression. In group B in 4 people there was no suppression in 1 mg of DXA test, while the suppression test with 8 mg of DXA was normal. A detailed analysis of the clinical signs, meticulously carried out and repeated hormonal diagnosis with the use of functional tests should be focused on the detection of subclinical hormonal disorders, which is crucial in preventing organ damage and making a decision of the right treatment of the patient, which is surgical.
