OBJECTIVE: Owing to their increasing rate of discovery as incidental findings, the characterization of adrenal masses is an important diagnostic problem which frequently challenges the clinician's skill. DESIGN: The results of dehydroepiandrosterone sulfate (DHEAS) measurement were evaluated in a consecutive series of 107 patients with an adrenal mass (39 men, 68 women aged 15-81 years, median 56 years). DHEAS levels observed in the patients were categorized as reduced, normal or elevated according to sex- and age-adjusted reference ranges obtained by measuring DHEAS in 214 healthy women and 142 healthy men aged 17-93 years. The working hypothesis was that a low DHEAS level is a marker of benignity. METHODS: In 84 patients, the adrenal mass was discovered serendipitously, while in the remainder the mass was clinically symptomatic. Patients with known extra-adrenal malignancies were excluded. The adrenal masses were categorized as benign or malignant by computerized tomography (CT) criteria. All patients with suspected malignant tumors or with overtly hypersecreting tumors underwent adrenalectomy. The patients with a presumptive benign tumor were followed-up for at least 12 months. RESULTS: In the overall series, the sensitivity and specificity of a low DHEAS level in the identification of a benign lesion were 41% and 100% respectively. Superimposable figures were obtained when considering only adrenal incidentalomas. DHEAS levels in adrenal cancers displayed some overlap with adrenal adenomas, but in only 2/11 adrenal cancers were DHEAS levels normal, while they were elevated in the remainder. CONCLUSIONS: The present data suggest that DHEAS measurement may help to differentiate benign from malignant adrenal masses as a complementary test of CT in a clinical research setting. The value of DHEAS measurement in general practice is limited because it may be difficult to differentiate between low and low-normal values, particularly in the elderly.

DHEAS levels observed in the patients were categorized as reduced, normal or elevated according to sex- and age-adjusted reference ranges obtained by measuring DHEAS in 214 healthy women and 142 healthy men aged 17-93 years. The working hypothesis was that a low DHEAS level is a marker of benignity.
