TY - THES A1 - Kranz, Stefanie T1 - Morbidität von Nebennieren-Inzidentalomen mit (möglicher) autonomer Cortisol-Sekretion – Eine retro- und prospektive Studie mit dem Patientenkollektiv des Universitätsklinikums Würzburg von 1998 bis 2017 T1 - Morbidity of adrenal incidentalomas with (possible) autonomous cortisol secretion – A retro- and prospective study with the patient collective of the University Hospital Würzburg from 1998 to 2017 N2 - Aufgrund des zunehmenden Einsatzes von Schnittbildgebungen werden immer mehr Nebennieren-Raumforderungen zufällig entdeckt. Häufig ist bei diesen Zufallsbefunden („Inzidentalome“) laborchemisch eine „autonome Cortisol-Sekretion“ auffällig, ohne dass jedoch klinische Zeichen eines Glukokortikoid-Exzesses sichtbar wären. Ein florides Cushing-Syndrom führt bekanntermaßen zu einer erhöhten kardiovaskulären Morbidität und Mortalität. Ziel unserer Untersuchung war es, die Prävalenz kardiovaskulärer Risikofaktoren und Ereignisse bei Patienten mit einem Nebennieren-Inzidentalom zu ermitteln. Hierbei wurden die Adenome hinsichtlich ihrer sekretorischen Aktivität in drei Subgruppen eingeteilt („nicht-funktionell“, „mögliche autonome Cortisol-Sekretion“ und „autonome Cortisol-Sekretion“) und getrennt voneinander betrachtet. Die vorliegende Einzelzenter-Studie umfasst einen Zeitraum von 20 Jahren und beinhaltet sowohl retro- als auch prospektive Elemente. Insgesamt konnten 260 Patienten mit einem Nachsorgeintervall von durchschnittlich fast 9 Jahren inkludiert werden. Die Raten von arterieller Hypertonie, Diabetes mellitus und Dyslipidämie stiegen mit zunehmender Cortisol-Sekretion an; dies war sowohl bei der Erstdiagnose als auch bei der letzten erfassten Nachsorge zu beobachten. Patienten mit einem nicht-funktionellen Adenom wiesen nach der Erstdiagnose eine signifikant geringere Inzidenz kardiovaskulärer Ereignisse auf als Patienten mit einer autonomen Cortisol-Sekretion. Mittels einer multivariaten Cox-Regression wurden die Höhe des Serumcortisols im Dexamethason-Suppressionstest und eine positive Eigenanamnese als signifikante Einflussfaktoren für das Auftreten kardiovaskulärer Ereignisse ermittelt. Eine klinisch unterschwellige, jedoch chronische Cortisol-Exposition im Sinne einer autonomen Cortisol-Sekretion erhöht demnach das Risiko der betroffenen Patienten für die Entwicklung von Herz-Kreislauf-Erkrankungen. N2 - Due to the increased use of cross-sectional imaging, more and more adrenal masses are discovered incidentally. Frequently, these incidental findings ("incidentalomas") reveal "autonomic cortisol secretion" by laboratory tests, but without clinical signs of glucocorticoid excess. Florid Cushing's syndrome is known to lead to increased cardiovascular morbidity and mortality. The aim of our study was to determine the prevalence of cardiovascular risk factors and events in patients with adrenal incidentaloma. For this purpose, the adenomas were divided into three subgroups ("nonfunctional", "possible autonomous cortisol secretion" and "autonomous cortisol secretion") with respect to their secretory activity and are considered separately. The present single-center study covers a 20-year period and includes both retrospective and prospective elements. A total of 260 patients with an average follow-up period of almost 9 years were included. Rates of arterial hypertension, diabetes mellitus, and dyslipidemia increased with an elevated cortisol secretion; this was detected both at initial diagnosis and at the last follow-up. Patients with nonfunctional adenoma had a significantly lower incidence of cardiovascular events after initial diagnosis than patients with autonomic cortisol secretion. Using multivariate Cox regression, the level of serum cortisol in the dexamethasone suppression test and a positive self-reported history of cardiovascular events were found to be significant factors influencing the occurrence of cardiovascular events. Subclinical but chronic cortisol exposure in the sense of autonomic cortisol secretion thus increases the risk of affected patients for the development of cardiovascular diseases.

Specific data on the clinical and biochemical course of affected patients are lacking. Methods Retrospective study from a tertiary referral centre in Germany. After exclusion of overt hormone excess, malignancy and glucocorticoid medication, patients with adrenal incidentalomas were stratified according to serum cortisol after 1 mg dexamethasone: autonomous cortisol secretion (ACS), >5.0; possible ACS (PACS), 1.9-5.0; non-functioning adenomas (NFA), ≤1.8 µg/dl. Results A total of 260 patients were enrolled (147 women (56.5%), median follow-up 8.8 (2.0-20.8) years). At initial diagnosis, median age was 59.5 (20-82) years, and median tumour size was 27 (10-116) mm. Bilateral tumours were more prevalent in ACS (30.0%) and PACS (21.9%) than in NFA (8.1%). Over time, 40/124 (32.3%) patients had a shift of their hormonal secretion pattern (NFA to PACS/ACS, n=15/53; PACS to ACS, n=6/47; ACS to PACS, n=11/24; PACS to NFA, n=8/47). However, none of the patients developed overt Cushing’s syndrome. Sixty-one patients underwent adrenalectomy (NFA, 17.9%; PACS, 24.0%; ACS, 39.0%). When non-operated patients with NFA were compared to PACS and ACS at last follow-up, arterial hypertension (65.3% vs. 81.9% and 92.0%; p<0.05), diabetes (23.8% vs. 35.6% and 40.0%; p<0.01), and thromboembolic events (PACS: HR 3.43, 95%-CI 0.89-13.29; ACS: HR 5.96, 95%-CI 1.33-26.63; p<0.05) were significantly less frequent, along with a trend towards a higher rate of cardiovascular events in case of cortisol autonomy (PACS: HR 2.23, 95%-CI 0.94-5.32; ACS: HR 2.60, 95%-CI 0.87-7.79; p=0.1). Twenty-five (12.6%) of the non-operated patients died, with higher overall mortality in PACS (HR 2.6, 95%-CI 1.0-4.7; p=0.083) and ACS (HR 4.7, 95%-CI 1.6-13.3; p<0.005) compared to NFA. In operated patients, prevalence of arterial hypertension decreased significantly (77.0% at diagnosis to 61.7% at last follow-up; p<0.05). The prevalence of cardiovascular events and mortality did not differ significantly between operated and non-operated patients, whereas thromboembolic events were significantly less frequent in the surgical treatment group. Conclusion Our study confirms relevant cardiovascular morbidity in patients with adrenal incidentalomas (especially those with cortisol autonomy). These patients should therefore be monitored carefully, including adequate treatment of typical cardiovascular risk factors. Adrenalectomy was associated with a significantly decreased prevalence of hypertension. However, more than 30% of patients required reclassification according to repeated dexamethasone suppression tests. Thus, cortisol autonomy should ideally be confirmed before making any relevant treatment decision (e.g. adrenalectomy).
