GastroEnteroPancreatic and Thoracic Neuroendocrine Tumors and the Ectopic Adrenocorticotropin Syndrome

#1142

Introduction: Ectopic Adrenocorticotropin (ACTH) Syndrome (EAS) is associated with a variety of malignancies, predominantly of neuroendocrine origin. Several series report on the relative contribution of EAS in the spectrum of Cushing’s syndrome. However, information on the incidence/prevalence and prognosis of EAS in the setting of patients diagnosed with Thoracic or GEP-NETs is virtually absent.

Aim(s): Screening of a large consecutive series of thoracic and GEP-NET patients for the presence/occurrence of EAS in a retrospective case-record study in a tertiary academic referral center.

Materials and methods: 918 patients diagnosed with thoracic or GEP-NETs between 1993-2012 were studied. MEN1 & SCLC were excluded. We differentiated between synchronous, metachronous and cyclic occurence of EAS. Synchronous EAS was defined as 6 months before and 6 months after first diagnosis of thoracic or GEP-NET. Overall survival was analyzed using a KM curve.
