Gastro-entero-pancreatic neuroendocrine neoplasms (GEP-NENs) originate from diffuse endocrine system (DES). Over 50% of diagnosed neuroendocrine neoplasms (NENs) are carcinoid tumors, secreting mainly serotonine. The incidence of carcinoids in general population is estimated to be 2.9 cases/100000 inhabitants/year. In our study we aimed at analyzing retrospectively patients with diagnosed carcinoid tumors, hospitalized between the years 2001 and 2012 in the Department of Endocrinology and Diabetology of Nicolaus Copernicus University Collegium Medicum in Bydgoszcz. The study group consists of 39 patients (20 women and 19 men) aged between 36 and 70, with diagnosed carcinoid. All patients have determined chromogranin A concentration (CgA), urinary excretion of 5-hydroxyindoleacetic acid (5-HIAA) in 48-hours urine sample, urinary excretion of catecholamine hormones (norepinephrine, epinephrine and dopamine), vanillylmandelic acid (VMA) and homovanillic acid (HVA) in 24-hours urine sample. Ultrasonography (US), computed tomography (CT), magnetic resonance imaging (MRI), endoscopic ultrasound (EUS) and somatostatin receptor scintigraphy (SRS) with 99mTc-Depreotide have been performed. The diagnosis of the carcinoid tumor is often problematic because of its slow growth and uncharacteristic symptoms. And often the localization of the primary tumor cannot be determined. Somatostatin analogues can help to control symptoms of the carcinoid syndromeReferences
