Cushing syndrome due to ectopic (adrenocorticotropic hormone) ACTH secretion (EAS) constitutes approximately 10% of Cushing’s syndrome (CS). In this group only in about 5% cases pheochromocytoma is the source of ACTH.We present two patients with EAS by pheochromocytoma.1. A 70 year-old woman with 3-months history of malaise, weakness, abdominal pain, loss of weight and appetite, hypertension and diabetes mellitus. One month ea...

GEPNETs are rare tumors of very variable biology, particularly proliferative potential. Improved knowledge of the clinical course of disease may lead to proper identification of patients requiring more aggressive approach.Aim: i) characteristics of GEP-NET patients of the Endocrinology Department, University Hospital in Krakow, Poland; ii) identification of factors influencing their 5-year survival.Material and methods: Study inclu...

Cancer registers are important tools in improving the knowledge of epidemiology of rare malignancies, such as gastro-entero-pancreatic neuroendocrine tumors.Aim: To assess the epidemiology of GEPNETs in Krakow and Krakow district area between January 2007 and December 2011.Material and methods: To assess the epidemiology of GEPNETs in Krakow area a register was created, based on independent sources of information. 88 patients (49 f...

Abstract Identification of factors influencing survival of the gastro-entero-pancreatic neuroendocrine tumors patients may improve their management by better selection of subjects requiring more closed follow-up and more aggressive therapeutic approach.Aim: To assess factors influencing survival of GEPNET patients livingin Krakow and Krakow district area.Material and methods: The data from GEPNETs register run in t...

Introduction: The aim of this study was to assess the survival rate of patients with disseminated or inoperable neuroendocrine tumors (NETs) after PRRT with the use of 90Y-DOTATATE combined with long acting somatostatin analogue.Materials and methods: 72 patients were treated with PRRT in our Department. The 90Y-DOTATATE therapeutic activity was calculated per total body surface area up to a total of 7.4 GBq/m2 administra...

Cushing’s syndrome caused by ectopic ACTH secretion (EAS) constitutes ~10% of Cushing’s syndrome (CS).The aim of this study was to present experience of our Clinic with EAS.).Patients: Twelve patients, aged 14–70 years: four females and eight males.Outcomes and measurements: Clinical features, medical examination, morning electrolytes, glucose level, serum cortisol, ACTH levels, midnight plasma...

Introduction: The aim of this study was to assess the efficacy of peptide receptor radionuclide therapy (PRRT) with the use of 90Y-DOTATATE and the survival rate of patients with disseminated or non-operable neuroendocrine tumors (NETs).Methods: In the time period from June 2006 to October 2012, 70 patients were treated with PRRT in our department. The 90Y-DOTATATE therapeutic activity was calculated per total body surface area up t...

The incidence of gastric neuroendocrine tumors (GNT) is increasing, what can be explained by the increased detection caused by the common use of the endoscopy and the pervasive use of acid suppressive therapy leading to enterochromatofine like cells proliferation. There are numerous new diagnostic/therapeutic GNT methods in use like: EUS, SRS, somatostatin therapy and 90Y/177Lu-DOTA-TATE radiotherapy.Materials and methods: In 1998–2008 37 patients w...

Background: NETs are rare tumours arising from dispersed neuroendocrine system. Nevertheless, their estimated prevalence increased lately, mostly due to progress in imaging, biochemical and histopathological diagnostics.The aim of the study was to present the characteristics of the NETs patient surveyed in our Endocrinology Department since 2000.Material and methods: One hundred and fifty-eight patients (males – 42.4%, females...

Despite a wide spectrum of imaging diagnostics, GEP-NETs often stay undetectable until the time of dissemination. Removing of a primary tumour together with disseminated lymph nodes even with the presence of liver metastases is the most appropriate treatment to delay progression of the disease. SRS followed by RGS gives a possibility to detect occult GEP-NET intra-opratively. 99mTc-HYNIC/EDDA-octreotate, a somatostatin analogue with high affinity to sst2 was applied...
