BACKGROUND Chromosomal instability is observed in a wide spectrum of human cancer syndromes. However, to date, little is known of the characteristic genetic changes in sporadic neuroendocrine tumours of the gastroenteropancreatic system. AIMS AND METHOD We have studied copy number aberrations (CNAs) in 26 sporadic neuroendocrine tumours of the enteropancreatic system (12 foregut and 14 midgut...

objective(s): the objectives of this work was to assess the benefits of the application of physiologically based pharmacokinetic (pbpk) models in patients with different neuroendocrine tumours (net) who were treatedwith lu-177 dotatate. the model utilises clinical data on biodistribution of radiolabeled peptides (rlps) obtained by whole body scintigraphy (wbs) of the patients.methods: the blood...

BACKGROUND Proteasomal subunit PSMB4 was suggested to be a survival gene in an animal model of hepatocellular carcinoma and in glioblastoma cell lines. In pulmonary adenocarcinoma, a high expression of these genes was found to be associated with poor differentiation and survival. This study investigates the gene expression levels of 26S proteasome subunits in human pulmonary neuroendocrine tumo...

Neuroendocrine tumours of the gastroenteropancreatic tract (GEP-NETs) comprise a group of very heterogeneous neoplasms, which are considered 'rare diseases'. Epidemiological studies on the incidence of GEP-NETs worldwide have reported a remarkable increase in the detection of these tumours. In a recent study, based on pathology reports (PALGA) to investigate the incidence of pancreatic and duod...

BACKGROUND Gastric neuroendocrine tumours (NETs) are increasingly recognised, and management decisions may be difficult due to an incomplete understanding of aetiology, natural history and optimum therapy. This article presents a current understanding based on recent advances in epidemiology, classification, molecular profiling, and treatment. METHODS Relevant medical literature was identifie...

Neuroendocrine gut and pancreatic tumours have provided a diagnostic and therapeutic challenge over the years. These rather slowly growing neoplasms have been assigned a good prognosis but when liver metastases are present the prognosis is not better than that of most other malignant tumours. Despite the development of improved diagnostic procedures many patients are still referred at a stage o...

CONTEXT Pancreatic neoplasms are an uncommon aetiology of acute pancreatitis. Pancreatic neuroendocrine tumours are a rare subgroup of pancreatic neoplasms. CASE REPORT We report on three patients having acute pancreatitis secondary to pancreatic neuroendocrine tumours, one of them with severe pancreatitis, and review the published cases up to now. Only 22 patients with acute pancreatitis sec...

Background Neuroendocrine tumours (NETs) are a heterogeneous group of diseases that can originate from any part of the gastrointestinal tract, bronchi, thyroid and pancreas. These tumours may be functioning or not depending on their ability to produce active substances, such as adrenocorticotrophic hormone (ACTH). ACTH-producing pancreatic neuroendocrine tumours are rare, with limited data abou...

Neuroendocrine tumours (NETs) are rare pathologies which origin from neuroectodermic and endodermic cells and that can produce peptides and amino acids. About 70% of NETs derive from gastroenterohepatic (GEP) system and the other 30% from the different sites through the body. They are distinguished into single and multiple localizations and also into sporadic, familial multiple endocrine-relate...

Primary hepatic neuroendocrine tumours are rare tumours effecting relatively young patients. As metastatic neuroendocrine tumours to the liver are much more common, extensive investigations are crucial to exclude a primary tumour elsewhere. We report a case of a 27 year old woman who presented with fatigue, increased abdominal girth and feeling of early satiety and bloating. Extensive work up f...
