Gastroenteropancreatic neuroendocrine tumors (GEP/NET) are unusual and rare neoplasms that present many clinical challenges. They characteristically synthesize store and secrete a variety of peptides and neuroamines which can lead to the development of distinct clinical syndrome, however many are clinically silent until late presentation with mass effects. Management strategies include surgery cure and cytoreduction with the use of somatostatin analogues. Somatostatin have a broad range of biological actions that include inhibition of exocrine and endocrine secretions, gut motility, cell proliferation, cell survival and angiogenesis...

Multiple endocrine neoplasia type 1 (MEN1) is a hereditary cancer syndrome caused by germline mutations of the MEN1 gene located in chromosome 11q13. In patients with MEN1, multicentric tumors develop in the involved organs; however, precise evaluation of genetic changes in these multicentric tumors has not been performed. In the present study, using whole-exome sequencing, we analyzed germline and somatic genetic changes in blood cells, two pancreatic endocrine tumors and one duodenal tumor obtained from a patient with MEN1 gastrinoma...

The treatment of hormone hypersecretory syndromes caused by neuroendocrine tumors (NETs) can be a major challenge. NETs originating from the small intestine often secrete serotonin causing flushing, diarrhea and valve fibrosis, leading to dehydration or heart failure in severe cases. NETs from the pancreas can secrete a wider variety of hormones, like insulin, glucagon and gastrin leading to distinct clinical syndromes. Historically mortality in patients with functioning NETs was high due to the complications caused by the hypersecretion of hormones...

SUMMARY: A 54-year-old man had gastrinoma, parathyroid hyperplasia and pituitary tumor. His family history indicated that he might have multiple endocrine neoplasia type 1 (MEN1). MEN1 gene analysis revealed a heterozygous germline mutation (Gly156Arg). Therefore, we diagnosed him with MEN1. Endocrinological tests revealed that his serum prolactin (PRL) and plasma adrenocorticotropic hormone (ACTH) levels were elevated to 1699 ng/mL and 125 pg/mL respectively. Immunohistochemical analysis of the resected pancreatic tumors revealed that the tumors did not express ACTH...

The existence of primary lymph node (LN) gastrinoma is questionable and controversial. In fact, the presence of gastrinoma in such uncommon site raises the possibility of metastasis from another occult primary site. An extensive evaluation and careful follow-up is always warranted. A female aged 48 years presented with chronic abdominal pain and watery diarrhoea. Her serum gastrin and chromogranin were elevated, and an underlying gastrinoma was suspected. Further evaluation with an octreotide scan, an endoscopic ultrasound and a secretin stimulation test confirmed the diagnosis...

BACKGROUND: The multiple endocrine neoplasia type 1 syndrome (MEN1) natural history is poorly evaluated, and few single-institution experiences about hereditary gastroenteropancreatic neuroendocrine tumors (GEP-NET) are reported. Our purpose is to analyze the role of GEP-NET in MEN1-related death, as well as the behavior of these lesions during follow-up. METHODS: The study population consists of 77 patients diagnosed with MEN1 GEP-NET, regularly followed up since 1990...

INTRODUCTION: Pancreatic neuroendocrine neoplasms (pNENs) are relatively rare tumors representing 1% to 2% of all pancreatic neoplasms. These tumors can secrete a variety of biologically active substances giving rise to distinct clinical symptoms or can be clinically nonfunctioning. Apart from insulinomas and gastrinomas, which constitute the majority of functioning pNENs, some tumors may secrete serotonin presenting with the features of the carcinoid syndrome. These so-called pancreatic carcinoids are considered relatively rare tumors and are associated with increased urinary levels of 5-hydroxyindoleacetic acid (5-HIAA)...

Zollinger-Ellison syndrome (ZES) is a rare clinical disorder, characterized by hypersecretion of gastric acid and multiple ulcers distal to the duodenal bulb. This occurs via the release of gastrin by neuroendocrine tumors known as gastrinomas. Patients with ZES present with nonspecific GI symptoms, which often leads to a delay in diagnosis. Our patient is a 55-year-old female with chronic abdominal pain, nausea, and diarrhea. She underwent EGD, EUS, MRCP, CT scans, and cholecystectomy, which did not reveal the cause of her symptoms...

BACKGROUND AND OBJECTIVES: Imaging of the pancreas for detection of neuroendocrine tumors is indicated as surveillance in multiple endocrine neoplasia type 1 (MEN1) or if typical clinical symptoms combined with hormone production raise the suspicion of a neuroendocrine tumor. Endoscopic ultrasound (EUS) is considered the best imaging modality to detect small pancreatic tumors. However, little is known about how small pancreatic neuroendocrine tumors (pNETs) present on EUS. PATIENTS AND METHODS: In this multicenter study, we retrospectively analyzed the endosonographic characteristics of small pNETs which had been detected due to typical biochemistry and clinical symptoms or during surveillance of MEN 1...

A man in his 60s was referred to our institution for the evaluation of a gastric neuroendocrine tumor (G-NET) located in the fornix and that measured 13mm in size. Blood test results revealed hypergastrinemia (up to 3376pg/ml). Additional tests, including esophagogastroduodenoscopy, computed tomography, and intragastric pH monitoring, indicated that hypergastrinemia was not associated with type A autoimmune gastritis or gastrinoma. The patient was positive for the immunoglobulin G antibody against Helicobacter pylori, suggesting type B chronic atrophic gastritis as the cause for the condition...

We report a case of developing multiple adenocarcinoma foci in multiple hyperplastic polyps in a patient with Helicobacter pylori infection and hypergastrinemia during long-term proton pump inhibitor (PPI) therapy. A 57-year-old man, who was undergoing hemodialysis for chronic renal failure, underwent an upper gastrointestinal endoscopy to elucidate the cause of anemia. Atrophic gastritis with H. pylori infection and multiple adenocarcinoma foci in multiple hyperplastic polyps were found in the endoscopic and histological examinations...

A 51-year-old woman complaining of weakness in the limbs was diagnosed as having a duodenal gastrinoma on performing a further evaluation. Surgical resection was performed with selective arterial calcium injection for localization. During preoperative hospitalization, she experienced recurrent severe vomiting and diarrhea after endoscopy, leading to acute kidney injury. To our knowledge, this is the first report of gastrinoma with post-endoscopy symptom exacerbation. Although the etiology is unknown, the findings in this case suggest that sufficient fluid replacement, sedation, and high-dose proton pump inhibitor administration should be taken into consideration when performing endoscopy in gastrinoma patients...

Zollinger-Ellison syndrome (ZES) is caused by hypersecretion of gastrin from duodenal or pancreatic gastrinomas. We report a case of a 57-year-old female who presented with chronic diarrhea. CT abdomen showed multiple liver masses. Liver biopsy suggested metastatic well-differentiated neuroendocrine tumor. Serum gastrin level was markedly elevated. MRI abdomen, somatostatin receptor scintigraphy and endoscopic ultrasound failed to reveal primary site of the tumor. Upper gastrointestinal endoscopy showed hyperplastic gastric folds and multiple duodenal ulcers consistent with ZES...

BACKGROUND: Zollinger-Ellison syndrome is a rare cause of tumoral hypergastrinemia; 1 of 5 patients with this syndrome also has multiple endocrine neoplasia type 1. The diagnosis of this disease is complicated by the widespread use of proton pump inhibitors that can elevate serum gastrin levels, the cornerstone for biochemical diagnosis. Abrupt discontinuation of proton pump inhibitors could lead to adverse outcomes. Clinician awareness of the relationship between Zollinger-Ellison syndrome and multiple endocrine neoplasia type 1 could lead to a safer diagnostic pathway...

OBJECTIVE: To study subtype classification of gastric neuroendocrine neoplasm (NEN) and their clinicopathological characteristics in order to provide reference for clinical practice. METHODS: Clinicopathological data of 241 gastric NEN patients (174 cases from China-Japan Friendship Hospital and 67 cases from The First Affiliated Hospital of Sun Yat-Sen University) between January 2011 and June 2016 were retrospectively summarized. According to serum gastrin, 24-hour intragastric pH monitoring and pathological grade, patients with gastric NEN were divided into 4 types: type I( (hypergastrinemia and achlorhydria, related to autoimmune chronic atrophic gastritis), type II( [hypergastrinemia and Zollinger-Ellison syndrome, related to gastrinoma or multiple endocrine neoplasia type I( (MEN-I()], type III( (sporadic disease with normal serum gastrin level), and type IIII( [poorly differentiated gastric neuroendocrine carcinoma (NEC) and mixed adenoneuroendocrine carcinoma (MANEC)]...

BACKGROUND: Distal pancreatectomy is the most frequent operation for insulinomas complicating multiple endocrine neoplasia type 1 insulinoma, although there are conditions for which a different operative approach might be preferable. In this article, we report the operative experience of a referral center for multiple endocrine neoplasia type 1 insulinoma. METHODS: Twelve patients underwent operations between 1992 and 2015: 8 underwent a distal pancreatic resection, and 4 underwent a pancreatoduodenectomy...

Multiple Endocrine Neoplasia (MEN) is a condition in which several endocrine organs of an individual are affected by adenoma, hyperplasia and less often carcinoma, either simultaneously or at different stages of life. Two existing syndromes, MEN1 and MEN2 (2A, 2B), in literature is also mentioned MEN4, are associated also with other non-endocrine disorders. MEN1 (Wermer syndrome) affects the pituitary, parathyroid, and pancreatic area. 95 % of patients show very early manifestation of hyperparathyroidism, often before 40 years of age...
