The surgical management of duodenal pathology is challenging because of its retroperitoneal position and shared blood supply with the pancreas. We present three types of limited resection of the duodenum for the removal of superficial or small nonampullary duodenal (NADL) lesions, and also a review of the English literature regarding management, such as endoscopic resection and limited duodenal resection. Ten cases underwent limited resections of the duodenum for superficial or small NADL lesions from 2011 to 2015...

Insulinoma is a rare, usually benign, pancreatic neuroendocrine tumor. The clinical features of an insulinoma are fasting hypoglycemia with neuroglycopenic symptoms including confusion and unusual behavior, while hypertension is usually not associated with the disease. We herein report a patient with insulinoma who manifested paroxysmal hypertension and neuroglycopenic symptoms. The possible etiology of hypertension induced by an insulinoma is catecholamine release in response to hypoglycemia, which may cause acute hypertension through activation of the sympatho-adrenal system...

Neuroendocrine tumors (NETs) comprise a heterogeneous group of malignancies that express neuropeptides as synaptophysin, chromogranin A (CgA), and specific neuronal enolase (NSE), among others. Vasopressin (AVP) is a neuropeptide with an endocrine, paracrine, and autocrine effect in normal and pathological tissues. AVP receptors are present in human lung, breast, pancreatic, colorectal, and gastrointestinal tumors. While AVP V1 receptors are associated with stimulation of cellular proliferation, AVP V2 receptor (V2r) is related to antiproliferative effects...

Multiple endocrine neoplasia type 1 (MEN1) is an inherited predisposition to tumors of the parathyroid glands, anterior pituitary, and pancreatic islet cells. In this review, we discuss the clinical case of a 45-year-old woman with MEN1 that was presented at the 2015 North American Neuroendocrine Tumor Society Symposium. In our review of this patient's complicated clinical course and subsequent operative management, we highlight controversies in the diagnosis and management of pancreatic neuroendocrine tumors in MEN1...

Neuroendocrine tumors (NETs) metastasize to the skeleton in approximately 20% of patients. We have previously shown that the epithelial-mesenchymal transition (EMT) regulates the NET osteotropism and that CXCR4 overexpression predicts bone spreading. Here, we unravel the molecular mechanisms linking the activation of the CXCL12/CXCR4 axis to the bone colonization of NETs using cell lines representative of pancreatic (BON1, CM, QGP1), intestinal (CNDT 2.5), and bronchial origin (H727). By combining flow cytometry and ELISA, BON1, CM and QGP1 cells were defined as CXCR4high/CXCL12low, while H727 and CNDT 2...

: Doublecortin-like kinase 1 (DCLK1), a marker for intestinal and pancreatic cancer stem cells, is highly expressed in neuroblastomas. This study was conducted to assess DCLK1 expression levels in pancreatic neuroendocrine tumor (PNET) tissues and to explore the roles of this molecule in clinical tissue from multiple PNET patients, cells (BON1, QGP1, and CM), and tumor xenografts. Immunohistochemically, all PNET tissues highly and diffusely expressed DCLK1 as a full-length isoform, identical to that detected in primary liver NETs...

: Mutations affecting the mechanistic target of rapamycin (MTOR) signalling pathway are frequent in human cancer and have been identified in up to 15% of pancreatic neuroendocrine tumours (NETs). Grade A evidence supports the efficacy of MTOR inhibition with everolimus in pancreatic NETs. Although a significant proportion of patients experience disease stabilization, only a minority will show objective tumour responses. It has been proposed that genomic mutations resulting in activation of MTOR signalling could be used to predict sensitivity to everolimus...

RATIONALE: Pancreatic neuroendocrine tumors (pNET) are rare slowly growing tumors with a high metastatic potential. Peptide receptor radionuclide therapy (PRRT) with radiolabeled analogues has been developed as a new tool for the management of metastatic well-differentiated (grade 1 and 2) neuroendocrine tumors expressing somatostatin receptor (SSTR2). Chemotherapy is the mainstay in the management of grade 3 (G3) unresectable pancreatic neuroendocrine carcinoma (pNEC). To date, no study has evaluated the efficacy of PRRT in such tumors...

Sundeep Lakhtakia, Dong-Wan Seo
Real-time guidance of needle advancement has transformed Endoscopic Ultrasound from a diagnostic to an interventional procedure. EUS guided fine needle puncture has application in various interventional procedures (drainage of pseudocyst, biliary intervention, and injection of drugs). Celiac plexus or ganglion neurolysis for pain control is the major current EUS-guided fine-needle injection procedure. Feasibility and safety to accurately position needle devices and/or inject under real time EUS imaging with precise delivery of interventional agent have expanded the use of EUS to ablate tumor...

OBJECTIVE: The availability of new imaging techniques has conditioned an increase in the incidental diagnosis of small nonfunctioning pancreatic neuroendocrine tumors (PNET-NF). The best treatment is controversial, some authors advise a conservative approach in selected cases. Our aim is to analyze the evolution of incidental, small size PNET-NF, treated with clinical follow-up without surgery. METHODS: We performed a retrospective analysis of a prospective database of patients diagnosed incidentally with PNET-NF since November 2007 to September 2015...

Whole slide imaging (WSI) offers a convenient, tractable platform for measuring features of routine and special-stain histology or in immunohistochemistry staining by using digital image analysis (IA). We now routinely use IA for quantitative and qualitative analysis of theranostic markers such as human epidermal growth factor 2 (HER2/neu), estrogen and progesterone receptors, and Ki-67. Quantitative IA requires extensive validation, however, and may not always be the best approach, with pancreatic neuroendocrine tumors being one example in which a semiautomated approach may be preferable for patient care...

Esther Una Cidon
Neuroendocrine (NE) gastroenteropancreatic tumors are a heterogeneous group of neoplasias arising from neuroendocrine cells of the embryological gut. Their incidence have increased significantly over the past 3 decades probably due to the improvements in imaging and diagnosis. The recent advances in molecular biology have translated into an expansion of therapeutic approaches to these patients. Somatostatin analogs, which initially were approved for control of hormonal syndromes, have recently been proven to inhibit tumor growth...

BACKGROUND: The treatment of non-functioning pancreatic neuroendocrine tumors (NF-PNETs) still remains controversial. It is uncertain whether asymptomatic patients have better prognosis than symptomatic patients and whether surgery is necessary for asymptomatic patients. METHODS: Patients with NF-PNETs who were managed surgically or by surveillance between June 2007 and December 2013 were retrospectively studied. The choice of surgery or surveillance was based entirely on the patient's desire...

A woman in her 60s visited our hospital because of frequent hypoglycemia and episodes of unconsciousness over the last 6 years. A 4 cm tumor was detected on the pancreatic tail using abdominal computed tomography and ultrasonography. An insulinoma was strongly suspected from the results of the fasting test and glucagon load test, and a distal pancreatectomy with splenectomy was performed. Pathological examination indicated an insulinoma and neuroendocrine tumor(NET)G2 based on the WHO 2010 classification. The patient's blood sugar and insulin levels returned to normal, and hypoglycemic attacks disappeared postoperatively...

BACKGROUND: Laparoscopic organ-sparing pancreatectomy (LOSP) is an ideal therapeutic option in selected cases of pancreatic neuroendocrine tumors (PNETs). Nevertheless, given the low frequency of PNETs, there is scarce evidence regarding short and particularly long-term outcomes of LOSP in this clinical setting. METHODS: All patients with PNETs who underwent surgery (under a LOSP policy) were retrospectively reviewed from a prospective database maintained at our center...
