OBJECTIVES: Emerging data suggest that not all grade 3 (G3) pancreatic neuroendocrine neoplasms (panNENs) behave the same; tumor differentiation may predict outcome. METHODS: Patients with G3 panNENs treated at our institution between 1999 and 2014 were identified. Demographics, response to therapy, and overall survival were determined. RESULTS: Forty-five patients were identified, 16 with G3 well differentiated pancreatic neuroendocrine tumors (WD-panNETs) and 29 with poorly differentiated neuroendocrine carcinomas (PDNEC)...

OBJECTIVE: The aim of this study was to assess health care utilization and costs related to acute pancreatitis (AP) in patients with severe hypertriglyceridemia (sHTG) levels. METHODS: Patients with sHTG levels 1000 mg/dL or higher were identified from January 1, 2007, to June 30, 2013. The first identified incident triglyceride level was labeled as index date. All-cause, AP-related health care visits, and mean total all-cause costs in patients with and without AP were compared during 12 months postindex...

OBJECTIVES: The study aimed to explore the alteration of autophagy in rat pancreas treated with exenatide. METHODS: Normal Sprague-Dawley rats and diabetes-model rats induced by 2-month high-sugar and high-fat diet and streptozotocin injection were subcutaneously injected with exenatide, respectively, for 10 weeks, with homologous rats treated with saline as control. Meanwhile, AR42J cells, pancreatic acinar cell line, were cultured with exenatide at doses of 5 pM for 3 days...

OBJECTIVES: In this study, we screened for differentially expressed genes in acute pancreatitis and the herbal monomers that regulate these genes. METHODS: Gene expression profile data were downloaded from the Gene Expression Omnibus database (GSE3644). We used the Human Protein Reference Database to determine the protein-protein interaction network and CFinder software (Department of Biological Physics of Eötvös University, Budapest, Hungary) to identify several functional modules...

OBJECTIVE: Members of the transient receptor potential (TRP) channels are involved in mediating the electrical excitability and stimulus-secretion coupling in the pancreatic β-cells. The expression and the relative abundance of different TRP channels in the human β-cells are unknown. The objective of this study was to examine the expression of the TRP channels and their relative abundance in the human β-cell. METHODS: RNA sequencing data obtained from human islets, fluorescence-activated cell sorting-purified human β-cell and human pancreatic acinar cells were analyzed...

OBJECTIVES: There is a need for validated predictive markers of gemcitabine response to guide precision medicine treatment in pancreatic cancer. We previously validated human equilibrative nucleoside transporter 1 as a predictive marker of gemcitabine treatment response using Radiation Therapy Oncology Group 9704. Controversy exists about the predictive value of gemcitabine metabolism pathway biomarkers: deoxycytidine kinase (DCK), ribonucleotide reductase 1 (RRM1), RRM2, and p53R2. METHODS: Radiation Therapy Oncology Group 9704 prospectively randomized 538 patients after pancreatic resection to receive either 5-fluorouracil or gemcitabine...

A workshop was sponsored by the National Institute of Diabetes and Digestive and Kidney Diseases to focus on research gaps and opportunities in chronic pancreatitis (CP) and its sequelae. This conference marked the 20th year anniversary of the discovery of the cationic trypsinogen (PRSS1) gene mutation for hereditary pancreatitis. The event was held on July 27, 2016, and structured into 4 sessions: (1) pathophysiology, (2) exocrine complications, (3) endocrine complications, and (4) pain. The current state of knowledge was reviewed; many knowledge gaps and research needs were identified that require further investigation...

OBJECTIVE: Somatostatin receptors (SSTRs), products of gene superfamily SSTR1-5, are commonly expressed in neuroendocrine tumors (NETs). Somatostatin analogs (SSAs) bind to SSTRs and are used as therapeutic agents in patients with advanced NETs. We hypothesized that tumor SSTR expression status would be associated with clinical outcomes in NET. METHODS: Expression of the 5 SSTRs was evaluated by immunohistochemistry, using tissue microarrays comprising 173 primary NETs, 24 matched metastases, and 22 metastatic NETs from 195 patients...

OBJECTIVES: Increased production and processing (degradation) of hyaluronan (HA) is critical for cancer invasion and metastasis. Although HA is known to be overexpressed in pancreatic ductal adenocarcinoma (PDAC), little is known about the expression and biological significance of HA-degrading enzymes, hyaluronidases (HYALs), in PDAC. METHODS: Expression of HYALs mRNA was examined in PDAC cells by quantitative real-time RT-PCR. HYAL1 protein expression was examined in primary PDAC tumors by enzyme-linked immuno-sorbent assay...

OBJECTIVES: Despite decades of effort, the 5-year overall survival rate of pancreatic cancer (PC) remains at only approximately 5%. Until now, no detailed knowledge regarding the worldwide research architecture of PC has yet been established. METHODS: Hence, we conducted this scientometric analysis to quantify the global research activity in this field. The total research productivity was screened and research output of countries, categories, individual institutions, authors, and their collaborative networks were analyzed by the new quality and quantity indices in science platform...

OBJECTIVES: Postoperative pancreatic fistula (POPF) is a life-threatening complication after pancreaticoduodenectomy (PD). The aim of this study is to evaluate the significance of pancreatic amylase level of pancreatic juice for PF after PD. METHODS: The subjects were 46 patients who underwent PD between January 2012 and August 2015 at Jikei University Hospital. We retrospectively investigated the relation between patient characteristics including pancreatic amylase level of pancreatic juice through the pancreatic drainage tube and the incidence of POPF (grade B or grade C according to the International Study Group on the Pancreatic Fistula) using univariate and multivariate analyses...

OBJECTIVE: To study if chronic pancreatitis (CP) is a risk factor for pancreatic cancer. METHODS: Through a cohort and a case-control study design, CP and other important risk factors including smoking, diabetes, alcohol, obesity, and genetic mutations were studied for their association with pancreatic cancer. RESULTS: In the cohort study, 402 patients with CP were included. During 3967.74 person-years of exposure, 5 of the 402 patients (4 idiopathic CP, 1 hereditary CP) developed pancreatic cancer after 16...

OBJECTIVES: The objective of this study was to study the role of hydrogen-rich saline (HRS) on acute hepatic injury (AHI) in acute necrotizing pancreatitis (ANP). METHODS: Rats were used for this study and an ANP model was induced by injecting 5% sodium taurocholate into the biliary-pancreatic duct. Experiments were performed in 3 groups: sham, ANP, and ANP + HRS (HRS). Animals were killed at 3, 12, and 24 hours after operation, and then blood and tissue samples were harvested...

OBJECTIVES: This study aimed to evaluate the influence of fungal infection and antifungal treatment on outcome in patients with walled-off pancreatic necrosis (WON). METHODS: A retrospective description of fungal infections in a cohort of consecutive patients undergoing endoscopic, transmural drainage and necrosectomy for WON, treated in a tertiary referral center was reviewed. RESULTS: Between 2005 and 2013, fungal infection in WON was documented in 57 (46%) of 123 patients...

OBJECTIVES: To improve the detection of pancreatic cancer (PC), a robust diagnostic biomarker is essential. We have previously discovered 4 serum metabolites (PC-594, lysophosphatidylcholine, phosphatidylcholine, and sphingomyelin) in distinguishing patients with PC from healthy controls. Here, we report the results of our validation phase by using larger numbers of independent and blinded samples. METHODS: We collected 3 mL of serum from 116 patients with PC and 138 healthy controls...
