Renal cell carcinoma metastases to pancreas, thyroid, and contralateral adrenal gland are decidedly uncommon. Clear cell renal cell carcinoma (CCRCC) is the most frequent subtype. Cytology diagnosis may be challenging. A 74-year-old male with remote history of vocal cord malignancy and hypertension presented with abdominal pain. Computed tomography (CT) revealed 8.4 cm left renal mass highly suspicious for renal cell carcinoma, a 1.8 cm mass within vessels near left adrenal and a 2.5 cm mass in pancreatic tail...

BACKGROUND: Neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and lymphocyte-monocyte ratio (LMR) may serve as a simple index of the immune function. The aim of this study was to investigate the prognostic significance of NLR, PLR, and LMR in patients with resectable pancreatic ductal adenocarcinoma (PDAC) and to verify whether such biomarkers are associated with changes in populations of lymphoid cells. METHODS: The prognostic implications of blood count parameters were evaluated in a retrospective cohort of 442 subjects undergoing pancreatic resections for PDAC...

PURPOSE: Current strategies for managing neuroendocrine tumors (NETs) in adult patients are reviewed, with a focus on medication safety concerns. SUMMARY: NETs usually originate in the gastrointestinal or bronchopulmonary tract. Symptoms due to hormonal hypersecretion often occur in patients with foregut or midgut NETs or liver metastases. Surgical resection is recommended for most localized NETs, while systemic cytotoxic chemotherapy is typically used for high-grade and pancreatic tumors...

: The complex network of biochemical and biophysical cues in the pancreatic desmoplasia not only presents challenges to the fundamental understanding of tumor progression, but also hinders the development of therapeutic strategies against pancreatic cancer. Residing in the desmoplasia, pancreatic stellate cells (PSCs) are the major stromal cells affecting the growth and metastasis of pancreatic cancer cells by means of paracrine effects and extracellular matrix protein deposition. PSCs remain in a quiescent/dormant state until they are 'activated' by various environmental cues...

BACKGROUND & AIMS: Cigarette smoke has been identified as an independent risk factor for chronic pancreatitis (CP). Little is known about the mechanisms by which smoking promotes development of CP. We assessed the effects of aryl hydrocarbon receptor (AhR) ligands found in cigarette smoke on immune cell activation in humans and pancreatic fibrosis in animal models of CP. METHODS: We obtained serum samples from patients with CP treated at Stanford University hospital and healthy individuals (controls) and isolated CD4+ T cells; levels of interleukin-22 (IL22) were measured by ELISA and smoking histories were collected...

BACKGROUND & AIMS: Vitamin D (Vit D) deficiency in cystic fibrosis (CF) is partially secondary to exocrine pancreatic insufficiency. Our aim was to establish a Vit D3 supplementation protocol that will increase 25(OH)D to the recommended level (30 ng/mL). METHODS: Retrospective study of 200 patients (≥18 years) conducted from February 2007 to June 2014 at the CF clinic of the Centre Hospitalier de l'Université de Montréal. Vit D3 supplementation protocol was 1600 IU/day or 10,000 IU/week during the summer (May 1st to October 31st) and 3200 IU/day or 20,000 IU/week during the winter (November 1st to April 30th), in addition to the 1200 IU/day included in multivitamins...

The aim of our study was to develop ursolic acid (UA) prodrugs in order to overcome UA's weakness, which has an extremely low bioavailability. UA-medoxomil (NX-201), one of our UA prodrugs, showed an improved bioavailability about 200times better than UA in rodent model. According to in vivo test performed with PANC-1 xenograft SCID mouse model, tumor growth rate decreased dose-dependently and 100mg/kg dose of NX-201 had an anticancer effect comparable to gemcitabine. Most of all the combination of NX-201 (50mg/kg, po, daily) and gemcitabine (40mg/kg, iv, 2timesperweek) even reduced tumor size after three weeks...

BACKGROUND: The phase 3 MPACT trial in patients with metastatic pancreatic cancer demonstrated superior efficacy of nab-paclitaxel (nab-P) + gemcitabine (Gem) vs Gem monotherapy for all endpoints examined including overall survival, the primary endpoint. In the MPACT trial, patients were treated until progressive disease (PD) or unacceptable toxicity. The current exploratory analysis investigated outcomes of patients from the MPACT trial who were treated until PD, in order to understand how to maximize treatment benefit from nab-P + Gem...

High-resolution imaging methods (HRIMs) and biomarkers present the second step of pancreatic cancer (PC) diagnostics in at-risk individuals. These include patients with positive risk factors, early symptoms, nonresponders to the initial antidiabetic therapy, patients older than 50 years of age with new-onset unstable diabetes requiring insulin as well as patients with long-term insulin-non-dependent diabetes and recent (up to 6 months) failure of antidiabetic therapy. The procedures should be started without delay and the co-operation between the primary and tertiary medical centers is highly desirable...

Amplification or overexpression of MYCN is involved in development and maintenance of multiple malignancies. A subset of these tumors originates from neural precursors, including the most aggressive forms of the childhood tumors, neuroblastoma and medulloblastoma. In order to model the spectrum of MYCN-driven neoplasms in mice, we transgenically overexpressed MYCN under the control of the human GFAP-promoter that, among other targets, drives expression in neural progenitor cells. However, LSL-MYCN;hGFAP-Cre double transgenic mice did neither develop neural crest tumors nor tumors of the central nervous system, but presented with neuroendocrine tumors of the pancreas and, less frequently, the pituitary gland...

OBJECTIVE: To examine whether pancreaticogastrostomy (PG) or pancreaticojejunostomy (PJ) is the best reconstruction method to reduce occurrence of postoperative complications, especially pancreatic fistula (PF), after pancreaticoduodenectomy (PD). BACKGROUND: PF is one of the most severe complications after PD. The best reconstruction method to reduce occurrence of PF is controversial. Therefore, we carried out this meta-analysis to compare PG with PJ. METHODS: A systematic review was conducted in PubMed, EMBASE, and Cochrane Library to identify studies comparing PG with PJ, published up to October 2015...

Translation of mRNA in alternate reading frames (ARF) is a naturally occurring process heretofore underappreciated as a generator of protein diversity. The MUC1 gene encodes MUC1-TM, a signal-transducing trans-membrane protein highly expressed in human malignancies. Here we show that an AUG codon downstream to the MUC1-TM initiation codon initiates an alternate reading frame thereby generating a novel protein, MUC1-ARF. MUC1-ARF, like its MUC1-TM 'parent' protein, contains a tandem repeat (VNTR) domain. However, the amino acid sequence of the MUC1-ARF tandem repeat as well as N- and C- sequences flanking it differ entirely from those of MUC1-TM...

Importance: Outcomes for patients with pancreatic ductal adenocarcinoma (PDAC) remain poor. Advances in next-generation sequencing provide a route to therapeutic approaches, and integrating DNA and RNA analysis with clinicopathologic data may be a crucial step toward personalized treatment strategies for this disease. Objective: To classify PDAC according to distinct mutational processes, and explore their clinical significance. Design, Setting, and Participants: We performed a retrospective cohort study of resected PDAC, using cases collected between 2008 and 2015 as part of the International Cancer Genome Consortium...

BACKGROUND: Destruction of the insulin-producing beta cells in type 1 diabetes (T1D) is induced by invasion of immune cells causing pancreatic inflammation. Cannabidiol (CBD), a phytocannabinoid, derived from the plant, Cannabis sativa, was shown to lower the incidence of diabetes in non-obese diabetic (NOD) mice, an animal model of spontaneous T1D development. OBJECTIVE: The goal of this study was to investigate the impact of experimental CBD treatment on early pancreatic inflammation in T1D by intravital microscopy (IVM) in NOD mice...

Regenerating genes (Reg) have been found during the search for factors involved in pancreatic islet regeneration. Our recent study discovered that pancreatic β-cell-specific overexpression of Reg3β protects against streptozotocin (Stz) -induced diabetes in mice. To investigate its potential roles in the treatment of diabetes, we produced a recombinant Reg3β protein and provided evidence that it is active in promoting islet β-cell survival against Stz- triggered cell death. Though ineffective in alleviating preexisting diabetes, pretreatment of recombinant Reg3β was capable of minimizing the Stz-induced hyperglycemia and weight loss, by preserving serum and pancreatic insulin levels, and islet β-cell mass...
