Exocrine pancreatic insufficiency (EPI) is characterized by a deficiency of exocrine pancreatic enzymes, resulting in deficits in digestion of all macronutrients, with deficiencies in digestion of fats being the most clinically relevant. The leading cause of EPI is chronic pancreatitis. However, many other causes and conditions may be implicated, including cystic fibrosis, pancreatic duct obstruction, gastric and pancreatic surgery, diabetes mellitus and other conditions. Physical and biochemical causes of EPI include decreased production and secretion of lipase, increased lipase destruction, pancreatic duct obstruction, decreased lipase stimulation and degradation, as well as gastrointestinal motility disorders...

INTRODUCTION: Pancreatic adenocarcinoma carries a grim prognosis. In 2007, gemcitabine with erlotinib emerged as an appropriate treatment option for patients with advanced inoperable or metastatic disease (APC). In this phase II trial we sought to evaluate the efficacy of erlotinib monotherapy in patients with APC who had disease refractory to or ineligibility for gemcitabine-based therapy. METHODS: Eligible patients who had received 0 or 1 non-EGFR inhibitor containing gemcitabine-based chemotherapy for APC were recruited prospectively and treated with erlotinib 150 mg orally daily until unacceptable toxicity or disease progression...

BACKGROUND: Arsenic is known as an endocrine disruptor that people are exposed to through various sources such as drinking water and indigestion of marine products. Although some epidemiological and animal studies have reported a correlation between arsenic exposure and diabetes development, there are limited studies regarding the toxic effects of organic arsenic including arsenobetaine on the human body. Here, we analyzed the association between urine arsenobetaine and the homeostasis model assessment of β-cell function (HOMA-β), which is an index for predicting diabetes development and reflecting the function of pancreatic β-cells...

PURPOSE OF REVIEW: This report reviews recent aspects of pancreatitis immunology and environmental factors that link to development and progression of disease. RECENT FINDINGS: Limited human and animal model studies have recently attempted to understand immune mechanisms that lead to the pathogenesis of acute and chronic pancreatitis. Based on these studies innate immune responses emerge as critical elements in disease pathogenesis and severity of inflammation. The immune basis for environmental factors such as smoking, which are highly associated with disease progression highlight novel cross talk mechanisms between immune and nonimmune pancreatic cells such as the pancreatic stellate cells...

BACKGROUND: Although the relationship between non-O blood types and the risk of exocrine pancreatic cancer has been demonstrated, the association between ABO blood types and sporadic pancreatic neuroendocrine tumor (PNET) has not been reported thus far. METHODS: This hospital-based, case-control study included 387 patients with PNET and 542 age- and sex-matched controls. Unconditional multivariable logistic regression analysis was performed to estimate the adjusted odds ratios (AORs) and 95% confidence intervals (CIs)...

Aims: Oxidative stress may contribute to the development of chronic pancreatitis (CP). The enzymes manganese superoxide dismutase 2 (MnSOD, SOD2) and catalase (CAT) counteract free radical activity within the mitochondria and the cytosol. Moreover, CAT activity contributes to the transformation of ethanol to acetaldehyde, a toxic intermediate product of ethanol metabolism, which has been associated with pancreatic damage. Common functional polymorphisms have been described in the MnSOD gene [rs4880, NM_000636...

Because pancreatic cancer (PC) historically has had poor prognosis and five year survival rates, it has been intensely investigated. Analysis of PC incidence and biology has shown a link between different risk factors such as smoking, alcoholism, and obesity and disease progression. Important factors affecting PC include the epigenomic changes driven by DNA methylation and histone acetylation, and actions of microRNA inducing oncogenic or tumor suppressor effects. Studies have identified markers whose dysregulation seem to play important roles in PC progression...

Many cancers share specific genetic risk factors including both rare high-penetrance mutations and common single nucleotide polymorphisms (SNPs) identified through genome-wide association studies (GWAS). However, little is known about the overall shared heritability across cancers. Quantifying the extent to which two distinct cancers share genetic origin will give insights to shared biological mechanisms underlying cancer and inform design for future genetic association studies. In this study, we estimated the pair-wise genetic correlation between six cancer types (breast, colorectal, lung, ovarian, pancreatic and prostate) using cancer-specific GWAS summary statistics data based on 66,958 case and 70,665 control subjects of European ancestry...

Pancreatic carcinoma is an aggressive malignancy with particularly low 5-year survival rate. In order to improve the dismal survival rate, identification of new potential susceptibility risk factors for the prevention and early detection of pancreatic carcinoma is of utmost importance. Lysosomal protein transmembrane 4 beta has two alleles designated as LAPTM4B*1 and LAPTM4B*2. The aim of this study was to investigate the association between lysosomal protein transmembrane 4 beta gene polymorphism and the risk of pancreatic carcinoma in China...

Pancreatic neuroendocrine neoplasms (PNENs) represent 10% of all pancreatic tumors by prevalence. Their incidence has reportedly increased over recent decades in parallel with that of pancreatic adenocarcinoma. PNENs are relatively rare and of the few institutions that have published potential risk factors, findings have been heterogenous. AIM: To investigate the association between potential risk and protective factors for the occurrence of sporadic PNENs across a European population from several institutions...

BACKGROUND: Agricultural workers may be exposed to potential carcinogens including pesticides, sensitizing agents and solar radiation. Previous studies indicate increased risks of hematopoietic cancers and decreased risks at other sites, possibly due to differences in lifestyle or risk behaviours. We present findings from CanCHEC (Canadian Census Health and Environment Cohort), the largest national population-based cohort of agricultural workers. METHODS: Statistics Canada created the cohort using deterministic and probabilistic linkage of the 1991 Canadian Long Form Census to National Cancer Registry records for 1992-2010...

Pancreatic cancer is the fourth leading cause of cancer-associated mortality. The major risk factor for pancreatic cancer is cigarette smoking. Kras mutations are commonly observed in human pancreatic cancers. The present study examined the hypothesis that exposure to cigarette smoke and overexpression of a mutant Kras gene in the pancreas affects pancreatic cell proliferation in mice. Mice overexpressing the mutant Kras gene (KRas(G12D)) in the pancreas as well as wild-type mice were exposed to environmental tobacco smoke for 2 weeks...
