  • Indications included 18 neuroendocrine tumors (11 nonfunctioning), 10 serous and 10 mucinous cystadenomas, 5 intraductal papillary mucinous neoplasms, 3 main pancreatic duct strictures, 2 solid cystic papillary tumors, 1 hydatid cyst, and 1 acinar cell carcinoma.
  • The proximal pancreatic remnant was suture ligated.
  • The distal pancreatic end was anastomosed to a Roux-en-Y jejunal loop (n = 6) or to the stomach (n = 44).
  • Three patients had associated procedures, 1 each for metastatic liver cytoreduction (VIPoma), hydatid liver disease, and pancreatic resection for multifocal mucinous cystadenoma.
  • The mean length of the resected pancreas was 45 mm (range, 20-80 mm) and the mean tumor size was 23 mm (5-60 mm).
  • Complications included the following: 4 patients (8%) had pancreatic anastomotic leak, 5 patients (10%) had acute pancreatitis, 7 patients (14%) had intra-abdominal collection, and 3 patients (6%) had bleeding.
  • No patients developed de novo diabetes.
  • The actuarial 5-year patient and pancreatic remnant survival rates were 98% and 95%, respectively.
  • In our series, central pancreatectomy led to effective preservation of both cephalic and distal pancreatic remnants without a significant increase in postoperative morbidity compared with conventional pancreatectomy.

  • [Title] Acinar cell carcinoma of the pancreas in a young patient with chronic pancreatitis.
  • BACKGROUND: Acinar cell carcinoma (ACC) is a rare malignancy of the pancreas arising from acinar cells.
  • Unlike ductal adenocarcinoma, this tumor rarely presents with pancreatitis.
  • METHODS: We present a case of ACC associated with chronic calcifying pancreatitis, and a review of the literature focusing on diagnosis and management.
  • CONCLUSIONS: The clinical presentation of ACC of the pancreas is not specific and the tumor can be under-diagnosed when associated with chronic pancreatitis.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Absence of a dilated duct predicts benign disease in suspected pancreas cancer: a simple clinical rule.
  • BACKGROUND: Pancreatic cancer can be difficult to diagnose.
  • METHODS: Patients presenting for endoscopic ultrasound (EUS) evaluation for suspected pancreatic mass were prospectively enrolled.
  • The characteristics of patients with cancer were compared to the characteristics of patients without cancer using Chi-square testing and t-tests.
  • Thirty-three patients had cancer and 40 had benign disease.
  • On multivariate analysis, only vascular or organ invasion and dilation of the pancreatic duct (PD) were significantly associated with cancer.
  • PD dilation was examined as a stand-alone feature.
  • CONCLUSIONS: The most significant negative predictive endosonographic finding in patients with suspected pancreatic cancer is a non-dilated PD.
  • If a patient with suspected pancreatic cancer does not have a dilated PD and the FNA is negative for malignancy, the likelihood of cancer is low.

  • [Title] [Pathogenesis of endocrine tumors of the pancreas].
  • Precise pathohistologic and immunohistochemical investigations of the pancreas in elderly autopsy cases revealed that endocrine tumors are found very frequently.
  • Some endocrine tumors of the pancreas may originate from Langerhans islets, although other endocrine tumors may develop from endocrine cells or stem cells with multiple differentiation ability and occur in the duct cells or acinar cells.
  • This possibility may be supported by the evidence that ductular or tubular structures were found in or adjacent to tumors in about 60% of minute tumors and that hormone production was found in both duct cells and acinar cells based on immunohistochemical findings.
  • The occurrence of ductuloinsular tumors, acinar endocrine cell tumors, and duct-acinar-islet cell tumors may also support these observations.
  • Molecular biological investigations will further analyze the pathogenesis of endocrine tumors of the pancreas.
  • There are three possible origins of endocrine tumors of the pancreas: Langerhans islets cells, ductular cells, and acinar cells.

  • [Title] Cytology of pancreatic acinar cell carcinoma.
  • Acinar cell carcinoma (ACC) of the pancreas is extremely uncommon and its cytologic features have rarely been described.
  • We describe the cytologic features of cases we have seen, review the literature regarding its cytologic features and discuss the pitfalls that may be encountered and the use of immunohistochemistry for its diagnosis.
  • We searched our databases for all cases of histologically confirmed pancreatic ACC which had undergone prior fine needle aspiration (FNA) of the primary pancreatic lesion.
  • Four cases of pancreatic ACC were found that had undergone FNA prior to histologic confirmation of the diagnoses.
  • All masses were in the head of the pancreas, 2 had apparent peri-pancreatic adenopathy and 1 had an apparent liver metastasis.
  • Original cytologic diagnoses included "acinar cell carcinoma," "pancreatic endocrine tumor," "favor neuroendocrine tumor, low-grade" and "non-diagnostic specimen."
  • The cytologic features included small to moderate-sized loose groups with numerous single cells, prominent acinar formation, little anisonucleosis and prominent nucleoli.
  • The cytologic features showed significant overlap with those of pancreatic endocrine tumors.

  • [Title] Spontaneous induction of murine pancreatic intraepithelial neoplasia (mPanIN) by acinar cell targeting of oncogenic Kras in adult mice.
  • Pancreatic ductal adenocarcinoma (PDAC) is believed to arise through a multistep model comprised of putative precursor lesions known as pancreatic intraepithelial neoplasia (PanIN).
  • The most faithful genetic models activate an oncogenic Kras(G12D) knockin allele within the pdx1- or ptf1a/p48-expression domain of the entire pancreatic anlage during development, thus obscuring the putative cell(s)-of-origin from which subsequent mPanIN lesions arise.
  • In our study, activation of this knockin Kras(G12D) allele in the Elastase- and Mist1-expressing mature acinar compartment of adult mice resulted in the spontaneous induction of mPanIN lesions of all histological grades, although invasive carcinomas per se were not seen.
  • We observed no requirement for concomitant chronic exocrine injury in the induction of mPanIN lesions from the mature acinar cell compartment.
  • The acinar cell derivation of the mPanINs was established through lineage tracing in reporter mice, and by microdissection of lesional tissue demonstrating Cre-mediated recombination events.
  • In contrast to the uniformly penetrant mPanIN phenotype observed following developmental activation of Kras(G12D) in the Pdx1-expressing progenitor cells, the Pdx1-expressing population in the mature pancreas (predominantly islet beta cells) appears to be relatively resistant to the effects of oncogenic Kras.
  • We conclude that in the appropriate genetic context, the differentiated acinar cell compartment in adult mice retains its susceptibility for spontaneous transformation into mPanIN lesions, a finding with potential relevance vis-à-vis the origins of PDAC.

  • [Title] Pancreatic acinar tissue in liver explants: a morphologic and immunohistochemical study.
  • BACKGROUND: Pancreatic acini-like tissue is occasionally seen in the liver.
  • To gain further insight into this issue, we performed a pathologic and immunohistochemical study in liver explants to identify pancreatic acinar tissue.
  • Formalin-fixed, paraffin-embedded tissues were stained with hematoxylin-eosin, and immunohistochemical analyses using antibodies against CK7, CK8, and CK19 (biliary type cytokeratins), CD56 (positive in reactive bile ductules), chromogranin A (positive in reactive bile ductules and human oval-like/hepatic progenitor cells), pancreatic amylase, and PDX-1 were performed.
  • The immunohistochemical comparison group consisted of 3 gastric biopsies diagnosed as autoimmune gastritis with pancreatic metaplasia and 3 normal pancreatic tissues from pancreatectomy specimens.
  • RESULTS: Sixteen (4.2%) of 382 liver explants contained pancreatic acini-like tissue.
  • Fifteen of these were cirrhotic livers due to cryptogenic cirrhosis (n=1), primary biliary cirrhosis (n=3), primary sclerosing cholangitis (n=1), chronic hepatitis C-related cirrhosis (n=5), and cirrhosis with hepatitis C and hepatocellular carcinoma (n=5).
  • The pancreatic acini-like tissue appeared as small clusters of compactly packed cells that either blended imperceptibly with or were in close proximity to adjacent bile ducts or ductules.
  • The pancreatic acinar tissue was diffusely reactive for amylase, was occasionally positive for keratin 8 and chromogranin A, and was negative for CD56, keratin 7, and keratin 19.
  • CONCLUSIONS: Our results collectively indicate that pancreatic acini-like tissue in liver represent aggregates of pancreatic acinar cells admixed with small intra-acinar terminal ductules.
  • Given the close spatial relationship with reactive bile ductules and the apparent transition in immunophenotype from bile ductules to pancreatic acinar tissue, the latter is likely of metaplastic origin derived from a hepatic progenitor lineage.

  • [Title] Comparative proteomic analysis for the detection of biomarkers in pancreatic ductal adenocarcinomas.
  • AIMS: To search for novel potential protein biomarkers for the early detection and better intervention of pancreatic ductal adenocarcinoma (PDAC).
  • METHODS: Eight pairs of matched PDAC and non-cancerous pancreas tissues were profiled with two-dimensional electrophoresis; differentially expressed proteins were identified by mass spectrometry.
  • Immunohistochemistry showed that TBX4 expression could be seen in both centroacinar cells and small ducts in normal pancreas and tumour cells in 5/5 (100%) well differentiated, 35/38 (92.1%) moderately differentiated, and 11/18 (61.1%) poorly differentiated PDAC tissues with different staining intensity.
  • However, in normal acinar cells and tumour cells in the other 3/38 (7.9%) moderately differentiated and 7/18 (38.9%) poorly differentiated PDAC tissues, there was no visible TBX4 expression.
  • Strong expression of HSP60 could be seen in both acinar cells and small ducts in normal pancreas tissues and tumour cells in PDAC tissues except for islets and tumour stoma; no correlation was found between HSP60 expression and differentiation of PDAC tissues.

  • PNC-28 is a p53 peptide from its mdm-2-binding domain (residues 17-26), which contains the penetratin sequence enabling cell penetration on its carboxyl terminal end.
  • We have found that this peptide induces necrosis, but not apoptosis, of a variety of human tumor cell lines, including several with homozygous deletion of p53, and a ras-transformed rat acinar pancreatic carcinoma cell line, BMRPA1. Tuc3.

  • [Title] A case of acinar cell carcinoma of the pancreas that formed extensive tumor thrombus of the portal vein.
  • Abdominal ultrasonography and computed tomography revealed a large mass in the body and tail of the pancreas, which directly invaded the stomach and the spleen.
  • The specimens obtained from portal tumor thrombus were histologically compatible with acinar cell carcinoma.
  • Portal tumor thrombus is a rare condition in pancreatic tumors; however, it seems to be important to differentiate tumor thrombus from blood thrombus of the portal vein in order to know the true clinical stage and provide a suitable treatment.

  • [Title] Pancreas-specific protein disulfide isomerase has a cell type-specific expression in various mouse tissues and is absent in human pancreatic adenocarcinoma cells: implications for its functions.
  • However, the pancreas-specific PDI homolog was previously suggested to be exclusively expressed in the pancreas (thus commonly referred to as PDIp).
  • Notably, in the digestive organs, such as the stomach and pancreas, very high levels of PDIp were selectively expressed in the digestive enzyme-secreting cells (e.g., gastric chief cells and pancreatic acinar cells).
  • This observation suggests that PDIp may function as a protein-folding catalyst for secretory digestive enzymes.
  • In addition, high levels of PDIp expression were also detected in normal human pancreas, but its expression was mostly absent in human pancreatic duct adenocarcinoma and pancreatic cancer cell lines.
  • The absence of PDIp expression in pancreatic adenocarcinoma may serve as an additional biomarker for pancreatic cancer.

  • [Title] BGLAP is expressed in pancreatic cancer cells and increases their growth and invasion.
  • In this study, we analyzed the expression and role of BGLAP in the normal human pancreas, chronic pancreatitis (CP), and pancreatic ductal adenocarcinoma (PDAC) using quantitative RT-PCR, immunohistochemistry, immunocytochemistry and enzyme immunoassays, as well as cell proliferation and invasion assays.
  • RESULTS: Compared to the normal pancreas, BGLAP mRNA and protein levels were not significantly different in CP and PDAC tissues.
  • BGLAP was faintly present in the cytoplasm of normal acinar cells but was strongly expressed in the cytoplasm and nuclei of tubular complexes and PanIN lesions of CP and PDAC tissues.
  • Furthermore, BGLAP expression was found in the cancer cells in PDAC tissues as well as in 4 cultured pancreatic cancer cell lines.
  • TNFalpha reduced BGLAP mRNA and protein expression levels in pancreatic cancer cell lines.
  • In addition, BGLAP silencing led to reduction of both cell growth and invasion in those cells.
  • CONCLUSION: BGLAP is expressed in pancreatic cancer cells, where it potentially increases pancreatic cancer cell growth and invasion through autocrine and/or paracrine mechanisms.

  • [Title] A case of mistaken identity? Nonductal origins of pancreatic "ductal" cancers.
  • In this issue of Cancer Cell, Guerra and colleagues provide important new insights regarding the ability of specific pancreatic cell types to generate invasive pancreatic cancer.
  • First, they demonstrate that classical pancreatic "ductal" neoplasia can be induced by activation of oncogenic Kras in nonductal exocrine cells.
  • Second, they show that, while Kras activation in immature acinar and centroacinar cells is readily able to induce ductal neoplasia, Kras-mediated tumorigenesis in mature exocrine pancreas requires the induction of chronic epithelial injury.
  • The results shed new light on the "cell of origin" of pancreatic ductal cancer and demonstrate that chronic pancreatitis provides a permissive environment for Kras-induced pancreatic neoplasia.

  • [Title] Activation of PyMT in beta cells induces irreversible hyperplasia, but oncogene-dependent acinar cell carcinomas when activated in pancreatic progenitors.
  • It is unclear whether the cellular origin of various forms of pancreatic cancer involves transformation or transdifferentiation of different target cells or whether tumors arise from common precursors, with tumor types determined by the specific genetic alterations.
  • Previous studies suggested that pancreatic ductal carcinomas might be induced by polyoma middle T antigen (PyMT) expressed in non-ductal cells.
  • Induction of PyMT in beta cells causes beta-cell hyperplastic lesions that do not progress to malignant neoplasms.
  • When PyMT is de-induced, beta cell proliferation and growth cease; however, regression does not occur, suggesting that continued production of PyMT is not required to maintain the viable expanded beta cell population.
  • In contrast, induction of PyMT in early pancreatic progenitor cells under the control of Pdx1 produces acinar cell carcinomas and beta-cell hyperplasia.
  • The survival of acinar tumor cells is dependent on continued expression of PyMT.
  • Our findings indicate that PyMT can induce exocrine tumors from pancreatic progenitor cells, but cells in the beta cell lineage are not transdifferentiated toward exocrine cell types by PyMT; instead, they undergo oncogene-dependent hyperplastic growth, but do not require PyMT for survival.

  • [Title] Multiple endocrine neoplasia type 1 (MEN1): loss of one MEN1 allele in tumors and monohormonal endocrine cell clusters but not in islet hyperplasia of the pancreas.
  • CONTEXT: The occurrence of multiple small pancreatic endocrine tumors in patients suffering from multiple endocrine neoplasia type 1 (MEN1) represents a unique possibility to study early neoplasms and their potential precursor lesions.
  • To date, it is unknown whether small islet-like endocrine cell clusters found in MEN1 patients are neoplastic or rather hyperplastic.
  • DESIGN: We hypothesized that monohormonal endocrine cell clusters observed in MEN1 patients are small neoplasms with loss of heterozygosity of the MEN1 locus.
  • 2) monohormonal endocrine cell clusters;.
  • RESULTS: Loss of one MEN1 allele was found in all 27 microadenomas and 19 of 20 (95%) monohormonal endocrine cell clusters.
  • By contrast, it was absent in islets and ductal or acinar structures.
  • Our results indicate that monohormonal endocrine cell clusters represent a minute form of microadenomas.
  • Islet hyperplasia does not seem to be an obligatory stage in pancreatic MEN1-associated tumor development.

  • [Title] 672 patients with acinar cell carcinoma of the pancreas: a population-based comparison to pancreatic adenocarcinoma.
  • BACKGROUND: Acinar cell carcinoma (ACC) is a rare cancer of the pancreas accounting for approximately 1% of nonendocrine tumors.
  • OBJECTIVE: Our goal was to evaluate a large population-based cohort of patients with ACC and compare their demographic factors and outcomes to those of patients with pancreatic adenocarcinoma (PA).
  • The mean age at the time of diagnosis was significantly lower for ACC than PA (56 years vs 70 years, P < .001).
  • Multivariate Cox proportional hazards regression model results suggested patients with ACC were less likely to die (hazard ratio = 0.241; 95% confidence interval, 0.22-0.27) than patients with PA after controlling for gender, race, stage, SEER region of diagnosis, and surgical resection status.

  • In this article we provide an overview of the newest data concerning the effect of non-alcoholic constituents of alcoholic beverages, especially of beer, on pancreatic secretion, and their possible role in alcoholic pancreatitis and pancreatic carcinoma.
  • The data indicate that non-alcoholic constituents of beer stimulate pancreatic enzyme secretion in humans and rats, at least in part, by direct action on pancreatic acinar cells.
  • Some non-alcoholic compounds of beer, such as quercetin, resveratrol, ellagic acid or catechins, have been shown to be protective against experimentally induced pancreatitis by inhibiting pancreatic secretion, stellate cell activation or by reducing oxidative stress.
  • Their relevance in beer-induced functional alterations of pancreatic cells leading to pancreatitis and pancreatic cancer in humans needs to be further evaluated.

  • Primary epithelial tumors of the pancreas are extremely uncommon in children, and among these, acinar cell carcinoma (ACC) is the most rare.
  • The histologic diagnosis of ACC was supported by both immunohistochemistry and electron microscopy.
  • Despite its rarity, ACC should be kept in the differential diagnosis of pediatric pancreatic exocrine tumors.
  • We also provide a comparison with an example of solid pseudopapillary tumor, another relatively infrequent epithelial tumor of the pancreas in the young.

  • [Title] The epigenetic regulators Bmi1 and Ring1B are differentially regulated in pancreatitis and pancreatic ductal adenocarcinoma.
  • Chronic pancreatitis and pancreatic ductal adenocarcinoma (PDAC) are associated with major changes in cell differentiation.
  • Polycomb proteins are epigenetic silencers expressed in adult stem cells; up-regulation of Polycomb proteins has been reported to occur in a variety of solid tumours such as colon and breast cancer.
  • We hypothesized that Polycomb might play a role in preneoplastic states in the pancreas and in tumour development/progression.
  • To test these ideas, we determined the expression of PRC1 complex proteins (Bmi1 and Ring1b) during pancreatic development and in pancreatic tissue from mouse models of disease: acute and chronic pancreatic injury, duct ligation, and in K-Ras(G12V) conditional knock-in and caerulein-treated K-Ras(G12V) mice.
  • The study was extended to human pancreatic tissue samples.
  • To obtain mechanistic insights, Bmi1 expression in cells undergoing in vitro exocrine cell metaplasia and the effects of Bmi1 depletion in an acinar cancer cell line were studied.
  • We found that Bmi1 and Ring1B are expressed in pancreatic exocrine precursor cells during early development and in ductal and islet cells-but not acinar cells-in the adult pancreas.
  • Bmi1 expression was induced in acinar cells during acute injury, in acinar-ductal metaplastic lesions, as well as in pancreatic intraepithelial neoplasia (PanIN) and PDAC.
  • Bmi1 knockdown in cultured acinar tumour cells led to changes in the expression of various digestive enzymes.
  • Our results suggest that Bmi1 and Ring1B are modulated in pancreatic diseases and could contribute differently to tumour development.

  • Pancreatoblastoma (PB), or infantile pancreatic carcinoma, is an extremely rare pancreatic tumor in childhood, comprising 0.5% of pancreatic non-endocrine tumors.
  • Mechanical obstruction of the upper duodenum and gastric outlet by tumor in the head of the pancreas may be associated with vomiting, jaundice and gastrointestinal bleeding.
  • Histologically, PB is characterized with distinct acinar and squamoid cell differentiation.
  • The majority of these tumors arise in the head of the pancreas.
  • Ultrasound and CT scan may be useful but preoperative diagnosis is often quite difficult.
  • On the whole, PB is regarded to be a curable tumor; hence the clinical diagnosis should be made early.
  • Awareness of this rare tumor of pancreas is essential for early detection and proper management.
  • The author review the clinical presentation, etiology, diagnosis, treatment and prognosis of PB in this presentation.

  • Acinar cell carcinoma is an uncommon type of carcinoma of the pancreas that can exceptionally arise in ectopic pancreatic tissue.
  • Herein, we report a case of a 52-year-old man with pancreatic-type acinar cell carcinoma of the stomach and concomitant pancreatic metaplasia of the adjacent nonneoplastic gastric mucosa.
  • There was neither clinical nor radiographic evidence of a tumor in the pancreas itself.
  • The neoplastic cells and those of the adjacent metaplastic mucosa were both strongly immunoreactive for alpha-1-antitrypsin, consistent with pancreatic acinar cell differentiation.
  • Ectopic pancreatic-type acinar cell carcinoma is an extremely rare condition, having been previously reported only in 5 occasions, none of them in association with pancreatic acinar cell metaplasia of the gastric mucosa.

  • [Title] Pten constrains centroacinar cell expansion and malignant transformation in the pancreas.
  • To determine the role of the phosphatidylinositol 3-kinase (PI3-K) pathway in pancreas development, we generated a pancreas-specific knockout of Pten, a negative regulator of PI3-K signaling.
  • Knockout mice display progressive replacement of the acinar pancreas with highly proliferative ductal structures that contain abundant mucins and express Pdx1 and Hes1, two markers of pancreatic progenitor cells.
  • We provide evidence that ductal metaplasia results from the expansion of centroacinar cells rather than transdifferentiation of acinar cells.
  • These results indicate that Pten actively maintains the balance between different cell types in the adult pancreas and that misregulation of the PI3-K pathway in centroacinar cells may contribute to the initiation of pancreatic carcinoma in vivo.

  • [Title] Matrix metalloproteinase 7 controls pancreatic acinar cell transdifferentiation by activating the Notch signaling pathway.
  • Acinar-to-ductal metaplasia in the pancreas is associated with an increased risk for tumorigenesis.
  • Molecular dissection of this process in vitro has shown that primary acinar cells, in response to EGF receptor ligands, can transdifferentiate into duct-like epithelia, passing through a nestin-positive intermediate, in a Notch pathway-dependent manner.
  • Here, we show that in vitro acinar transdifferentiation depends on matrix metalloproteinase 7 (MMP-7), a proteinase expressed in most metaplastic epithelia in vivo.
  • MMP-7 was found to be required for Notch activation, which leads to dedifferentiation of acinar cells to the nestin-positive transitional cell.
  • Besides being necessary for acinar transdifferentiation, it was found that MMP-7 activity was sufficient to induce the process, indicating that molecular signals capable of initiating MMP-7 expression also have the potential to induce formation of metaplastic epithelia in the pancreas.

  • [Title] Acinar cell carcinoma of the pancreas: an institutional series of resected patients and review of the current literature.
  • INTRODUCTION: Acinar cell carcinoma (ACC) is a rare, malignant neoplasm with a generally poor prognosis.
  • MATERIALS AND METHODS: The Johns Hopkins pathology prospective database was reviewed from 1988 to 2006 to identify patients with pancreatic neoplasms possessing features of acinar cell differentiation.
  • Overall median survival and disease-free survival were 33 and 25 months, respectively, as compared to a median survival of 18 months for pancreatic adenocarcinoma.
  • CONCLUSION: Acinar cell carcinomas are rare, aggressive neoplasms that are difficult to diagnose and treat.
  • These lesions have a better prognosis than the more common pancreatic adenocarcinomas.

  • [Title] Fine-needle aspiration cytology of pancreatic somatostatinoma: the importance of immunohistochemistry for the cytologic diagnosis of pancreatic endocrine neoplasms.
  • Pancreatic somatostatinoma is a rare pancreatic endocrine neoplasm representing as little as 1% of pancreatic endocrine neoplasms (PENs).
  • The histologic features of this tumor are like those of other PENs, except that it commonly forms acinar structures and often has cells with abundant, granular cytoplasm.
  • We discuss the cytologic and immunohistochemical findings of these two cases and the cytologic similarities these neoplasms share with pancreatic acinar-cell carcinoma (PACC).
  • We review the cytologic features of PEN and PACC and discuss the importance of cell block immunohistochemistry in the diagnosis of pancreatic neoplasia sampled by EUS-guided FNA.

  • [Title] Pancreatic acinar cell carcinoma: a multi-institutional study.
  • INTRODUCTION: The presentation and outcome of patients with acinar cell carcinoma (ACC) of the pancreas compared to the more common ductal cell adenocarcinoma (DCA) may be distinct.
  • American Joint Commission on Cancer tumor stages were stage I (two), stage II (eight), stage III (four), and stage IV (three).
  • This is in contrast to 1,608 patients with ductal cell adenocarcinoma who underwent resection identified from recent literature reports where the average median survival was only 24 months.
  • CONCLUSION: Acinar cell carcinoma of the pancreas is rare and appears to have a presentation and outcome distinct from the more common pancreatic DCA.

  • [Title] Detection of pancreatic carcinomas by imaging lactose-binding protein expression in peritumoral pancreas using [18F]fluoroethyl-deoxylactose PET/CT.
  • BACKGROUND: Early diagnosis of pancreatic carcinoma with highly sensitive diagnostic imaging methods could save lives of many thousands of patients, because early detection increases resectability and survival rates.
  • Current non-invasive diagnostic imaging techniques have inadequate resolution and sensitivity for detection of small size ( approximately 2-3 mm) early pancreatic carcinoma lesions.
  • Therefore, we have assessed the efficacy of positron emission tomography and computer tomography (PET/CT) imaging with beta-O-D-galactopyranosyl-(1,4')-2'-deoxy-2'-[(18)F]fluoroethyl-D-glucopyranose ([(18)F]FEDL) for detection of less than 3 mm orthotopic xenografts of L3.6pl pancreatic carcinomas in mice.
  • [(18)F]FEDL is a novel radioligand of hepatocarcinoma-intestine-pancreas/pancreatitis-associated protein (HIP/PAP), which is overexpressed in peritumoral pancreatic acinar cells.
  • METHODOLOGY/PRINCIPAL FINDINGS: Dynamic PET/CT imaging demonstrated rapid accumulation of [(18)F]FEDL in peritumoral pancreatic tissue (4.04+/-2.06%ID/g), bi-exponential blood clearance with half-lives of 1.65+/-0.50 min and 14.14+/-3.60 min, and rapid elimination from other organs and tissues, predominantly by renal clearance.
  • Using model-independent graphical analysis of dynamic PET data, the average distribution volume ratio (DVR) for [(18)F]FEDL in peritumoral pancreatic tissue was estimated as 3.57+/-0.60 and 0.94+/-0.72 in sham-operated control pancreas.
  • The in situ analysis demonstrated that at least a 2-4 fold apparent lesion size amplification was achieved for submillimeter tumors and to nearly half a murine pancreas for tumors larger than 3 mm.
  • CONCLUSION/SIGNIFICANCE: We have demonstrated the feasibility of detection of early pancreatic tumors by non-invasive imaging with [(18)F]FEDL PET/CT of tumor biomarker HIP/PAP over-expressed in peritumoral pancreatic tissue.
  • Non-invasive non-invasive detection of early pancreatic carcinomas with [(18)F]FEDL PET/CT imaging should aid the guidance of biopsies and additional imaging procedures, facilitate the resectability and improve the overall prognosis.

  • [Title] High TRAIL death receptor 4 and decoy receptor 2 expression correlates with significant cell death in pancreatic ductal adenocarcinoma patients.
  • OBJECTIVES: The importance of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and TRAIL receptor expression in pancreatic carcinoma development is not known.
  • To reveal the putative connection of TRAIL and TRAIL receptor expression profile to this process, we analyzed and compared the expression profile of TRAIL and its receptors in pancreatic tissues of both noncancer patients and patients with pancreatic ductal adenocarcinoma (PDAC).
  • Annexin V binding revealed the apoptotic index in pancreas.
  • In addition, acinar cells from PDAC patients had higher DcR2 expression but lower death receptor 4 expression.
  • CONCLUSIONS: Differential alteration of TRAIL and TRAIL receptor expression profiles in PDAC patients suggest that the TRAIL/TRAIL receptor system may play a pivotal role during pancreatic carcinoma development.

  • [Title] Transition to pancreatic cancer in response to carcinogen.
  • BACKGROUND: It has become obvious that the traditional assumptions about the transition from normal pancreas to pancreatic cancer are incomplete.
  • Experimental studies reveal that the earliest changes during transition to pancreatic adenocarcinoma involve premalignant lesions that are derived from acinar, islet, and ductal cells.
  • As part of redifferentiation and transformation to adenocarcinoma, cells regain the characteristics of developing pancreas.
  • Elements significant in identifying precursor cell types include Pdx1, hedgehog signaling, notch signaling, and nestin, an intermediate filament expressed by precursor cell types.
  • CONCLUSIONS: Thus pancreatic carcinogenesis is not simply a matter of transition of ductal cells to cancer cells months after insult by the carcinogen; ductal cells are not the sole source transitioning to cancer, and PanINs are not the sole route to adenocarcinoma.
  • Tubular complexes, derived from multiple cell sources, are included in routes to pancreatic cancer.
  • Markers characteristic of developing pancreas are consistent with this transition.

  • [Title] Cystic lesions of the pancreas.
  • Although cystic tumors of the pancreas are relatively rare, they constitute an increasingly important category.
  • Advances in imaging and interventional techniques and the sharp drop in the mortality rate of pancreatic surgery have rendered pancreatic biopsies and resections commonplace specimens.
  • Consensus criteria for the distinction of these from the ordinary precursors of adenocarcinoma, the pancreatic intraepithelial neoplasia, were established.
  • The definition of mucinous cystic neoplasms was refined; ovarian-like stroma has now become almost a requirement for the diagnosis of mucinous cystic neoplasia, and defined as such, the propensity of these tumors to occur in perimenopausal women became even more striking.
  • The validity and clinical value of classifying the pancreatic cysts of mucinous type as adenoma, borderline, CIS and invasive have been established.
  • Greater accessibility of the pancreas afforded by improved invasive as well as noninvasive modalities has also increased the detection of otherwise clinically silent cystic tumors, which has led to the recognition of more innocuous entities such as acinar cell cystadenoma and squamoid cyst of pancreatic ducts.
  • Thus, significant developments have taken place in the classification and our understanding of pancreatic cystic tumors in the past few years, and experience with these lesions is likely to grow exponentially in the coming years.

  • Since human exposure to DLCs always occurs as a complex mixture, the toxic equivalency factor (TEF) methodology has been developed as a mathematical tool to assess the health risk posed by complex mixtures of these compounds.
  • The toxic equivalency of DLCs was nominated for evaluation because of the widespread human exposure to DLCs and the lack of data on the adequacy of the TEF methodology for predicting relative potency for cancer risk.
  • There were increases in hepatic cell proliferation in the 4,600 g/kg group at 14, 31, and 53 weeks.
  • At 2 years, a significant dose-related increase in hepatic toxicity was observed and was characterized by increased incidences of numerous lesions including hepatocyte hypertrophy, inflammation, oval cell hyperplasia, pigmentation, multinucleated hepatocyte, eosinophilic and mixed cell foci, diffuse fatty change, toxic hepatopathy, nodular hyperplasia, necrosis, bile duct hyperplasia and cyst, and cholangiofibrosis.
  • The incidence of carcinoma of the uterus in the 4,600 g/kg stop-exposure group was significantly greater than those in the vehicle control and 4,600 g/kg core study groups at 2 years.
  • A marginal increase in squamous cell carcinoma occurred in the 220 g/kg group.
  • At 2 years, there were marginally increased incidences of exocrine pancreatic adenoma or carcinoma in the 460, 1,000, and 4,600 g/kg core study groups.
  • Numerous nonneoplastic effects were seen in other organs including: adrenal cortical atrophy and cytoplasmic vacuolization, pancreatic acinar cell cytoplasmic vacuolization and arterial chronic active inflammation, follicular cell hypertrophy of the thyroid gland, inflammation and respiratory epithelial hyperplasia of the nose, and kidney pigmentation.
  • Occurrences of carcinoma in the uterus were considered to be related to the administration of PCB 118.
  • Occurrences of squamous cell carcinoma of the uterus and acinar neoplasms of the pancreas may have been related to administration of PCB 118.
  • Administration of PCB 118 caused increased incidences of nonneoplastic lesions in the liver, lung, adrenal cortex, pancreas, thyroid gland, nose, and kidney.

  • [Title] Absence of L1 in pancreatic masses distinguishes adenocarcinomas from poorly differentiated neuroendocrine carcinomas.
  • BACKGROUND: Pancreatic adenocarcinoma is a tumor with fatal outcome.
  • Cell adhesion molecules, such as L1 (CD171), have an essential function in tumor progression.
  • L1 has been shown to be specifically expressed in poorly differentiated neuroendocrine carcinomas of the pancreas.
  • The aim of this study was to determine the expression of L1 in pancreatic adenocarcinomas to evaluate whether L1 might differentiate between pancreatic carcinomas of neuroendocrine and ductal origin.
  • MATERIALS AND METHODS: L1 expression was retrospectively analyzed in 111 cases of pancreatic adenocarcinomas by immunohistochemistry on paraffin sections of primary tumors.
  • RESULTS: The focal expression of L1 was detected in 2 (2%) out of 111 pancreatic carcinomas only, the remaining 109 (98%) being L1-negative.
  • No expression was found in acinar or ductal cells of normal pancreatic tissue.
  • CONCLUSION: Our data suggest that L1 is expressed in few cases of pancreatic ductal adenocarcinoma.
  • Since L1 was previously found to be expressed specifically in neuroendocrine pancreatic carcinomas, its absence in unclear pancreatic masses might hint at a ductal origin for a malignant pancreatic tumor.

  • [Title] Distal pancreatectomy combined with celiac axis resection in treatment of carcinoma of the body/tail of the pancreas: a single-center experience.
  • The aim of this study was to assess the safety and efficacy of this extended procedure in treatment of advanced carcinoma of the body/tail of the pancreas.
  • METHODS: This was a retrospective analysis of 206 patients with carcinoma of the body/tail of the pancreas from January 2003 through June 2008.
  • Group A had longer mean operative time than group B (323 versus 225 min, P = 0.000); there was no difference in mean estimated blood loss, percentage of pancreatic fistula or median survival time (14 versus 15 months, P = 0.197).
  • CONCLUSIONS: DP combined with CA resection can be safely performed in certain patients with carcinoma of body/tail of the pancreas and significantly improves patient survival and quality of life.

  • [Title] Progressive metaplastic and dysplastic changes in mouse pancreas induced by cyclooxygenase-2 overexpression.
  • We generated transgenic mice (BK5.COX-2) in which elevation of COX-2 and its effectors trigger a metaplasia-dysplasia sequence in exocrine pancreas.
  • Histologic evaluation revealed a chronic pancreatitis-like state characterized by acinar-to-ductal metaplasia and a well-vascularized fibroinflammatory stroma that develops by 3 months.
  • By 6 to 8 months, strongly dysplastic features suggestive of pancreatic ductal adenocarcinoma emerge in the metaplastic ducts.
  • Increased proliferation, cellular atypia, and loss of normal cell/tissue organization are typical features in transgenic pancreata.
  • Alterations in biomarkers associated with human inflammatory and neoplastic pancreatic disease were detected using immunohistochemistry.
  • The abnormal pancreatic phenotype can be completely prevented by maintaining mice on a diet containing celecoxib, a well-characterized COX-2 inhibitor.
  • However, cell lines derived from spontaneous lesions are aggressively tumorigenic when injected into syngeneic or nude mice.

  • [Title] Pancreatic tumors in children and adolescents: the Italian TREP project experience.
  • INTRODUCTION: Malignant pancreatic tumors are exceedingly rare in pediatric age and their clinical features and treatment usually go unappreciated by most pediatric oncologists and surgeons.
  • METHODS: From January 2000 to July 2009, 21 patients <18 years old with pancreatic tumors were prospectively registered in the Italian cooperative TREP project dedicated to very rare pediatric tumors.
  • RESULTS: Tumor types were 4 pancreatoblastomas, 2 pancreatic carcinomas, 3 neoplasms of the endocrine pancreas, and 12 solid pseudopapillary tumors.
  • Three of the four patients with pancreatoblastoma had advanced disease at diagnosis and were given chemotherapy; at the time of this report, three patients were alive in first remission, while one died due to treatment toxicity.
  • Both the cases of pancreatic carcinoma had the acinar cell subtype and successfully underwent pancreaticoduodenectomy with complete tumor resection, remaining without evidence of disease at the time of this analysis.
  • The histological diagnoses of the three endocrine tumors were a malignant islet cell tumor, a gastrinoma, and a well-differentiated tumor.
  • All 12 patients with solid pseudopapillary tumors underwent complete tumor resection and were given no adjuvant treatment; 11 were alive in first remission, while one experienced a local and distant relapse 5 years after diagnosis.
  • CONCLUSIONS: Surgery remains the keystone of treatment for pancreatic tumors in pediatric age as in adults.
  • The TREP project shows that prospective cooperative studies are feasible even for such very rare tumors as these and may serve as a model for developing international cooperative schemes.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Microadenocarcinoma of the pancreas.
  • BACKGROUND: Microadenocarcinoma (MA) of the pancreas is a rare kind of neoplasm, whose status as an independent tumor entity is still a matter of controversy.
  • Cells of MA were morphologically uniform and were less pleomorphic than those of the ductal adenocarcinoma.
  • Immunohistochemistry revealed that MA, though with a certain extent of epithelial differentiation, possesses a different immunological phenotype from those of ductal carcinoma, acinar cell carcinoma, and endocrine tumors.
  • Genetic analysis showed no abnormality of p53, K-ras, and beta-catenin, which were usually mutated in pancreatic ductal adenocarcinoma.
  • CONCLUSION: Therefore, we suggest that MA should be taken as an independent tumor entity rather than a kind of growth pattern, but a final decision should be reached after cautious differential diagnosis of other kinds of pancreatic neoplasms.

  • [Title] Diagnostic approach to pancreatic tumors with the specimens of endoscopic ultrasound-guided fine needle aspiration.
  • Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) has enabled clinicians to histologically diagnose pancreatic tumors.
  • Using immunostaining of CK7, CDX2, neuroendocrine markers and KRAS mutation analysis, we examined 57 FNA cell block sections and 61 surgically-resected specimens (25 invasive ductal carcinomas, 25 endocrine tumors, and 11 acinar cell tumors).
  • In the majority of the matched pairs, the diagnoses between EUS-FNA and surgical specimens were concordant using the following criteria: neuroendocrine markers negative, CK7 positive, and mutated KRAS gene for invasive ductal carcinomas; neuroendocrine markers diffusely positive, CK7 and CDX2 negative, and wild-type KRAS gene for well-differentiated endocrine tumors; and neuroendocrine markers no more than focal positive, CK7 and CDX2 with various staining patterns, and wild-type KRAS gene for acinar cell carcinomas.
  • The usefulness of these markers was confirmed using 13 additional pancreatic tumors, prospectively.
  • Although minimal in selection, these markers are helpful in making diagnosis from EUS-FNA specimens of the major pancreatic tumors.

  • OBJECTIVES: Acinar cell carcinoma (ACC) of the pancreas is a rare tumor, and many aspects remain unclear because no large-scale clinical studies have been conducted.
  • METHODS: The present study investigated the clinical characteristics, treatment, and therapeutic outcomes of 115 patients registered in the Pancreatic Cancer Registry of the Japan Pancreas Society, and therapeutic plans were reviewed.
  • CONCLUSIONS: Confirming the diagnosis of ACC preoperatively is difficult, but this diagnosis should be kept in mind while planning surgery for ordinary pancreatic cancer.
  • Once the diagnosis has been confirmed, a possibility of surgical resection should be pursued to achieve better prognosis.

  • [Title] Hypothetical progression model of pancreatic cancer with origin in the centroacinar-acinar compartment.
  • OBJECTIVES: Based mainly on animal models, 2 lesions have been suggested as possible precursors of pancreatic ductal adenocarcinoma (PDAC): pancreatic intraepithelial neoplasia (PanIN) and tubular complexes (TCs).
  • The aim of the study was to find support for either of the 2 models through the analysis of a large panel of human pancreatic tissues.
  • In 50% to 70% of the cases with TC and associated PanIN, a transitional zone of acinar-ductular transformation with mucinous differentiation of the ductular epithelium was identified.
  • Expression of acinar and centroacinar markers was detected in TC, in the ductular structures of the transitional zones, as well as within the epithelium of mature PanINs.
  • A progression model that originates in the centroacinar-acinar compartment and ends with the development of PanIN lesions is suggested.

  • [Title] Ras activity in acinar cells links chronic pancreatitis and pancreatic cancer.
  • The relationship between chronic pancreatitis (CP) and pancreatic ductal adenocarcinoma (PDAC) is unclear.
  • However, we have recently found that excessive activity within the Ras signaling pathway can lead to acinar cell death or metaplasia and is associated with the development of fibrosis resembling CP and the development of PDAC from acinar cells through the full complement of preneoplastic (pancreatic intraepithelial neoplasia) lesions.

  • [Title] Subcutaneous fat necrosis as the presenting feature of a pancreatic carcinoma: the challenge of differentiating endocrine and acinar pancreatic neoplasms.
  • The association between pancreatic panniculitis and pancreatic disease is well described, but differentiation among the neoplastic causes of the syndrome remains difficult due to substantial overlap in histological and immunohistochemical features.
  • We report a case of subcutaneous fat necrosis as the presenting feature in a 61-year-old man with metastatic carcinoma of pancreatic origin.
  • Previous pathological evaluation of the patient's liver biopsy led to an initial diagnosis of adenocarcinoma of unknown primary site.
  • One month later, the patient presented with pancreatic panniculitis, prompting further investigation.
  • Immunohistochemistry was consistent with neuroendocrine differentiation, but the patient rapidly decompensated and died before the evaluation was complete, leaving the definitive diagnosis in question.
  • In our review of the published reports of tumor types associated with pancreatic panniculitis, we found that immunohistochemical staining and electron microscopy can and should be used in conjunction with clinical correlation to accurately differentiate neuroendocrine tumors from carcinomas with acinar cell features.
  • Accurate diagnosis of these tumors is necessary to determine prognosis and define appropriate therapy.

  • [Title] MicroRNA expression abnormalities in pancreatic endocrine and acinar tumors are associated with distinctive pathologic features and clinical behavior.
  • PURPOSE: We investigated the global microRNA expression patterns in normal pancreas, pancreatic endocrine tumors and acinar carcinomas to evaluate their involvement in transformation and malignant progression of these tumor types.
  • MATERIALS AND METHODS: Using a custom microarray, we studied the global microRNA expression in 12 nontumor pancreas and 44 pancreatic primary tumors, including 12 insulinomas, 28 nonfunctioning endocrine tumors, and four acinar carcinomas.
  • RESULTS: Our data showed that a common pattern of microRNA expression distinguishes any tumor type from normal pancreas, suggesting that this set of microRNAs might be involved in pancreatic tumorigenesis; the expression of miR-103 and miR-107, associated with lack of expression of miR-155, discriminates tumors from normal; a set of 10 microRNAs distinguishes endocrine from acinar tumors and is possibly associated with either normal endocrine differentiation or endocrine tumorigenesis; miR-204 is primarily expressed in insulinomas and correlates with immunohistochemical expression of insulin; and the overexpression of miR-21 is strongly associated with both a high Ki67 proliferation index and presence of liver metastasis.
  • CONCLUSION: These results suggest that alteration in microRNA expression is related to endocrine and acinar neoplastic transformation and progression of malignancy, and might prove useful in distinguishing tumors with different clinical behavior.

  • Acinar cell carcinomas and pancreatoblastomas are malignant tumors of the pancreas, showing predominantly acinar differentiation characterized by the immunohistochemical expression of pancreatic enzymes.
  • Histologically, they usually display acinar and/or solid patterns, but may occasionally also exhibit cystic structures.
  • Acinar cell carcinomas predominantly occur in adults, pancreatoblastomas in children.

  • [Title] Acinar cell carcinoma of the pancreas in the United States: prognostic factors and comparison to ductal adenocarcinoma.
  • INTRODUCTION: Pancreatic acinar cell carcinoma (ACC) is a rare tumor with poorly defined prognosis.
  • OBJECTIVE: Our objective was to compare a large population of patients with ACC to pancreatic ductal cell adenocarcinoma (DCC) in order to determine distinguishing characteristics and to assess survival.
  • METHODS: Patients were identified from the National Cancer Database.
  • Patients with ACC were more likely to be male, white, and have larger tumor size, no nodal involvement, or pancreatic tail tumors.
  • Aggressive surgical resection with negative margins is associated with long-term survival in these more favorable pancreatic cancers.

  • [Title] Endoscopic ultrasound-guided fine-needle aspiration cytology diagnosis of solid pseudopapillary tumor of the pancreas: a case report and literature review.
  • We describe the clinical, imaging and cytopathological features of solid pseudopapillary tumor of the pancreas (SPTP) diagnosed by endoscopic ultrasound-guided (EUS-guided) fine-needle aspiration (FNA).
  • Computed tomography (CT) analysis revealed a mass of the pancreatic tail with solid and cystic consistency.
  • EUS confirmed the mass, both in body and tail of the pancreas, with distinct borders, which caused dilation of the peripheral part of the pancreatic duct (major diameter 3.7 mm).
  • Biopsy confirmed the above cytologic diagnosis.
  • EUS-guided FNA diagnosis of SPTP is accurate.
  • EUS findings, cytomorphologic features and immunostains of cell block help distinguish SPTP from pancreatic endocrine tumors, acinar cell carcinoma and papillary mucinous carcinoma.

  • [Title] Acinar cell carcinoma of the pancreas metastatic to the ovary: a report of 4 cases.
  • We report 4 cases of acinar cell carcinoma of the pancreas, 3 presenting as metastases in the ovary, the first report of this circumstance, which may pose a broad differential diagnosis and caused significant diagnostic difficulty in all the cases.
  • In 3 cases, the ovarian tumors were detected before the pancreatic tumor; in 1 case, a large abdominal mass and ovarian tumors were discovered synchronously.
  • Two cases had a predominant acinar growth pattern of cells with brightly eosinophilic, granular cytoplasm.
  • The main differential diagnostic consideration was well-differentiated neuroendocrine neoplasm (carcinoid tumor); positive immunostaining with antibodies against chymotrypsin and trypsin and negative immunostaining with antibodies against synaptophysin and chromogranin helped exclude this diagnosis.
  • We observed focal alpha-inhibin immunostaining in 2 cases, which may represent a potential diagnostic pitfall, as a Sertoli cell tumor or unusual granulosa cell tumor may also enter the differential diagnosis.
  • Inclusion of antibodies against the pancreatic enzymes chymotrypsin and trypsin in the immunohistochemical panel is critical in establishing the correct diagnosis and should be considered when evaluating ovarian tumors with architectural (mainly acinar) and cytologic (granular eosinophilic cytoplasm) characteristics that should bring a metastatic acinar cell carcinoma into consideration.

  • [Title] Acinar cell carcinoma of the pancreas: is the absence of neuroendocrine component related to a more malignant behavior?
  • BACKGROUND/AIMS: Acinar cell carcinomas are uncommon malignant tumors of the pancreas, accounting for 1-2% of all the cases of exocrine pancreatic tumor.
  • Some authors have estimated acinar cell tumors to be as aggressive as ductal adenocarcinoma of the pancreas whereas other series showed acinar cell tumors to have a favorable clinical outcome.
  • METHODOLOGY: With the aim to evaluate the possible relationship between the presence of neuroendocrine differentiation and behavior of these tumors, the authors reviewed all patients presenting acinar cell carcinoma of the pancreas in the last 5 years with emphasis in the immunohistochemical evaluation.
  • This data suggests that this tumor is less aggressive than ductal adenocarcinoma and even with nodal involvement, long-term survival after complete resection can be achieved.
  • Due to the rarity of this pancreatic tumor, this relationship remains to be confirmed with a multicentric study including a larger number of patients.

  • [Title] Expression patterns of epiplakin1 in pancreas, pancreatic cancer and regenerating pancreas.
  • Here we analyzed the expression patterns of Eppk1 in the developing and adult pancreas in the mice.
  • In the embryonic pancreas, Eppk1+/Pdx1+ and Eppk1+/Sox9+ pancreatic progenitor cells were observed in early pancreatic epithelium.
  • In the adult pancreas, Eppk1 is expressed in centroacinar cells (CACs) and in duct cells.
  • Eppk1 is observed in pancreatic intraepithelial neoplasia (PanIN), previously identified as pancreatic ductal adenocarcinoma (PDAC) precursor lesions.
  • In addition, the expansion of Eppk1-positive cells occurs in a caerulein-induced acute pancreatitis, an acinar cell regeneration model.
  • These results suggest that Eppk1 serves as a useful marker for detecting pancreatic progenitor cells in developing and regenerating pancreas.

  • [Title] Keratin 8 sequence variants in patients with pancreatitis and pancreatic cancer.
  • Transgenic mice over-expressing human KRT8 display pancreatic mononuclear infiltration, interstitial fibrosis and dysplasia of acinar cells resulting in exocrine pancreatic insufficiency.
  • This prompted us to investigate KRT8 polymorphisms in patients with pancreatic disorders.
  • The KRT8 Y54H and G62C polymorphisms were assessed in a cohort of patients with acute and chronic pancreatitis of various aetiologies or pancreatic cancer originating from Austria (n=16), the Czech Republic (n=90), Germany (n=1698), Great Britain (n=36), India (n=60), Italy (n=143), the Netherlands (n=128), Romania (n=3), Spain (n=133), and Switzerland (n=129).
  • The frequency of G62C did not differ between patients with acute or chronic pancreatitis, pancreatic adenocarcinoma and control individuals.
  • Our data suggest that the KRT8 alterations, Y54H and G62C, do not predispose patients to the development of pancreatitis or pancreatic cancer.

  • Since human exposure to DLCs always involves a complex mixture, the toxic equivalency factor (TEF) methodology has been developed as a mathematical tool to assess the health risk posed by complex mixtures of these compounds.
  • The toxic equivalency of DLCs was nominated for evaluation because of the widespread human exposure to DLCs and the lack of data on the adequacy of the TEF methodology for predicting relative potency for cancer risk.
  • TCDD (dioxin) was selected for study by the National Toxicology Program as a part of the dioxin TEF evaluation to assess the cancer risk posed by complex mixtures of polychlorinated dibenzodioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and PCBs.
  • HEPATIC CELL PROLIFERATION DATA: To evaluate hepatocyte replication, analysis of labeling of replicating hepatocytes with 5-bromo-2'-deoxyuridine was conducted at the 14-, 31-, and 53-week interim evaluations.

  • [Title] A spontaneous acinar cell carcinoma model for monitoring progression of pancreatic lesions and response to treatment through noninvasive bioluminescence imaging.
  • PURPOSE: We have generated an EL1-luc/TAg transgenic mouse model that develops spontaneous and bioluminescent acinar cell carcinomas.
  • RESULTS: EL1-luc/TAg transgenic mice showed pancreas-specific bioluminescence signal before tumor progression and produced increasing light emission from the onset of the pancreatic acinar cell carcinomas.
  • Progression of the primary acinar cell carcinoma was accompanied by emergence of metastatic lesions in the abdominal organs, including liver and gastrointestinal fat tissues.
  • CONCLUSIONS: The EL1-luc/TAg mouse provides a noninvasive approach for monitoring spontaneous acinar cell carcinoma development and comprises a convenient tool for the evaluation of novel therapeutics against pancreatic cancers.

  • [Title] Liver metastases of pancreatic acinar cell carcinoma with marked nuclear atypia and pleomorphism diagnosed by EUS FNA cytology: a case report with emphasis on FNA cytological findings.
  • BACKGROUND: Acinar cell carcinoma of the pancreas is a rare neoplasm.
  • Unlike ductal adenocarcinomas, endocrine tumors, and solid pseudopapillary tumors of the pancreas with their characteristic FNA cytological features, acinar cell carcinomas pose a particular diagnostic challenge by sharing many cytomorphologic features with endocrine tumors of the pancreas.
  • Computed tomography revealed a 7.8 x 7.3 cm irregular, partially cystic mass in the body and tail of the pancreas, and two lesions in the liver compatible with metastases.
  • FNA cytology revealed abundant, loosely cohesive clusters of malignant epithelial cells with vaguely acinar and trabecular formations.
  • A pancreatic endocrine tumor was suspected initially, but acinar cell carcinoma of the pancreas was confirmed by immunohistochemistry, cytochemical and ultrastructural studies.
  • CONCLUSION: We describe a case of pancreatic acinar cell carcinoma with unusual cytomorphologic features mimicking an endocrine tumor of pancreas, encountered in endoscopic ultrasound-guided fine needle aspiration of a metastatic liver mass and discuss the diagnostic approach for this unusual pancreatic tumor in fine needle aspiration cytology.

  • [Title] Notch and Kras reprogram pancreatic acinar cells to ductal intraepithelial neoplasia.
  • Efforts to model pancreatic cancer in mice have focused on mimicking genetic changes found in the human disease, particularly the activating KRAS mutations that occur in pancreatic tumors and their putative precursors, pancreatic intraepithelial neoplasia (PanIN).
  • The basis for this selective response is unknown, and it is similarly unknown what cell types in the mature pancreas actually contribute to PanINs.
  • One clue comes from the fact that PanINs, unlike most cells in the adult pancreas, exhibit active Notch signaling.
  • We hypothesize that Notch, which inhibits differentiation in the embryonic pancreas, contributes to PanIN formation by abrogating the normal differentiation program of tumor-initiating cells.
  • Through conditional expression in the mouse pancreas, we find dramatic synergy between activated Notch and Kras in inducing PanIN formation.
  • Furthermore, we find that Kras activation in mature acinar cells induces PanIN lesions identical to those seen upon ubiquitous Kras activation, and that Notch promotes both initiation and dysplastic progression of these acinar-derived PanINs, albeit short of invasive adenocarcinoma.
  • At the cellular level, Notch/Kras coactivation promotes rapid reprogramming of acinar cells to a duct-like phenotype, providing an explanation for how a characteristically ductal tumor can arise from nonductal acinar cells.

  • [Title] AgNOR count and subjective AgNOR pattern assessment (SAPA) score in carcinoma of the pancreatic head including periampullary tumors.
  • CONTEXT: Only a few studies are available in the literature regarding the AgNOR (argyrophilic nucleolar organizer region) count in pancreatic adenocarcinoma but studies on the SAPA (subjective AgNOR pattern assessment) score are completely lacking.
  • OBJECTIVE: We attempted to estimate the AgNOR count and the SAPA score in carcinoma of the pancreatic head including periampullary tumors and to correlate them with other various clinico-histological parameters.
  • SETTING: Patients undergoing pancreatic resection at the University Hospital, Banaras Hindu University, Varanasi, India.
  • PATIENTS: Twenty-four cases of carcinoma of the pancreatic head including periampullary tumors.
  • In addition, on the resected specimen of the pancreas, the area which was normal was chosen and, in that normal tissue, the AgNOR was also studied.
  • RESULTS: The values of the AgNOR count and the SAPA score were significantly higher in cases of pancreatic cancer than in the healthy pancreas.
  • The AgNOR count was 1.6+/-0.1 in the healthy pancreas while it was 2.8+/-0.5 in cases of pancreatic carcinoma (P<0.001).
  • The SAPA score was 5.6+/-0.2 in the healthy pancreas while it was 8.0+/-1.4 in pancreatic carcinoma (P<0.001).
  • Periampullary tumors had a significantly lower (P<0.001) AgNOR count (2.7+/-0.06) and SAPA score (7.8+/-0.2) as compared to carcinoma of the head of the pancreas (AgNOR count 3.3+/-0.03 and SAPA score 9.2+/-0.7).
  • Well-differentiated carcinomas had significantly lower AgNOR counts as compared to other tumors except acinar cell carcinomas since acinar cell carcinomas are also well-differentiated tumors.
  • The SAPA score was also higher in moderately-differentiated tumors and the difference between moderately-differentiated tumor and other types of tumors was significant although there was no significant difference between cystadenocarcinomas and unclassified tumors, and between acinar cell carcinomas and well-differentiated tumors on SAPA scoring.

  • [Title] Colonic carcinoma with a pancreatic acinar cell differentiation. A case report.
  • A case of a colonic carcinoma showing a pancreatic acinar cell differentiation is described for the first time.
  • Histologically, tumour cells were organized in acinar structures resembling pancreatic acini and in solid nests and ribbons or diffusely infiltrated as poorly cohesive cells.
  • Immunohistochemically, both acinar and diffuse patterns of growth showed an intense staining for trypsin, chymotrypsin and BCL10 and a weaker immunoreactivity for lipase and carboxyl ester hydrolase.
  • No immunoreactivity was observed for cytokeratin 7, MUC1, MUC5AC, pancreatic amylase or PDX1.
  • There was no evidence of a pancreatic acinar cell carcinoma or of heterotopic pancreatic tissue.
  • A colonic origin ought to be suspected when a metastatic carcinoma of unknown primary shows an acinar differentiation.

  • [Title] Pancreatic regenerating gene I and acinar cell differentiation: influence on cellular lineage.
  • OBJECTIVES: Pancreatic regenerating gene I (reg I) has been implicated in cellular differentiation.
  • Acinar cells can transdifferentiate into other pancreatic-derived cells, and we postulated that changes in intracellular levels of reg I would affect the state of differentiation.
  • Specifically, amylase mRNA and protein levels increased in SS cells, whereas AS cells showed increased pancreatic and duodenal homeobox 1 (Pdx1) and insulin mRNAs and cytokeratin protein.
  • CONCLUSIONS: These data demonstrate that in acinar cells, reg I overexpression is linked to acinar cell differentiation, whereas inhibition of reg I leads to beta cell and possibly ductal phenotype.
  • Reg I expression in acinar cells is important in maintaining pancreatic cell lineage, and when decreased, cells can dedifferentiate and move toward becoming other pancreatic cells.

  • We report on the case of a 19-year-old male with an alpha-fetoprotein (AFP)-producing acinar cell carcinoma of the pancreas.
  • Originally, AFP was thought to be specific to hepatocellular carcinoma and germ cell tumours.
  • Rare cases of acinar cell carcinomas of the pancreas were found to express AFP.
  • When present, AFP expression is useful for diagnosis and as a marker for monitoring therapeutic response and recurrence of the disease.

  • [Title] Notch and Kras in pancreatic cancer: at the crossroads of mutation, differentiation and signaling.
  • Activating mutations in the KRAS proto-oncogene occur almost ubiquitously in pancreatic ductal adenocarcinoma (PDAC) and in its putative precursor lesions, pancreatic intraepithelial neoplasia (PanIN).
  • Conditional expression of an activated Kras allele in the mouse pancreas produces a model that faithfully recapitulates PanIN formation and progression to PDAC.
  • Importantly, although nearly every cell in the pancreata of these mice express activated Kras, only a very small minority of cells give rise to PanINs.
  • How the transforming activity of Kras is constrained in the pancreas remains unknown, and the cell types from which PanINs and PDAC arise are similarly unknown.
  • Here, we describe our recent results demonstrating that acinar cells are competent to form Kras-induced PanINs, and that active Notch signaling can synergize with Kras in PanIN initiation and progression.
  • Further efforts to understand how Notch and Kras synergize, as well as experiments to determine how other pancreatic cell types contribute to PDAC development, should aid in the development of new therapies and early detection techniques that are desperately needed for this cancer.

  • The aim of our studies was to compare the different CLDN expression patterns in normal pancreas cells, pancreatic endocrine tumors, adenocarcinomas, mucinous cystic tumors and acinar cell carcinomas.
  • ) In addition to the well-known CLDN-1 and -4 expression CLDN-2, -3 and -7 proteins were demonstrated in ductal cells, while CLDN-3 and -7 proteins showed expression in acinar cells.
  • 4.) This is a first review on childhood acinar cell carcinoma causing Cushing syndrome.
  • The adenocarcinomas and cystic mucinous tumors of exocrine origin denoted CLDN-1, -2, -4 and -7 positivity, whereas acinar cell carcinomas expressed only CLDN-1 and -2.
  • Considering the CLDN expression observed in normal pancreas cells, it can be established that CLDN-1, -2 and -4 proteins are definitely markers of ductal differentiation, CLDN-1 protein of acinar and CLDN-3 of endocrine differentiation. 2).

  • [Title] Transgenic expression of CCK2 receptors sensitizes murine pancreatic acinar cells to carcinogen-induced preneoplastic lesions formation.
  • In humans, initial events of pancreatic carcinogenesis remain unknown, and the question of whether this cancer, which has a ductal phenotype, exclusively arises from duct cells has been raised.
  • Previous studies have demonstrated that transgenic expression of the CCK2 receptor in acinar cells of ElasCCK2 mice plays a role in the development of pancreatic neoplasia.
  • Transition of acinar cells into duct-like cells expressing Pdx1 and gastrin, as well as proliferation of acinar cells, were transiently observed in both transgenic and control mice.
  • Importantly, expression of the CCK2 receptor increased the susceptibility of pancreas to azaserine.
  • Indeed, treated ElasCCK2 mice exhibited larger areas of pancreatic acinar-ductal transition, increased cellular proliferation as well as larger adenomas areas vs. control mice.

  • We have encountered cases of unusual intraductal pancreatic neoplasms with predominant tubulopapillary growth.
  • ITPNs were solid and nodular tumors obstructing dilated pancreatic ducts and did not contain any visible mucin.
  • All the features of ITPN were distinct from those of other known intraductal pancreatic neoplasms, including pancreatic intraepithelial neoplasia, intraductal papillary mucinous neoplasm, and the intraductal variant of acinar cell carcinoma.
  • In conclusion, ITPNs can be considered to represent a new disease entity encompassing intraductal tubular carcinoma as a morphologic variant.

  • Pancreatic acinar cell carcinomas are rare, and little is reported on their chemotherapy.
  • We report a 49-year old male patient with pancreatic acinar cell carcinoma and multiple liver metastases, which responded to oral TS-1 and hepatic arterial infusion of cisplatin.
  • The patient underwent a partial hepatectomy, MCT abrasions and excision of the pancreatic tumor.
  • Postoperative pathological studies revealed metastases of acinar cell carcinoma to the liver and lymph nodes; the primary lesion was undetermined.
  • Abdominal CT one year after surgery revealed a pancreatic body tumor, which was surgically removed.
  • Pathological studies showed primary pancreatic acinar cell carcinoma, while previous metastases remained under control.

  • Since human exposure to DLCs always occurs as a complex mixture, the toxic equivalency factor (TEF) methodology has been developed as a mathematical tool to assess the health risk posed by complex mixtures of these compounds.
  • The toxic equivalency of DLCs was nominated for evaluation because of the widespread human exposure to DLCs and the lack of data on the adequacy of the TEF methodology for predicting relative potency for cancer risk.
  • Hepatic Cell Proliferation Data: To evaluate hepatocyte replication, analysis of labeling of replicating hepatocytes with 5-bromo-2'-deoxyuridine was conducted at the 14-, 31-, and 53-week interim evaluations.
  • At the end of the 2-year study, there were significantly increased incidences and severities of toxic hepatopathy characterized by hepatocyte hypertrophy, multinucleated hepatocytes, pigmentation, diffuse and focal fatty change, eosinophilic focus, nodular hyperplasia, cholangiofibrosis, oval cell hyperplasia, bile duct cysts, bile duct hyperplasia, necrosis, and portal fibrosis.
  • In addition, two animals in the highest dose group had hepatocellular carcinoma.
  • In addition, single occurrences of squamous cell carcinoma were seen in the top two dose groups.
  • Significantly increased incidences of squamous cell carcinoma (gingival) of the oral mucosa were seen at the end of the 2-year study and were accompanied by increased incidences of gingival squamous hyperplasia.
  • In the pancreas at 53 weeks, the incidence of acinar cytoplasmic vacuolization was significantly increased in the highest dose group.
  • At 2 years, increased incidences of acinar atrophy and acinar cytoplasmic vacuolization were seen in addition to pancreatic acinar neoplasms in dosed groups.
  • In the uterus at 2 years, there was a marginal increase in the incidence of squamous cell carcinoma in Group 5.
  • Numerous nonneoplastic effects were seen in other organs at the interim time points including atrophy of the thymus and follicular cell hypertrophy of the thyroid gland.

  • [Title] Current diagnosis and management of unusual pancreatic tumors.
  • BACKGROUND: The finding of a solid or cystic mass in the pancreas is becoming more common secondary to the increasing use of cross-sectional imaging and the improved sensitivity of such studies for the detection of pancreatic abnormalities.
  • Because of the aggressive natural history of pancreatic cancer, this has caused concern that all pancreatic abnormalities may be cancer as well as confusion over proper diagnostic and treatment algorithms.
  • This review provides an overview of the natural history, diagnostic considerations, and treatment recommendations for the less common tumors of the pancreas which can be misinterpreted as pancreatic cancer including: solid pseudopapillary tumors (SPT), acinar cell carcinoma (ACC), lymphoplasmacytic sclerosing pancreatitis (LPSP), primary pancreatic lymphoma (PPL), and metastatic renal cell carcinoma to the pancreas.
  • DATA SOURCES: A Medline search was conducted to identify studies investigating the clinicopathologic features, molecular genetics, pathogenesis, diagnosis, and treatment of SPT, ACC, LPSP, PPL, and pancreatic metastases.
  • CONCLUSIONS: It is often possible to obtain an accurate pretreatment diagnosis for these unusual pancreatic tumors and to successfully differentiate them from the more common pancreatic malignancies.
