BACKGROUND AND AIMS: To elucidate the efficacy of pancreatic juice cytology with the cell block method (CB-PJC) for the determination of surgery in patients with branch duct intraductal papillary mucinous neoplasm (BD-IPMN). METHODS: In 138 patients with BD-IPMN from whom pancreatic juice was collected under ERCP for CB-PJC, we retrospectively evaluated the following: (1) the rate of the CB-PJC successfully evaluated, (2) the ability of CB-PJC for the diagnosis of malignant BD-IPMNs and for the identification of pathological subtypes in resected BD-IPMNs, (3) the rate of development into invasive cancer and progression of BD-IPMNs in patients with BD-IPMN diagnosed as benignancy by CB-PJC, and (4) post-ERCP adverse events...

BACKGROUND AND AIMS: Currently, 3 guidelines are available for the management of pancreatic cysts. These guidelines vary in their indication for resection of high-risk cysts. We retrospectively compared the final pathological outcome of surgically removed pancreatic cysts with the indications for resection according to 3 different guidelines. METHODS: Patients who underwent pancreatic resection were extracted from our prospective pancreatic cyst database (2006-present)...

BACKGROUND AND AIMS: Intraductal papillary mucinous neoplasms (IPMNs) of the pancreas have been reported to be associated with an increased risk of developing extra-pancreatic malignancies. A common genetic background has been hypothesised to be responsible for such an association. Human chromosomal region 8q24 has been associated with many types of cancer. The majority of these associations lie at approximately 128 Mb on chromosome 8. We conducted a study in order to examine the association between IPMN and single nucleotide polymorphisms (SNPs) from the 8q24 region, namely rs10505477, rs6983267, rs7014346, rs6993464, previously reported to influence general cancer susceptibility...

OBJECTIVE: To evaluate the correlation between neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) values, and the presence of invasive carcinoma in patients with intraductal papillary mucinous neoplasm (IPMN). BACKGROUND: NLR and (PLR) are inflammatory markers that have been associated with overall survival in patients with invasive malignancies, including pancreatic cancer. METHODS: We retrospectively reviewed 272 patients who underwent surgical resection for histologically confirmed IPMN from January 1997 to July 2015...

OBJECTIVES: This study evaluated individual risks of malignancy and proposed a nomogram for predicting malignancy of branch duct type intraductal papillary mucinous neoplasms (BD-IPMNs) using the large database for IPMN. BACKGROUND: Although consensus guidelines list several malignancy predicting factors in patients with BD-IPMN, those variables have different predictability and individual quantitative prediction of malignancy risk is limited. METHODS: Clinicopathological factors predictive of malignancy were retrospectively analyzed in 2525 patients with biopsy proven BD-IPMN at 22 tertiary hospitals in Korea and Japan...

Early detection of pancreatic and periampullary neoplasms is critical to improve their clinical outcome. The present authors previously demonstrated that DNA hypermethylation of adenomatous polyposis coli (APC), histamine receptor H2 (HRH2), cadherin 13 (CDH13), secreted protein acidic and cysteine rich (SPARC) and engrailed-1 (EN-1) promoters is frequently detected in pancreatic tumor cells. The aim of the present study was to assess their prevalence in pancreatic juice of carcinomas of the pancreas and periampullary area...

Intraductal oncocytic papillary neoplasm (IOPN) of the pancreas is classified as a variant of intraductal papillary mucinous neoplasm (IPMN) in the WHO guidelines. However, the neoplastic cells of IOPNs are unique, with distinctive architecture/oncocytic cytoplasm. Although molecular/immunohistochemical features of other IPMN variants have been extensively studied, those of IOPNs have not been well characterized. Expression profile of antibodies associated with genetic alterations previously described for ductal adenocarcinomas (DAs) and IPMNs (SMAD4/β-catenin/p53/mesothelin/claudin-4) as well as antibodies to mucins and differentiation markers [MUC1/MUC2/MUC5AC/MUC6/CDX2/hepatocyte paraffin-1 (HepPar-1)] was investigated in 24 IOPNs and 22 IPMNs to assess the similarities/differences between these tumors...

INTRODUCTION: Side branch IPMN (SB-IPMN) of the pancreas has a malignancy rate between 10 and 20%. We hypothesized that surveillance at longer intervals on selected patients with SB-IPMN might be indicated. METHODS: This is a retrospective study of prospectively collected data of 276 patients presenting from 2000 to 2010. After 2007, we opted to screen our patients with longer intervals, initially at 12 months then 24 months using MR if no "worrisome features" were present...

INTRODUCTION: Main-duct intraductal papillary mucinous neoplasms of the pancreas (M-IPMN) are potentially malignant cystic neoplasms that can degenerate into invasive malignancy in 43 % of cases.1 Although laparoscopic pancreaticoduodenectomy and distal pancreatectomy have been previously described for the management of pancreatic neoplasms, laparoscopic total pancreatectomy is rarely described. We present a video demonstrating a laparoscopic spleen-preserving total pancreatectomy in a patient with M-IPMN...

Intraductal papillary mucinous neoplasms (IPMNs) are pancreatic cancer precursors incidentally discovered by cross-sectional imaging. Consensus guidelines for IPMN management rely on standard radiologic features to predict pathology, but they lack accuracy. Using a retrospective cohort of 38 surgically-resected, pathologically-confirmed IPMNs (20 benign; 18 malignant) with preoperative computed tomography (CT) images and matched plasma-based 'miRNA genomic classifier (MGC)' data, we determined whether quantitative 'radiomic' CT features (+/- the MGC) can more accurately predict IPMN pathology than standard radiologic features 'high-risk' or 'worrisome' for malignancy...

OBJECTIVE: To investigate using quantitative imaging to assess the malignant potential of intraductal papillary mucinous neoplasms (IPMNs) in the pancreas. BACKGROUND: Pancreatic cysts are identified in over 2% of the population and a subset of these, including intraductal papillary mucinous neoplasms (IPMNs), represent pre-malignant lesions. Unfortunately, clinicians cannot accurately predict which of these lesions are likely to progress to pancreatic ductal adenocarcinoma (PDAC)...

Pancreatic cancer is one of the most lethal tumors, and reliable detection of early-stage pancreatic cancer and risk diseases for pancreatic cancer is essential to improve the prognosis. As 260 genes were previously reported to be upregulated in invasive ductal adenocarcinoma of pancreas (IDACP) cells, quantification of the corresponding proteins in plasma might be useful for IDACP diagnosis. Therefore, the purpose of the present study was to identify plasma biomarkers for early detection of IDACP by using two proteomics strategies: antibody-based proteomics and liquid chromatography-tandem mass spectrometry (LC-MS/MS)-based proteomics...

Intraductal oncocytic papillary neoplasms (IOPNs) are cystic neoplasms with intraductal growth and complex papillae composed of oncocytic cells. IOPNs have been reported both in the pancreas and biliary tree, and are most likely closely related in these 2 locations. In the pancreas, these rare tumors are now considered 1 of the 4 histologic subtypes of intraductal papillary mucinous neoplasm (IPMN). Significant differences in histology, immunophenotype, and molecular genetics have been reported between IOPNs and other IPMN subtypes...

BACKGROUND: Solid pseudopapillary neoplasms of the pancreas (SPN) are rare tumors affecting mainly women. They show an activating mutation in CTNNB1, the gene for β-catenin, and consequently an overactivation of the Wnt/β-catenin pathway. This signaling pathway is implied in the pathogenesis of various aggressive tumors, including pancreatic adenocarcinomas (PDAC). Despite this, SPN are characterized by an unusually benign clinical course. Attempts to explain this lack of malignancy have led to the discovery of an aberrant expression of the transcription factor FLI1 in SPN...

BACKGROUND & AIMS: Little is known about the origin of pancreatic intraductal papillary mucinous neoplasms (IPMN). Pancreatic duct glands (PDGs) are gland-like outpouches budding off the main pancreatic ducts that function as progenitor niche for the ductal epithelium; they express gastric mucins and have characteristics of side-branch IPMN. We investigated whether PDGs are a precursor compartment for IPMN and the role of trefoil factor family 2 (TFF2)- a protein expressed by PDGs and the gastric mucosa that are involved in epithelial repair and tumor suppression...

OBJECTIVES: To evaluate and correlate computed tomography/magnetic resonance findings and histopathologic features of oncocytic intraductal papillary mucinous neoplasms (O-IPMNs). METHODS: Computed tomography/magnetic resonance examinations and resection specimens of 16 O-IPMNs were retrospectively reviewed. Qualitative and quantitative imaging features were analyzed according to "worrisome features" and "high risk stigmata." Correlations between radiological and histopathological findings were evaluated using Fisher test...

OBJECTIVES: Our aim was to establish and characterize a novel pancreatic ductal adenocarcinoma cell line from a patient in whom the origin of the invasive carcinoma could be traced back to the intraductal papillary mucinous neoplasm (IPMN) precursor lesion. METHODS: The primary patient-derived tumor was propagated in immunocompromised mice for 2 generations and used to establish a continuous in vitro culture termed ASAN-PaCa. Transplantation to fertilized chicken eggs confirmed the tumorigenic potential in vivo...
