Abstract
BACKGROUND Prognosis of perihilar cholangiocarcinoma (PHCC) is poor, and curative-intent resection is the most effective treatment associated with long-term survival. Surgery is technically demanding since it involves a major hepatectomy with en bloc resection of the caudate lobe and extrahepatic bile duct. Furthermore, to achieve negative margins, it may be necessary to perform concomitant vascular resection or pancreatoduodenectomy. Despite this aggressive approach, recurrence is often observed, considering 5-year recurrence-free survival below 15% and 5-year overall survival that barely exceeds 40%. SUMMARY The literature reports that survival rates are better in patients with negative margins, and surprisingly, R0 resections range between 19% and 95%. This variability is probably due to different surgical strategies and the pathologist's expertise with specimens. In fact, a proper pathological examination of residual disease should take into consideration both the ductal and the radial margin (RM) status. Currently, detailed pathological reports are lacking, and there is a likelihood of misinterpreting residual disease status due to the missing of RM description and the utilization of various definitions for surgical margins. KEY MESSAGES The aim of PHCC surgery is to achieve negative margins including RM. More clarity in reporting on RM is needed to define true radical resection and consistent design of oncological studies for adjuvant treatments.

Abstract
Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are rare and highly heterogeneous neoplasms whose incidence has markedly increased over the last decades. A grading system based on the tumor cells' proliferation index predicts high-risk for G3 NETs. However, low-to-intermediate grade (G1/G2) NETs have an unpredictable clinical course that varies from indolent to highly malignant. Cultures of human cancer cells enable to perform functional perturbation analyses that are instrumental to enhance our understanding of cancer biology. To date, no tractable and reliable long-term culture of G1/G2 NET has been reported to permit disease modeling and pharmacological screens. Here, we report of the first long-term culture of a G2 metastatic small intestinal NET that preserves the main genetic drivers of the tumor and retains expression patterns of the endocrine cell lineage. Replicating the tissue, this long-term culture showed a low proliferation index, and yet it could be propagated continuously without dramatic changes in the karyotype. The model was readily available for pharmacological screens using targeted agents and as expected, showed low tumorigenic capacity in vivo. Overall, this is the first long-term culture of NETs to faithfully recapitulate many aspects of the original neuroendocrine tumor.

Abstract
BACKGROUND The evaluation of surgical margins in resected perihilar cholangiocarcinoma (PHCC) remains a challenging issue. Both ductal (DM) and radial margin (RM) should be considered to define true radical resections (R0). Although DM status is routinely described in pathological reports, RM status is often overlooked. Therefore, the frequency of true R0 and its impact on survival might be biased. OBJECTIVE To improve the evaluation of RM status and investigate the impact of true R0 on survival. METHODS From 2014 to 2020, 90 patients underwent curative surgery for PHCC at Verona University Hospital, Verona, Italy. Both DM (proximal and distal biliary margin) and RM (hepatic, periductal, and vascular margin) status were evaluated by expert hepatobiliary pathologists. Patients with lymph-node metastases or positive surgical margins (R1) were candidates for adjuvant treatment. Clinicopathological and survival data were retrieved from an institutional database. RESULTS True R0 were 46% (41) and overall R1 were 54% (49). RM positivity resulted in being higher than DM positivity (48% versus 27%). Overall survival was better in patients with true R0 than in patients with R1 (median survival time: 53 vs. 28 months; p = 0.016). Likewise, the best recurrence-free survival was observed in R0 compared with R1 (median survival time: 32 vs. 15 months; p = 0.006). Multivariable analysis identified residual disease status as an independent prognostic factor of both OS (p = 0.009, HR = 2.68, 95% CI = 1.27-5.63) and RFS (p = 0.009, HR = 2.14, 95% CI = 1.20-3.83). CONCLUSION Excellent survival was observed in true R0 patients. The improved evaluation of RM status is mandatory to properly stratify prognosis and select patients for adjuvant treatment.

Abstract
OBJECTIVE The aim of this study was to reappraise the optimal number of examined lymph nodes (ELNs) in pancreatoduodenectomy (PD) for pancreatic ductal adenocarcinoma (PDAC). SUMMARY BACKGROUND DATA The well-established threshold of 15 ELNs in PD for PDAC is optimized for detecting 1 positive node (PLN) per the previous 7th edition of the American Joint Committee on Cancer (AJCC) staging manual. In the framework of the 8th edition, where at least 4 PLN are needed for an N2 diagnosis, this threshold may be inadequate for accurate staging. METHODS Patients who underwent upfront PD at 2 academic institutions between 2000 and 2016 were analyzed. The optimal ELN threshold was defined as the cut-point associated with a 95% probability of identifying at least 4 PLNs in N2 patients. The results were validated addressing the N-status distribution and stage migration. RESULTS Overall, 1218 patients were included. The median number of ELN was 26 (IQR 17-37). ELN was independently associated with N2-status (OR 1.27, P < 0.001). The estimated optimal threshold of ELN was 28. This cut-point enabled improved detection of N2 patients and stage III disease (58% vs 37%, P = 0.001). The median survival was 28.6 months. There was an improved survival in N0/N1 patients when ELN exceeded 28, suggesting a stage migration effect (47 vs 29 months, adjusted HR 0.649, P < 0.001). In N2 patients, this threshold was not associated with survival on multivariable analysis. CONCLUSION Examining at least 28 LN in PD for PDAC ensures optimal staging through improved detection of N2/stage III disease. This may have relevant implications for benchmarking processes and quality implementation.

Abstract
BACKGROUND Implementing a prospective lymphadenectomy protocol, we investigated the nodal yields and metastases per anatomical stations and nodal echelon following upfront pancreatoduodenectomy (PD) for cancer. Next, the relationship between the extension of nodal dissection, the number of examined and positive nodes (ELN/PLN), disease staging and prognosis was assessed. METHODS Lymphadenectomy included stations 5, 6, 8a-p, 12a-b-p, 13, 14a-b, 17, and jejunal mesentery nodes. Data were stratified by N-status, anatomical stations, and nodal echelons. First echelon was defined as stations embedded in the main specimen and second echelon as stations sampled as separate specimens. Recurrence and survival analyses were performed by using standard statistics. RESULTS Overall, 424 patients were enrolled from June 2013 through December 2018. The median number of ELN and PLN was 42 (interquartile range [IQR] 34-50) and 4 (IQR 2-8). Node-positive patients were 88.2%. The commonest metastatic sites were stations 13 (77.8%) and 14 (57.5%). The median number of ELN and PLN in the first echelon was 28 (IQR 23-34) and 4 (IQR 1-7). While first-echelon dissection provided enough ELN for optimal nodal staging, the aggregate rate of second-echelon metastases approached 30%. Nodal-related factors associated with recurrence and survival were N-status, multiple metastatic stations, metastases to station 14, and jejunal mesentery nodes. CONCLUSIONS First-echelon dissection provides adequate number of ELN for optimal staging. Nodal metastases occur mostly at stations 13/14, although second-echelon involvement is frequent. Only station 14 and jejunal mesentery nodes involvement was prognostically relevant. This latter station should be included in the standard nodal map and analyzed pathologically.

Abstract
INTRODUCTION Laparoscopic liver surgery is spreading, encouraged by technical and technological improvement. Both the obligated narrow space and the difficulty to modify it lead to a more complex approach to the lesions located in the posterosuperior portion of the liver. Surgical strategies such as the Caudal approach or the Diamond technique could ameliorate surgical procedure, but these areas remain a challenge and are still classified as complex. CLINICAL CASE We discuss the case of a 68 year old man with metachronous liver metastasis in the dorsal part of segment 8. We used portal phase CT-scan Dicom data to create Three-dimensional reconstruction, which was able to show the more distal branches of intraparenchymal structures. The reconstructed images were subsequently used to plan laparoscopic liver resection. DISCUSSION The capability of three-dimensional reconstruction to create a realistic image allows us to use ultrasound as a navigation tool. Exploiting these two technologies together, we arrived to regulate the resection stages by recognizing previously marked structures and searching them at every intervention phase. The strategy performed demonstrates both a high level of precision and the capability to predict intraparenchymal structures. CONCLUSION The advantages obtained from three-dimensional reconstruction are numerous in terms of either anatomical comprehension and technical precision, suggesting a potential improvement in surgical skill. Three-dimensional technology should be encouraged and spread to understand, in every single aspect, the potential of its use.

Abstract
Inflammatory/tumor-like lesions of the pancreas represent a heterogeneous group of diseases that can variably involve the pancreatic gland determining different signs and symptoms. In the category of inflammatory/tumor-like lesions of the pancreas, the most important entities are represented by chronic pancreatitis, which includes alcoholic, obstructive and hereditary pancreatitis, paraduodenal (groove) pancreatitis, autoimmune pancreatitis, lymphoepithelial cyst, pancreatic hamartoma and intrapancreatic accessory spleen. An in-depth knowledge of such diseases is essential, since they can cause severe morbidity and may represent a potential life-threatening risk for patients. Furthermore, in some cases the differential diagnosis with malignant tumors may be challenging. Herein we provide a general overview of all these categories, with the specific aim of highlighting their most important clinic-pathological hallmarks to be used in routine diagnostic activities and clinical practice.

Abstract
Benign biliary tumor are common lesions that are often an incidental finding in subjects who undergo medical imaging tests for other conditions. Most are true neoplasms while few result from reactive or malformative proliferation. Benign tumors have no clinical consequences, although the premalignant nature or potential for malignant transformation is of concern in some cases. The main practical problem for pathologists is the need to differentiate them from malignant biliary tumours, which is not always straightforward. Premalignant lesions of the bile duct have been described, although their incidence has been poorly characterized. These lesions include biliary mucinous cystic neoplasms, intraductal papillary neoplasms of the bile duct, and biliary intraepithelial neoplasia. In this article, histopathology of benign biliary tumors and biliary tumor precursors is discussed, with a focus on the main diagnostic criteria.

Abstract
Liver cancer represents the third leading cause of cancer-related death worldwide. Cholangiocarcinoma (CCA) is the second most common type of liver cancer after hepatocellular carcinoma, accounting for 10-15% of all primary liver malignancies. Both the incidence and mortality of CCA have been steadily increasing during the last decade. Moreover, most CCAs are diagnosed at an advanced stage, when therapeutic options are very limited. CCA may arise from any tract of the biliary system and it is classified into intrahepatic, perihilar, and distal CCA, according to the anatomical site of origin. This topographical classification also reflects distinct genetic and histological features, risk factors, and clinical outcomes. This review focuses on histopathology of CCA, its differential diagnoses, and its diagnostic pitfalls.

Abstract
Funding Acknowledgements Type of funding sources: None. Background Coronary artery disease (CAD) and aortic aneurysm (AA) share commons risk factors, such as hypertension, diabetes mellitus, hypercholesterolemia, and smoking. Cardiac assessment before aortic abdominal aneurysm (AAA) surgery is indicated for patients with symptomatic coronary artery disease (CAD). The usefulness of assessment of moderate/high-risk patients is still debated. Purpose the purpose of our study is to evaluate the safety and effectiveness of dipyridamole stress echocardiography (DSE) for the detection of CAD in patients undergoing AAA surgery with high cardiovascular risk. Methods From 2017th to 2019th 120 patients underwent surgery for aortic aneurysm (71 endovascular technique and 49 with open laparotomy). Of these, 74 asymptomatic patients with high cardiovascular risk underwent a pre-surgical contrast-enhanced dipyridamole stress echo (0,84 mg/kg over 6 minutes – protocol with LVO with sulfur hexafluoride), to exclude the presence of inducible myocardial ischemia, Mean follow-up was 6-24 months. Results Mean age was 77 years +/- 6.6, with male gender prevalent (83%). No complication during DSE occurred; mean SCORE risk was 9.8% +/- 2.3%, with 63% patients with very high risk. Only 1 patient showed inducible ischemia during stress echocardiography, with evidence of significant LAD stenosis; no myocardial infarction was reported at follow-up, while 1 ischemic stroke and 1 unplanned revascularization occurred. 11% of patients died, of which 50% for Sars-Cov-2 disease and 12% due to post-surgery dissection while no cardiac deaths were found. Conclusions dipyridamole stress echo is safe in patients with surgical-class abdominal aortic aneurism; in patients with high cardiovascular risk but no symptoms reversible ischemia is rare. DSE should not be routinely performed before high-risk surgery but only in patients with cardiac symptoms. Abstract Figure. Patients Diagram ![]()

Abstract
PURPOSE Magnetic Resonance (MR) is recommended to diagnose Intraductal Papillary Mucinous Neoplasms (IPMN) and in the follow-up of borderline lesions. The purpose of this work is to evaluate the diagnostic accuracy of dynamic MR with Diffusion Weighted Imaging (DWI) in the identification of mural nodules of pancreatic IPMN by using pathological analysis as gold standard. MATERIALS AND METHODS Ninety-one preoperative MR with histopathological diagnosis of IPMN were reviewed by two radiologists. Presence, number and size of mural nodule, signal intensity of the nodule on T1-weighted imaging (T1-WI) after contrast medium administration and on DWI. Inter-observer agreement was evaluated. RESULTS Significant correlation (p < 0.0001) were found for presence of nodules > 5 mm on MR and pathological specimen, size and number of mural nodules evaluated on pathological review and degree of dysplasia, size and number of mural nodules evaluated on MR and tumoral dysplasia, presence of nodule > 5 mm with enhancement after contrast medium administration and hyperintensity on DWI and degree of dysplasia. Interobserver agreement was moderate for the presence of mural nodule (K = 0.56), for the presence of high signal intensity on DWI (K = 0.57) and enhancement of mural nodule (K = 0.58). Apparent Diffusion Coefficient (ADC) map histogram analysis showed a correlation between Entropy of the entire cystic lesion and the degree of dysplasia (p < 0.034). CONCLUSIONS MR with dynamic and DWI sequences was an accurate method for the identification of ≥ 5 mm solid nodules of the IPMNs and correlate with the lesion malignancy. Entropy, calculated from the histogram analysis of the IPMN ADC map, correlated with the lesion dysplasia.

Abstract
BACKGROUND Data on the reliability of the Ki-67 index and grading calculations from endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) of pancreatic neuroendocrine tumors (PanNETs) are controversial. We aimed to assess the accuracy of these data compared with histology. METHODS Cytological analysis from EUS-FNA in patients with suspected PanNETs (n = 110) were compared with resection samples at a single institution. A minimum of 2000 cells were considered to be adequate for grading. Correlation and agreement between cytology and histology in grading and Ki-67 values, respectively, were investigated. Secondary outcomes included the diagnostic performance of EUS-FNA. RESULTS EUS-FNA samples were adequate for PanNET diagnosis and PanNET grading in 98/110 (89.1 %) and 77/110 (70.0 %) patients, respectively; thus, 77 samples were adequate for comparing cytology vs. histology. There were 67 (62.0 %), 40 (36.4 %), and 1 (0.9 %) patients with a final diagnosis of G1, G2, and G3 tumors, respectively. EUS-FNA grading was concordant with surgical pathology in 81.8 % of patients; under- and overgrading occurred in 15.6 % and 2.6 %, respectively. The overall level of agreement for grading was moderate (Cohen's κ = 0.59, 95 % confidence interval [CI] 0.34 - 0.78). Spearman's rho for Ki-67 in tumors ≤ 20 mm and > 20 mm was strong and moderate, respectively (rho = 0.68, 95 %CI 0.47 - 0.83; rho = 0.59, 95 %CI 0.35 - 0.75). The Bland - Altman plot showed that the Ki-67 values were comparable and reproducible between the two measurements. CONCLUSIONS Although they were not available for a significant number of patients, grading and Ki-67 values from cytology correlated with histology moderately to strongly.

Abstract
Background: Up-front surgery followed by postoperative chemotherapy remains the standard paradigm for the treatment of patients with resectable pancreatic cancer. However, the risk for positive surgical margins, the poor recovery after surgery that often impairs postoperative treatment, and the common metastatic relapse limit the overall clinical outcomes achieved with this strategy. Polychemotherapeutic combinations are valid options for postoperative treatment in patients with good performance status. liposomal irinotecan (Nal-IRI) is a novel nanoliposome formulation of irinotecan that accumulates in tumor-associated macrophages improving the therapeutic index of irinotecan and has been approved for the treatment of patients with metastatic pancreatic cancer after progression under gemcitabine-based therapy. Thus, it remains of the outmost urgency to investigate introduction of the most novel agents, such as nal-IRI, in perioperative approaches aimed at increasing the long-term effectiveness of surgery. Methods: The nITRO trial is a phase II, single-arm, open-label study to assess the safety and the activity of nal-IRI with fluorouracil/leucovorin (5-FU/LV) and oxaliplatin in the perioperative treatment of patients with resectable pancreatic cancer. The primary tumor must be resectable with no involvement of the major arteries and no involvement or <180° interface between tumor and vessel wall of the major veins. A total of 72 patients will be enrolled to receive a perioperative treatment of three cycles before and three cycles after surgical resection with nal-IRI 50 mg/m2, oxaliplatin 60 mg/m2, leucovorin 200 mg/m2, and 5-fluorouracil 2400 mg/m2, days 1 and 15 of a 28-day cycle. The primary objective is to improve from 40% to 55% the proportion of patients achieving R0 resection after preoperative treatment. Discussion: The nITRO trial will contribute to strengthen the clinical evidence supporting perioperative strategies in resectable pancreatic cancer patients. Moreover, this study represents a unique opportunity for translational analyses aimed to identify novel immune-related prognostic and predictive factors in this setting.

Abstract
Pancreatic malignant exocrine tumors represent the most important cause of cancer-related death for pancreatic neoplasms. The most common tumor type in this category is represented by pancreatic ductal adenocarcinoma (PDAC), an ill defined, stroma-rich, scirrhous neoplasm with glandular differentiation. Here we present the relevant characteristics of the most important PDAC variants, namely adenosquamous carcinoma, colloid carcinoma, undifferentiated carcinoma, undifferentiated carcinoma with osteoclast-like giant cells, signet ring carcinoma, medullary carcinoma and hepatoid carcinoma. The other categories of malignant exocrine tumors, characterized by fleshy, stroma-poor, circumscribed neoplasms, include acinar cell carcinoma (pure and mixed), pancreatoblastoma, and solid pseudopapillary neoplasms. The most important macroscopic, histologic, immunohistochemical and molecular hallmarks of all these tumors, highlighting their key diagnostic/pathological features are presented. Lastly, standardized indications regarding gross sampling and how to compile a formal pathology report for pancreatic malignant exocrine tumors will be provided.

Abstract
Pancreatic neuroendocrine tumors (p-NETs) are a rare group of neoplasms that often present with liver metastases. Histological characteristics, metabolic behavior, and liver tumor burden (LTB) are important prognostic factors. In this study, the usefulness of texture analysis of liver metastases in evaluating the biological aggressiveness of p-NETs was assessed. Fifty-six patients with liver metastases from p-NET were retrospectively enrolled. Qualitative and quantitative CT features of LTB were evaluated. Histogram-derived parameters of liver metastases were calculated and correlated with the tumor grade (G) and 18F-fluorodeoxyglucose (18F-FDG) standardized uptake value (SUV). Arterial relative enhancement was inversely related with G (−0.37, p = 0.006). Different metastatic spread patterns of LTB were not associated with histological grade. Arterialentropy was significantly correlated to G (−0.368, p = 0.038) and to Ki67 percentage (−0.421, p = 0.018). The ROC curve for the Arterialentropy reported an area under the curve (AUC) of 0.736 (95% confidence interval 0.545–0.928, p = 0.035) in the identification of G1–2 tumors. Arterialuniformity values were correlated to G (0.346, p = 0.005) and Ki67 levels (0.383, p = 0.033). Arterialentropy values were directly correlated with the SUV (0.449, p = 0.047) which was inversely correlated with Arterialuniformity (−0.499, p = 0.025). Skewness and kurtosis reported no significant correlations. In conclusion, histogram-derived parameters may predict adverse histological features and metabolic behavior of p-NET liver metastases.

Abstract
BACKGROUND The pattern of nodal spread in body-tail pancreatic ductal adenocarcinoma (PDAC) has been poorly investigated. This study analyzed the characteristics of lymph node (LN) involvement and the prognostic role of nodal metastases stratified by LN stations. METHODS All upfront distal pancreatectomies (DPs) for PDAC (2000-2017) with complete information on station 8,10,11, and 18 were included. Clinico-pathological correlates and survival were investigated using uni- and multivariable analyses. RESULTS Among 100 included patients, 28 were N0, 42 N1 and 30 N2. The median number of examined LN was 32 (IQR 26-44). Tumor size at preoperative imaging increased across N-classes. Preoperative size >27.5 mm was associated with N2 status. The frequency of nodal metastases at stations 8, 9, 10, 11, and 18 was 12.0%, 10.9%, 3.0%, 71.0%, and 19%, respectively. The pattern of LN spread was independent from primary tumor location (with tail tumors metastasizing to station 8/9 and body tumors to station 10), while it was highly associated with N-class. At multivariable analysis, tumor grading, adjuvant treatment, station 9 and 10 metastases were independent prognostic factors in node-positive patients. CONCLUSIONS In patients undergoing upfront DP for PDAC preoperative tumor size is associated with the degree of nodal spread. While station 11 was the most frequently involved, only station-9 and 10 metastases were independent prognostic factors. The site of nodal metastases was somewhat unpredictable based on tumor location. This data has potential implications for allocating patients to neoadjuvant treatment and supports the performance of routine splenectomy during DP for PDAC.

Abstract
BACKGROUND The albumin-bilirubin (ALBI) score is a mathematical model including serum albumin and bilirubin, recently proposed as an alternative prognostic tool in patients with hepatocellular carcinoma (HCC). The aims of this study were to provide evidence that the ALBI score can identify different prognostic groups in Child-Pugh (CP) class A patients undergoing liver resection with curative intent and to verify the ability of the ALBI score to predict short-term and long-term outcomes. METHODS We performed a retrospective analysis on patients classified as class A according to the CP score who underwent liver resection with curative intent for HCC between 2006 and 2016 in the Division of Hepatobiliary Surgery at the University of Verona. Patients were divided according to the ALBI score and the presence or absence of preoperative clinically significant portal hypertension (CSPH). RESULTS Among the 187 CP class A patients, 125 patients (66.8%) were ALBI 1 and 62 patients (33.2%) were ALBI 2. The 5-year overall survival (OS) was 49.2% in the entire cohort and was 57.1% and 33.5% for ALBI 1 and ALBI 2, respectively (P=0.0014). ALBI 2 patients showed a higher rate of post-hepatectomy liver failure (PHLF), 9.7% vs. 2.4% for ALBI 1 (P=0.027). In the multivariate analysis, the ALBI score [hazard ratio (HR) 1.9, P=0.026], stage of fibrosis (HR 2.0, P=0.02) and vascular invasion (HR 3.1, P<0.001) were the independent factors associated with OS. CSPH was identified in 60 (32.1%) patients. Of the patients with CSPH, the 5-year OS was 44.6% and 25.2% for ALBI 1 and ALBI 2, respectively (P=0.031). Of the patients without CSPH, the 5-year OS was 62.5% and 37.6% for ALBI 1 and ALBI 2, respectively (P=0.021). CONCLUSIONS The ALBI score represents a simple tool to stratify the risk of PHLF and OS in CP class A HCC patients undergoing surgery and to evaluate the prognosis in patients with CSPH. This study justifies the use of the ALBI score in clinical practice to better select patients before surgery.

Abstract
To evaluate pancreatic neuroendocrine neoplasms (panNENs) grade prediction by means of qualitative and quantitative CT evaluation, and 3D CT-texture analysis. Patients with histopathologically-proven panNEN, availability of Ki67% values and pre-treatment CT were included. CT images were retrospectively reviewed, and qualitative and quantitative images analysis were done; for quantitative analysis four enhancement-ratios and three permeability-ratios were created. 3D CT-texture imaging analysis was done (Mean Value; Variance; Skewness; Kurtosis; Entropy). Subsequently, these features were compared among the three grading (G) groups. 304 patients affected by panNENs were considered, and 100 patients were included. At qualitative evaluation, frequency of irregular margins was significantly different between tumor G groups. At quantitative evaluation, for all ratios, comparisons resulted statistical significant different between G1 and G3 groups and between G2 and G3 groups. At 3D CT-texture analysis, Kurtosis resulted statistical significant different among three G groups and Entropy resulted statistical significant different between G1 and G3 and between G2 and G3 groups. Quantitative CT evaluation of panNENs can predict tumor grade, discerning G1 from G3 and G2 from G3 tumors. CT-texture analysis can predict panNENs tumor grade, distinguishing G1 from G3 and G2 from G3, and G1 from G2 tumors.

Abstract
BACKGROUND/AIMS Pancreatic neuroendocrine tumors (pan-NENs) represent an increasingly common indication for pancreatic resection, but there are few data regarding possible recurrence after surgery. The aim of the study was to describe the frequency, timing, and patterns of recurrence after resection for pan-NENs with consequent implications for postoperative follow-up. METHODS We performed a retrospective analysis of pan-NENs resected between 1990 and 2015 at The Pancreas Institute, University of Verona Hospital Trust. Predictors of recurrence were assessed. Survival analysis was conducted using the Kaplan-Meier and conditional survival (CS) methods. RESULTS The cohort consisted of 487 patients with a median follow-up of 71 months. Recurrence developed in 12.3%: 54 (11.1%) liver metastases, 11 (2.3%) local recurrence, 10 (2.1%) nodal recurrence, and 8 (1.6%) metastases in other organs. Thirty-one (6.4%) died due to disease recurrence. Size > 21 mm, G3 grade, nodal metastasis, and vascular infiltration were independent predictors of overall recurrence. Recurrence occurred either during the first year of follow-up (n = 9), or after 10 years (n = 4). CS analysis revealed that nonfunctioning G1 pan-NEN ≤20 mm without nodal metastasis or vascular invasion had a negligible risk of developing recurrence. In the present series, after 5 years of follow-up without developing recurrence, tumor recurrence occurred only in the form of liver metastases. CONCLUSIONS Recurrence of pan-NENs is rare and is predicted by tumor size, nodal metastasis, grading, and vascular invasion. Patients with G1 pan-NEN without nodal metastasis and vascular invasion may be considered cured by surgery. After 5 years without recurrence, follow-up should focus on excluding the development of liver metastases.

Abstract
Abstract Pancreatic neuroendocrine neoplasms (P-NENs) are the second most common solid pancreatic neoplasms. P-NENs have a wide range of imaging features presentations and they can be detected with typical and atypical imaging presentations. Typical and atypical appearances can be explained by pathologic correlations. P-NENs are generally hypervascular lesions, showing a typical enhancement behavior after contrast media injection during imaging methods, but they could also have different imaging features, creating some difficulty in differential diagnosis. For this reason, radiologists should be aware of different imaging presentations of these neoplasms. Radiological evaluation has a critical role in P-NENs identification, characterization, and staging of these neoplasms, especially in those cases in which surgery is the treatment of choice. The present paper shows, indicating the underlying pathologic correlations, typical and atypical presentations of NENs. Key Points • P-NENs have a wide range of imaging features presentations, typical and atypical. • Pathology could help in better understanding the typical P-NENs appearance at imaging. • P-NENs are generally hypervascular lesions. • Radiological evaluation has a critical role in P-NENs identification and management. • Radiologists should know every type of different imaging presentation of P-NENs to better diagnose these kinds of lesions.

Abstract
Autoimmune pancreatitis (AIP) is a rare disorder whose association with coeliac disease (CD) has never been investigated, although CD patients display a high prevalence of both endocrine and exocrine pancreatic affections. Therefore, we sought to evaluate the frequency of CD in patients with AIP and in further medical pancreatic disorders. The screening for CD was carried out through the detection of tissue transglutaminase (tTG) autoantibodies in sera of patients retrospectively enrolled and divided in four groups: AIP, chronic pancreatitis, chronic asymptomatic pancreatic hyperenzymemia (CAPH), and control subjects with functional dyspepsia. The search for anti-endomysium autoantibodies was performed in those cases with borderline or positive anti-tTG values. Duodenal biopsy was offered to all cases showing positive results. One patient out of 72 (1.4%) with AIP had already been diagnosed with CD and was following a gluten-free diet, while one case out of 71 (1.4%) with chronic pancreatitis and one out of 92 (1.1%) control subjects were diagnosed with de novo CD. No cases of CD were detected in the CAPH group. By contrast, a high prevalence of cases with ulcerative colitis was found in the AIP group (13.8%). Despite a mutual association between CD and several autoimmune disorders, our data do not support the serologic screening for CD in AIP. Further studies will clarify the usefulness of CD serologic screening in other pancreatic disorders.

Abstract
CD200 has been recently indicated as a robust marker of well-differentiated neuroendocrine neoplasms. Here, we evaluate its role in differential diagnosis of solid pancreatic neoplasms. We immunostained for CD200 22 solid pseudopapillary neoplasms (SPNs), 8 acinar carcinomas (ACs), 2 pancreatoblastomas (PBs), 138 neuroendocrine tumors (PanNETs), and 48 ductal adenocarcinomas. All SPNs showed strong cytoplasmic and membranous staining for CD200, while only one case of AC had focal positivity. The two PBs showed focal CD200 positivity, mainly located in squamoid nests. The vast majority of PanNETs (96%) showed strong cytoplasmic and membranous staining for CD200, whereas all PDACs were negative. As both PanNETs and SPNs express CD200, it has no role in the differential diagnosis between these two entities.

Abstract
BACKGROUND/AIM Re-staging of ductal adenocarcinoma using computed tomography (CT) scan can be problematic so new imaging techniques and evaluation parameters are required. The aim of the study was to evaluate the added value of CT texture analysis in estimation of tissue changes in ductal adenocarcinoma downsized and resected after chemotherapy. MATERIALS AND METHODS Patients with ductal adenocarcinoma downstaged after neoadjuvant treatment, and resected, were included. A pre- and post-treatment CT was obtained. In comparison, patients with disease progression were included for texture analysis evaluation at CT pre- and post-treatment. CT texture analysis results were compared. RESULTS A total of 17 patients affected by un-resectable or borderline ductal adenocarcinoma reached the resectable stage after treatment. The comparison between Kurtosis pre- and Kurtosis post-treatment showed a statistically significant difference. On the contrary, in the comparison group composed of 14 patients with disease progression there was no statistical difference regarding this parameter. CONCLUSION This evaluation may represent an added value in tumor tissue changes judgment and can be extremely useful to diagnose downstaging in those cases with no evident downsizing after chemotherapy.

Abstract
Undifferentiated carcinoma with osteoclast-like giant cells (UCOGC), a variant of pancreatic ductal adenocarcinoma (PDAC), has a striking genetic similarity to PDAC but a significantly improved overall survival. We hypothesize that this difference could be due to the immune response to the tumor, and as such, we investigated the expression of PD-1, PD-L1, and CD163 in a series of UCOGC. To this aim, 27 pancreatic UCOGCs (11 pure and 16 PDAC-associated), 5 extrapancreatic tumors with osteoclast-like giant cells and 10 pancreatic anaplastic carcinomas were immunostained using antibodies against PD-1, PD-L1, and CD163. In pancreatic UCOGCs, PD-L1 was expressed in neoplastic cells of 17 (63%) of 27 cases, more often in cases with an associated PDAC (P = .04). Expression of PD-L1 was associated with poor prognosis, confirmed by multivariate analysis: patients with PD-L1-positive UCOGCs had a risk of all-cause mortality that was 3 times higher than did patients with PD-L1-negative UCOGCs (hazard ratio, 3.397; 95% confidence interval, 1.023-18.375; P = .034). PD-L1 expression on tumor cells was also associated with aberrant P53 expression (P = .035). PD-1 was expressed on rare lymphocytes in 12 UCOGCs (44.4%), mainly located at the tumor periphery. CD163 was expressed on histiocytes, with a diffuse and strong staining pattern in all UCOGCs. Extrapancreatic tumors with osteoclast-like giant cells showed very similar staining patterns for the same proteins. Anaplastic carcinomas have some similarities to UCOGCs, but PD-L1 has no prognostic roles. Our results may have important implications for immunotherapeutic strategies in UCOGCs; these tumors may also represent a model for future therapeutic approaches against PDAC.

Abstract
OBJECTIVES To evaluate MRI derived whole-tumour histogram analysis parameters in predicting pancreatic neuroendocrine neoplasm (panNEN) grade and aggressiveness. METHODS Pre-operative MR of 42 consecutive patients with panNEN >1 cm were retrospectively analysed. T1-/T2-weighted images and ADC maps were analysed. Histogram-derived parameters were compared to histopathological features using the Mann-Whitney U test. Diagnostic accuracy was assessed by ROC-AUC analysis; sensitivity and specificity were assessed for each histogram parameter. RESULTS ADCentropy was significantly higher in G2-3 tumours with ROC-AUC 0.757; sensitivity and specificity were 83.3 % (95 % CI: 61.2-94.5) and 61.1 % (95 % CI: 36.1-81.7). ADCkurtosis was higher in panNENs with vascular involvement, nodal and hepatic metastases (p= .008, .021 and .008; ROC-AUC= 0.820, 0.709 and 0.820); sensitivity and specificity were: 85.7/74.3 % (95 % CI: 42-99.2 /56.4-86.9), 36.8/96.5 % (95 % CI: 17.2-61.4 /76-99.8) and 100/62.8 % (95 % CI: 56.1-100/44.9-78.1). No significant differences between groups were found for other histogram-derived parameters (p >.05). CONCLUSIONS Whole-tumour histogram analysis of ADC maps may be helpful in predicting tumour grade, vascular involvement, nodal and liver metastases in panNENs. ADCentropy and ADCkurtosis are the most accurate parameters for identification of panNENs with malignant behaviour. KEY POINTS • Whole-tumour ADC histogram analysis can predict aggressiveness in pancreatic neuroendocrine neoplasms. • ADC entropy and kurtosis are higher in aggressive tumours. • ADC histogram analysis can quantify tumour diffusion heterogeneity. • Non-invasive quantification of tumour heterogeneity can provide adjunctive information for prognostication.

Abstract
INTRODUCTION Cystic pancreatic neuroendocrine tumors (CPanNETs) represent an uncommon variant of pancreatic neuroendocrine tumors (PanNETs). Due to their rarity, there is a lack of knowledge with regard to clinical features and postoperative outcome. METHODS The prospectively maintained surgical database of a high-volume institution was queried, and 46 resected CPanNETs were detected from 1988 to 2015. Clinical, demographic, and pathological features and survival outcomes of CPanNETs were described and matched with a population of 92 solid PanNETs (SPanNETs) for comparison. RESULTS CPanNETs accounted for 7.8% of the overall number of resected PanNETs (46/587). CPanNETs were mostly sporadic (n = 42, 91%) and nonfunctioning (39%). Two functioning CPanNETs were detected (4.3%), and they were 2 gastrinomas. The median tumor diameter was 30 mm (range 10-120). All tumors were well differentiated, with 38 (82.6%) G1 and 8 (17.4%) G2 tumors. Overall, no CPanNET showed a Ki-67 >5%. A correct preoperative diagnosis of a CPanNET was made in half of the cases. After a median follow-up of >70 months, the 5- and 10-year overall survival of resected CPanNETs was 93.8 and 62.5%, respectively, compared to 92.7 and 84.6% for SPanNETs (p > 0.05). The 5- and 10-year disease-free survival rates were 94.5 and 88.2% for CPanNETs and 81.8 and 78.9% for SPanNETs, respectively (p > 0.05). CONCLUSION In the setting of a surgical cohort, CPanNETs are rare, nonfunctional, and well-differentiated neoplasms. After surgical resection, they share the excellent outcome of their well-differentiated solid counterparts for both survival and recurrence.

Abstract
BACKGROUND Assessment of potential liver allograft donors with frozen sections has clinical relevant consequences for the transplant recipient. Several clinical risk factors have been identified that increase the risk of transplantation failure and it is critical for the pathologist to become familiar with the histologic criteria for donor liver suitability. In this setting an accurate and reliable assessment of fibrosis is crucial. We sought to report the value of the rapid chromotrope aniline blue stain (CAB) in a transplantation clinical work-flow for scoring liver fibrosis. MATERIALS AND METHODS Twenty consecutive intraoperative donor liver biopsy specimens were evaluated by a pathologist at the Transplant Pathology Board Room, AOUI Verona, during 24-hour on-call service. The stage of fibrosis was evaluated according to Ishak score ranging from 0 to 6 (absent to cirrhosis) using hematoxylin and eosin stain (H&E) plus rapid CAB special stain. After a 3-week washout period, only the slides stained with H&E were re-assessed for fibrosis stage by the same pathologist blinded to donor patient data. RESULTS Combination H&E-CAB staging fibrosis score was higher in 20%, lower in 10%, and the same in 70% of biopsy specimens as determined using only H&E stain alone. Rapid CAB stain takes 20 minutes longer than H&E stain alone. CONCLUSIONS CAB staining may be performed on frozen tissue from liver biopsy during a transplantation process without a significant delay in diagnosis. Combination H&E-CAB staining improves sensibility of interpretation of fibrosis.

Abstract
Obturator hernia is a rare entity; delayed diagnosis and treatment are associated with high rate of morbidity. It usually occurs in female and presents with bowel obstruction symptoms such as nausea, vomit and hydroelectrolyte imbalance. Surgery is the unique treatment: both laparoscopic transabdominal or laparotomic approaches are proposed.
Introduction The obturator hernia is a rare pelvic hernia that often comes in the shape of bowel obstruction caused by the presence of an intestinal segment, more often ileum, passing trough the obturator foramen of the pelvic wall (Fig. 1). This type of hernia accounts for 0.5-1.4% of all hernias. Case presentation We report the clinical case of a 84-year-old woman with no previous surgical interventions, who went to the emergency room complaining of vomit and nausea, bowels closed to gas and stool, which she had experienced for three previous days. Routine blood test showed impaired renal function and hydrohelectrolyte imbalance. A CT scan revealed a right ileal, strangulated obturator hernia. The patient underwent an emergency surgical intervention with laparoscopic trans-abdominal peritoneal approach (TAP): after the reduction of the herniated segment, a primary suturing of the parietal defect was performed without ileal resection. Discussion Because of the non-specific symptoms the diagnosis of this kind of hernia is often unclear; female are 6–9 times more likely than men to be subject to the aforementioned pathology, mostly occurring in multiparous, emaciated, elderly woman so it is also called “the little old lady’s hernia”. Risk factors are loss of weight, chronic pulmonary disease and ascites which increase the abdominal pressure. An unfrequent presenting sign is a palpable mass, or the Howship-Romberg sign- a pain radiating from the inner tigh and knee − but it could be misleading when confused with symptoms of gonarthrosis or lumbar vertebral disc pathology. CT scan has superior sensitivity and accuracy with respect to other radiological exams to assess the presence of an obturator hernia. Conclusion Obturator hernia is a rare type of hernia due to his diagnosis, which is often unclear; a prompt suspect based for the non-specific symptoms is crucial for the diagnosis. Surgical management depends on early diagnosis and it is the only possible treatment for this pathology.

Abstract
BACKGROUND Since prognosis and treatment of pancreatic endocrine tumors (pNET) are based on tumor grade, contrast-enhanced multidetector computed tomography (MDCT) features of solid non-functioning pNETs were studied and correlated with pathology tumor grading. METHODS MDCTs of diagnosed pNETs were reviewed retrospectively. Each tumor was analyzed for location, size, homogeneity, margins, arterial and venous phase enhancement, main pancreatic duct diameter, calcifications, vascular invasion, lymph-nodes enlargement, and liver metastases. RESULTS Of 154 pNETs presenting between January 2000 and May 2016 with available histology from resected specimen or biopsy, there were 65 G1, 72 G2 and 17 G3 pNETs. Tumor diameter varied significantly between the three groups. Tumors >20 mm were more frequently malignant and non-homogeneous than smaller tumors. G1 tumors were more commonly hypervascular and G3 tumors more often non-hypervascular in the arterial phase. Arterial phase non-hyperdensity and tumor non-homogeneity had a higher rate of metastatic lesions. Vascular invasion correlated with presence of metastases and histological grade. G3 tumors were all >20 mm (p = 0.007), more often non-hypervascular in the arterial phase (p = 0.0025), and non-hyperdense in the venous phase (p = 0.009), and showed more often vascular invasion (p = 0.0198). CONCLUSION CT correlated with tumor grade; differentiating low-grade and high-grade pNETs through routine CT imaging might improve patient management.

Abstract
Undifferentiated carcinoma of the pancreas with osteoclast-like giant cells (UCOGC) is currently considered a morphologically and clinically distinct variant of pancreatic ductal adenocarcinoma (PDAC). In this study, we report clinical and pathological features of a series of 22 UCOGCs, including the whole exome sequencing of eight UCOGCs. We observed that 60% of the UCOGCs contained a well-defined epithelial component and that patients with pure UCOGC had a significantly better prognosis than did those with an UCOGC with an associated epithelial neoplasm. The genetic alterations in UCOGC are strikingly similar to those known to drive conventional PDAC, including activating mutations in the oncogene KRAS and inactivating mutations in the tumor suppressor genes CDKN2A, TP53, and SMAD4. These results further support the classification of UCOGC as a PDAC variant and suggest that somatic mutations are not the determinants of the unique phenotype of UCOGC.

Abstract
BACKGROUND The outcomes of pancreatectomy with superior mesenteric vein (SMV) or portal vein (PV) resection have been mixed. This study investigated the morbidity and mortality profile after SMV-PV resection in comparison with standard pancreatectomy. Furthermore, we assessed whether tumors with histologically proven SMV-PV infiltration differ from other pT3 neoplasms in terms of recurrence pattern and survival. METHODS All patients with a pT3 head adenocarcinoma resected from 2000 to 2013 were analyzed retrospectively. In the SMV-PV resection group, information on venous wall status was obtained through pathologic reports. Standard statistical methods were used for data analysis. RESULTS The study population consisted of 651 patients, of whom 81 (12.4%) underwent synchronous SMV-PV resection. Venous resection was not associated with a higher rate of postoperative complications (60.5% versus 50.2%) and mortality (1.2% versus 1.1%) in comparison with standard pancreatectomy. Vascular infiltration was confirmed pathologically in 56/81 patients (69.1%). The median disease-specific survival of the entire population was 27 months (95% CI 24.6-29.3), with a 5-year survival rate of 20.5%. The median recurrence-free survival was 18 months (95% CI 15.0-20.9). On multivariate analysis, ASA score, preoperative pain, Ca 19-9 levels, tumor grade, R-status, lymph-vascular invasion, N-status, and adjuvant therapy resulted to be survival predictors. Similarly, Ca 19.9 levels, R-status, and N-status were predictors of recurrence. SMV-PV infiltration was not a significant prognostic factor. CONCLUSION Morbidity and mortality rates of pancreatectomy with SMV-PV resection are comparable with standard pancreatectomy. Pancreatic head adenocarcinoma with histologically confirmed SMV-PV infiltration does not segregate prognostically from other pT3 tumors.

Abstract
AIM To describe the imaging features of serous neoplasms of the pancreas using ultrasound, endoscopic ultrasound, computed tomography and magnetic resonance imaging.
METHODS This multicenter international collaboration enhances a literature review to date, reporting features of 287 histologically confirmed cases of serous pancreatic cystic neoplasms (SPNs).
RESULTS Female predominance is seen with most SPNs presenting asymptomatically in the 5th through 7th decade. Mean lesion size was 38.7 mm, 98% were single, 44.2% cystic, 46% mixed cystic and solid, and 94% hypoechoic on B-mode ultrasound. Vascular patterns and contrast-enhancement profiles are described as hypervascular and hyperenhancing.
CONCLUSION The described ultrasound features can aid differentiation of SPN from other neoplastic lesions under most circumstances.

Abstract
AIMS Somatic mutations in genes encoding chromatin remodellers have been reported recently in several cancer types, including approximately half of cholangiocarcinomas. One of the most commonly mutated chromatin remodellers in cholangiocarcinoma is the Polybromo-1 (PBRM1) gene located on chromosome 3p21, which encodes a subunit of the SWI/SNF complex. The aim of this study was to determine the timing of PBRM1 mutations in biliary carcinogenesis. METHODS AND RESULTS In order to accomplish this goal, we used immunohistochemistry to assess PBRM1 protein expression in a series of precursor lesions and invasive biliary carcinomas. Previous studies have correlated loss of protein expression on immunohistochemistry with inactivating mutations in this tumour suppressor gene. We found that PBRM1 loss occurred in approximately 26% of invasive cancers, but PBRM1 expression was retained in all biliary intra-epithelial neoplasia (BilIN) specimens, including 25 intrahepatic BilINs and 19 gallbladder BilINs. CONCLUSIONS These findings indicate that PBRM1 mutation (and resultant loss of expression) is a late event during biliary carcinogenesis. In addition, we confirm a lack of prognostic significance of PBRM1 status in invasive intrahepatic cholangiocarcinoma. This study provides important insights into the basic mechanisms of chromatin remodelling genes in carcinogenesis.

Abstract
BACKGROUND Recent papers consider surgery as an option for synchronous liver oligometastatic patients [metastatic pancreatic ductal adenocarcinoma (mPDAC)]. In this study, we present our series of resected mPDACs after neoadjuvant chemotherapy (nCT). PATIENTS AND METHODS All patients resected after downstaging of mPDAC were included in this study. Downstaging criteria were disappearance of liver metastasis and a decrease in cancer antigen (CA) 19-9. The type and duration of nCT, last nCT surgery interval, histology, morbidity, and mortality were recorded, and overall survival (OS) and disease-free survival (DFS) were analyzed. RESULTS Overall, 24 of 535 patients (4.5%) observed with mPDAC were included. These patients received gemcitabine alone (5/24), gemcitabine + nanoparticle albumin-bound (nab)-paclitaxel (3/24), and FOLFIRINOX (16/24). Primary tumor size decreased from 31 to 19 mm (p < 0.001), and serum CA19-9 decreased from 596 to 18 U/mL (p < 0.001). In 14/24 patients, the tumor was located in the head. Median interval nCT surgery was 2 months, there were no mortalities, and the postoperative course was uneventful in 34% of cases. Grade B/C pancreatic fistula, postoperative bleeding, and sepsis occurred in 17/4, 4, and 12% of cases, respectively, and reoperation rate was 4%. R0 resection was achieved in 88% of cases, with 17% complete pathological response. Positive nodes were found in 9/24 patients with a median node ratio of 0.37, and OS and DFS was 56 and 27 months, respectively. CONCLUSIONS Patients with mPDAC who were fully responsive to nCT may be cautiously considered for surgery, with potential benefit in survival compared with palliative chemotherapy alone. This is supported by results of our retrospective study, which is the largest ever reported.

Abstract
AIM To establish the ability of magnetic resonance (MR) and computer tomography (CT) to predict pathologic dimensions of pancreatic neuroendocrine tumors (PanNET) in a caseload of a tertiary referral center.
METHODS Patients submitted to surgery for PanNET at the Surgical Unit of the Pancreas Institute with at least 1 preoperative imaging examination (MR or CT scan) from January 2005 to December 2015 were included and data retrospectively collected. Exclusion criteria were: multifocal lesions, genetic syndromes, microadenomas or mixed tumors, metastatic disease and neoadjuvant therapy. Bland-Altman (BA) and Mountain-Plot (MP) statistics were used to compare size measured by each modality with the pathology size. Passing-Bablok (PB) regression analysis was used to check the agreement between MR and CT.
RESULTS Our study population consisted of 292 patients. Seventy-nine (27.1%) were functioning PanNET. The mean biases were 0.17 ± 7.99 mm, 1 ± 8.51 mm and 0.23 ± 9 mm, 1.2 ± 9.8 mm for MR and CT, considering the overall population and the subgroup of non-functioning- PanNET, respectively. Limits of agreement (LOA) included the vast majority of observations, indicating a good agreement between imaging and pathology. The MP further confirmed this finding and showed that the two methods are unbiased with respect to each other. Considering ≤ 2 cm non-functioning-PanNET, no statistical significance was found in the size estimation rate of MR and CT (P = 0.433). PBR analysis did not reveal significant differences between MR, CT and pathology.
CONCLUSION MR and CT scan are accurate and interchangeable imaging techniques in predicting pathologic dimensions of PanNET.

Abstract
The diagnosis of pancreatic neuroendocrine tumours (PanNETs) is increasing owing to more sensitive detection methods, and this increase is creating challenges for clinical management. We performed whole-genome sequencing of 102 primary PanNETs and defined the genomic events that characterize their pathogenesis. Here we describe the mutational signatures they harbour, including a deficiency in G:C > T:A base excision repair due to inactivation of MUTYH, which encodes a DNA glycosylase. Clinically sporadic PanNETs contain a larger-than-expected proportion of germline mutations, including previously unreported mutations in the DNA repair genes MUTYH, CHEK2 and BRCA2. Together with mutations in MEN1 and VHL, these mutations occur in 17% of patients. Somatic mutations, including point mutations and gene fusions, were commonly found in genes involved in four main pathways: chromatin remodelling, DNA damage repair, activation of mTOR signalling (including previously undescribed EWSR1 gene fusions), and telomere maintenance. In addition, our gene expression analyses identified a subgroup of tumours associated with hypoxia and HIF signalling.

Abstract
AIM To describe magnetic resonance (MR) imaging features of pancreatic neuroendocrine neoplasms (PanNENs) according to their grade and tumor-nodes-metastases stage by comparing them to histopathology and to determine the accuracy of MR imaging features in predicting their biological behavior.
METHODS This study was approved by our institutional review board; requirement for informed patient consent was waived due to the retrospective nature of the study. Preoperative MR examinations of 55 PanNEN patients (29 men, 26 women; mean age of 57.6 years, range 21-83 years) performed between June 2013 and December 2015 were reviewed. Qualitative and quantitative features were compared between tumor grades and stages determined by histopathological analysis.
RESULTS Ill defined margins were more common in G2-3 and stage III-IV PanNENs than in G1 and low-stage tumors (P < 0.001); this feature had high specificity in the identification of G2-3 and stage III-IV tumors (90.3% and 96%, 95%CI: 73.1-97.5 and 77.7-99.8). The mean apparent diffusion coefficient value was significantly lower in G2-3 and stage III-IV lesions compared to well differentiated and low-stage tumors (1.09 × 10-3 mm2/s vs 1.45 × 10-3 mm2/s and 1.10 × 10-3 mm2/s vs 1.53 × 10-3 mm2/s, P = 0.003 and 0.001). Receiving operator characteristic analysis determined optimal cut-offs of 1.21 and 1.28 × 10-3 mm2/s for the identification of G2-3 and stage III-IV tumors, with sensitivity and specificity values of 70.8/80.7% and 64.5/64% (95%CI: 48.7-86.6/60-92.7 and 45.4-80.2/42.6-81.3).
CONCLUSION MR features of PanNENs vary according to their grade of differentiation and their stage at diagnosis and could predict the biological behavior of these tumors.

Abstract
BACKGROUND We compared the prognostic performance of the International Union Against Cancer/American Joint Committee on Cancer (UICC/AJCC) 7th edition pN stage, number of metastatic LNs (MLNs), LN ratio (LNR), and log odds of MLNs (LODDS) in patients with perihilar cholangiocarcinoma (PCC) undergoing curative surgery in order to identify the best LN staging method. METHODS Ninety-nine patients who underwent surgery with curative intent for PCC in a single tertiary hepatobiliary referral center were included in the study. Two approaches were used to evaluate and compare the predictive power of the different LN staging methods: one based on the estimation of variable importance with prediction error rate and the other based on the calculation of the receiver operating characteristic (ROC) curve. RESULTS LN dissection was performed in 92 (92.9%) patients; 49 were UICC/AJCC pN0 (49.5%), 33 pN1 (33.3%), and 10 pN2 (10.1%). The median number of LNs retrieved was 8. The prediction error rate ranged from 42.7% for LODDS to 47.1% for UICC/AJCC pN stage. Moreover, LODDS was the variable with the highest area under the ROC curve (AUC) for prediction of 3-year survival (AUC = 0.71), followed by LNR (AUC = 0.60), number of MLNs (AUC = 0.59), and UICC/AJCC pN stage (AUC = 0.54). CONCLUSIONS The number of MLNs, LNR, and LODDS appear to better predict survival than the UICC/AJCC pN stage in patients undergoing curative surgery for PCC. Moreover, LODDS seems to be the most accurate and predictive LN staging method.

Abstract
OBJECTIVES Ga-DOTATOC (Ga) positron emission tomography (PET)/computed tomography (CT) is recommended in the workup of pancreas neuroendocrine tumors (PanNETs); evidence suggests that F-FDG (F) PET/CT can also provide prognostic information. Aims of this study were to assess the role of combined Ga- and F-PET/CT in the evaluation of grade (G) 1-2 PanNETs and to test the correlation between F-PET/CT positivity and tumor grade. METHODS Preoperative Ga- and F-PET/CT of 35 patients with surgically resected G1-2 PanNETs were evaluated. For grading, the 2010 World Health Organization Classification was used; an ancillary analysis with Ki67 cutoffs at 5% to 20% was conducted. Correlation between F-PET/CT positivity (SUVmax > 3.5) and grade was assessed. RESULTS Of 35 PanNETs, 28.6% and 71.4% were G1 and G2 as per World Health Organization. Ga-PET/CT showed high sensitivity (94.3%) in detecting G1-2 PanNETs. F-PET/CT was positive in 20% and 76% G1 and G2 tumors (P = 0.002). F-PET/CT identified G2 PanNETs with high positive predictive value (PPV, 90.5%). F-PET/CT correlated with tumor grade also in the ancillary analysis (P = 0.009). CONCLUSIONS The high sensitivity of Ga-PET/CT in NET detection is known. The high PPV of F-PET/CT in the identification of G2 forms suggests its potential role in PanNETs prognostication and risk stratification.

Abstract
Loss of the tumor suppressor gene AT-rich interactive domain-containing protein 1A (ARID1A) has been demonstrated in several cancers, but its prognostic role is unknown. We aimed to investigate the risk associated with loss of ARID1A (ARID1A−) for all-cause mortality, cancer-specific mortality and recurrence of disease in subjects with cancer. PubMed and SCOPUS search from database inception until 01/31/2015 without language restriction was conducted, contacting authors for unpublished data. Eligible were prospective studies reporting data on prognostic parameters in subjects with cancer, comparing participants with presence of ARID1A (ARID1A+) vs. ARID1A−, assessed either via immunohistochemistry (loss of expression) or with genetic testing (presence of mutation). Data were summarized using risk ratios (RR) for number of deaths/recurrences and hazard ratios (HR) for time-dependent risk related to ARID1A− adjusted for potential confounders. Of 136 hits, 25 studies with 5,651 participants (28 cohorts; ARID1A−: n = 1,701; ARID1A+: n = 3,950), with a mean follow-up period of 4.7 ± 1.8 years, were meta-analyzed. Compared to ARID1A+, ARID1A− significantly increased cancer-specific mortality (studies = 3; RR = 1.55, 95% confidence interval (CI) = 1.19–2.00, I2 = 31%). Using HRs adjusted for potential confounders, ARID1A− was associated with a greater risk of cancer-specific mortality (studies = 2; HR = 2.55, 95%CI = 1.19–5.45, I2 = 19%) and cancer recurrence (studies = 10; HR = 1.93, 95%CI = 1.22–3.05, I2 = 76%). On the basis of these results, we have demonstrated that loss of ARID1A shortened time to cancer-specific mortality, and to recurrence of cancer when adjusting for potential confounders. For its role, this gene should be considered as an important potential target for personalized medicine in cancer treatment.

Abstract
Pancreatic cancer represents the seventh leading cause of cancer death in the world, responsible for more than 300,000 deaths per year. The most common tumor type among pancreatic cancers is pancreatic ductal adenocarcinoma, an infiltrating neoplasm with glandular differentiation that is derived from pancreatic ductal tree. Here we present and discuss the most important macroscopic, microscopic, and immunohistochemical characteristics of this tumor, highlighting its key diagnostic features. Furthermore, we present the classic features of the most common variants of pancreatic ductal adenocarcinoma. Last, we summarize the prognostic landscape of this highly malignant tumor and its variants.

Abstract
INTRODUCTION The extranodal extension (ENE) of nodal metastases (the extension of neoplastic cells through the nodal capsule into the perinodal soft tissue) is a histological feature that has been considered a prognostic factor in several cancers, but the role in gastric cancer was not yet investigated. We aimed to investigate the prognostic role of ENE in patients affected by gastric cancer through a systematic review and meta-analysis. MATERIAL AND METHODS Two independent authors searched major databases until 09/30/2015 to identify studies providing data on gastric cancer patients' prognostic parameters and comparing patients with ENE (ENE+) vs intra-nodal extension (ENE-). The data were summarized using risk ratios (RRs) for the number of deaths/recurrences and hazard ratios (HRs) with 95 % confidence intervals (CI), adjusted for potential confounders. RESULTS Nine studies followed up 3250 patients with gastric cancer (1064 ENE+ and 2186 ENE-). ENE+ was associated with a significantly higher risk of all-cause mortality (RR = 1.70; 95 % CI: 1.43-2.03, I (2) = 66 %; HR = 2.14; 95 % CI: 1.66-2.75, I (2) = 0 %), cancer-specific mortality (RR = 1.59; 95 % CI: 1.42-1.79; HR = 1.52; 95 % CI: 1.19-1.96), and disease recurrence (RR = 3.43, 95 % CI: 1.80-6.54, I (2) = 0 %). DISCUSSION Judging from our results, ENE in gastric cancer patients should be considered for prognostic purposes from the gross sample to the pathology report.

Abstract
BACKGROUND Since their introduction in the WHO classification, the incidence of solid pseudopapillary tumors (SPTs) of the pancreas has progressively increased, mainly because of the widespread use of cross-sectional imaging. Few recent studies have analyzed the biological behavior of SPTs, but reliable data on long-term follow-up are needed. METHODS Retrospective analysis of two Institutions with high caseload, The Department of General Surgery-Pancreas Institute, University of Verona Hospital Trust and the Department of General Surgery, Massachusetts General Hospital, Harvard Medical School, was carried out. Data from 131 consecutive resections for SPT performed during the last three decades were collected and analyzed. RESULTS The majority of patients were female (86.3%) with a median age of 33 (7-68) years. The prevalent location was the pancreatic tail (33.5%). Applying the WHO criteria, 16 (12.2%) SPTs were considered malignant due to the presence of at least pancreatic parenchyma (9.9%), perineural (4.6%), and/or angiovascular invasion (2.3%). After a median of 62 months after surgery, only two patients had a recurrence (1.5%). Both of them fulfilled the WHO criteria for malignant SPT (vs. 10.7% of those who did not recur, P = 0.01), had an infiltrative growth pattern (vs. 10.8%, P = 0.01), pancreatic parenchyma invasion (vs. 9.7%, P = 0.01) and capsular invasion (vs. 4.9%, P = 0.004). CONCLUSION Overall, SPTs are associated with excellent survival results after surgical resection. Disease recurrence is extremely rare, and might occur if the primary tumor presents with either pancreatic parenchyma or capsule invasion. J. Surg.

Abstract
Biallelic inactivation of the tumor suppressor gene BRCA1-associated protein 1 (BAP1) has been demonstrated in several cancers, but its prognostic role has not been completely explained. We aimed to investigate the risk associated with loss of BAP1 (BAP1-) for all-cause mortality, cancer-specific mortality and recurrence of disease in subjects with cancer. PubMed and SCOPUS were searched from database inception until 09/15/2015 without language restrictions. Prospective studies reporting data on prognostic parameters in subjects with cancer, comparing participants with presence of BAP1 (BAP1+) vs. BAP1- were included. Data were summarized using risk ratios (RR) for number of deaths/recurrences and hazard ratios (HR) for time-dependent risk related to BAP1- adjusted for potential confounders. From 261 hits, 12 studies (including 13 cohorts) with 3,447 participants (BAP1-: n = 697; BAP1+: n = 2,750), with a median follow-up over 60 months, were meta-analyzed. Compared to BAP1+, BAP1- significantly increased all-cause mortality, cancer-specific mortality and risk of recurrence in all the tumor types analyzed, except for mesothelioma, in which the presence of BAP1 mutations correlates with a better prognosis. Furthermore, we demonstrated that BAP1 mutated colorectal and renal carcinomas are associated with high-tumor grading (P < 0.0001), and that BAP1 mutated is more common in women than in men (P < 0.0001). In conclusion, on the basis of our meta-analysis, we have demonstrated a peculiar role of BAP1 in influencing the prognosis in cancer. Thus, BAP1 could be considered as an important potential target for personalized medicine. © 2016 Wiley Periodicals, Inc.
