Abstract
Introduction Pancreatic ductal adenocarcinoma (PDAC) is lethal due to its late diagnosis and lack of successful treatments. A possible strategy to reduce its death burden is prevention. Intraductal papillary mucinous neoplasms (IPMNs) are precursors of PDAC. It is difficult to estimate the incidence of IPMNs because they are asymptomatic. Two recent studies reported pancreatic cysts in 3% and 13% of scanned subjects. The possibility of identifying a subgroup of IPMN patients with a higher probability of progression into cancer could be instrumental in increasing the survival rate. In this study, genetic and non-genetic PDAC risk factors were tested in a group of IPMN patients under surveillance. Methods A retrospective study was conducted on 354 IPMN patients enrolled in two Italian centres with an average follow-up of 64 months. With the use of DNA extracted from blood, collected at IPMN diagnosis, all patients were genotyped for 30 known PDAC risk loci. The polymorphisms were analysed individually and grouped in an unweighted polygenic score (PGS) in relation to IPMN progression. The ABO blood group and non-genetic PDAC risk factors were also analysed. IPMN progression was defined based on the development of worrisome features and/or high-risk stigmata during follow-up. Results Two genetic variants (rs1517037 and rs10094872) showed suggestive associations with an increment of IPMN progression. After correction for multiple testing, using the Bonferroni correction, none of the variants showed a statistically significant association. However, associations were observed for the non-genetic variables, such as smoking status, comparing heavy smokers with light smokers (HR = 3.81, 95% 1.43-10.09, p = 0.007), and obesity (HR = 2.46, 95% CI 1.22-4.95, p = 0.012). Conclusion In conclusion, this study is the first attempt to investigate the presence of shared genetic background between PDAC risk and IPMN progression; however, the results suggest that the 30 established PDAC susceptibility polymorphisms are not associated with clinical IPMN progression in a sample of 354 patients. However, we observed indications of cigarette smoking and body mass index (BMI) involvement in IPMN progression. The biological mechanism that could link these two risk factors to progression could be chronic inflammation, of which both smoking and obesity are strong promoters.

Abstract
BACKGROUND Serial imaging in patients with aortic aneurysms may identify non-vascular disease. However, the prevalence and clinical history of pancreatic incidentalomas in this population is unknown. METHODS Retrospective cross-sectional study of adults who underwent computed tomography angiography (CTA) surveillance imaging for abdominal or thoracoabdominal aortic aneurysm at a single academic institution between 2015 and 2020. Descriptive statistics were used for patients with pancreatic lesions. RESULTS Of 249 patients, 18 (7.2 %) had a pancreatic incidentaloma. Compared to patients without a lesion, those with a lesion were more likely female (50.0 % vs 24.2 %, p = 0.02) and less likely a smoker (72.2 % vs 90.0 %, p = 0.02). 3 patients with pancreatic lesions underwent intervention, and 1 patient received additional imaging. 2 patients had a surgical oncology referral. CONCLUSIONS Pancreatic incidentalomas are common in patients with aortic aneurysm, but lesion characteristics and management vary. Results suggest that a multi-disciplinary approach, thorough documentation, and referral to pancreatic specialists may be warranted.

Abstract
Background: Several guidelines for the management of cystic pancreatic lesions (CPL) exists. From 2013, Oslo University Hospital adapted the European consensus guidelines (ECG) in the decision-making as to whether patients should be advised to have resection or observation for CPL. The aims of the study were to assess changes over time in the workup and diagnostic accuracy of resected CPL, and the short-term surgical outcome. Methods: Preoperative radiological workup, clinicopathological characteristics, and perioperative outcomes were retrospectively reviewed in three consecutive time periods (early: 2004-2008, intermediate: 2009-2012, late: 2013-2016). The rate of concordance between the ECG recommendations for resection (ECG+) or observation (ECG-) and the final histological diagnosis were assessed. Results: A total of 322 consecutive patients underwent resection for CPL (early: n = 89, intermediate: n = 108, late: n = 125). The most common diagnoses were intraductal papillary mucinous neoplasia (IPMN, 36.0%), serous cystic neoplasm (SCN, 23.9%), mucinous cystic neoplasm (10.6%), pseudocyst (9.6%), solid pseudopapillary neoplasm (7.8%), and cystic pancreatic neuroendocrine tumour (5.3%). The proportion of ECG+ CPL undergoing surgery increased significantly (42.7% vs. 60.7% vs. 70.4%, p < .001). The relative proportion of patients undergoing resection for SCN decreased (38.2% vs. 21.3% vs. 16.0%), whereas it increased for IPMN (31.5% vs. 30.6% vs. 44.0%). The use of magnetic resonance imaging and endoscopic ultrasound increased. There were no differences in postoperative severe complications (23.0% vs. 23.6%) or 90-day mortality (2.3% vs. 0.8%) between ECG+ and ECG- patients. Conclusion: Several changes in the management of CPL were revealed during time. Adherence to guidelines is important in order to avoid unnecessary surgery for CPL.

Decision-Making for the Management of Cystic Lesions of the Pancreas: How Satisfied Are Patients with Surgery? J Gastrointest Surg 2018; 22:88-97. [PMID: 28875275 DOI: 10.1007/s11605-017-3564-1] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/07/2017] [Accepted: 08/24/2017] [Indexed: 01/31/2023]
Abstract
INTRODUCTION This study aims to understand patients' perspectives and satisfaction with choosing surgery for the treatment of pancreatic cystic lesions (PCLs). METHODS A 62-question survey was administered to 113 patients who had a resection for a PCL by 12 surgeons at two pancreatic specialty centers (2004-2016). Patients' final diagnoses and perioperative outcomes were correlated to the survey's results using univariate analysis. RESULTS Fear of cancer was quite or extremely important in most respondents' decision to have surgery (95.4%). Respondents were quite or fully satisfied with the outcomes of surgery (91.1%) and with the decision-making process (89.3%). Distress from anxiety about the cyst before surgery (58.6%) largely outweighed that from postsurgical lifestyle changes (14.4%). Furthermore, 88.7% of patients with pathologically non-malignant disease were quite or fully satisfied with their decision to have surgery, and patients with mucinous neoplasms reported high satisfaction rates independent of grade of dysplasia or malignancy (p = 0.641). CONCLUSION Patients with a resected PCL are highly satisfied with their decision to have surgery, regardless of the final diagnosis or clinical outcome. Fear of cancer is the main driver in the decision-making process, and the anxiety of harboring a cyst is a greater cause of distress than are postsurgical lifestyle changes.

Abstract
Chronic pancreatitis and incidentally discovered pancreatic lesions present significant diagnostic and therapeutic challenges for surgeons. While both decompressive and resection procedures have been described for treatment of chronic pancreatitis, optimal management must be tailored to each patient's individual disease characteristics, parenchymal morphology, and ductal anatomy. Surgeons should strive to achieve long-lasting pain relief while preserving native pancreatic function. For patients with incidentally discovered pancreatic lesions, differentiating benign, pre-malignant, and malignant lesions is critical as earlier treatment is thought to result in improved survival. The purpose of this evidence-based manuscript is to review the presentation, workup, surgical management, and associated outcomes for patients with chronic pancreatitis or incidentally discovered solid and cystic lesions of the pancreas.

Abstract
PURPOSE To compare diagnostic performance for prediction of malignant potential in IPMNs between EUS, contrast-enhanced CT and MRI. MATERIALS AND METHODS 76 patients with IPMN (benign = 37, malignant = 39) underwent EUS, contrast-enhanced CT, and MRI. EUS was analyzed based on formal reports and contrast-enhanced CT and MRI were retrospectively analyzed by two radiologists according to the consensus guidelines 2012. Diagnostic performance and imaging features of malignant IPMNs were analyzed using ROC analysis and multivariate analyses. RESULTS Diagnostic performance of contrast-enhanced CT (AUC = 0.792 in R1, 0.830 in R2), MRI (AUC = 0.742 in R1, 0.776 in R2), and EUS (AUC = 0.733) for predicting malignant IPMNs were comparable without significant difference (p > 0.05). In multivariable analysis, enhancing solid component in contrast-enhanced CT and MRI and mural nodule in EUS (OR 1.8 in CT, 1.36 in MRI, 1.47 in EUS), MPD diameter ≥ 10 mm (OR 1.3 in CT, 1.4 in MRI, 1.66 in EUS), MPD diameter of 5-9 mm (OR 1.23 in CT, 1.31 in MRI), and thickened septa or wall (OR 1.3 in CT and MRI) were significant variables (p < 0.05). Interobserver agreement of thickened cyst septa or wall (k = 0.579-0.617) and abrupt caliber change of MPD (k = 0.689-0.788) was lower than other variables (k > 0.80). CONCLUSION Diagnostic performance of contrast-enhanced CT, MRI, and EUS for predicting malignant IPMNs was comparable with each modalities without significant difference.

Abstract
OBJECTIVE To evaluate the current guidelines as a model to predict malignancy and to determine further radiological predictors of malignancy in intraductal papillary mucinous neoplasms (IPMNs). METHODS 384 patients who had undergone a pancreatic operation with the pathological diagnosis of IPMN as well as applicable pre-operative imaging (CT/MRI) were included in the study. Images were evaluated retrospectively in consensus by two radiologists, using a standardized checklist. Descriptive statistics, binary logistic regression and receiver operator curve analysis were performed to assess the International Consensus Guidelines and other radiological predictors of clinical malignancy (defined as carcinoma in situ and invasive carcinoma). RESULTS The best independent predictors of malignancy (n = 191) were solid components [odds ratio (OR) 3.98], parenchymal atrophy with main pancreatic duct dilation 5-9 mm (OR: 5.1) and common bile duct (CBD) dilation (OR: 31.26). >96% of all cases with CBD dilation were malignant IPMNs (positive-predictive value 96.4%; negative-predictive value 63.1%). Analysis of the current guidelines showed a diagnostic improvement with the addition of CBD dilation on determining the malignancy of IPMNs (sensitivity 82.2%/86.9%; specificity 72.7%/74.6%). Subanalysis of branch duct intraductal papillary mucinous neoplasms (BD-IPMNs; n = 168) also resulted in a diagnostic improvement with the addition of CBD dilation (sensitivity 28.6%/45.2%; specificity 92.9%/92.1%). The best independent predictors of malignancy for BD-IPMNs were parenchymal atrophy (OR: 4.00) and CBD dilation (OR: 29.3). Frequency analysis revealed that even small BD-IPMNs had already undergone malignant transformation (≤1 cm: 15%; 1-2 cm: 26%; 2-3 cm: 20%) with about 10% of those having a dilated bile duct. CONCLUSION CBD dilation was a significant positive predictor of malignancy in IPMNs regardless of their size. ADVANCES IN KNOWLEDGE Introduction of CBD dilation as a radiological predictor for malignancy might increase the diagnostic accuracy of current imaging-based guidelines.

Abstract
International experts met to discuss recent advances and to revise the 2004 recommendations for assessing and reporting precursor lesions to invasive carcinomas of the pancreas, including pancreatic intraepithelial neoplasia (PanIN), intraductal papillary mucinous neoplasm (IPMN), mucinous cystic neoplasm, and other lesions. Consensus recommendations include the following: (1) To improve concordance and to align with practical consequences, a 2-tiered system (low vs. high grade) is proposed for all precursor lesions, with the provision that the current PanIN-2 and neoplasms with intermediate-grade dysplasia now be categorized as low grade. Thus, "high-grade dysplasia" is to be reserved for only the uppermost end of the spectrum ("carcinoma in situ"-type lesions). (2) Current data indicate that PanIN of any grade at a margin of a resected pancreas with invasive carcinoma does not have prognostic implications; the clinical significance of dysplasia at a margin in a resected pancreas with IPMN lacking invasive carcinoma remains to be determined. (3) Intraductal lesions 0.5 to 1 cm can be either large PanINs or small IPMNs. The term "incipient IPMN" should be reserved for lesions in this size with intestinal or oncocytic papillae or GNAS mutations. (4) Measurement of the distance between an IPMN and invasive carcinoma and sampling of intervening tissue are recommended to assess concomitant versus associated status. Conceptually, concomitant invasive carcinoma (in contrast with the "associated" group) ought to be genetically distinct from an IPMN elsewhere in the gland. (5) "Intraductal spread of invasive carcinoma" (aka, "colonization") is recommended to describe lesions of invasive carcinoma invading back into and extending along the ductal system, which may morphologically mimic high-grade PanIN or even IPMN. (6) "Simple mucinous cyst" is recommended to describe cysts >1 cm having gastric-type flat mucinous lining at most minimal atypia without ovarian-type stroma to distinguish them from IPMN. (7) Human lesions resembling the acinar to ductal metaplasia and atypical flat lesions of genetically engineered mouse models exist and may reflect an alternate pathway of carcinogenesis; however, their biological significance requires further study. These revised recommendations are expected to improve our management and understanding of precursor lesions in the pancreas.

Abstract
The development of curvilinear EUS has enabled EUS-guided fine-needle aspiration of intra-abdominal mass lesions. With the introduction of interventional EUS, this technology has undergone several modifications in order to be applied to clinical medicine. One of the potential uses of interventional EUS is the EUS-guided local therapy of pancreatic tumors. Various treatment modalities such as fine-needle injection, radiofrequency ablation, photodynamic therapy, laser ablation, and brachytherapy have been tried under EUS guidance. Some of these modalities are being applied clinically. These methods for EUS-guided local therapy of pancreatic tumors will be reviewed in this article.

Abstract
Intraductal papillary mucinous neoplasms (IPMNs) represent a spectrum of neoplasms arising from the main pancreatic duct or branch ducts and producing mucin and can be regarded as a type of precancerous lesions. Thanks to improvements in endoscopy and imaging techniques, IPMNs are being diagnosed with increasing frequency. However, there are currently no highly sensitive and specific preoperative criteria available to distinguish benign IPMNs from malignant ones. What's more, the necessity for EUS and ERCP in the diagnosis of IPMNs is still under debate. Here, we review recent advances in research of IPMNs and summarize potential differences between benign and malignant IPMNs.

Abstract
Intraductal papillary mucinous neoplasm (IPMN) is a disease in evolution. Since its first description almost 30 years ago, a better understanding of the disease has steadily accrued. Yet, there are numerous challenges still for clinicians who treat this fascinating disease. A group of leading content experts on IPMN was assembled and charged with presenting cutting-edge knowledge on various topics for which they have considerable experience. This manuscript provides an historical perspective of both clinical and biological quandaries that have been resolved to date. Furthermore, it poses new avenues for investigation while highlighting the contributions of the various authors to this collective review.
