Abstract
INTRODUCTION Telecytopathology for endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) has been shown to be an alternative to rapid on-site evaluation (ROSE). Gastroenterologists (endosonographers) performing EUS-FNA can be trained to evaluate a specimen for adequacy. This study examined the ability of an endosonographer with focused cytopathologic training to assess the adequacy of pancreatic FNA specimens and transmit diagnostic images to a remotely located cytopathologist as compared to an experienced cytotechnologist. MATERIALS AND METHODS This was a retrospective study of consecutive pancreatic lesions sampled by EUS-FNA reviewed by an endosonographer and a cytotechnologist. The participants were assessed based on their ability to (1) determine adequacy, (2) locate and transmit representative cell groups, (3) provide a preliminary diagnosis, and (4) provide concordance with actual diagnosis. RESULTS 105 consecutive cases of EUS-FNA of the pancreas were analyzed, including: adenocarcinoma (n = 39), cyst (n = 17), neuroendocrine neoplasia (n = 7), pancreatitis (n = 14), benign pancreas (n = 9), other neoplasms (n = 6), suspicious/atypical (n = 3), and nondiagnostic (n = 10). The cytotechnologist demonstrated superiority in accuracy 92.7% versus 70% (P = 0.003) and subcategorization 95.0% versus 76% (P = 0.007). There was no difference in "broad" categorization (benign/malignant) between the endosonographer and cytotechnologist, 98% and 98.2% (P = 0.946), respectively. Also, there was no difference with regard to adequacy assessment (P = 0.29). A steady learning curve for the endosonographer was demonstrated in their cytologic assessment (P = 0.041). The endosonographer was shown to be able to remotely transmit diagnostic images to a pathologist. CONCLUSION An endosonographer with limited training can examine for specimen adequacy, transmit images, and demonstrate representative cell groups. Larger studies are required though preliminary results are encouraging.

Abstract
Significant advances have been made in the last few years in the technologies for sampling pancreatic masses, and in the understanding of the biology of pancreatic cancer. Better and more targeted treatments are likely to become available. Because most pancreatic cancers are likely to remain unresectable at diagnosis, high-quality, high-cellularity specimens are essential. A tailored approach that considers indication, location, and treatment possibilities needs to be taken before embarking on a pancreatic biopsy. Because the demand from oncologists and patients for increasingly personalized therapy is likely to grow, optimal sampling beyond diagnostic accuracy is likely to become increasingly critical.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is aggressive and lethal with the majority of cases presenting with advanced unresectable disease due to delayed diagnosis. Despite improvement in surgery, chemotherapies, and intensive care medicine, the outcome of PDAC remains poor, which may relate to the tumor biology. Recent data suggest that PDAC is a "systemic cancer" with complex molecular or genomics derangement with marked heterogeneity. The ability to characterize the PDAC better by detailed evaluation of tissue biomarkers or genomics allows for improved prediction of prognosis and stratification of treatment, a concept known as "personalized cancer therapy." Using tissue from resected PDAC specimens has several weaknesses and is only possible in 20% of patients with PDAC. Endoscopic ultrasound (EUS)-guided biopsy overcomes these weaknesses, and with recent advancements in needle technology, tissue can be obtained for personalized cancer therapy for all patients with PDAC. This review aims to outline our current understanding of the molecular biology of PDAC specifically focusing on how EUS-guided biopsy may play a fundamental role in tissue acquisition, allowing for assessment and stratify therapy according to the individual cancer biology as we move toward the era of precision medicine.

Abstract
BACKGROUND Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has become a crucial diagnostic technique for pancreatic malignancies. The specimen obtained by EUS-FNA can be prepared for either cytological or histological examinations. This study was to compare diagnostic performance of cytological and histological preparations using EUS-FNA in the same lesions when pancreatic malignancies were suspected. METHODS One hundred and eighteen patients who underwent EUS-FNA for suspected pancreatic malignancies were consecutively enrolled. All procedures were conducted by a single echoendoscopist under the same conditions. Four adequate preparations were obtained by 22-gauge needles with 20 to-and-fro movements for each pass. The 4 preparations included 2 cytological and 2 histological specimens. The pathologic reviews of all specimens were conducted independently by a single experienced cytopathologist. Sensitivity, specificity, and accuracy of the 2 preparations were compared. RESULTS The enrolled patients consisted of 62 males (52.5%), with the mean age of 64.6±10.5 years. Surgery was performed in 23 (19.5%) patients. One hundred and sixteen (98.3%) lesions were classified as malignant, while 2 (1.7%) were benign. Sensitivity of cytology and histology were 87.9% and 81.9%, respectively, with no significant difference (P=0.190). Accuracy was also not significantly different. Cytological preparation was more sensitive when the size of lesion was <3 cm (86.7% vs 68.9%, P=0.033). CONCLUSIONS Our results suggested that the diagnostic performances of cytological and histological preparations are not significantly different for the diagnosis of pancreatic malignancies. However, cytological preparation might be more sensitive for pancreatic lesions <3 cm.

Abstract
BACKGROUND AND AIM Recently, a 22-gauge (G) needle with a Franseen tip design was developed for endoscopic ultrasonography-guided fine-needle biopsy (EUS-FNB). The present study evaluated the performance of the Franseen biopsy needle in EUS-guided tissue acquisition. METHODS This is a retrospective study of patients who underwent EUS-FNB using the Franseen needle. Lesions were sampled using either the Franseen needle only or after failed diagnostic fine-needle aspiration (FNA). After rapid onsite evaluation (ROSE), two dedicated passes were carried out for histological assessment using the cell block technique. Main outcomes were: (i) rates of diagnostic adequacy for ROSE and histological diagnosis; and (ii) quality of histology as determined by total tissue area and tumor percentage in tissue. RESULTS Thirty patients underwent EUS-FNB of pancreatic or other masses over a 3-month period. Twenty-four lesions were sampled using the Franseen needle only and six after failed diagnostic FNA. Final diagnosis was pancreatic cancer in 12, gastrointestinal stromal cell tumor in five, other tumors in four and benign disease in nine. Diagnostic adequacy for ROSE was 96.6% and histological diagnosis was established in 96.7% of patients. Median tissue area was 2.9 mm2 (IQR = 0.68-8.71 mm2 ) and median tumor percentage in tissue was 73.9% (IQR = 44-97.6). Rates of technical success and adverse events were 96.7 and 3.3%, respectively. CONCLUSION Preliminary data suggest that the Franseen needle yields diagnostic material for ROSE and histology in >95% of patients.

Abstract
BACKGROUND AND OBJECTIVES A Canadian Community Hospital launched a new Endoscopic Ultrasound (EUS) Program in 2011. The aim of this study was to report the accuracy of EUS-fine needle aspiration (EUS-FNA) of solid lesions over time as it pertains to cytotechnologists' involvement and learning curves. METHODS The electronic medical records of patients that had a EUS from July 2011 to January 2014 were retrospectively reviewed. Only solid lesions with FNA sampling were included in the study. The primary outcome assessed was the accuracy of specimen acquisition for pathological review. The secondary outcome was diagnostic accuracy. Cases were separated by chronological order into thirds for the assessment of learning curves. Cytotechnologists' involvement was correlated to determine its impact on accuracy. RESULTS Two hundred and seventy-one EUS-FNA procedures were completed for solid lesions. Cytotechnologists' involvement resulted in a specimen acquisition accuracy of 82.6%, compared with 68.8% without a cytotechnologist (P = 0.009; 95% confidence interval [CI] 3.2%-25.0%). Diagnostic accuracy was 74.2% with a cytotechnologist while 62.4% without a cytotechnologist (P = 0.038; 95% CI 0.3%-23.7%). The specimen acquisition accuracy increased from 73.2% from the first third of cases to 92.3% for the last third with a cytotechnologist (P = 0.004; 95% CI 6%-33.0%). Without a cytotechnologist, the specimen accuracy was 67.6% for the first third while 57.7% for the last third of cases (P = 0.434; 95% CI - 33.9-14.4%). In the multivariable regression analysis, after adjusting for other predictors, a present cytotechnologist (P = 0.022) and lesion size 21 mm-30 mm (P = 0.039) and >30 mm (P = 0.001) were significantly associated with increased specimen acquisition accuracy. Only a present cytotechnologist (P = 0.046) was significantly associated with increased diagnostic accuracy. INTERPRETATION Cytotechnologists' involvement significantly improved the accuracy of specimen acquisition. Although accuracy was impacted by a cytotechnologist learning curve, our results highlight the importance of a cytotechnologist being present for EUS-FNA sampling of solid lesions.

KRAS mutation testing on all non-malignant diagnosis of pancreatic endoscopic ultrasound-guided fine-needle aspiration biopsies improves diagnostic accuracy. Pathology 2017; 49:379-386.

Abstract
Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is the procedure of choice for the cytologic diagnosis of pancreatic masses. The specificity of EUS-FNA approaches 100%, but the sensitivity is still low, and the high rate of indeterminate (atypical and suspicious) and false-negative results needs improvement. KRAS gene is frequently mutated in pancreatic ductal adenocarcinoma (PDAC) (up to 90%), and mutation analysis of KRAS has been proposed as diagnostic biomarker of PDAC. In most laboratories, KRAS mutation testing is performed by Sanger sequencing or real time-quantitative polymerase chain reaction (RT-qPCR), but these methods may give false-negative results in routine samples, mainly due to low cellularity. In order to increase the sensitivity of EUS-FNA, we propose a sequential approach for detecting KRAS mutations using mutant enriched-PCR (ME-PCR, sensitivity up to 0.1%) in cytologically indeterminate and negative samples tested wild-type by RT-qPCR. EUS-FNA specimens from 107 patients with pancreatic masses (51 males, 56 females, mean age 67 years) were cytologically examined. According to the Papanicolaou Society of Cytopathology guidelines, 50 cases (47%) were classified malignant, 15 (14%) suspicious, 13 (12%) atypical and 10 (9%) negative for malignancy; 18 cases (17%) were non-diagnostic. The overall specificity and sensitivity of cytological examination were 100% and 61%, respectively, when only negative and positive cases were considered; when atypical and suspicious were added to positive cases, the sensitivity increased to 95.1% and the specificity decreased to 85.7%. In all the cases, DNA was extracted from the cell-block and KRAS mutations were investigated by RT-qPCR, followed by ME-PCR in non-amplifiable and negative cases. The overall sensitivity and specificity of KRAS mutation testing alone were 79.3% and 100%; when KRAS mutation testing was performed in indeterminate and negative cytology, the sensitivity increased to 90% with specificity to 100%. Our data indicate that conventional cytology from EUS-FNA samples is highly specific for the diagnosis of pancreatic cancer. Indeterminate and negative cases need to be screened for KRAS mutations; this two-step approach may greatly improve the diagnostic accuracy of this method.

Abstract
Background Endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) has become the preferred method to diagnose pancreatic masses due to its minimally invasive approach and diagnostic accuracy. Many studies have shown that rapid on-site evaluation (ROSE) improves diagnostic yield by 10–30%; however, more recent studies have demonstrated effective diagnostic accuracy rates without ROSE. Our study aims to examine whether the current standard of performing ROSE after each FNA pass adds diagnostic value during EUS-guided FNA of pancreatic masses. Methods We conducted a retrospective case series on patients who underwent EUS-guided FNA of pancreatic masses between February 2011 and October 2014. All cases were performed by one of three endoscopists at Emory University Hospital. Patient demographics, radiologic details of pancreatic masses and pathology reports of the biopsied pancreatic masses were examined. Results A total of 184 procedures performed in 171 patients were reviewed. The final pathology reports of the biopsied pancreatic masses showed 128 (70%) with confirmed malignancy. Only 64 (50%) of these 128 cases initially showed malignant cells during ROSE. Among these 64 cases, 23% required 5 or more FNA passes to first detect malignant cells. Conclusions The use of ROSE during EUS-guided FNA of pancreatic masses may increase the diagnostic yield, since malignant cells were often detected during later FNA passes that would otherwise be missed if tissue sampling stopped prematurely. In addition, sample preparation for ROSE may be suboptimal, since malignant cells were only detected in 50% of cases.

Abstract
BACKGROUND Endoscopic ultrasound (EUS) is a well-established modality in diagnosing and staging of various neoplastic and non-neoplastic lesions. Its accuracy further increases in the presence of an on-site cytopathologist. There is a paucity of data on diagnostic yield of EUS-guided fine needle aspiration cytology (FNAC) without an on-site cytopathologist. METHODS Retrospective data were analyzed at SMS Medical College, Jaipur, from January 2014 to October 2015. All patients who underwent EUS-guided FNAC in the Department of Gastroenterology were included. Data related to demography, lesion parameters on EUS, and histology were analyzed. RESULTS Two hundred patients (age 46.2±18.6, 144 male) were studied. EUS-FNAC slides from 162 (82%) were considered adequate by cytopathologist for the diagnosis of benign or malignant lesions. Slide preparation adequacy was 100% for mediastinal and renal and suprarenal masses, 87.06% for pancreatic, 73.46% for lymph nodes, and 88.88% for other lesions. Mean number of passes was 1.92±0.82. CONCLUSIONS Diagnostic yield of EUS-guided FNAC is high even in the absence of on-site cytopathologist.

Abstract
Early diagnosis and accurate staging of pancreatic cancer is very important to plan optimal management strategy. Endoscopy plays an important role in the diagnosis and management of pancreatic cancer. Endoscopic ultrasound imaging (EUS) is the most sensitive modality for diagnosis, especially for small pancreatic tumors; it also allows tissue acquisition for histological diagnosis. Computed tomography scanning and EUS play complementary roles in staging and are comparable in determining resectability. Endoscopic retrograde cholangiopancreatography allows tissue sampling but is limited to palliative biliary drainage in most cases. In this article, we review the role of endoscopy in the diagnosis and management of pancreatic adenocarcinoma, with special emphasis on the use of endoscopic ultrasound and endoscopic retrograde cholangiopancreatography (ERCP).

Abstract
The negative predictive value of endoscopic ultrasonography fine-needle aspiration is relatively low. To achieve the improvement of the diagnostic yield, the following were proposed: a higher number of passes, the presence of the rapid on-site cytopathologist evaluation, the fanning technique, or the repetition of the fine needle biopsy. Harmonic contrast-enhanced endosonography may better identify the targeted area in the lesions by avoiding the inside necrosis and the vessels of fibrosis, so it can guide the fine-needle aspiration. Both techniques are complementary, not competitive, and they can be done in the same session. The combined technique is simple, safe, and requires only a few minutes with minimal extra costs compared to standard fine-needle aspiration. It minimally increases the diagnostic rate, and it permits the decrease of the number of passes. However, we will know its real clinical impact only in the future and whether it will be incorporated into the lesion assessment process.

Abstract
Background and Objectives: Previous limited experiences have reported the 19-gauge flexible needle to be highly effective in performing endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) for transduodenal lesions. We designed a large multicenter prospective study with the aim at evaluating the performance of this newly developed needle. Patients and Methods: Consecutive patients with solid lesions who needed to undergo EUS sampling from the duodenum were enrolled in 6 tertiary care referral centers. Puncture of the lesion was performed with the 19-gauge flexible needle (Expect™ and Slimline Expect™ 19 Flex). The feasibility, procurement yield, and diagnostic accuracy were evaluated. Results: Totally, 246 patients (144 males, mean age 65.1 ± 12.7 years) with solid lesions (203 cases) or enlarged lymph nodes (43 cases) were enrolled, with a mean size of 32.6 ± 12.2 mm. The procedure was technically feasible in 228 patients, with an overall procurement yield of 76.8%. Two centers had suboptimal procurement yields (66.7% and 64.2%). Major complications occurred in six cases: two of bleeding, two of mild acute pancreatitis, one perforation requiring surgery, and one duodenal hematoma. Considering malignant versus nonmalignant disease, the sensitivity, specificity, positive/negative likelihood ratios, and diagnostic accuracy were 70.7% (95% confidence interval [CI]: 64.3–76.6), 100% (95% CI: 79.6–100), 35.3 (95% CI: 2.3–549.8)/0.3 (95% CI: 0.2–0.4), and 73.6% (95% CI: 67.6–79). On multivariate analysis, the only determinant of successful EUS-FNB was the center in which the procedure was performed. Conclusions: Our results suggest that the use of the 19-gauge flexible needle cannot be widely advocated and its implementation should receive local validation after careful evaluation of both the technical success rates and diagnostic yield.

Abstract
Accurate diagnosis and staging of pancreatic neoplasms is essential for surgical planning and identification of locally advanced and metastatic disease that is incurable by surgery. The ability to position the endoscopic ultrasonography (EUS) transducer close to the pancreas combined with the use of fine-needle aspiration enables the accurate diagnosis of pancreatic cysts and solid masses. EUS is also increasingly being used to procure core tissue for molecular analysis that facilitates personalized treatment of pancreatic cancer. Various therapeutic interventions can be undertaken under EUS guidance. This article focuses on the applications of EUS and endoscopic retrograde cholangiopancreatography in pancreatic neoplasms.

Abstract
Indeterminate cytologic diagnoses in endoscopic ultrasound guided fine needle aspiration biopsy (EUS-FNA) of solid pancreatic lesions include the diagnostic categories "atypical" (ATY) and "suspicious for malignancy" (SUSP), which are used at variable rates and are associated with variable underlying risk of malignancy. The aim of this study was to determine individual cytopathologists' rates of indeterminate diagnoses in EUS-FNA of solid pancreatic lesions and their relationship to cytopathologists' experience and volume of pancreatic EUS-FNA examined, as well as the potential impact of departmental consensus review on indeterminate diagnoses. DESIGN The diagnostic rates of ATY and SUSP and their underlying risk of malignancy were calculated for six cytopathologists who diagnosed 1,114 of 1,225 EUS-FNA of solid pancreatic lesions from 1/1/2001 to 9/15/2014, and were then compared for the periods before and after the implementation of departmental consensus review during 2009. RESULTS The six cytopathologists diagnosed 10% of cases as indeterminate; 82 (7.4%) as "atypical" and 29 (2.6%) as "suspicious". The individual cytopathologists' indeterminate diagnosis rates varied twofold (6.67-12.80%) and did not correlate with their experience, total or annual volume of EUS-FNAs. Of the 56/99 (56.57%) cases with follow-up, the underlying rate of malignancy was 47% (35/75; for "atypical" and 87.5% (21/24); for "suspicious"). The underlying rates of malignancy were 33-67% for "atypical" and 80-100% for "suspicious" diagnoses made by individual cytopathologists. The rate of indeterminate diagnoses decreased from 11.55 to 7.88% after the implementation of departmental consensus review. CONCLUSION Individual cytopathologists' rates of indeterminate diagnoses and their significance vary; however, consensus review is helpful in reducing these rates. Diagn.

Abstract
The diagnostic approach to a possible pancreatic mass lesion relies first upon various non-invasive imaging modalities, including computed tomography, ultrasound, and magnetic resonance imaging techniques. Once a suspect lesion has been identified, tissue acquisition for characterization of the lesion is often paramount in developing an individualized therapeutic approach. Given the high prevalence and mortality associated with pancreatic cancer, an ideal approach to diagnosing pancreatic mass lesions would be safe, highly sensitive, and reproducible across various practice settings. Tools, in addition to radiologic imaging, currently employed in the initial evaluation of a patient with a pancreatic mass lesion include serum tumor markers, endoscopic retrograde cholangiopancreatography, and endoscopic ultrasound-guided fine needle aspiration (EUS-FNA). EUS-FNA has grown to become the gold standard in tissue diagnosis of pancreatic lesions.

Abstract
We report a case of a 64-year-old woman with anaplastic carcinoma of the pancreas (ACP) with cyst formation and review 60 ACP cases reported in Japan. In 20% of cases, laboratory tests revealed severe anemia (hemoglobin level < 10.0 g/dL) and elevated leucocyte counts (> 12000/mm3), which were likely attributable to rapid tumor growth, intratumoral hemorrhage, and necrosis. Elevated serum CA19-9 levels were observed in 55% of cases. Cyst-like structures were observed on imaging in 47% of cases, and this finding appears to reflect subsequent cystic degeneration in the lesion. Macroscopically, hemorrhagic necrosis was observed in 77% of cases, and cyst formation was observed in 33% of cases. ACP should be considered when diagnosing pancreatic tumors with a cyst-like appearance, especially in the presence of severe anemia, elevated leucocyte counts, or elevated serum CA19-9 levels.

Abstract
BACKGROUND AND AIMS Tissue diagnosis, regardless of technique or endoscope used, can be challenging in patients with indeterminate biliary strictures (IDBSs). This exploratory study evaluated the utility and role of rapid onsite evaluation of touch imprint cytology (ROSE-TIC) when single-operator cholangioscopy (SOC)-guided biopsies of IDBSs are performed. METHODS Patients with IDBSs were evaluated by intraprocedural ROSE-TIC during SOC-guided biopsy procedures. Final diagnosis was established by long-term patient follow-up in conjunction with off-site findings or surgical histology. The main outcome measure was to evaluate the utility of ROSE-TIC by determination of its operating characteristics and comparison with off-site histologic assessment. RESULTS Of 31 patients with IDBSs, tissue diagnosis was indeterminate at prior ERCP-guided brush and/or biopsy in 14, prior EUS-guided FNA (EUS-FNA) in 6, and a mass could not be identified at EUS in 11. The mean number of biopsies performed was 3.3 (range 1-8), and diagnostic interpretation by ROSE-TIC was diagnostic and/or suspicious for carcinoma in 15, benign in 13, atypical-reactive in 2, and bile duct intraductal papillary mucinous neoplasm in 1. Final diagnosis by surgical histology (n = 4), death by disease (n = 10), and patient follow-up (n = 17) showed that the overall sensitivity of ROSE-TIC for diagnosing malignancy was 100%, specificity 88.9%, positive predictive value 86.7%, negative predictive value 100%, and diagnostic accuracy 93.5%. CONCLUSIONS Preliminary data suggest that the diagnostic outcomes of SOC-guided biopsies in IDBSs can be significantly improved by using ROSE-TIC. This technique also may benefit centers that rely mainly on fluoroscopy-guided intraductal biopsies.

Rapid On-Site Evaluation Does Not Improve Endoscopic Ultrasound-Guided Fine Needle Aspiration Adequacy in Pancreatic Masses: A Meta-Analysis and Systematic Review. PLoS One 2016; 11:e0163056.

Abstract
Background and Objectives Rapid on-site evaluation (ROSE) during endoscopic ultrasonography-guided fine needle aspiration (EUS–FNA) of pancreatic masses has been reported to be associated with improved adequacy and diagnostic yield. However, recent observational data on the impact of ROSE have reported conflicting results. A meta-analysis and systematic review was therefore conducted to evaluate the contribution of ROSE during EUS-FNA of pancreatic masses. Method A systematic search was conducted in MEDLINE/Pubmed and EMBASE databases for studies comparing the efficacy of ROSE between patients in two cohorts. Outcomes considered included diagnostic adequate rate, diagnostic yield, number of needle passes, pooled sensitivity and specificity. Findings from a random-effects model were expressed as pooled risk difference (RD) with 95% confidence intervals (CIs). Results A total of 7 studies (1299 patients) was finally included and further analyzed in the current meta-analysis. EUS-FNA with ROSE could not improve diagnostic adequacy (RD = 0.05, 95% CI: -0.01–0.11) and diagnostic yield (RD = 0.04 95%CI: -0.05, 0.13). The number of needle passes showed no statistically significant difference with and without ROSE (RD = -0.68 95%CI: -2.35, 0.98). The pooled sensitivity and specificity of ROSE group were 0.91 (95%CI: 0.87, 0.94) and 1 (95%CI: 0.94, 1.00). The pooled sensitivity and specificity of non-ROSE group were 0.85 (95%CI: 0.80, 0.89) and 1 (95%CI: 0.95, 1.00). ROSE group and non-ROSE group showed comparable sensitivity and specificity. Conclusion Compared to historical reports of its clinical efficacy in patients with pancreatic lesions, ROSE may be not associated with an improvement of diagnostic yield, adequate rate, pooled sensitivity and specificity.

Abstract
Pancreatic cancer is the fifth leading cause of cancer death and has the lowest survival rate of any solid cancer. Endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNA) is currently capable of providing a cytopathological diagnosis of pancreatic malignancies with a higher diagnostic power, with a sensitivity and specificity of 85%-89% and 98%-99%, compared to pancreatic juice cytology (PJC), whose sensitivity and specificity are only 33.3%-93% and 83.3%-100%. However, EUS-FNA is not effective in the cases of carcinoma in situ and minimally invasive carcinoma because both are undetectable by endoscopic ultrasonography, although PJC is able to detect them. As for the frequency of complications such as post endoscopic retrograde cholangiopancreatography pancreatitis, EUS-FNA is safer than PJC. To diagnose pancreatic cancer appropriately, it is necessary for us to master both procedures so that we can select the best methods of sampling tissues while considering the patient’s safety and condition.

Abstract
BACKGROUND Endoscopic ultrasound guided elastography is an imaging modality that can be used to evaluate tissue stiffness and to assess solid pancreatic lesions. It can also assist in optimizing the diagnostic yield of endoscopic ultrasound guided fine needle aspiration biopsies. AIMS To review the literature on solid pancreatic lesions, the use of EUS guided fine needle aspiration and endoscopic ultrasound guided elastography and to present a single center experience using elastography to direct fine needle aspiration biopsies of solid pancreatic lesions. METHODS We present a review of the literature and a single center experience describing the use of EUS guided elastography in directing fine needle aspiration biopsies of solid pancreatic lesions. RESULTS Thirteen male veterans with an average age of 62.3 (SD±11.8) years were enrolled in the study. The mean pancreatic mass size on EUS was 5.1×5.2 (SD±4.4×4.5) cm. A total of 13 lesions were identified during elastography. The lesions were most commonly found in the body (n=5), followed by multifocal lesions (n=4), pancreatic head (n=3) and tail (n=1). The seven concerning pancreatic lesions were stratified based on color pattern identified on EUS and EUS-elastography. Three lesions were homogenously blue, and four lesions were heterogeneously blue. The remaining six lesions which were less concerning were predominantly green. Of the three lesions, that were homogenously blue, two were diagnosed as adenocarcinoma (n=2) and chronic pancreatitis (n=1) respectively. Of the four heterogeneously blue lesions two were adenocarcinomas, while the other two represented a large B-cell lymphoma and chronic pancreatitis. Patients whose lesions were characterized as homogenous or heterogeneous green were benign and remained disease free after a median of two years of regular follow up. LIMITATIONS Relatively small number of patients studied. CONCLUSIONS In our single center experience we found that the use of real time endoscopic ultrasound guided elastography for targeting fine needle aspiration of suspicious pancreatic lesions may be beneficial as an adjunct modality to complement conventional EUS. Larger prospective studies need to be conducted to evaluate the utility of this modality in targeting pancreatic lesions.

Abstract
Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is widely used to obtain a definitive diagnosis of pancreatic tumors. Good results have been reported for its diagnostic accuracy, with high sensitivity and specificity of around 90%; however, technological developments and adaptations to improve it still further are currently underway. The endosonographic technique can be improved when several tips and tricks useful to overcome challenges of EUS-FNA are known. This review provides various techniques and equipment for improvement in the diagnostic accuracy in EUS-FNA.

Abstract
BACKGROUND AND AIMS There are currently no prospective, controlled trials of needle puncture speed in EUS-guided FNA (EUS-FNA). In this study, we prospectively evaluated the accuracy of histological diagnosis and the tissue acquisition rate of EUS-FNA by using the door-knocking method (DKM) with a standard 22-gauge needle. METHODS From November 2013 to August 2014, 82 patients who had solid pancreatic masses underwent EUS-FNA in which the conventional method (CM) and DKM with 2 respective passes in turn were used. The primary outcomes of this study were the accuracy of histological diagnosis and the rates of tissue acquisition in 2 FNA procedures by using these 2 methods. RESULTS Although the successful tissue acquisition rate for histology was not significantly different with the DKM and CM (91.5% vs 89.0%, P = .37), the high cellularity tissue acquisition rate for histology with the DKM was significantly superior to that with the CM (54.9% vs 41.5%, P = .03). However, adequate quality rate and accuracy were not different in the DKM and CM (78.0% vs 80.5%, P = .42 and 76.8% vs 78.0%, P = .50, respectively). In the transgastric puncture group, although the adequate quality rate and accuracy were similar in the DKM and CM (84.1% vs 79.4%, P = .30 and 84.1% vs 76.2%, P = .11, respectively), the tissue acquisition rate tended to be higher with the DKM than the CM (93.7% vs 85.7%, P = .06). Moreover, the high cellularity tissue acquisition rate was significantly better with the DKM than the CM (63.5% vs 39.7%, P = .002). On the other hand, in the transduodenal puncture group, although the tissue acquisition rate was similar with the DKM and CM (84.2% vs 100%, P = .13), the adequate quality rate and accuracy were significantly lower with the DKM than with the CM (57.9% vs 84.2%, P = .03 and 52.6% vs 84.2%, P = .02, respectively). CONCLUSION EUS-FNA by using a 22-gauge needle with the DKM did not improve the accuracy of histological diagnosis, but enabled acquisition of a larger amount of tissue specimen by using transgastric puncture.

Abstract
BACKGROUND Rapid on-site evaluation (ROSE) improves the adequacy and accuracy of EUS-guided tissue acquisition, although it is not routinely widely available. Evidence suggested that core needles might overcome the absence of ROSE. The aim of this study was to evaluate the influence of ROSE on the adequacy and accuracy of EUS-guided tissue acquisition with core needles in patients with pancreatic solid lesions. METHODS Patients who underwent EUS-guided tissue acquisition of pancreatic mass lesions were retrospectively identified at three tertiary referral centers and those performed with the core needle were included. Adequacy, defined as the rate of cases in which a tissue specimen for proper examination was achieved, with and without ROSE was the primary outcome measure. The diagnostic accuracy and tissue core acquisition were the secondary outcome measures. RESULTS A total of 333 patients with pancreatic solid mass lesions were included in the study; 140 cases sampled with ROSE and 193 cases without ROSE. The adequacy was 92.1 % in the group sampled with ROSE and 88.1 % in the group without ROSE (p = 0.227). In the ROSE group sensitivity, specificity, and accuracy were 90.7, 100 and 92.1 %, respectively. In the group without ROSE, sensitivity, specificity, and accuracy were 87.2, 100, and 88.1 %, respectively. No difference for all these figures was observed between the two groups. The tissue core was available in 61.4 and 53.4 % of cases with and without ROSE, respectively (p = 0.143). CONCLUSION In the absence of ROSE, EUS-based tissue acquisition with Core needle should be considered since it achieves comparable tissue sampling adequacy and accuracy.

Abstract
BACKGROUND AND STUDY AIMS Techniques to optimize endoscopic ultrasound-guided tissue acquisition (EUS-TA) in a variety of lesion types have not yet been established. The primary aim of this study was to compare the diagnostic yield (DY) of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) to endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) for pancreatic and non-pancreatic masses. PATIENTS AND METHODS Consecutive patients referred for EUS-TA underwent randomization to EUS-FNA or EUS-FNB at four tertiary-care medical centers. A maximum of three passes were allowed for the initial method of EUS-TA and patients were crossed over to the other arm based on on-site specimen adequacy. RESULTS A total of 140 patients were enrolled. The overall DY was significantly higher with specimens obtained by EUS-FNB compared to EUS-FNA (90.0 % vs. 67.1 %, P = 0.002). While there was no difference in the DY between the two groups for pancreatic masses (FNB: 91.7 % vs. FNA: 78.4 %, P = 0.19), the DY of EUS-FNB was higher than the EUS-FNA for non-pancreatic lesions (88.2 % vs. 54.5 %, P = 0.006). Specimen adequacy was higher for EUS-FNB compared to EUS-FNA for all lesions (P = 0.006). There was a significant rescue effect of crossover from failed FNA to FNB in 27 out of 28 cases (96.5 %, P = 0.0003). Decision analysis showed that the strategy of EUS-FNB was cost saving compared to EUS-FNA over a wide range of cost and outcome probabilities. CONCLUSIONS RESULTS of this RCT and decision analysis demonstrate superior DY and specimen adequacy for solid mass lesions sampled by EUS-FNB.

Abstract
BACKGROUND AND AIM To improve diagnostic yield of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in solid pancreatic lesions, on-site cytology review has been recommended. Because this is not widely available throughout the world, the aim of this study was to compare the diagnostic yield of EUS-FNA performed with rapid on-site evaluation (ROSE) versus 7 FNA passes without ROSE in pancreatic masses. METHODS In this multicenter randomized noninferiority trial, patients were randomized to ROSE versus 7 passes into a solid pancreatic mass. On the basis of the absolute difference in diagnostic yield with 7 passes versus cytopathologist-guidance, the noninferiority margin for the difference in diagnostic yield was defined as -15%. Definite diagnosis was defined to include positive for malignancy, neoplastic cells present, and negative for malignancy. RESULTS A total of 142 patients were randomized with 73 in the cytopathologist arm and 69 in the 7 passes arm. Diagnostic yield for definite diagnosis was 78.3% with 7 passes and 78.1% with cytopathology guidance. With an absolute difference 0.2%, 95% CI -14.4 to 14.6, performing 7 passes was noninferior to cytopathologist-guided EUS-FNA. There was no significant difference in complications or time to perform FNA. A median of 5 passes were performed with ROSE. The median charge with onsite cytopathology was significantly greater than performing 7 passes [$1058 (958, 1445) versus $375 (275, 460), p<0.001]. CONCLUSIONS The diagnostic yield for performing 7 passes during EUS-FNA into solid pancreatic masses is noninferior with lower charge compared to cytopathologist-guidance.

Abstract
Aim: To reveal the impact of preoperative endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) of pancreatic ductal adenocarcinoma (PDAC). Materials and Methods: We retrospectively reviewed 242 patients who underwent surgery for PDAC at our institution between January 1996 and July 2012. Among them, there were three patients with R2 resection and 30 patients with a follow-up period of less than 1 year, who were excluded because they did not meet the conditions for evaluating recurrence. Consequently, 209 patients were enrolled in the present study. The patients were divided into two groups: 126 patients who underwent preoperative EUS-FNA (FNA group) and 83 patients who did not (non-FNA group) undergo preoperative EUS-FNA. Results: There were no significant differences in baseline characteristics between FNA and non-FNA groups except mean age (66.6 ± 8.9 years vs. 63.5 ± 8.9 years, respectively, P = 0.02) and the administration rate of gemcitabine as adjuvant chemotherapy (42.9% vs. 18.1%, P < 0.01). Sampling adequacy of preoperative EUS-FNA was 99.2% (125/126) and sensitivity for diagnosis was 92.9% (117/126). The rate of complications related to EUS-FNA was 1.6% (2/126); two patients experienced reduction in hemoglobin (≥2.0 g/dL). These two patients did not have any apparent bleeding and could be managed conservatively. No severe complications were seen. We evaluated long-term outcomes of preoperative EUS-FNA, especially disease-free survival, needle-track seeding and recurrence. Kaplan-Meier analysis indicated no significant difference in disease-free survival between the two groups (P = 0.12). The site of recurrence was not significantly different between groups. Needle-track seeding was not observed in this study. Multivariate analysis of recurrence factors showed that preoperative EUS-FNA did not affect postoperative recurrence. Conclusion: Preoperative EUS-FNA for PDAC was shown to be a safe procedure with high diagnostic ability, and not a risk factor for postoperative recurrence.

Abstract
OBJECTIVE To determine the feasibility of genotyping pancreatic tumors via fine needle aspirates (FNAs). BACKGROUND FNA is a common method of diagnosis for pancreatic cancer, yet it has traditionally been considered inadequate for molecular studies due to the limited quantity of DNA derived from FNA specimens and tumor heterogeneity. METHODS In vitro mixing studies were performed to deduce the minimum cellularity needed for genetic analysis. DNA from both simulated FNAs and clinical FNAs was sequenced. Mutational concordance was determined between simulated FNAs and that of the resected specimen. RESULTS Limiting dilution studies indicated that mutations present at allele frequencies as low as 0.12% are detectable. Comparison of simulated FNAs and matched tumor tissue exhibited a concordance frequency of 100% for all driver genes present. In FNAs obtained from 17 patients with unresectable disease, we identified at least 1 driver gene mutation in all patients including actionable somatic mutations in ATM and MTOR. The constellation of mutations identified in these patients was different than that reported for resectable pancreatic cancers, implying a biologic basis for presentation with locally advanced pancreatic cancer. CONCLUSIONS FNA sequencing is feasible and subsets of patients may harbor actionable mutations that could potentially impact therapy. Moreover, preoperative FNA sequencing has the potential to influence the timing of surgery relative to systemic therapy. FNA sequencing opens the door to clinical trials in which patients undergo neoadjuvant or a surgery-first approach based on their tumor genetics with the goal of utilizing cancer genomics in the clinical management of pancreatic cancer.

Abstract
BACKGROUND AND STUDY AIMS Despite a well-established tool for diagnosis of pancreatic masses, endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) studies have shown suboptimal diagnostic performance at divergent mass sizes. Since the impact of gold standard follow-up and presence of on-site evaluation on this observation is unknown, we aimed to study the performance characteristics of EUS-FNA under these strict conditions. PATIENTS AND METHODS EUS-FNA results from pancreatic mass lesions performed between July 2000 and March 2013 were evaluated. All patients with histological follow-up were then stratified into four groups: Group A ( ≤ 10 mm), Group B (11 - 20 mm), Group C (21 - 40 mm), and Group D (> 40 mm). Sensitivity and diagnostic accuracy were calculated for each group and compared. RESULTS A total of 612 /3832 (16 %) patients with pancreatic masses who underwent EUS-FNA had histology confirmation. Of these, 81 were excluded due to unavailable lesion size, while the rest formed the study cohort. Mean age (SD) was 65.8 years (9.3) with 51.2 % female. The mean number of passes for the entire cohort was 2.9 (SD 1.9; range 1 - 12); patients in group D had a significantly higher number of passes for on-site diagnosis (P = 0.0124). There was no significant difference between the groups for sensitivity (P = 0.1134) or diagnostic accuracy (P = 0.2111). Proportional trend analysis revealed no significant correlation between size and sensitivity (P = 0.6192). The size of lesion measured by EUS was not associated with sensitivity or specificity after adjusting for age, sex, and pancreatic location. CONCLUSION In the presence of rapid on-site cytopathology and when final histology is taken as the gold standard, pancreatic mass size does not affect the performance characteristics of EUS-FNA.

Abstract
Endoscopic ultrasound (EUS)-guided tissue acquisition has emerged over the last decade as an invaluable diagnostic tool in approaching the different pancreatic lesions. Given the safety and minimal invasiveness of this approach combined with the high diagnostic yield, it became the standard of care when dealing with different pancreatic pathologies. However, some variables regarding this procedure remain not fully understood. These can influence the diagnostic yield of the procedure and include the presence of the on-site cytopathologist, the type and size of the needle used as well as obtaining aspiration versus core biopsy, the number of passes and the sampling technique, and the role of suction and stylet use among others. We performed a comprehensive literature search using PubMed, Google Scholar, and Embase for studies that assessed these variables. Eligible studies were analyzed using several parameters such as technique and procedure, with the aim of reviewing results from an evidence-based standpoint.

Abstract
OBJECTIVES To identify factors differentiating pancreatic neuroendocrine tumors (PNETs) from non-PNET neoplastic solid pancreatic lesions (SPLs) and assess the accuracy of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). METHODS This is a retrospective study at a tertiary center of consecutive patients referred for EUS from 2004 to 2011. The main outcomes were pretest predictors and accuracy of EUS-FNA for diagnosis of PNET. RESULTS Among a total of 1108 EUS-FNAs for pancreatic lesions, 672 patients (PNET = 91, non-PNET neoplastic-SPLs = 581) had neoplastic-SPLs. The sensitivity, specificity, and accuracy of EUS-FNA for diagnosis of PNETs were 98.9%, 100%, and 99.9%, respectively. The mean needle-passes were 3.0/patient. The EUS volume (mean/year per endosonographer) in preceding 3 years significantly correlated with fewer needle passes (rs: [-0.26]; P = 0.02).Multivariate analysis demonstrated that patients with PNET when compared to non-PNET neoplastic-SPLs were younger (odds ratio [OR], 3.23; 95% confidence interval [95% CI], 1.19-9.09; P = 0.001), have 2 or more pancreatic lesions (OR, 5.63; 95% CI, 1.74-18.2; P = 0.005), and lower CA 19-9 values (OR, 10.0; 95% CI, 3.13-33.3; P = 0.001). Further, PNETs were less likely to have weight loss (OR, 0.40; 95% CI, 0.17-0.90; P = 0.03), current smoking (OR, 0.47; 95% CI, 0.22-0.98; P < 0.05), pancreatic ductal dilation (OR, 0.28; 95% CI, 0.13-0.60; P = 0.002), or imaging evidence of arterial invasion (OR, 0.22; 95% CI, 0.07-0.71; P = 0.01). CONCLUSIONS Although pre-FNA findings can reliably characterize, EUS-FNA is highly accurate for the diagnosis of PNETs.

Abstract
We reported three cases of mass-forming type 1 autoimmune pancreatitis (AIP) that were preoperatively suspected to be pancreatic cancer, and reviewed their clinicopathological features. Radiological findings in the patients revealed hypoattenuating masses in the early phase or a stricture of the main pancreatic duct with upstream dilatation, which was consistent with the diagnosis of pancreatic cancer. Histopathologically, the lesions were well demarcated and met all diagnostic criteria for immunoglobulin G4 (IgG4)-related AIP, including the presence of periductal lymphoplasmacytic infiltration, obliterative phlebitis, storiform fibrosis and abundant IgG4-positive plasma cells. However, the adjacent uninvolved pancreatic duct and lobular structures were well preserved. And in all patients, none or some of the aforementioned characteristics were observed. We suggest that some cases of focal AIP may progress to more severe grades and exhibit mass formation, although remaining localized. These focal cases of AIP are difficult to distinguish from pancreatic cancer. To our knowledge, this report is the first to present a histopathological comparison of mass-forming AIP with the adjacent uninvolved pancreatic tissues.

Abstract
For the first several years after its development, endoscopic ultrasound (EUS) was primarily limited to identification of pancreatic malignancies. Since this time, the field of EUS has advanced at a tremendous speed in terms of additional clinical diagnostic and therapeutic uses. The combination of ultrasound with endoscopy provides a unique interventional modality that is a minimally invasive alternative to various surgical interventions. Given the expanding recommended indications for EUS, this article will serve to review the most common uses with supporting evidence, while also exploring innovative endeavors that may soon become common clinical practice.

Abstract
BACKGROUND Pancreatic masses may seldom represent a metastasis or secondary involvement by lymphoproliferative disorders. Recognition of this uncommon occurrence may help render an accurate diagnosis and avoid diagnostic pitfalls during endoscopic ultrasound-guided fine needle aspiration (EUS-FNA). In this study, we review our experience in diagnosing secondary tumors involving the pancreas. MATERIALS AND METHODS The electronic database of cytopathology archives was searched for cases of secondary tumors involving the pancreas at our institution and a total of 31 cases were identified. The corresponding clinical presentations, imaging study findings, cytological diagnoses, the results of ancillary studies, and surgical follow-up, if available, were reviewed. RESULTS Nineteen of the patients were male and 12 female, with a mean age of 66 years. Twenty-three patients (74%) had a prior history of malignancy, with the latency ranging from 6 months to 19 years. The secondary tumors involving the pancreas included metastatic carcinoma (24 cases), metastatic sarcoma (3 cases), diffuse large B-cell lymphoma (2 cases), and plasma cell neoplasm (2 cases). The most common metastatic tumors were renal cell carcinoma (8 cases) and lung carcinoma (7 cases). Correct diagnoses were rendered in 29 cases (94%). The remaining two cases were misclassified as primary pancreatic carcinoma. In both cases, the patients had no known history of malignancy, and no ancillary studies were performed. CONCLUSIONS Secondary tumors involving the pancreas can be accurately diagnosed by EUS-FNA. Recognizing uncommon cytomorphologic features, knowing prior history of malignancy, and performing ancillary studies are the keys to improve diagnostic performance and avoid diagnostic pitfalls.

Abstract
Endoscopic ultrasound (EUS) has become an important component in the diagnosis and treatment of carcinoma pancreas. With the advent of advanced imaging techniques and tissue acquisition methods the role of EUS is becoming increasingly important. Small pancreatic tumors can be reliably diagnosed with EUS. EUS guided fine needle aspiration establishes diagnosis in some cases. EUS plays an important role in staging of carcinoma pancreas and in some important therapeutic methods that include celiac plexus neurolysis, EUS guided biliary drainage and drug delivery. In this review we attempt to review the role of EUS in diagnosis and management of carcinoma pancreas.

Abstract
BACKGROUND AND STUDY AIMS Endoscopic ultrasound-guided needle-based confocal laser endomicroscopy (EUS-nCLE) has been shown to aid in the diagnosis of cystic pancreatic lesions. This is a pilot project to study its findings in patients with solid pancreatic lesions (SPLs) with a prospective single-blinded study design. METHODS Patients with SPLs undergoing trans-gastric EUS fine needle aspiration (EUS-FNA) from July 2013 to March 2014 were prospectively enrolled. The nCLE diagnoses were compared with the final diagnoses. Researchers learned about the EUS-nCLE findings from previously published studies and applied it to diagnose SPLs. In the meantime, the findings were recorded. RESULTS In total, 22 patients were recruited (mean age 62.7 years, SD 13.8 years; 14 men and eight women). The mean maximal tumor diameter was 36.0 mm (SD 10.9 mm). EUS-nCLE yielded satisfactory images in all patients during the first EUS procedure and diagnosed benign and malignant SPLs in 3 and 19 patients, respectively. Final diagnoses of malignant SPLs were made in 19 patients. Benign SPLs were eventually diagnosed in three patients, with confirmed the cytology and disease stability during the 12-month follow-up period. At the end of the project, based on the results of this current study, EUS-nCLE findings for malignant SPLs were dark clumping with or without dilated vessels (> 40 μm). There were two criteria for diagnosing benign lesions which were white fibrous bands and normal acini cells. The accuracy rate of EUS-nCLE was 90.9 % (20/22). One falsely diagnosed malignant SPL was an inflammatory mass from a recent acute pancreatitis. Another one with a pancreatic neuroendocrine tumor presenting with a symptomatic pseudocyst was incorrectly diagnosed as an inflammatory mass. This was likely from sampling error of the EUS-nCLE probe in an inflammatory area. Only one patient had post EUS-FNA bleeding but did not require a blood transfusion. The inter-observer agreement among three blinded endoscopists was almost perfect (Kappa 0.82). CONCLUSION EUS-nCLE is a promising technique for the diagnosis of SPLs with good inter-observer agreement. Study registration: TCTR20140402001.

Abstract
BACKGROUND Scanty data on the performance of the new 25-gauge Procore™ biopsy needle are available. METHODS Consecutive patients who underwent endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) using the 25G Procore™ were retrospectively retrieved. All samples were independently reviewed by 3 pathologists for the following: histological, cytological or no specimen, neoplasia, diagnostic or non-diagnostic. Diagnostic accuracy and inter-rater concordance among pathologists were calculated. RESULTS 94 patients underwent EUS-FNB of 101 sites (69 solid masses, 25 lymph nodes, 5 wall thickening). Forty-one biopsies (40.5%) were classified as histological samples by at least two pathologists, 29 as cytological (28.7%), 31 had no sample (30.7%). Good and almost perfect agreements among pathologists in defining cytological vs. histological samples (k 0.82; 95% CI: 0.74-0.90), diagnostic vs. non-diagnostic (k 0.95; 95% CI: 0.85-1.00) and neoplastic vs. non-neoplastic (k 0.94; 95% CI: 0.83-1.00). According to consensus rating, 61 cases were diagnostic samples (60.4%). Histological samples were more likely to lead to a correct diagnosis (OR, 4.1; 95% P=0.027), while neoplastic lesions were less likely to be correctly classified than benign (OR, 0.11; P=0.04). CONCLUSIONS EUS-FNB with the Procore™ 25G needle provided samples for histological examination in only 40% of the cases, with 31% of inadequate specimens, despite excellent results in term of inter-observer variability.

Abstract
OBJECTIVES Observational data on the impact of on-site cytopathology evaluation (OCE) during endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA) of pancreatic masses have reported conflicting results. We aimed to compare the diagnostic yield of malignancy and proportion of inadequate specimens between patients undergoing EUS-FNA of pancreatic masses with and without OCE. METHODS In this multicenter randomized controlled trial, consecutive patients with solid pancreatic mass underwent randomization for EUS-FNA with or without OCE. The number of FNA passes in the OCE+ arm was dictated by the on-site cytopathologist, whereas seven passes were performed in OCE- arm. EUS-FNA protocol was standardized, and slides were reviewed by cytopathologists using standardized criteria for cytologic characteristics and diagnosis. RESULTS A total of 241 patients (121 OCE+, 120 OCE-) were included. There was no difference between the two groups in diagnostic yield of malignancy (OCE+ 75.2% vs. OCE- 71.6%, P=0.45) and proportion of inadequate specimens (9.8 vs. 13.3%, P=0.31). Procedures in OCE+ group required fewer EUS-FNA passes (median, OCE+ 4 vs. OCE- 7, P<0.0001). There was no significant difference between the two groups with regard to overall procedure time, adverse events, number of repeat procedures, costs (based on baseline cost-minimization analysis), and accuracy (using predefined criteria for final diagnosis of malignancy). There was no difference between the two groups with respect to cytologic characteristics of cellularity, bloodiness, number of cells/slide, and contamination. CONCLUSIONS Results of this study demonstrated no significant difference in the diagnostic yield of malignancy, proportion of inadequate specimens, and accuracy in patients with pancreatic mass undergoing EUS-FNA with or without OCE.

Abstract
BACKGROUND AND AIM Early diagnosis of solid pancreatic lesions (SPLs) enables prompt treatment. The study aims to identify factors differentiating metastatic lesion to the pancreas (PMET) from pancreatic ductal adenocarcinoma (PDAC) and pancreatic neuroendocrine tumors (PNETs). METHODS This is a retrospective study at a tertiary cancer center. Consecutive patients referred for endoscopic ultrasound (EUS) of SPLs from 2004 to 2011 were reviewed. The main outcomes were pre-EUS-FNA (endoscopic ultrasound-guided fine needle aspiration) predictors and diagnostic accuracy of EUS-FNA for PMETs. RESULTS Among a total of 1108 EUS-FNAs for pancreatic lesions, 672 patients had neoplastic SPLs (PMETs = 53; PDACs = 528, PNETs = 91). The sensitivity, specificity, positive predictive value, and accuracy of EUS-FNA for diagnosis of PMETs were 84.9%, 100%, 100%, and 98.8%, respectively. The mean number of EUS-FNA passes for diagnosis of PMET was 3.1 per patient. For each endosonographer, preceding 3-year EUS volume (mean/year) significantly correlated with fewer needle passes (rs [-0.30], P = 0.03). The most common PMET was renal cell carcinoma. Stratified multivariate analyses were performed. Compared with patients with PDACs, PMETs were more common in men (odds ratio [OR] = 2.0; 95% confidence interval [CI] = 1.0-4.0); located in the pancreatic tail (OR = 2.4; 95%CI = 1.1-5.2); and were less likely with increasing age (OR = 0.95; 95%CI = 0.92-0.99), presence of major symptoms (abdomen pain/diarrhea/weight loss; OR = 0.2; 95%CI = 0.1-0.4), elevated bilirubin (OR = 0.3; 95%CI = 0.13-0.69), and imaging evidence of arterial invasion (OR = 0.15; 95%CI = 0.03-0.67). Compared with PNETs, PMETs were more common with increase age (OR = 1.05; 95%CI = 1.02-1.08) and increasing lesion size (OR = 1.03; 95%CI = 1.0-1.1), and were less likely in patients with diabetes (OR = 0.34; 95%CI = 0.11-0.99). CONCLUSION Among the largest numbers of neoplastic SPLs evaluated at a single center, pre-test features reliably characterize, and EUS-FNA provides a highly specific diagnosis of PMETs.

Abstract
OBJECTIVES To evaluate the diagnostic accuracy and complication rate of percutaneous ultrasound-guided fine-needle aspiration (US-FNA) of solid pancreatic neoplasms through the analysis of 10-year experiences of two centres. METHODS Clinical, radiological and pathologic data of 2,024 patients with solid pancreatic masses who underwent US-FNAs were retrospectively evaluated. Indications for aspiration were: unresectable lesions before neo-adjuvant therapy; doubtful imaging findings; and suspicion of uncommon neoplasms with prognostic or therapeutic implications such as metastases or lymphoma. US-FNAs were performed using aspiration needles with a cytopathologist present in centre 1. In centre 2, cytologic samples were collected with Chiba needles and separately evaluated by a cytopathologist. RESULTS US-FNA had a diagnostic sample rate of 92.2 % (centre 1: 95.9 %; centre 2: 87.2 %). US-FNA repetition after non-diagnostic samples provided a diagnosis in 86.3 % of cases. Sensitivity, specificity, positive and negative predictive values, and accuracy were 98.7 %, 100 %, 100 %, 75.5 %, and 98.7 %, respectively. The complication rate was 0.8 %. CONCLUSIONS Percutaneous US-FNA is a sensitive, accurate and safe method for the invasive diagnosis of solid pancreatic neoplasms. The use of aspiration needles and the on-site presence of a cytopathologist may lead to a high rate of diagnostic samples, thus reducing the need for US-FNA repetition. KEY POINTS • Percutaneous ultrasound-guided fine-needle aspiration of pancreatic neoplasms is sensitive and accurate. • The short-term complication rate of percutaneous ultrasound-guided fine-needle aspiration is low. • Technical aspects may influence the rate of diagnostic samples.

Abstract
BACKGROUND Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is a useful tool for the diagnosis of suspected abdominal or mediastinal neoplastic lesions. AIM To evaluate the impact of EUS-FNA and multidisciplinary approach on the diagnostic work-up and therapeutic management of patients with abdominal or mediastinal neoplastic lesions. PATIENTS AND METHODS One hundred and twenty patients (69 men, median age 65 years) with a suspected abdominal or mediastinal neoplastic mass at computed tomography or MRI underwent EUS-FNA. All EUS-FNA findings and clinical data were evaluated by a multidisciplinary team (oncologists, surgeons, and gastroenterologists). EUS-FNA findings were compared with the final diagnosis made by histological evaluation of the surgical specimen or clinical outcome at follow-up. RESULTS A correct diagnosis was obtained by EUS-FNA in 96/120 patients (80%), indicating benignancy of the lesion in 21 (18%) cases and confirming malignancy in 75 (62%). On the basis of EUS-FNA findings, chemotherapy was tailored in 57/75 (76%) patients with malignancy whereas the surgical strategy was changed in 21/120 (18%) of patients. Overall, the diagnostic accuracy of EUS-FNA was 85%. A multidisciplinary team approach enabled a correct diagnosis in patients in whom EUS-FNA was nondiagnostic and to identify five cases with false-negative EUS-FNA findings. CONCLUSION EUS-FNA has a relevant impact on the management of suspected abdominal or mediastinal neoplastic lesions. A multidisciplinary team approach enables to overcome the EUS-FNA methodological limitations. The combination of EUS-FNA and multidisciplinary team approach could help to diagnose and tailor therapeutic options in such patients.
