Diagnostic performance of endoscopic tissue acquisition for pancreatic ductal adenocarcinoma in the PREOPANC and PREOPANC-2 trials. HPB (Oxford) 2023; 25:1161-1168. [PMID: 37211461 DOI: 10.1016/j.hpb.2023.04.018] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Revised: 02/07/2023] [Accepted: 04/30/2023] [Indexed: 05/23/2023]
Abstract
BACKGROUND Neoadjuvant treatment for pancreatic ductal adenocarcinoma (PDAC) has increased, necessitating histopathologic confirmation of cancer. This study evaluates the performance of endoscopic tissue acquisition (TA) procedures for borderline resectable and resectable PDAC. METHODS Pathology reports of patients included in two nationwide randomized controlled trials (PREOPANC and PREOPANC-2) were reviewed. The primary outcome was sensitivity for malignancy (SFM), considering both "suspicious for" and "malignant" as positive. Secondary outcomes were rate of adequate sampling (RAS) and diagnoses other than PDAC. RESULTS Overall, 892 endoscopic procedures were performed in 617 patients, including endoscopic ultrasonography (EUS)-guided TA in 550 (89.1%), endoscopic retrograde cholangiopancreatography (ERCP)-guided brush cytology in 188 (30.5%), and periampullary biopsies in 61 patients (9.9%). The SFM was 85.2% for EUS, 88.2% for repeat EUS, 52.7% for ERCP, and 37.7% for periampullary biopsies. The RAS ranged 94-100%. Diagnoses other than PDAC were other periampullary cancers in 24 (5.4%), premalignant disease in five (1.1%), and pancreatitis in three patients (0.7%). CONCLUSIONS EUS-guided TA of patients with borderline resectable and resectable PDAC included in RCTs had an SFM above 85% for both first and repeat procedures, meeting international standards. Two percent had false positive result for malignancy and 5% had other (non-PDAC) periampullary cancers.

Diagnostic Yield of Repeat Endoscopic Ultrasound-Guided Fine Needle Biopsy for Solid Pancreatic Lesions. Cancers (Basel) 2023; 15:3745. [PMID: 37509406 PMCID: PMC10378084 DOI: 10.3390/cancers15143745] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2023] [Revised: 07/06/2023] [Accepted: 07/19/2023] [Indexed: 07/30/2023] Open
Abstract
PATIENTS AND METHODS we performed a retrospective case-control study, including cases with repeat EUS FNB for a solid pancreatic lesion, matched on a 1:2 ratio on age, sex, tumor location and presence of chronic pancreatitis with cases diagnosed on the first EUS FNB. RESULTS thirty-four cases and 68 controls were included in the analysis. Diagnostic accuracies were 80% and 88% in the repeat and single EUS FNB groups, respectively (p = 0.824). The second EUS FNB had a sensitivity of 80%, a specificity of 75%, a positive predictive value of 96%, and a negative predictive value of 33%. Of the 34 patients in the repeat EUS FNB group, 25 (74%) had a positive diagnosis with the second EUS FNB, 4 (12%) after surgery due to a second negative EUS FNB, 4 (12%) during clinical follow-up, and 1 (3%) after a third EUS FNB. Of the 25 patients diagnosed on the repeat EUS FNB, 17 (68%) had pancreatic adenocarcinomas, 2 (8%) neuroendocrine tumors, 2 (8%) other autoimmune pancreatitis, 2 (8%) chronic pancreatitis nodules, 1 (4%) renal cancer metastasis, and 1 (4%) other malignant diagnostic. There were no complications reported after the second EUS FNB in this study. CONCLUSION repeat EUS FNB made a diagnosis in three fourths of patients with solid pancreatic lesions and a first negative EUS FNB, with 26% of benign lesions. This supports the repetition of EUS FNB sampling in this clinical situation.

Efficacy of Contrast-Enhanced Endoscopic Ultrasonography for the Diagnosis of Pancreatic Tumors. Diagnostics (Basel) 2022; 12:diagnostics12061311. [PMID: 35741121 PMCID: PMC9222168 DOI: 10.3390/diagnostics12061311] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Revised: 05/21/2022] [Accepted: 05/23/2022] [Indexed: 02/04/2023] Open
Abstract
Endoscopic ultrasound can be useful for obtaining detailed diagnostic images for pancreatic disease. Contrast-enhanced harmonic endoscopic ultrasound has allowed to demonstrate not only microvasculature but also real perfusion imaging using second-generation contrast agents. Furthermore, endoscopic ultrasound fine-needle aspiration cytology and histology have become more ubiquitous; however, the risk of dissemination caused by paracentesis has yet to be resolved, and the application of less invasive contrast-enhanced endoscopic ultrasound for the differential diagnosis of pancreatic tumors has been anticipated. Contrast-enhanced harmonic endoscopic ultrasound can contribute to the differential diagnosis of pancreatic tumors.

Abstract
Endoscopic ultrasonography‐guided tissue acquisition (EUS‐TA) is now an established technique to obtain the pathological diagnosis of solid pancreatic lesions (SPLs), but the diagnosis of small SPLS by EUS‐TA can still be difficult. We conducted a literature review and a meta‐analysis on the diagnostic yield of EUS‐TA according to the tumor size. In a meta‐analysis of 33 studies with 6883 cases, a pooled odds ratio (OR) of sensitivity was significantly higher in SPLs of >20 mm (OR 1.64, p = 0.02) and in SPLs of >10 mm (OR 3.05, p = 0.01), but not in SPLs of >30 mm (OR 1.18, p = 0.46). The meta‐analysis of accuracy also showed a similar trend: OR of 1.59 in SPLs of >20 mm (p < 0.01) and OR of 3.27 in SPLs of >10 mm (p < 0.01) and OR of 1.03 in SPLs of >30 mm (p = 0.87). The use of a 25‐gauge needle tended to improve sensitivity in small SPLs, though not statistically significant: OR of 1.25 and 2.82 in studies with and without a 25‐gauge needle (p = 0.08). The use of fine needle biopsy needles, slow pull method, and rapid on‐site evaluation did not significantly improve sensitivity in small SPLs. EUS‐TA for small SPLs, especially neuroendocrine neoplasms, is reported to have a high risk of adverse events. In summary, the diagnostic yield and safety of EUS‐TA for small (<20 mm) SPLs still needs improvement, and the best needle and technique for small SPLs should be further investigated.

Abstract
As the burden of liver disease in the general populace steadily increases, so does the need for both advanced diagnostic and treatment options. Endoscopic ultrasound is a reliable diagnostic and therapeutic method that has an established role, foremost in pancreatobiliary pathology. This paper aims to summarize the growing role of endoscopic ultrasound in hepatology based on the search of the current literature. A number of applications of endoscopic ultrasound are reviewed, including both noninvasive methods and tissue acquisition in focal and diffuse liver disease, portal hypertension measurement, detection and management of gastric and esophageal varices, treatment of focal liver lesions and staging of pancreatobiliary malignancies, treatment of cystic and solid liver lesions, as well as liver abscess drainage. Both hepatologists and endoscopists should be aware of the evolving role of endoscopic ultrasound in liver disease. The inherent invasive nature of endoscopic examination limits its use to a targeted population identified using noninvasive methods. Endoscopic ultrasound is one the most versatile methods in gastroenterology, allowing immediate access with detection, sampling, and treatment of digestive tract pathology. Further expansion of its use in hepatology is immanent.

Abstract
Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is a sensitive and specific method for diagnosing cancer in solid pancreatic masses. However, some cases receive indeterminate atypical diagnoses, which creates management dilemmas. In the 2014 Papanicolaou Society of Cytopathology (PSC) standardized guidelines for pancreatobiliary cytology, specimens in the "Atypical" category show a spectrum of architectural and/or cellular changes beyond normal or reactive, but, quantitatively or qualitatively, insufficient for classification as neoplastic (benign/other), suspicious or positive for malignancy. Implementation of the PSC system decreased atypical diagnoses, particularly for cystic lesions, and redistributed many cases into benign and neoplastic categories. Because no set cytologic criteria exist for the "Atypical" category there is wide variability in its use, and its frequency ranges from 0%-16% (mean 6%). It consists of a heterogeneous mix of cases that occur because of preanalytic, lesion-specific (low cellularity, necrosis, cystic, reactive and premalignant changes), to pathologist-dependent factors (experience, expertise, training and institutional case volume). Outcomes of atypical diagnoses in solid pancreatic masses range from benign to premalignant and malignant and include reactive atypia in pancreatitis, well differentiated adenocarcinoma, and non-ductal malignancies. The associated risk of malignancy (ROM) ranges from 28%-100%, with an overall intermediate ROM in large-scale studies. Cytopathologists and institutions should monitor and keep their personal and/or laboratory's atypical rates low by judiciously using rapid onsite evaluation, ancillary studies, consensus or expert review, as well as correlation with clinical and radiologic findings. Early repeat EUS-FNA is indicated for unresolved cases.

Abstract
BACKGROUND AND AIMS EUS-guided FNA (EUS-FNA) is the criterion standard for the diagnosis of solid pancreatic lesions. Several studies assessed the role of repeat EUS-FNA (rEUS-FNA) after an inconclusive examination. Our aim was to evaluate the pooled diagnostic accuracy of rEUS-FNA after a nondiagnostic result. METHODS We conducted systematic research on electronic databases (Medline, PubMed, EMBASE) and a meta-analysis to obtain pooled sensitivity, specificity, positive and negative likelihood ratio, and diagnostic odds ratio. A summary receiver operating characteristic curve was used to calculate area under the curve. Subgroup analysis was used to assess the role of rapid on-site evaluation (ROSE). RESULTS Twelve studies (505 patients) were included. Sensitivity was 77% (66%-86%), specificity 98% (78%-100%), and positive and negative predictive values 99% (98%-100%) and 61 (60%-63%), respectively. At 73% of disease prevalence (pretest probability), positive rEUS-FNA increased the disease probability to 99%, whereas a negative result decreased the disease probability to 39%. The sensitivity was 83% (64%-93%) and specificity 98% (80%-100%) when ROSE was available and 65% (57%-73%) and 94% (31%-100%) when not available. The number needed to diagnose was 1.2 (1.1-2.3) and 1.7 (1.4-8.3) in ROSE-positive and ROSE-negative cases, respectively. The number of correctly diagnosed cases increased from 6 (1-7) to 8 (4-9) of 10 patients without and with ROSE, respectively. CONCLUSIONS This study objectively substantiated the added value of rEUS-FNA for the diagnosis of solid pancreatic masses in cases of a previous nondiagnostic or inconclusive result. Moreover, our data suggested that ROSE may be beneficial in this setting, because it increased the proportion of definitive diagnoses.

Abstract
BACKGROUND Despite numerous investigations, we still do not have a specific marker for pancreatic ductal adenocarcinoma. Only guideline-recommended biomarker for pancreatic ductal adenocarcinoma is the CA19-9, but it is also present in other gastrointestinal diseases. IMP3 is a new potential biomarker that is over-expressed in some cancers. The aims of our study were (1) to assess IMP3 in benign pancreatic lesions and pancreatic cancer, and (2) to estimate its concentrations in localized and advanced pancreatic cancer. PATIENTS AND METHODS Seventy-five patients with solid pancreatic lesions who underwent EUS-FNA were included. Patients were divided into three groups: benign lesions, cancer localized only on the pancreas, and patients with advanced pancreatic cancer (locally advanced or with distal metastases). Immunoreactivity of IMP3 was assessed on cytological smears sampled by endoscopic ultrasound. RESULTS IMP3 was expressed in 89% of the patients with pancreatic cancer and not in benign lesions. Stronger expression of IMP3 protein and stage of the pancreatic cancer was statistically significant. IMP3 was expressed in all localized cancers and in 85% of patients with advanced pancreatic cancer. In the subgroup with locally advanced cancer, IMP3 was expressed in 88%, and in 83% of patients in the subgroup with distal metastasis (P = 0.007). In the present study, sensitivity was 89%, specificity 100%, with positive predictive value of 100% and negative predictive value of 63%. CONCLUSION There is a positive correlation between IMP3 expression and TNM stages of the pancreatic cancer. Higher expression of IMP3 on EUS-FNA specimens can suggest poorer prognosis.

Abstract
Background Endoscopic ultrasonography guided fine needle aspiration (EUS-FNA) is a well-established technique for diagnosing pancreatic malignancy. In general, tissue of pancreatic head and uncinate process lesions is obtained via a transduodenal approach. However, this tissue-acquisition modality is not applicable in cases of pyloric obstruction and duodenal bulb ulceration. The aim of this study is to determine the feasibility and safety of a novel EUS-guided transgastric trans-portal system FNA in the diagnosis of pancreatic head and uncinate process cancer. Methods This study retrospectively analyzed 26 consecutive inpatient patients who had undergone EUS-FNA for highly suspected malignancy of pancreatic head or uncinate process between December 2013 and December 2018. EUS-guided transgastric trans-portal vein (trans-PV, n=2) or trans-superior mesenteric vein (trans-SMV, n=24) FNA was performed in the patients under conscious sedation. Feasibility, diagnostic yield and complication rates of the technique were evaluated. Results Specimens obtained by EUS-guided transgastric trans-portal system FNA were adequate for cytological evaluation in all 26 patients. Cytological diagnosis of adenocarcinoma was established in 22 patients, while the remaining 4 patients were negative. The diagnostic accuracy, sensitivity and specificity were 92.3%, 91.7% and 100% respectively. No immediate or delayed procedure-related complications were observed. Conclusions EUS-guided transgastric trans-portal system FNA is a feasible and probably safe method for diagnosing pancreatic head and uncinate process malignancy. Careful selection of the potential candidates and close periprocedural observation are mandatory.

Abstract
OBJECTIVES to determine the diagnostic yield of endoscopic ultrasonography-guided fine-needle aspiration (EUS-FNA) for suspected pancreatic malignancy. As well as to identify factors that affect the incidence of false-negative cases and evaluate the value of repeated EUS-FNA in patients with inconclusive results. METHODS we retrospectively evaluated the data of patients who underwent EUS-FNA due to a suspected pancreatic malignancy in our hospital from January 2015 to December 2016. RESULTS a total of 194 EUS-FNA procedures performed and 175 cases were analyzed. The overall sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy were 83.4% (151/181), 100% (13/13), 100% (151/151), 30.2% (13/43), and 84.5% (164/194), respectively. The combination of cytological and histological examination significantly increased the diagnostic performance compared to either method alone. The diagnostic sensitivity in metastatic tumors was significantly lower than that for adenocarcinoma. EUS-FNA performed using standard needles combined with the "slow-pull" technique had a lower sensitivity than other methods. According to the multivariate analysis, neither the combination of needle type and suction technique nor final diagnosis were independent factors that affected the diagnostic sensitivity. The sensitivity of repeated EUS-FNA was 50.0% (8/16). Definitive results after a repeated puncture were more likely for pancreatic body and tail masses, heterogeneous lesions and poorly demarcated lesions. However, the difference was not significant. CONCLUSIONS EUS-FNA was accurate for the evaluation of a suspected pancreatic malignancy. Metastatic tumors and the use of a standard needle in combination with the slow-pull technique may increase the incidence of false-negative results. Repeated EUS-FNA has limited value but should be considered for selected cases where the suspicion of malignancy persists.

Cytopathological results of initial endoscopic ultrasound-guided fine needle aspiration for primary mass and prognosis in pancreatic cancer patients. Cytopathology 2018; 30:173-178. [PMID: 30570774 DOI: 10.1111/cyt.12675] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2018] [Revised: 11/20/2018] [Accepted: 12/02/2018] [Indexed: 01/24/2023]
Abstract
OBJECTIVES Clinical outcomes remain unclear in patients suspected of having pancreatic cancer with indeterminate endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) results. This work aimed to investigate the prognosis of pancreatic cancer patients with indeterminate findings at initial EUS-FNA. METHODS Findings in all patients who underwent EUS-FNA for suspected pancreatic cancer between 2008 and 2015 at the National Cancer Center, Korea, were retrospectively reviewed. A final diagnosis of pancreatic ductal adenocarcinoma was based on pathology reports. RESULTS Of the 144 patients evaluated, 113 (78%) were diagnosed as being positive/suspicious for malignancy on cytological evaluation and 31 (22%) as having atypia/negative/non-diagnostic findings at initial EUS-FNA but subsequently diagnosed with pancreatic ductal adenocarcinoma. Tumour size, clinical stage and treatment modalities did not differ significantly between these two groups. Median overall survival was significantly shorter in patients diagnosed (11.3 ± 0.74 months; 95% confidence interval [CI], 9.4-12.8 months) than non-diagnosed (16.9 ± 2.34 months; 95% CI, 12.0-17.4 months) on initial EUS-FNA (P = .024). Multivariate Cox regression analysis showed that a non-diagnosis on initial EUS-FNA was independently associated with better overall survival (hazard ratio, 0.58; 95% CI, 0.38-0.88; P = .011). CONCLUSIONS Non-diagnostic results on initial EUS-FNA of a primary mass may be associated with better prognosis in patients with pancreatic cancer.

Abstract
AIM To evaluate the efficacy of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) of pancreatic head cancer when pushing (push method) or pulling the echoendoscope (pull method). METHODS Overall, 566 pancreatic cancer patients had their first EUS-FNA between February 2001 and December 2017. Among them, 201 who underwent EUS-FNA for pancreatic head lesions were included in this study. EUS-FNA was performed by the push method in 85 patients, the pull method in 101 patients and both the push and pull methods in 15 patients. After propensity score matching (age, sex, tumor diameter, and FNA needle), 85 patients each were stratified into the push and pull groups. Patient characteristics and EUS-FNA-related factors were compared between the two groups. RESULTS Patient characteristics were not significantly different between the two groups. The distance to lesion was significantly longer in the push group than in the pull group (13.9 ± 4.9 mm vs 7.0 ± 4.9 mm, P < 0.01). The push method was a significant factor influencing the distance to lesion (≥ median 10 mm) (P < 0.01). Additionally, tumor diameter ≥ 25 mm (OR = 1.91, 95%CI: 1.02-3.58, P = 0.043) and the push method (OR = 1.91, 95%CI: 1.03-3.55, P = 0.04) were significant factors contributing to the histological diagnosis of malignancy. CONCLUSION The pull method shortened the distance between the endoscope and the lesion and facilitated EUS-FNA of pancreatic head cancer. The push method contributed to the histological diagnosis of pancreatic head cancer using EUS-FNA specimens.

Abstract
Pancreatic cancer is a dismal disease with an increasing incidence. Despite the majority of patients are not candidates for curative surgery, a subgroup of patients classified as borderline resectable pancreatic cancer can be selected in whom a sequential strategy of neoadjuvant therapy followed by surgery can provide better outcomes. Multidisciplinary approach and surgical pancreatic expertise are essential for successfully treating these patients. However, the lack of consensual definitions and therapies make the results of studies very difficult to interpret and hard to be implemented in some settings. In this article, we review the challenges of borderline resectable pancreatic cancer, the complexity of its management and controversies and point out where further research and international cooperation for a consensus strategy is urgently needed.

Diagnostic value of CA19.9, circulating tumour DNA and circulating tumour cells in patients with solid pancreatic tumours. Br J Cancer 2017; 117:1017-1025.

Abstract
Background: The direct comparison of CA19.9, circulating tumour cells (CTCs) and circulating tumour DNA (ctDNA) using endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has never been performed for the diagnosis of solid pancreatic tumours (SPTs). Methods: We included 68 patients with a SPT referred for EUS-FNA. CTCs were analysed using size-based platform and ctDNA using digital PCR. The sensitivity, specificity, negative and positive predictive values were evaluated for each marker and their combination. Results: SPTs corresponded to 58 malignant tumours (52 pancreatic adenocarcinoma (PA) and 6 others) and 10 benign lesions. The sensitivity and specificity for PA diagnosis were 73% and 88% for EUS-FNA, 67% and 80% for CTC, 65% and 75% for ctDNA and 79% and 93% for CA19.9, respectively. The positivity of at least 2 markers was associated with a sensitivity and specificity of 78% and 91%, respectively. CtDNA was the only marker associated with overall survival (median 5.2 months for ctDNA+ vs 11.0 months for ctDNA−, P=0.01). Conclusions: CA19.9 alone and in combination with ctDNA and/or CTC analysis may represent an efficient method for diagnosing PA in patients with SPTs. Further studies including a larger cohort of patients with both malignant and benign lesions will be necessary to confirm these promising results.

Abstract
BACKGROUND Increasing numbers of incidental pancreatic lesions are being detected each year. Accurate characterisation of pancreatic lesions into benign, precancerous, and cancer masses is crucial in deciding whether to use treatment or surveillance. Distinguishing benign lesions from precancerous and cancerous lesions can prevent patients from undergoing unnecessary major surgery. Despite the importance of accurately classifying pancreatic lesions, there is no clear algorithm for management of focal pancreatic lesions. OBJECTIVES To determine and compare the diagnostic accuracy of various imaging modalities in detecting cancerous and precancerous lesions in people with focal pancreatic lesions. SEARCH METHODS We searched the CENTRAL, MEDLINE, Embase, and Science Citation Index until 19 July 2016. We searched the references of included studies to identify further studies. We did not restrict studies based on language or publication status, or whether data were collected prospectively or retrospectively. SELECTION CRITERIA We planned to include studies reporting cross-sectional information on the index test (CT (computed tomography), MRI (magnetic resonance imaging), PET (positron emission tomography), EUS (endoscopic ultrasound), EUS elastography, and EUS-guided biopsy or FNA (fine-needle aspiration)) and reference standard (confirmation of the nature of the lesion was obtained by histopathological examination of the entire lesion by surgical excision, or histopathological examination for confirmation of precancer or cancer by biopsy and clinical follow-up of at least six months in people with negative index tests) in people with pancreatic lesions irrespective of language or publication status or whether the data were collected prospectively or retrospectively. DATA COLLECTION AND ANALYSIS Two review authors independently searched the references to identify relevant studies and extracted the data. We planned to use the bivariate analysis to calculate the summary sensitivity and specificity with their 95% confidence intervals and the hierarchical summary receiver operating characteristic (HSROC) to compare the tests and assess heterogeneity, but used simpler models (such as univariate random-effects model and univariate fixed-effect model) for combining studies when appropriate because of the sparse data. We were unable to compare the diagnostic performance of the tests using formal statistical methods because of sparse data. MAIN RESULTS We included 54 studies involving a total of 3,196 participants evaluating the diagnostic accuracy of various index tests. In these 54 studies, eight different target conditions were identified with different final diagnoses constituting benign, precancerous, and cancerous lesions. None of the studies was of high methodological quality. None of the comparisons in which single studies were included was of sufficiently high methodological quality to warrant highlighting of the results. For differentiation of cancerous lesions from benign or precancerous lesions, we identified only one study per index test. The second analysis, of studies differentiating cancerous versus benign lesions, provided three tests in which meta-analysis could be performed. The sensitivities and specificities for diagnosing cancer were: EUS-FNA: sensitivity 0.79 (95% confidence interval (CI) 0.07 to 1.00), specificity 1.00 (95% CI 0.91 to 1.00); EUS: sensitivity 0.95 (95% CI 0.84 to 0.99), specificity 0.53 (95% CI 0.31 to 0.74); PET: sensitivity 0.92 (95% CI 0.80 to 0.97), specificity 0.65 (95% CI 0.39 to 0.84). The third analysis, of studies differentiating precancerous or cancerous lesions from benign lesions, only provided one test (EUS-FNA) in which meta-analysis was performed. EUS-FNA had moderate sensitivity for diagnosing precancerous or cancerous lesions (sensitivity 0.73 (95% CI 0.01 to 1.00) and high specificity 0.94 (95% CI 0.15 to 1.00), the extremely wide confidence intervals reflecting the heterogeneity between the studies). The fourth analysis, of studies differentiating cancerous (invasive carcinoma) from precancerous (dysplasia) provided three tests in which meta-analysis was performed. The sensitivities and specificities for diagnosing invasive carcinoma were: CT: sensitivity 0.72 (95% CI 0.50 to 0.87), specificity 0.92 (95% CI 0.81 to 0.97); EUS: sensitivity 0.78 (95% CI 0.44 to 0.94), specificity 0.91 (95% CI 0.61 to 0.98); EUS-FNA: sensitivity 0.66 (95% CI 0.03 to 0.99), specificity 0.92 (95% CI 0.73 to 0.98). The fifth analysis, of studies differentiating cancerous (high-grade dysplasia or invasive carcinoma) versus precancerous (low- or intermediate-grade dysplasia) provided six tests in which meta-analysis was performed. The sensitivities and specificities for diagnosing cancer (high-grade dysplasia or invasive carcinoma) were: CT: sensitivity 0.87 (95% CI 0.00 to 1.00), specificity 0.96 (95% CI 0.00 to 1.00); EUS: sensitivity 0.86 (95% CI 0.74 to 0.92), specificity 0.91 (95% CI 0.83 to 0.96); EUS-FNA: sensitivity 0.47 (95% CI 0.24 to 0.70), specificity 0.91 (95% CI 0.32 to 1.00); EUS-FNA carcinoembryonic antigen 200 ng/mL: sensitivity 0.58 (95% CI 0.28 to 0.83), specificity 0.51 (95% CI 0.19 to 0.81); MRI: sensitivity 0.69 (95% CI 0.44 to 0.86), specificity 0.93 (95% CI 0.43 to 1.00); PET: sensitivity 0.90 (95% CI 0.79 to 0.96), specificity 0.94 (95% CI 0.81 to 0.99). The sixth analysis, of studies differentiating cancerous (invasive carcinoma) from precancerous (low-grade dysplasia) provided no tests in which meta-analysis was performed. The seventh analysis, of studies differentiating precancerous or cancerous (intermediate- or high-grade dysplasia or invasive carcinoma) from precancerous (low-grade dysplasia) provided two tests in which meta-analysis was performed. The sensitivity and specificity for diagnosing cancer were: CT: sensitivity 0.83 (95% CI 0.68 to 0.92), specificity 0.83 (95% CI 0.64 to 0.93) and MRI: sensitivity 0.80 (95% CI 0.58 to 0.92), specificity 0.81 (95% CI 0.53 to 0.95), respectively. The eighth analysis, of studies differentiating precancerous or cancerous (intermediate- or high-grade dysplasia or invasive carcinoma) from precancerous (low-grade dysplasia) or benign lesions provided no test in which meta-analysis was performed.There were no major alterations in the subgroup analysis of cystic pancreatic focal lesions (42 studies; 2086 participants). None of the included studies evaluated EUS elastography or sequential testing. AUTHORS' CONCLUSIONS We were unable to arrive at any firm conclusions because of the differences in the way that study authors classified focal pancreatic lesions into cancerous, precancerous, and benign lesions; the inclusion of few studies with wide confidence intervals for each comparison; poor methodological quality in the studies; and heterogeneity in the estimates within comparisons.

Abstract
Background. There is a high incidence of inconclusive cytopathology at initial EUS-FNA (endoscopic ultrasound-guided fine-needle aspiration) for suspected malignant pancreatic lesions. To obtain appropriate preoperative or palliative chemotherapy for pancreatic cancer, definitive cytopathology is often required. The utility of repeat EUS-FNA is not well established. Methods. A retrospective cohort study was conducted evaluating the yield of repeat EUS-FNA in determining a cytological diagnosis in patients who had undergone a prior EUS-FNA for diagnosis of suspected malignant pancreatic lesions with inconclusive cytopathology. The wait times to the second procedure and to decisions regarding therapy were calculated. Results. Overall, 45 repeat EUS-FNA procedures were performed over seven years for suspected malignant pancreatic lesions. Cytopathological class (I to IV) changed between first and second EUS-FNA in 32 patients (71%). Of 34 patients with an initially nonconclusive diagnosis, 20 had a conclusive diagnosis (59%) on repeat EUS-FNA. The cumulative yield after repeat EUS-FNA for definite pancreatic adenocarcinoma was 7 (16%). The median time interval between first and second EUS-FNA was 31 (7-175) days. Conclusions. A substantial number of patients had a definitive diagnosis of adenocarcinoma on repeat FNA and were, therefore, subsequently able to access appropriate care.

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
Endoscopic ultrasonography-guided fine-needle aspiration (EUS-FNA) has been applied to pancreaticobiliary lesions since the 1990s and is in widespread use throughout the world today. We used this method to confirm the pathological evidence of the pancreaticobiliary lesions and to perform suitable therapies. Complications of EUS-FNA are quite rare, but some of them are severe. Operators should master conventional EUS observation and experience a minimum of 20-30 cases of supervised EUS-FNA on non-pancreatic and pancreatic lesions before attempting solo EUS-FNA. Studies conducted on pancreaticobiliary EUS-FNA have focused on selection of suitable instruments (e.g., needle selection) and sampling techniques (e.g., fanning method, suction level, with or without a stylet, optimum number of passes). Today, the diagnostic ability of EUS-FNA is still improving; the detection of pancreatic cancer (PC) currently has a sensitivity of 90%-95% and specificity of 95%-100%. In addition to PC, a variety of rare pancreatic tumors can be discriminated by conducting immunohistochemistry on the FNA materials. A flexible, large caliber needle has been used to obtain a large piece of tissue, which can provide sufficient histological information to be helpful in classifying benign pancreatic lesions. EUS-FNA can supply high diagnostic yields even for biliary lesions or peri-pancreaticobiliary lymph nodes. This review focuses on the clinical aspects of EUS-FNA in the pancreaticobiliary field, with the aim of providing information that can enable more accurate and efficient diagnosis.

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.

Abstract
BACKGROUND AND STUDY AIMS A variety of factors (needle type, needle passes, tumor location, cytological assessment, etc.) may influence the diagnostic accuracy of endoscopic ultrasound-guided fine-needle aspiration cytology (EUS-FNAC) from pancreatic tumors. Whereas most published studies report a diagnostic accuracy of > 80 % for EUS-FNAC, the results in routine settings are often considerably lower. This retrospective study aimed to define the effect of switching microscopic assessment from a standard pathology department to a highly specialized institute of cytology. PATIENTS AND METHODS A total of 63 patients underwent EUS-FNAC of solid or semisolid pancreatic masses. Specimens of the first consecutive 20 cases (Phase 1) were assessed by the local department of pathology. Then in Phase 2, involving another 43 subsequent cases, a specialized cytology laboratory examined all aspirates. All EUS-FNACs were performed in the same manner, using a 22-gauge needle. After cytological evaluation, all patients either underwent surgery or were followed up for at least 6 months. RESULTS Of the tumors, 56 were solid and 7 semisolid; the mean size was 30 mm. Sensitivity (sens.), specificity (spec.), positive predictive value (PPV), and negative predictive value (NPV) of EUS-FNAC were 38.5 % (95 %CI [confidence interval] 13.9 - 68.4 %), 100 % (59.0 - 100 %), 100 % (47.8 - 100 %), and 46.7 % (21.3 - 73.4 %) during Phase 1 versus 91.4 % (95 %CI 76.9 - 98.2 %), 100 % (63.1 - 100 %), 100 % (89.1 - 100 %), and 72.7 % (39.0 - 94.0 %) during Phase 2. CONCLUSION These results emphasize the considerable impact of a dedicated cytological evaluation on the results of EUS-FNAC.

Abstract
Endoscopic ultrasound is the most accurate imaging modality for the diagnosis of pancreatic cancer, and endoscopic ultrasound-guided fine needle injection has already been used for palliative interventions. Surgical resection is currently the standard treatment for pancreatic insulinoma. Medical treatment may be necessary for symptomatic patients with unresectable disease. Case reports have been published about the success of endoscopic ultrasound-guided alcoholic ablation, but it has not been reported previously in Hungarian literature. The authors present the history of an 83-year-old woman who was evaluated because of repeated hypoglycemic coma occurring during the night. Endosonographic image and laboratory findings (elevated serum insulin and chromogranin A) revealed pancreatic insulinoma. Because of severe comorbidities and high risk of surgical resection, the decision was made to ablate the insulinoma by endoscopic ultrasound-guided alcohol injection. A total of 3 mL 95% ethanol was injected into the tumor. Despite the discontinuation of the diazoxide therapy the hypoglycemic episodes disappeared. This case history confirms that endoscopic ultrasound-guided alcoholic ablation is a novel, minimal invasive alternative treatment for patients with pancreatic neuroendocrine tumors in whom surgery is not feasible.

Abstract
The role of endoscopic ultrasound (EUS) in evaluating pancreatic pathology has been well documented from the beginning of its clinical use. High spatial resolution and the close proximity to the evaluated organs within the mediastinum and abdominal cavity allow detection of small focal lesions and precise tissue acquisition from suspected lesions within the reach of this method. Fine needle aspiration (FNA) is considered of additional value to EUS and is performed to obtain tissue diagnosis. Tissue acquisition from suspected lesions for cytological or histological analysis allows, not only the differentiation between malignant and non-malignant lesions, but, in most cases, also the accurate distinction between the various types of malignant lesions. It is well documented that the best results are achieved only if an adequate sample is obtained for further analysis, if the material is processed in an appropriate way, and if adequate ancillary methods are performed. This is a multi-step process and could be quite a challenge in some cases. In this article, we discuss the technical aspects of tissue acquisition by EUS-guided-FNA (EUS-FNA), as well as the role of an on-site cytopathologist, various means of specimen processing, and the selection of the appropriate ancillary method for providing an accurate tissue diagnosis and maximizing the yield of this method. The main goal of this review is to alert endosonographers, not only to the different possibilities of tissue acquisition, namely EUS-FNA, but also to bring to their attention the importance of proper sample processing in the evaluation of various lesions in the gastrointestinal tract and other accessible organs. All aspects of tissue acquisition (needles, suction, use of stylet, complications, etc.) have been well discussed lately. Adequate tissue samples enable comprehensive diagnoses, which answer the main clinical questions, thus enabling targeted therapy.

Abstract
BACKGROUND Early detection of small pancreatic cancer is important because expected survival is markedly better for tumors ≤ 2 cm. A new endoscopic ultrasound-(EUS) guided biopsy needle with side fenestration has been recently developed to enable fine-needle biopsy (FNB) under EUS guidance. The aim of this study was to evaluate the outcome of EUS-FNB using a 22-gauge ProCore needle in solid pancreatic lesions ≤ 2 cm, in terms of diagnostic accuracy and yield. METHODS From January 2011 to December 2012, all consecutive EUS-guided tissue sampling of small pancreatic lesions (≤ 2 cm) were performed using 22-gauge ProCore needles; the data of these patients were analyzed retrospectively. RESULTS Sixty-eight patients with a mean age of 65.7 years were included. The mean lesion size was 16.5 mm (range 5-20). None of the patients developed complications. On pathological examination, the tissue retrieved was judged adequate in 58 out of 68 cases (85.3 %) and the presence of a tissue core was recorded in 36 out of 68 cases (52.9 %). The overall sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 80, 100, 100, 40, and 82 %, respectively. CONCLUSION Our results suggested that EUS-FNB of small pancreatic lesions using a 22-gauge ProCore needle is effective and safe, and supports our hypothesis that EUS-FNB is highly useful in establishing the nature of small pancreatic lesions.

Abstract
Autoimmune pancreatitis (AIP) must be differentiated from pancreatic carcinoma, and immunoglobulin (Ig)G4-related sclerosing cholangitis (SC) from cholangiocarcinoma and primary sclerosing cholangitis (PSC). Pancreatographic findings such as a long narrowing of the main pancreatic duct, lack of upstream dilatation, skipped narrowed lesions, and side branches arising from the narrowed portion suggest AIP rather than pancreatic carcinoma. Cholangiographic findings for PSC, including band-like stricture, beaded or pruned-tree appearance, or diverticulum-like outpouching are rarely observed in IgG4-SC patients, whereas dilatation after a long stricture of the bile duct is common in IgG4-SC. Transpapillary biopsy for bile duct stricture is useful to rule out cholangiocarcinoma and to support the diagnosis of IgG4-SC with IgG4-immunostaining. IgG4-immunostaining of biopsy specimens from the major papilla advances a diagnosis of AIP. Contrast-enhanced endoscopic ultrasonography (EUS) and EUS elastography have the potential to predict the histological nature of the lesions. Intraductal ultrasonographic finding of wall thickening in the non-stenotic bile duct on cholangiography is useful for distinguishing IgG4-SC from cholangiocarcinoma. Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is widely used to exclude pancreatic carcinoma. To obtain adequate tissue samples for the histological diagnosis of AIP, EUS-Tru-cut biopsy or EUS-FNA using a 19-gauge needle is recommended, but EUS-FNA with a 22-gauge needle can also provide sufficient histological samples with careful sample processing after collection and rapid motion of the FNA needles within the pancreas. Validation of endoscopic imaging criteria and new techniques or devices to increase the diagnostic yield of endoscopic tissue sampling should be developed.

Abstract
Pancreatic cancer is difficult to diagnose at an early stage and generally has a poor prognosis. Surgical resection is the only potentially curative treatment for pancreatic carcinoma. To improve the prognosis of this disease, it is essential to detect tumors at early stages, when they are resectable. The optimal approach to screening for early pancreatic neoplasia has not been established. The International Cancer of the Pancreas Screening Consortium has recently finalized several recommendations regarding the management of patients who are at an increased risk of familial pancreatic cancer. In addition, there have been notable advances in research on serum markers, tissue markers, gene signatures, and genomic targets of pancreatic cancer. To date, however, no biomarkers have been established in the clinical setting. Advancements in imaging modalities touch all aspects of the clinical management of pancreatic diseases, including the early detection of pancreatic masses, their characterization, and evaluations of tumor resectability. This article reviews strategies for screening high-risk groups, biomarkers, and current advances in imaging modalities for the early detection of resectable pancreatic cancer.

Abstract
BACKGROUND Rapid on-site evaluation (ROSE) has the potential to improve adequacy rates for endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) of solid pancreatic lesions, but its impact is context-dependent. No studies exist that summarize the relationship between ROSE, number of needle passes, and resulting adequacy rates. AIMS To analyze data from previous studies to establish if ROSE is associated with improved adequacy rates; to evaluate the relationship between ROSE, number of needle passes, and the resulting adequacy rates of EUS-FNA for solid pancreatic lesions. METHODS Systematic review and meta-analysis of studies reporting the adequacy rates for EUS-FNA of solid pancreatic lesions. RESULTS The search produced 3822 original studies, of which 70 studies met our inclusion criteria. The overall average adequacy rate was 96.2% (95% confidence interval: 95.5, 96.9). ROSE was associated with a statistically significant improvement of up to 3.5% in adequacy rates. There was heterogeneity in adequacy rates across all subgroups. No association between the assessor type and adequacy rates was found. Studies with ROSE have high per-case adequacy and a relatively high number of needle passes in contrast to non-ROSE studies. ROSE is an effect modifier of the relationship between number of needle passes and adequacy. CONCLUSIONS ROSE is associated with up to 3.5% improvement in adequacy rates for EUS-FNA of solid pancreatic lesions. ROSE assessor type has no impact on adequacy rates. ROSE is an effect modifier on the relationship between needle passes and per-case adequacy for EUS-FNA of solid pancreatic lesions.

Abstract
Endoscopic ultrasound guided (EUS) fine-needle aspiration (FNA) investigation of solid pancreatic lesions has been shown to have good sensitivity and specificity. Many lesions can be definitely classified as benign or malignant but some can only be cytologically classified as "atypical" or "suspicious for malignancy". Risk for malignancy in these indeterminate categories has not been well categorized. The cytology records of four University Medical centers were searched for all EUS guided FNAs of solid pancreatic lesions. All cases with a diagnosis of "atypical", or "suspicious for malignancy" were selected for analysis when histologic biopsy or over 18 months clinical follow-up was available. Two hundred and ninety-two cases with a diagnosis of "atypical" or "suspicious for malignancy" and adequate follow-up were obtained from the combined data of the four institutions. The percentage malignant for the categories "atypical" and "suspicious for malignancy" were 79.2 and 96.3%, respectively. If the category "atypical" was classified as benign and "suspicious for malignancy" was classified as malignant, the resulting positive predictive value was 96.3 (95% CI: 92.6-98.5) and the negative predictive value 20.8 (95% CI: 13.4-30.0). The categories of "atypical" and "suspicious for malignancy" stratify risk for malignancy in a fashion, which may aid in patient counseling and selection of follow-up protocols. Classification of "suspicious for malignancy" as malignant optimizes diagnostic sensitivity and specificity.

Abstract
Tissue acquisition plays a key role before treatment decision in most of oncological pathologies but also in several benign diseases. By offering tissue sampling, endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) has become an essential tool in the diagnostic processes. One of the reasons for the success of the technique is related to its excellent diagnostic performance. The diagnostic accuracy of EUS-FNA is above 80% for most of the usual indications. These performances are however dependent on some factors related to both the disease and patient's medical history but also related to medical staff expertise. Endoscopist needs to know how to reach a lesion but also how to efficiently acquire good tissue samples. This review aims to report general recommendations available in the literature for high quality EUS-FNA. Sample processing and sample interpretation also influence diagnostic accuracy of FNA. This paper includes a discussion on sample processing and benefits of the on-site pathology examination. It also provides the results reported in the literature of sample adequacy and diagnostic performance of EUS-FNA for most common indications: Pancreatic diseases, sub-mucosal lesion, mucosal thickenings, lymph nodes, cystic lesion and free fluids.

Abstract
The diagnostic yield of EUS-FNA depends on several factors, such as the experience of the endosonographer, the characteristics of the lesion, the clinical status of the patient, the size and type of needles, the methods of specimen preparation, as well as cytopathologist expertise. The endosonographic technique can be improved when several tips and tricks useful to overcome challenges of FNA are known. Technical challenges of FNA are related to the characteristics of the lesion and its surroundings, sonographic imaging, and limitations related to the needle. Several tips and tricks necessary to overcome them are presented in this review.

Abstract
BACKGROUND Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is currently the predominant method for obtaining a preoperative tissue diagnosis for pancreatic lesions suspicious for malignancy. The diagnostic sensitivity and specificity of EUS-FNA are well documented, but malignancy risk associated with the diagnostic categories proposed by the Papanicolaou Society of Cytopathology is poorly defined. METHODS The records of the Departments of Pathology at Duke University and the University of Utah were searched for all cases of EUS-FNA performed for the investigation of pancreatic lesions. All cases with follow-up surgical diagnosis or greater than 3 years of clinical follow-up were selected. Cytologic diagnostic categories were "nondiagnostic," "benign," "atypical (not otherwise specified)," "suspicious for malignancy," "neoplasm," and "malignant." Correlation of cytologic diagnosis with surgical and/or clinical follow-up was made and risk of malignancy calculated for each category. RESULTS Three hundred seventeen EUS-FNAs with adequate surgical or clinical follow-up were obtained. Risk of malignancy for nondiagnostic specimens was 21%;, benign specimens, 13%; atypical cases, 74%; suspicious for malignancy, 82%; the neoplasm category, 14%; and the malignant category, 97% CONCLUSIONS The cytologic categories proposed by the Papanicolaou Society of Cytopathology demonstrate an increasing risk for malignancy extending from benign to malignant. Aspirates designated benign have the lowest risk of malignancy (13%) and aspirates designated malignant the highest (97%). The proposed categorization scheme stratifies risk for malignancy giving useful information to clinicians treating patients with pancreatic lesions.

[PMID: 23983161 DOI: 10.1002/cncy.21340] [Citation(s) in RCA: 62] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2013] [Revised: 07/01/2013] [Accepted: 07/09/2013] [Indexed: 02/06/2023]
Abstract
BACKGROUND Rapid on-site evaluation (ROSE) for endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) biopsy of the pancreas provides immediate feedback regarding cellular adequacy to aid in obtaining a definitive diagnosis and has the potential to avoid repeat procedures. The objective of the current study was to measure the impact of ROSE service on the incidence of repeat EUS FNA biopsy procedures. METHODS Over a consecutive 3-year period, the pathology database at Washington University Medical Center was searched for patients with both an initial and subsequent EUS FNA biopsy demonstrating a solid lesion of the pancreas. These were divided temporally between the time before and after the introduction of ROSE service. Reports were reviewed and results were recorded. RESULTS A total of 379 patients underwent ROSE service and 377 patients did not. The percentage of repeat non-ROSE EUS FNA cases was 5.8% and the percentage of repeat ROSE EUS FNA cases was 2.9%. The use of the ROSE service was found to decrease the number of repeat procedures by approximately 50% (P = .024). For those patients who underwent a repeat EUS-FNA procedure, the ROSE service provided a higher rate of definitive diagnosis among patients undergoing repeat procedures (67%) versus the non-ROSE cohort (27%). CONCLUSIONS The use of ROSE for EUS-FNA biopsy of the pancreas was found to result in fewer patients undergoing repeat procedures. Patients who required a repeat procedure with the use of ROSE had a higher percentage of definitive diagnostic categorization on the repeat biopsy. Initial use of ROSE for EUS-FNA of solid pancreatic lesions was found to decrease the number of patients who required a repeat procedure.

Abstract
For tissue diagnosis of suspected pancreatic cancer, endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is the procedure of choice with high safety and accuracy profiles. However, about 10% of cytologic findings of EUS-FNA are inconclusive. In that situation, careful observation, surgical exploration, or alternative diagnostic tools such as bile duct brushing with endoscopic retrograde cholangiopancreatography or computed tomography-guided biopsy can be considered. However, some concerns and/or risks of these options render repeat EUS-FNA a reasonable choice. Repeated EUS-FNA may impose substantial clinical impact with low risk.

The frequency and cancer risk associated with the atypical cytologic diagnostic category in endoscopic ultrasound-guided fine-needle aspiration specimens of solid pancreatic lesions: a meta-analysis and argument for a Bethesda System for Reporting Cytopathology of the Pancreas. Cancer Cytopathol 2013; 121:620-8. [PMID: 23881871 DOI: 10.1002/cncy.21337] [Citation(s) in RCA: 38] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2013] [Revised: 06/13/2013] [Accepted: 06/17/2013] [Indexed: 01/03/2023]
Abstract
BACKGROUND The atypical cytologic diagnostic category is ambiguous and presents a management problem for pathologists and clinicians. This meta-analysis reviewed the frequency and cancer risk associated with atypical diagnoses in endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) specimens of solid pancreatic lesions. METHODS PubMed and Scopus were searched using the keywords "EUS-FNA" and "pancreas." Articles were screened focusing on studies of solid lesions. Studies with information regarding the frequency and outcomes of atypical diagnoses were included; the "suspicious" category was excluded from the analysis. The frequency of atypical diagnoses and the associated risk were calculated using the Comprehensive Meta-Analysis software. The authors assessed whether the following factors explained the heterogeneity of the studies: rapid on-site interpretation; type of reference standard; the study type, size, and site; and the frequency of inadequate, atypical, and positive categories. RESULTS A total of 23 studies with complete data regarding atypical diagnoses were identified, 12 of which had complete data available regarding outcomes. The frequency of the atypical category ranged from 1% to 14% (mean, 5.3%; 95% confidence interval, 4.1%-6.9%). The risk of malignancy associated with an atypical diagnosis ranged from 25% to 100% (mean, 58%; 95% confidence interval, 47%-69%). There was significant heterogeneity noted among the studies (I-squared, 62%; P = .0004). The frequency of the atypical category and its associated risk were found to be correlated only with the frequency of the specimens being positive for malignancy. CONCLUSIONS The rate of atypical diagnoses of the pancreas is similar to that of the thyroid but the risk of malignancy is higher. Significant heterogeneity exists among the studies reporting atypical diagnoses. There is a need for standardization of the reporting and management of atypical diagnoses in EUS-FNA specimens from the pancreas.

Abstract
The role of endoscopic ultrasound (EUS) in the diagnosis of biliary obstruction is well established, and emerging evidence suggests it may also play a therapeutic role. Differentiating between benign and malignant causes of biliary obstruction can be challenging, but EUS is a crucial tool in the armamentarium of the physician. Evolving technologies such as elastography and contrast enhancement may further supplement the diagnostic abilities of EUS. Therapeutic applications of EUS are evolving rapidly, and EUS-guided cholangiography may aid biliary decompression when endoscopic retrograde cholangiopancreatography (ERCP) has failed or is not possible.

Abstract
BACKGROUND Among many diagnostic criteria for autoimmune pancreatitis (AIP), the International Consensus Diagnostic Criteria (ICDC) first enabled us to diagnose and compare type 1 and type 2 AIP, which permitted tailoring individual diagnostic algorithms depending on local expertise. We compared them and validated ICDC with special reference to levels 1 and 2, and proposed a diagnostic algorithm for AIP in Japan. METHODS The diagnostic sensitivity of 5 major criteria (ICDC, Korean, Japanese-2011, Asian, and HISORt criteria) was compared, using 61 patients with AIP. Fifty six patients with pancreatic cancer served as a control. Pancreas imaging on computed tomography (CT) and endoscopic retrograde pancreatography (ERP) were independently evaluated by 3 pancreatologists (5, 10, and 20 years of career experience) and each diagnostic criterion of ICDC was validated with special reference to levels 1 and 2. RESULTS The sensitivities of 5 major criteria were 95.1% (ICDC), 90.2% (Korean), 86.9% (Japanese), 83.6% (Asian), and 83.6% (HISORt) with 100% of specificity in each. In the evaluation of pancreas imaging, diagnostic sensitivities of combination with CT and ERP in segmental/focal type AIP were significantly higher than single imaging (26% in CT (P < 0.01) or 35% in ERP (P < 0.05) vs 63% in CT + ERP), but not significantly different in the diffuse type. CONCLUSIONS Of the 5 criteria, ICDC is the most sensitive and useful for diagnosing AIP. We have proposed a diagnostic algorithm with CT for the diffuse type of AIP, and combination with CT + ERP followed by EUS-FNA for the segmental/focal type.

Abstract
Since its initial report in 1992, endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has now been incorporated into the diagnostic and staging algorithm for the evaluation of benign and malignant diseases of the gastrointestinal tract and of adjacent organs. Its introduction constitutes a major breakthrough in the endoscopic field and has gradually transformed EUS from a pure imaging modality into a more interventional. In addition, the possibility of collecting samples, providing a definitive cytological and/or histological evidence of the presence of malignancy, has strongly contributed to changing EUS from a subjective, highly operator dependant procedure into a more objective one. This article will review the instrumentation, technique and the most important clinical applications of EUS-FNA.

Abstract
BACKGROUND Accurate pre-operative imaging in pancreatic cancer helps avoid unsuccessful surgical explorations and forewarns surgeons regarding aberrant anatomy. This review aimed to determine the role of current imaging modalities in the diagnosis and determination of resectability of pancreatic and peri-ampullary adenocarcinomas. METHODS A systematic search of the scientific literature was carried out using EMBASE, PubMed/MEDLINE and the Cochrane Central Register of Controlled Trials for the years 1990 to 2011 to obtain access to all publications, especially randomized controlled trials, reporting on the diagnostic accuracy of ultrasonography, multi-detector computed tomography (MDCT), magnetic resonance imaging (MRI), endoscopic ultrasonography (EUS) or positron emission tomography (PET)-computed tomography (CT) and the evaluation of resectability of pancreatic and peri-ampullary adenocarcinomas. RESULTS Based on 66 articles analysed in the review, MDCT and MRI/MRCP have comparable sensitivity and specificity rates for diagnosis and staging of pancreatic cancers. EUS offers the best sensitivity and specificity rates for lesions <2 cm. Improved staging has been noted when PET-CT scans are added to pre-operative evaluation. CONCLUSIONS MDCT with angiography or MRI/MRCP should constitute the first imaging modality in suspected pancreatic adenocarcinomas. EUS is recommended for assessing lesions not clearly detected, but suspected, on CT/MRI and in tumours considered 'borderline resectable' on MDCT to assess vascular involvement. PET-CT in locally advanced lesions will help rule out distant metastases.

Abstract
BACKGROUND Preoperative diagnosis of solid pancreatic lesions remains challenging despite advancement in imaging technologies. EUS has the benefit of being a minimally invasive, well-tolerated procedure, although results are operator-dependent. The addition of FNA (EUS-guided FNA) provides samples for cytopathologic analysis, a major advantage over other imaging techniques. OBJECTIVE To determine the diagnostic accuracy of EUS-FNA for pancreatic cancer. DESIGN This is a meta-analysis of published studies assessing the diagnostic capability of EUS-FNA. Relevant studies were identified via MEDLINE and were included if they used a reference standard of definitive surgical histology or clinical follow-up of at least 6 months. MAIN OUTCOME MEASUREMENTS Data from selected studies were analyzed by using test accuracy meta-analysis software, providing a pooled value for sensitivity, specificity, diagnostic odds ratio, and summary receiver operating characteristic curve. Cytology results were classified as inadequate, benign, atypical, suspicious, or malignant. Predefined subgroup analysis was performed. RESULTS Thirty-three studies published between 1997 and 2009 were included, with a total number of 4984 patients. The pooled sensitivity for malignant cytology was 85% (95% confidence interval [CI], 84-86), and pooled specificity was 98% (95% CI, 0.97-0.99). If atypical and suspicious cytology results were included to determine true neoplasms, the sensitivity increased to 91% (95% CI, 90-92); however, the specificity was reduced to 94% (95% CI, 93-96). The diagnostic accuracy of EUS-FNA was enhanced in prospective, multicenter studies. LIMITATION Publication bias was not a significant determinant of pooled accuracy. CONCLUSION This meta-analysis demonstrates that EUS-FNA is a highly accurate diagnostic test for solid neoplasms of the pancreas and should be considered when algorithms for investigating solid pancreatic lesions are being planned.

Abstract
To determine the variety of chemotherapy drugs administrable for malignant pancreatic neoplasm as a result of typification with endoscopic ultrasonography-fine needle aspiration (EUS-FNA). A retrospective assessment, in one center, over a period of 1 year. Only malignant pancreatic neoplasm diagnosed by EUS-FNA was recorded. Benign (serous cystic neoplasm) and potentially malignant lesions (mucinous cystic neoplasm and intraductal papillary-mucinous neoplasm) were excluded. Medical data were recorded and Oncological Pharmacy records were studied. Ductal adenocarcinoma were detected in 17 patients (N = 17/22), 2 of them with adenocarcinoma in signet ring and 1 with mucinous adenocarcinoma. The primary therapies used were as follows: Whipple pancreaticoduodenectomy (3), biliary stent by endoscopic retrograde cholangiopancreatography (3), radiological transhepatic percutaneous stent (2), intestinal bypass (2), and a gastric stent (1). The adjuvant drugs used were gemcitabine (10), erlotinib (3), and cetuximab (1), and also radiotherapy was used (1). An unresectable squamous cell carcinoma (N = 1) of the tail was detected, and gemcitabine + vinorelbine + fluorouracil + cisplatin used. Nonfunctioning neuroendocrine tumors were seen in 3 (N = 3) cases and long-acting somatostatin analogues were used (1); the remaining 2 patients showed resectable tumors and were resected accordingly. A metastasis to the pancreatic head in a hepatocellular carcinoma was found in 1 patient (N = 1), allowing specific treatment with sorafenib. Histopathologic analysis with EUS-FNA implies a variety of different treatments. Optimal management was achieved as a result of improved diagnosis, with the advent of new molecular genetic diagnostic methods facilitating the design of specific new therapy and neoadjuvant targeting strategies.

Abstract
BACKGROUND & AIMS Preoperative differential diagnosis of pancreatic ductal adenocarcinoma (PDAC) and focal masses in patients with chronic pancreatitis (CP) can be challenging. There are fine differences in the vascularization of these lesions; ultrasound contrast agents can aid in their differentiation. We evaluated the value of software-aided quantitative analysis of transabdominal contrast-enhanced ultrasonography for differential diagnosis of PDAC vs focal masses. METHODS Sixty patients for whom it was not possible to differentiate between an inflammatory focal lesion of the pancreas and a pancreatic carcinoma underwent contrast-enhanced ultrasonography with a second-generation contrast agent. Time-intensity curves were obtained for all exams in 2 regions of interest within the lesion and within the normal pancreatic tissue. Images were processed using Axius ACQ software; the following parameters were obtained: maximum intensity, arrival time, time-to-peak, and area under the curve. Absolute values and differences between the lesion and the normal tissue were evaluated. RESULTS Histology analysis revealed 45 PDACs and 15 inflammatory masses in patients with CP. Time-dependent parameters (arrival time and time to peak) were significantly longer in PDACs compared to focal masses. Although markedly lower than in healthy pancreata, the maximum intensity and area under the curve parameters were not significantly different between PDACs and focal lesions in patients with CP. CONCLUSIONS In cases of CP, PDAC and focal masses exhibit different perfusion patterns at a capillary level that can be visualized using the small microbubbles of ultrasound contrast agents. Contrast quantification software supplements a subjective visual assessment with objective criteria to facilitate the differential diagnosis of focal lesions in pancreatic cancer and chronic pancreatitis.

Blinded prospective comparison of the performance of 22-gauge and 25-gauge needles in endoscopic ultrasound-guided fine needle aspiration of the pancreas and peri-pancreatic lesions. Dig Dis Sci 2009; 54:2274-81.

Abstract
BACKGROUND Both 22- and 25-gauge needles are used for endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) of lesions, yet limited data exist on whether either offers an advantage over the other in terms of specimen cellularity and quality. AIM The aim of this study was to compare sample quality for 22- and 25-gauge needles in EUS-guided FNA of pancreatic and peri-pancreatic lesions. METHODS Between October 2005 and June 2006, 12 patients with pancreatic or peripancreatic lesions underwent EUS-guided FNA with both 22- and 25-gauge Wilson-Cook Echotip needles. All procedures were performed with an Olympus linear echoendoscope by the same endoscopist to eliminate operator-dependent variability. Needle order was selected randomly, and two passes were made with each needle, consisting of ten uniform to-and-fro movements on each pass with 10-ml syringe suction. The specimens were immediately stained and independently reviewed by two cytopathologists, who were blinded to the needle used. Cellularity was graded as 0 to 6, with 6 being most cellular. RESULTS No statistically significant difference in cellularity was detected between the two needle size groups by cytologist 1 (mean difference, 0.04; 95% confidence interval [CI], -1.22 to 1.30; p = 0.94) or by cytologist 2 (mean difference, 0.2; 95% CI, -1.23 to 1.65; p = 0.76). When the data from both cytologists were combined, no significant difference in cellularity was detected between the two needle sizes (mean difference, 0.125; 95% CI, -1.22 to 1.47; p = 0.84). No significant difference in cellularity was detected between cytologists 1 and 2 (mean difference, 0.17; 95% CI, -0.15 to 0.48; p = 0.27). When the order in which needles were used was compared, no significant difference in cellularity was detected (p = 0.75). Three mechanical failures occurred with 25-gauge needles, but none occurred with 22-gauge needles. The visibility of the needles on EUS did not differ. Cytologic diagnoses were achieved in all cases: seven pancreatic adenocarcinomas, one pancreatic giant cell carcinoma, one pancreatic neuroendocrine tumor, one metastatic non-small cell carcinoma, one metastatic colon carcinoma, and one pancreatitis. There were no procedure-related complications. CONCLUSIONS Both FNA needles provided accurate diagnoses in all patients. There was no significant difference between the 22- and 25-gauge needle groups in the independent interpretation of two cytopathologists with respect to cellular yield and ability to render a diagnosis.
