Background and aims : Endoscopic ultrasound fine-needleaspiration/biopsy (EUS-FNA/FNB) is highly accurate, but dis-crepancies between cytological and surgical diagnoses are stillobserved. We aimed to determine its accuracy and monitor qualityindicators in our facilities. Patients and methods : We performed a retrospective review ofall cases of pancreatic solid lesions evaluated by EUS-FNA/FNB,between July 2015 and June 2018, in two centers. Cytologicaland surgical findings were categorized into five groups: benign,malignant, suspect of malignancy, undetermined and insufficientfor diagnosis. Final diagnosis was based on surgical diagnosis and,in patients who did not undergo surgery, on clinical outcome after6 months follow-up. Results : Altogether, 142 patients were included. FNA was thepreferred tissue acquisition method (88%), with a predilection forthe FNA 22G needle (57%). Cytology was insufficient for diagnosisin 2 cases, therefore a full diagnostic sample was available in 98.6%of the patients (>90%, ESGE target). Fifty-five (38.7%) patientsunderwent surgery. In term of cancer diagnosis, comparison withfinal surgical pathology (n=55) revealed 89% true positives, 5.5%true negatives, 3.6% false positives and 1.8% false negatives. Whencombining surgical diagnosis and clinical outcomes together, EUS-guided sampling sensitivity was 97.4% (92.5-99.5), specificity was92.3% (74.9-99.1), positive predictive value was 98.2% (93.6-99.5),negative predictive value was 88.9% (72.3-96.1) and accuracy was96.4% (91.9-98.8). Post-procedural acute pancreatitis was reportedin 2 patients (1.4%). Conclusions : These results reveal a performance for diagnostictissue sampling well above the ESGE proposed target standard.Also, the uncommon high specificity illustrates the determiningrole of the pathologist’s final interpretation and diagnosis.

Abstract Background and aims This study aimed to evaluate the performance of Macroscopic On-site Evaluation (MOSE) using a novel endoscopic ultrasound (EUS) fine needle biopsy (FNB) needle (22-G Franseen-tip needle, Acquire, Boston Scientific Incorporated, Boston, Massachusetts, United States), and without using Rapid On-Site Evaluation (ROSE). Method Between May 2016 and August 2016, all consecutive patients referred to our center for EUS tissue acquisition (TA) for solid lesions underwent EUS-FNB with the 22-G Franseen-tip needle unless contra-indicated. The operator performed MOSE. If no macroscopic core was visualized, a second pass was performed. The final diagnosis was defined as unequivocal histology from EUS-TA with compatible 18 months follow-up, surgical resection, or both. We retrospectively analyzed the performance of MOSE. Results A total of 46 consecutive patients was included, and 54 solid lesions were biopsied. The endosonographer visualized core tissue in 93 % (50/54) of targets with a single pass, of which the pathologist confirmed histologic core fragments in 94 % (47/50). Four lesions required two passes, and the overall correlation between MOSE and histologic core fragments was 94 % (48/51). Diagnostic adequacy was 98 % (53/54) with one biliary target biopsied without significant material. The overall diagnostic accuracy was 94 %. Sensitivity, specificity, positive predictive value, and negative predictive value for malignancy were 92 %, 100 %, 100 %, and 81 %, respectively. No adverse events were reported. Conclusion Our study demonstrated that MOSE using the 22-G Franseen-tip needle could limit needle passes by accurately estimating histologic core fragments. It also demonstrated that high diagnostic adequacy and accuracy of > 90 % could be achieved without ROSE.

Background and Aim. A wet suction technique (“wet” technique) has been developed to improve the quality of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) for sampling various solid lesions. However, no studies have reported on the wet technique for EUS-FNA for gastrointestinal (GI) subepithelial lesions (SELs). We conducted a pilot randomized crossover trial to explore whether the wet technique could be useful with regard to tissue adequacy of upper GI-SELs (UGI-SELs) compared to the conventional EUS-FNA technique (“dry” technique). Methods. Twenty-six patients with UGI-SELs indicated for EUS-FNA were randomly assigned to the dry-first arm using the dry technique for the first two passes or the wet-first arm using the wet technique for the first two passes using a cross-over design with a ratio of 1 : 1. The primary endpoint was the cellularity score of the EUS-FNA specimens rated on a 4-point scale (0-3). The secondary endpoints were the factors influencing cellularity in each suction technique. Results. The mean cellularity score was 1.65 ± 1.20 for the wet technique and 2.00 ± 0.98 for the dry technique ( p = 0.068 ). Logistic regression analysis showed that higher cellularity may be related to the final diagnosis of gastrointestinal stromal tumors in the dry technique and the SEL location in the upper stomach in the wet technique. Conclusion. The wet EUS-FNA technique failed to show a potential for improved cellularity of specimens compared to the dry technique for UGI-SELs.

Abstract Introduction: Space occupying lesions (SOLs) of the pancreas are commonly encountered in day to day practice either as an incidental finding or during evaluation of symptomatic patients. The aim of the present study was to compare the final diagnosis at follow-up with diagnosis made at computed tomography (CT)/magnetic resonance imaging (MRI) and endoscopic ultrasound (EUS). Materials and Methods: Retrospective analysis of EUS data of 131 patients referred for tissue diagnosis of SOL in pancreas was done. The lesions were classified as malignant, benign, and nonneoplastic by both CT/MRI and endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) in conjunction with clinical presentation, biochemical parameters, and tumor markers. Follow-up cases with a final diagnosis alone were included for the comparative analysis. Statistical Analysis: Chi-square test, sensitivity, specificity, positive predictive value (PPV), and negative predictive values (NPV) for CT/MRI and EUS-FNA were computed against the follow-up data. Results: Of the 131, there were 78 males (59.5%). The median age of presentation was 48 years (range: 11–82 years. Follow-up information on the final diagnosis was available for 54 patients. Confirmed diagnosis at follow-up was malignant lesion in 18, benign in 13 and 23 with a nonneoplastic lesion. When EUS-FNA outcome was compared with the definitive diagnosis of the 54 patients, it had a higher sensitivity for malignant (66.7% vs. 61.1%) and nonneoplastic lesions (78.3% vs. 73.9%) and was similar to CT/MRI for benign lesions (76.9% for both). EUS-FNA had a higher specificity (87.8% vs. 80.5%) with a good PPV for benign lesions (66.7% vs. 55.6%). CT/MRI was less accurate than EUS-FNA in predicting benign (79.6% vs. 85.2%) and nonneoplastic lesions (79.6% vs. 81.5%) compared to malignant lesions wherein it was similar at 81.5%. The high NPV with a lower PPV for both EUS/FNA and CT/MRI suggests that follow-up definitive diagnosis was superior to both –. Conclusions: Endoscopic ultrasound-guided fine-needle aspiration had a higher specificity, but low sensitivity for the both neoplastic and nonneoplastic lesion of the pancreas compared to the world literature. The overall EUS-FNA yield was low when compared to the follow-up definitive diagnosis.

Abstract Background The prevalence of malignancy in patients with small solid pancreatic lesions is low; however, early diagnosis is crucial for successful treatment of these cases. Therefore, a method to reliably distinguish between benign and malignant small solid pancreatic lesions would be highly desirable. We investigated the role of endoscopic ultrasound (EUS) elastography in this setting. Methods Patients with solid pancreatic lesions ≤ 15 mm in size and a definite diagnosis were included. Lesion stiffness relative to the surrounding pancreatic parenchyma, as qualitatively assessed and documented at the time of EUS elastography, was retrospectively compared with the final diagnosis obtained by fine-needle aspiration/biopsy or surgical resection. Results 218 patients were analyzed. The average size of the lesions was 11 ± 3 mm; 23 % were ductal adenocarcinoma, 52 % neuroendocrine tumors, 8 % metastases, and 17 % other entities; 66 % of the lesions were benign. On elastography, 50 % of lesions were stiffer than the surrounding pancreatic parenchyma (stiff lesions) and 50 % were less stiff or of similar stiffness (soft lesions). High stiffness of the lesion had a sensitivity of 84 % (95 % confidence interval 73 % – 91 %), specificity of 67 % (58 % – 74 %), positive predictive value (PPV) of 56 % (50 % – 62 %), and negative predictive value (NPV) of 89 % (83 % – 93 %) for the diagnosis of malignancy. For the diagnosis of pancreatic ductal adenocarcinoma, the sensitivity, specificity, PPV, and NPV were 96 % (87 % – 100 %), 64 % (56 % – 71 %), 45 % (40 % – 50 %), and 98 % (93 % – 100 %), respectively. Conclusions In patients with small solid pancreatic lesions, EUS elastography can rule out malignancy with a high level of certainty if the lesion appears soft. A stiff lesion can be either benign or malignant.

<b><i>Objective:</i></b> This study aims to determine the diagnostic utility of the International Academy of Cytology (IAC) Yokohama System for reporting breast cytopathology in lesions of the male breast. <b><i>Study Design:</i></b> Fine-needle aspiration biopsy (FNAB) reports between 2015 and 2019 were retrospectively recategorized according to the 5-tiered IAC Yokohama Reporting System. Our database yielded a total of 1,532 FNAB reports from breast lesions, obtained from 1,350 male patients. The risk of malignancy (ROM) and diagnostic performance of FNAB were determined using follow-up histopathological diagnosis and/or clinical follow-up, where available, for each category. <b><i>Results:</i></b> The category distribution were as follows: inadequate, 40%; benign, 57%; atypical, 0.6%; suspicious for malignancy, 0.7%; and malignant, 1.6%. The ROM in each category was nondiagnostic, 11%; benign, 3%; atypical, 28%; suspicious for malignancy, 56%; and malignant, 100%. The sensitivity, specificity, positive predictive value, and negative predictive value were recorded as 63, 100, 100, and 84.6% respectively, when only malignant cases were considered as positive tests. <b><i>Conclusion:</i></b> This study validates the IAC Yokohama System for reporting male breast cytopathology. In accordance with the aim of the Yokohama System to establish best practice guidelines for reporting breast cytopathology, this comprehensive scheme facilitates comparisons between local and international institutions. The ROM acts as an internal audit for quality assurance within one’s own laboratory and provides guidance for clinical management. It highlights inefficiencies such as high inadequacy rates for category 1 and also features strengths with impressive specificity for categories 4 and 5.

AbstractCystic pancreatic lesions (CPLs) are frequently casual findings in radiological examinations performed for other reasons in patients with unrelated symptoms. As they require different management according to their histological nature, differential diagnosis is essential. Radiologist plays a key role in the diagnosis and management of these lesions as imaging is able to correctly characterize most of them and thus address to a correct management. The first step for a correct characterization is to look for a communication between the CPLs and the main pancreatic duct, and then, it is essential to evaluate the morphology of the lesions. Age, sex and a history of previous pancreatic pathologies are important information to be used in the differential diagnosis. As some CPLs with different pathologic backgrounds can show the same morphological findings, differential diagnosis can be difficult, and thus, the final diagnosis can require other techniques, such as endoscopic ultrasound, endoscopic ultrasound-fine needle aspiration and endoscopic ultrasound-through the needle biopsy, and multidisciplinary management is important for a correct management.

Background: Fine-needle aspiration (FNA) plays a fundamental role in determining the appropriate management for patients presenting with thyroid nodules. Aims: The aims of this study are to evaluate thyroid FNA test performance parameters through a cytohistological correlation. Materials and Methods: A retrospective analysis of all thyroid FNAs received over a period of 18 months was carried out. The findings were compared to their subsequent definite diagnoses on surgical specimens as well as to their follow-up repeat FNA results. A total of 499 thyroid FNAs were collected and reviewed against The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC). The percentage of each diagnostic category was calculated, and the implied risk of malignancy was determined by comparing the cytology results to their definite diagnoses obtained on the resection specimens. Analytical procedures were performed using Microsoft Excel. Results: Out of 499 thyroid FNAs, a benign interpretation was found in 273 patients (54.7%), atypia of undetermined significance in 81 (16.2%), follicular neoplasm in 20 (4%), suspicious for malignancy in 36 (7.2%), malignant in 32 (6.4%) and were nondiagnostic in 57 patients (11.4%). Only 101 patients (20.2%) underwent surgical resection and 47 (9.4%) underwent a follow-up FNA. After cytohistological correlation, FNA test performance, calculated by excluding the inadequate and undetermined categories revealed test sensitivity, specificity, and diagnostic accuracy of 95.6%, 54.8%, and 78.9%, respectively. The positive predictive value was 75.4%, and the negative predictive value was 89.5%. Conclusions: Our results are comparable to those previously published figures. The rate of atypia of undetermined significance/follicular lesion of undetermined significance is higher than what is currently recommended in TBSRTC.

<b><i>Objective:</i></b> The Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) is a recently published evidence-based categorization system for salivary gland fine-needle aspiration (FNA). We applied MSRSGC to Japanese cases and evaluated its utility. <b><i>Study Design:</i></b> A total of 480 FNA cases were reviewed. We recategorized each case into one of the MSRSGC categories. The risk of neoplasm (RON) and the risk of malignancy (ROM) for each diagnostic category in MSRSGC, and the sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) for malignancy and for neoplasms were calculated for cases with histological follow-up. In addition, the overall ROM (O-ROM) was calculated for all FNA cases. <b><i>Results:</i></b> RON, ROM, and O-ROM rates were as follows – non-diagnostic: 51.3, 5.1, and 1.0%; non-neoplastic: 0, 0, and 0%; atypia of undetermined significance: 83.9, 12.9, and 7.3%; neoplasm, benign: 100, 0, and 0%; salivary gland neoplasm of uncertain malignant potential: 100, 32.1, and 23.7%; suspicious for malignancy: 100, 85.7, and 60%; and malignant: 100, 100, 81.8%. The sensitivity, specificity, and accuracy with (without) indeterminate cases for malignancy were 65 (100), 99 (99), 92% (99%) and PPV and NPV were 96 and 100%, respectively, and those for neoplasms were 84 (100), 100 (100), 85% (100%), and PPV and NPV were 100 and 100%, respectively. <b><i>Conclusions:</i></b> The MSRSGC is useful for stratification of ROM and for promoting the performance of salivary gland FNA. The MSRSGC could be easily introduced in Japan and may improve the Japanese salivary gland FNA status.
