Abstract
PURPOSE Pregnancy-associated plasma protein A (PAPPA) is a metalloproteinase initially described for its role during pregnancy. PAPPA regulates IGF ligands 1 (IGF1) bioavailability through the degradation of IGF-binding protein 4 (IGFBP4). After the cleavage of IGFBP4, free IGF1 is able to bind IGF1 receptors (IGF1R) triggering the downstream signaling. Recently, PAPPA expression has been linked with development of several cancers. No data have been published on thyroid cancer, yet. METHODS We evaluated PAPPA, insulin-like growth factor (IGF1), IGF1 receptors (IGF1R) and IGF-binding protein 4 (IGFBP4) mRNA expression levels in a "Surgical series" of 94 thyroid nodules (64 cancers, 16 follicular adenomas and 14 hyperplastic nodules) and in a "Cytological series" of 80 nodules from 74 patients underwent to fine-needle aspiration cytology (FNAC). In tissues, PAPPA was also evaluated by western blot. RESULTS We found that PAPPA expression was increased in thyroid cancer specimen at mRNA and protein levels and that, adenomas and hyperplastic nodules had an expression similar to normal tissues. When applied on thyroid cytologies, PAPPA expression was able to discriminate benign from malignant nodules contributing to pre-surgical classification of the nodules. We calculated a cut-off with a good specificity (91%) which reached 100% when combined with molecular biology. CONCLUSION These results show that PAPPA could represent a promising diagnostic marker for differentiated thyroid cancer.

Abstract
BACKGROUND The 2015 American Thyroid Association (ATA2015) and the American College of Radiology Thyroid Imaging and Reporting Data System (ACR TI-RADS) are two widely used thyroid sonographic systems. OBJECTIVES To compare the two systems for accuracy of cancer risk prediction. METHODS Preoperative ultrasound images from 265 patients who underwent thyroidectomy at our hospital from January 2012 to March 2019 were retrospectively categorized by the ACR TI-RADS and ATA2015 systems. Diagnostic performances were compared. RESULTS Of 238 nodules assessed, 115 were malignant. Malignancy risks for the five ACR TI-RADS categories were 0%, 7.5%, 11.4%, 59.6%, and 90.0%. Malignancy risks for the five ATA2015 categories were 0%, 6.8%, 17.0%, 55.5%, and 92.1%. The proportion of total nodules biopsied was higher with the ATA2015 system than the ACR TI-RADS system: 88.7% vs. 66.3%. Proportions of malignant nodules and benign nodules biopsied were higher with ATA2015 than with ACR TI-RADS: 93.3% vs. 87.8% and 84.4% vs. 46.3%, respectively. Specificity and sensitivity rates were 53.6% and 84.3%, respectively, for ACR TI-RADS, and 15.5% and 93.3%, respectively, for ATA2015. The two systems showed similarly accurate diagnostic performance (AUC > 0.88). False negative rates for ACR TI-RADS and ATA2015 were 15.6% and 6.6%, respectively. Rates of missed aggressive cancer were similar for the two systems: 3.4% and 3.7%, respectively. CONCLUSIONS ACR TI-RADS was superior to ATA2015 in specificity and avoiding unnecessary biopsies. ATA2015 yielded better sensitivity and a lower false negative rate. Identification of aggressive cancers was identical in the two systems.

Abstract
Importance Thyroid cancer, predominantly papillary thyroid carcinoma (PTC), is common, but an estimated 30% of ultrasonography-guided fine-needle aspiration (FNA) biopsies of thyroid nodules are indeterminate. BRAF variation, associated with poor clinicopathological characteristics, is a useful molecular marker for diagnostics. Objective To develop a sensitive molecular assay for BRAF V600E detection in remaining tissue of thyroid FNA biopsies to identify patients with cancer carrying a BRAF variation. Design, Setting, and Participants This diagnostic study used tumor tissue from surgical formalin-fixed, paraffin-embedded (FFPE) specimens and residual tissue from thyroid FNA biopsies for genomic DNA extraction. FFPE specimens served as the validation set, and residual tissue from FNA biopsies served as the test set. A molecular assay was developed for accurate detection of BRAF V600E variation using locked nucleic acid (LNA) probe-based droplet digital polymerase chain reaction (dPCR), and the assay was validated by BRAF V600E immunohistochemical staining (IHC). The study was conducted between February 2019 and May 2021. Results A total of 271 specimens, including 77 FFPE specimens (with a follow-up of 48 matched surgical specimens) and 146 residual FNA samples, were collected from 223 patients (mean [SD] age, 53.8 [15.3] years; 174 [78.0%] women; 49 [22.0%] men). The molecular assay by dPCR was first established to specifically and accurately detect and quantify wild-type BRAF and variant BRAF in DNA from human follicular thyroid carcinoma-derived FTC-133 and papillary thyroid carcinoma-derived BCPAP cells. The linearity of quantification of BRAF V600E was calculated (y = 0.7339x; R2 = 0.9996) with sensitivity at 0.02 copies/μL and reproducibility in detecting variant DNA at various dilutions(coefficient of variance in 0.3% DNA, 9.63%; coefficient of variance in 1.0% DNA, 7.41%). In validation testing, the dPCR assay and IHC staining exhibited 100% specificity in concordantly identifying BRAF V600E in PTCs (κ = 0.873; P < .001) and sensitivity of 32.0% (95% CI, 19.1% to 44.9%) in dPCR and 26.0% (95% CI, 13.1% to 38.9%) in IHC staining, with an improvement by 23.08% in dPCR compared with the IHC staining. The dPCR assay further detected BRAF V600E in 39 of 146 residual FNA specimens (26.7%). At short-term follow-up, 48 patients, including 14 of 39 patients with BRAF variation and 34 of 107 patients without BRAF variation on residual FNA specimens, underwent resection. The dPCR assay of BRAF status in the matched surgical specimens showed BRAF V600E variations in 12 patients and wild-type BRAF in 36 patients, with a high agreement to that in residual tissue of FNA specimens (κ = 0.789; P < .001). Among 14 patients with BRAF variations on residual FNA, 13 were diagnosed with PTC and 1 was diagnosed with anaplastic thyroid cancer at the thyroidectomy. Conclusions and Relevance This diagnostic study developed a sensitive molecular assay for detection and quantification of BRAF V600E variation in residual tissue from thyroid FNA biopsies to identify patients with cancer harboring BRAF V600E in a cost-effective manner, highlighting the clinical value of molecular assay of the remaining FNA tissue in the management of thyroid nodules.

Abstract
BACKGROUND The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) predicts the risk of malignancy for the different categories of the ultrasound-guided fine-needle aspiration biopsy (FNAB). The objective of this study is to investigate the efficiencies of the v-raf murine sarcoma viral oncogene homolog B1 (BRAF) V600E mutation test and the TBSRTC categories in distinguishing between benign and malignant thyroid nodules. METHODS In this study, 362 ultrasound-guided fine-needle aspiration (FNA) samples from 344 patients aged from 17 to 76 years old were retrospectively reviewed. The patients were classified into six groups (I-VI) according to the TBSRTC system. The amplification refractory mutation system-polymerase chain reaction (ARMS-PCR) was used to evaluate the BRAF V600E mutation level in total 362 samples. Among of the 344 patients, 128 patients (131 thyroid nodules) who underwent surgeries were followed by histopathological examination. The predictive values of the BRAF V600E mutation test and TBSRTC categories were evaluated in these 131 thyroid nodules. RESULTS The median ages of the patients in the TBSRTC IV-VI group were smaller than those in the TBSRTC I-III groups. The proportion of nodules over 1 cm was larger than it in the TBSRTC IV group compared to the other groups. Significant differences in BRAF V600E mutation were observed (P < .001) among these six groups. The sensitivity (89.57%) for the detection of malignant thyroid nodules, negative predictive value (NPV; 45.45%) for the detection of benign nodules, and accuracy (86.26%) for distinguishing between benign and malignant thyroid nodules increased by combining the BRAF V600E mutation test and TBSRTC system when compared with the BRAF V600E mutation test and TBSRTC system respectively. The BRAF V600E mutation test alone demonstrated the increased positive predictive value (PPV; 98.91%) and specificity (93.75%) for the detection of malignant thyroid nodules compared to the TBSRTC method (alone or in combination with the BRAF V600E method). CONCLUSION In summary, significant differences in age, nodule diameter, and BRAF V600E mutation were noted among the six categories of the TBSRTC system. The combination of the BRAF V600E mutation test and TBSRTC system demonstrated increases in the NPV, sensitivity, and accuracy, while the BRAF V600E method proved superiority to the TBSRTC system with regard to the PPV and specificity.

Abstract
OBJECTIVE We compared demographic and clinic-pathological variables related to the number of surgeries for thyroid conditions or for cancer, morbidity, and fine needle aspiration (FNA) practices among Covid19 pandemic phases I, II, III and the same seasonal periods in 2019. METHODS The prospective database of the Division of Thyroid Surgery, China-Japan Union Hospital of Jilin University, Changchun, China was used for this study. Covid19 emergency levels were stratified according to the World Health Organization: phase I (January 25-February 25, 2020), phase II (February 26-March 19), phase III (March 20-April 20). RESULTS There were fewer outpatient FNAs and surgeries in 2020 than in 2019. There were no thyroid surgeries during phase I. There were also fewer surgeries for cancer with a significant reduction of advanced stage cancer treatments, mainly stage T1b N1a in phase II and T3bN1b in phase III. Operative times and postoperative stays were significantly shorter during the pandemic compared to our institutional baseline. In phase III, vocal cord paralysis (VCP) increased to 4.3% of our baseline numbers (P = 0.001). There were no cases of Covid19-related complications during the perioperative period. No patients required re-admission to the hospital. CONCLUSION The Covid19 outbreak reduced thyroid surgery patient volumes. The decrease of Covid19 emergency plans contributed to unexpected outcomes (reduction of early stage cancer treatment, decreased operative times and hospital stays, increased VCP rate).

Abstract
PURPOSE Nowadays, the clinical management of thyroid nodules needs to be multi-disciplinary. In particular, the crosstalk between endocrinologists and cytopathologists is key. When FNAs are properly requested by endocrinologists for nodules characterised by relevant clinical and ultrasound features, cytopathologists play a pivotal role in the diagnostic work-up. Conversely, improper FNA requests can lead to questionable diagnostic efficiency. Recently, recommendations to delay all non-urgent diagnostic procedures, such as thyroid FNAs, to contain the spread of COVID-19 infection, have made the interplay between endocrinologists and cytopathologists even more essential. The objective of this study was to assess the impact of COVID-19 pandemic on our practice by evaluating the total number of FNAs performed and the distribution of the Bethesda Categories before, during, and after the lockdown. METHODS We analysed the FNA trends before (1st January 2019 to March 13th 2020), during (March 14th to May 15th), and after (May 16th to July 7th) the lockdown. RESULTS Although the total number of weekly FNAs dropped from 62.1 to 23.1, our referring endocrinologists managed to prioritise patients with high-risk nodules. In fact, in the post-lockdown, the weekly proportion of benign diagnoses dropped on average by 12% and that of high-risk diagnoses increased by 6%. CONCLUSIONS The lesson we have learned so far from this pandemic is that by applying safety protocols to avoid contagion and by increasing the threshold for FNA requests for thyroid nodules, we can continue to guarantee our services to high-risk patients even in times of a health crisis.

Abstract
OBJECTIVES A trial-based comparison of the use of resources, costs and health utility outcomes of fine-needle aspiration cytology (FNAC), and watchful observation for incidental small (< 2 cm) thyroid nodules was performed using data from the randomized controlled trial (RCT). METHODS Using data from 314 patients, healthcare-related use of resources, costs, health utility, and quality-adjusted life years (QALYs) were estimated at 12 months after first presentation of incidental thyroid nodule(s) on an intention-to-treat basis with adjustment for covariates. Uncertainty about the incremental cost-effectiveness ratio for FNAC versus watchful management at 12 months of follow-up was incorporated using bootstrapping. Multiple imputation methods were used to deal with missing data. RESULTS FNAC management was associated with greater use of healthcare resources and mean direct healthcare costs per patient (US$542.47 vs US$411.55). Lower mean 12-month QALYs per patient in FNAC was observed in comparison to watchful observation (0.752 versus 0.758). The probability that FNAC management was cost-effective compared with watchful management at a willingness-to-pay threshold of US50,000 per QALY gained was 26.5%. CONCLUSION Based on 12-month data from RCT, watchful observation appeared cost-saving compared to FNAC in patients with incidental thyroid nodules that have a low-suspicion sonographic pattern and measure between 1.0 and 2.0 cm from healthcare provider perspective.

Abstract
OBJECTIVE To compare diagnostic performance and malignancy risk stratification among guidelines set forth by the American Thyroid Association (ATA) in 2015, the American Association of Clinical Endocrinologists (AACE), the American College of Endocrinology (ACE) and the Association Medici Endocrinologi (AME) in 2016, and the American College of Radiology (ACR) in 2017. METHODS The retrospective study was approved by the hospital ethics committee, and the informed consent requirement was waived. From October 2015 to March 2016, a total of 230 patients with 230 consecutive thyroid nodules were enrolled in this study. Each nodule was classified by one junior and one senior radiologist separately according to ACR TI-RADS, AACE/ACE/AME and ATA guidelines. The malignancy diagnostic performance and the number of FNA recommendations were pairwise compared among three guidelines using chi-square tests. RESULTS Of the 230 thyroid nodules, 137 were malignant, and 93 were benign. However, 19.6% of the nodules (45 of 230) did not match any pattern using the ATA guidelines but with a high risk of malignancy (68.9%). The ACR TI-RADS derived the highest diagnostic performance, from both junior radiologist (AUC 0.815) and senior radiologist (AUC 0.864). The ACR guidelines also showed the greatest level of sensitivity (junior: 86.1%, senior: 94.9%), compared with AACE/ACE/AME and ATA guidelines. The number of thyroid nodules recommended to fine-needle aspiration (FNA) was the lowest (37.8%, 40.4%) by ACR TI-RADS, and meanwhile, the malignant detection rate within these nodules was highest (64.4%, 68.8%). CONCLUSIONS The ACR guidelines present a higher level of diagnostic indicators and may offer a meaningful reduction in FNA recommendations with a higher malignancy detection rate.

Abstract
OBJECTIVE To assess the accuracy of preoperative ultrasound examination for predicting lymph-node (LN) status in patients with vulvar cancer. METHODS This was a single-institution retrospective observational study of all women with a histological diagnosis of vulvar cancer triaged to inguinal surgery within 30 days following ultrasound evaluation between December 2010 and January 2016. For each groin examined, 15 morphological and dimensional sonographic parameters associated with suspicion for LN involvement were examined. A morphometric ultrasound pattern (MUP) was expressed for each groin, classifying the inguinal LN status into five groups (normal; reactive-but-negative; minimally suspicious/probably negative; moderately suspicious; and highly suspicious/positive) according to subjective judgment, followed by stratification as positive or negative for metastasis according to morphometric binomial assessment (MBA). In cases of positive MBA, fine-needle aspiration cytology was performed. Combining the information obtained from MUP and cytologic results, a binomial final overall assessment (FOA) was assigned for each groin. The final histology was considered as the reference standard. Comparison was performed between patients with negative and those with positive LNs on histology, and receiver-operating-characteristics curves were generated for statistically significant variables on univariate analysis, to evaluate their diagnostic ability to predict negative LN status. RESULTS Of 144 patients included in the analysis, 87 had negative inguinal LNs and 57 had positive LNs on histology. A total of 256 groins were analyzed, of which 171 were negative and 85 showed at least one metastatic LN on histology. The following parameters showed the greatest accuracy, with the best balance between specificity and sensitivity, in predicting negative LN status: cortical (C) thickness of the dominant LN (cut-off, 2.5 mm; sensitivity, 90.0%; specificity, 77.9%); short-axis (S) length of the dominant LN (cut-off, 8.4 mm; sensitivity, 63.9%; specificity, 90.6%); C/medulla (M) thickness ratio of the dominant LN (cut-off, 1.2 mm; sensitivity, 70.4%; specificity, 91.5%), the combination of S length and C/M thickness ratio (sensitivity, 88.9%; specificity, 82.4%); and the FOA analysis (sensitivity, 85.9%; specificity, 84.2%). CONCLUSIONS Preoperative ultrasound assessment, with or without the addition of cytology, has a high accuracy in assessing inguinal LN status in patients with vulvar cancer. In particular, the combination of two ultrasound parameters (S length and C/M thickness ratio) provided the greatest accuracy in discriminating between negative and positive LNs.

Abstract
OBJECTIVES To evaluate the impact of systematic radiological review by breast specialist radiologist of malignant breast lesion imaging on the therapeutic management of patients. MATERIALS AND METHODS Data collection was performed for patients with histopathologically proved breast cancer or suspicious breast lesion on imaging realized out of our institution. Patients underwent systematic mammary and axillary ultrasound, imaging review and if necessary complementary mammographic images. We analyzed the number of additional breast biopsies and axillary lymph node fine needle aspiration (FNA) with their histopathological results. We assessed their impact by comparing the final surgical treatment to the one planned before review. RESULTS Two hundred and seventeen patients were included, with a total of 230 BIRADS 0, 4, 5 or 6 breast lesions. Seventy-six additional breast core biopsies were realized, leading to diagnose 43 additional BIRADS 6 lesions (24 infiltrative carcinomas, 9 DCIS and 10 atypical lesions) in 30 patients (13.82%). Thirty-five additional lymph node FNA were realized with 12 metastatic nodes and 3 false negative samples. Imaging review lead to change surgical treatment in 59 patients (27.19%, P<0.01) with modification in breast surgery in 37 patients, axillary surgery in 8 patients and both sites surgery in 12 patients. CONCLUSION This study shows an impact of systematic radiological review by breast specialist radiologist in therapeutic management of patients treated for malignant breast lesion.

Abstract
BACKGROUND The aim of this study was to compare the diagnostic utility of fine needle aspiration cytology (FNAC) in breast lesion with gold standard of histopathological diagnosis. METHODS This descriptive cross-sectional study was conducted in Pathology department of Bannu Medical College in collaboration with Surgery Department of Khalifa Gul Nawaz Teaching Hospital Bannu as well as other private surgical hospitals of the territory. A total of 88 FNAC of palpable breast lesions were performed and compared with their corresponding histopathological reports. Patients age, location of lesion in breast, and other necessary findings were recorded on predesigned proforma, FNAC performed by using 10 ml syringes. Slides prepared and processed for cytological staining and reported by cytopathologist. Corresponding biopsies were processed for histopathological examination and diagnosis. All female patients of any age with breast lesions were included, and those breast lesions for which no histopathological report was available were excluded. Statistical Package for Social Sciences (SPSS) version 20 was used for calculation of frequencies with percentages and mean with standard deviation. Also, specificity, sensitivity, diagnostic accuracy, positive predictive value and negative predictive value were calculated by using formulas. RESULTS In this study the mean age was 34.44±21.57 years and age range was from 16 to 80 years. The most common age group was 26-35 years followed by 36-45 years. In this study sensitivity was (83.33%), specificity was (100 %), positive predictive value was (100 %), negative predictive value was (99.27%) and diagnostic accuracy was 99.30%. CONCLUSIONS FNAC breast is an easily approachable, less invasive, cheap, rapid and almost accurate diagnostic tool in the diagnosis of palpable as well as non palpable breast lesions.

Abstract
BACKGROUND AND OBJECTIVE Digital scanners are being increasingly adopt-ed in anatomical pathology, but there is still a lack of a standardized whole slide image (WSI) format. This translates into the need for interoperability and knowledge representation for shareable and computable clinical information. This work describes a robust solution, called Visilab Viewer, able to interact and work with any WSI based on the DICOM standard. METHODS Visilab Viewer is a web platform developed and integrated alongside a proposed web architecture following the DICOM definition. To prepare the information of the pyramid structure proposed in DICOM, a specific module was defined. The same structure is used by a second module that aggregates on the cache browser the adjacent tiles or frames of the current user's viewport with the aim of achieving fast and fluid navigation over the tissue slide. This solution was tested and compared with three different web viewers, publicly available, with 10 WSIs. RESULTS A quantitative assessment was performed based on the average load time per frame together with the number of fully loaded frames. Kruskal-Wallis and Dunn tests were used to compare each web viewer latency results and finally to rank them. Additionally, a qualitative evaluation was done by 6 pathologists based on speed and quality for zooming, panning and usability. The proposed viewer obtained the best performance in both assessments. The entire architecture proposed was tested in the 2nd worldwide DICOM Connectathon, obtaining successful results with all participant scanner vendors. CONCLUSIONS The online tool allows users to navigate and obtain a correct visualization of the samples avoiding any restriction of format and localization. The two strategical modules allow to reduce time in displaying the slide and therefore, offer high fluidity and usability. The web platform manages not only the visualization with the developed web viewer but also includes the insertion, manipulation and generation of new DICOM elements. Visilab Viewer can successfully exchange DICOM data. Connectathons are the ultimate interoperability tests and are therefore required to guarantee that solutions as Visilab Viewer and its architecture can successfully exchange data following the DICOM standard.

Abstract
A re-named diagnosis of noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) likely impacts the prevalence of thyroid cancer and risk of malignancy in populations based on the established Bethesda System of Reporting Thyroid Cytopathology (TBSRTC). This study was done to investigate the prevalence and cytological distribution of NIFTP. PRISMA guided systematic review was done from a database search of Pubmed, EMBASE, and Medline using the search terms "non-invasive follicular thyroid neoplasm with papillary-like nuclear features", "non-invasive follicular variant of papillary carcinoma", "niftp", and "Bethesda" until November 2018. Original articles with surgically proven diagnoses of NIFTP using strict NIFTP criteria were included. Twenty-nine studies with 1563 cases of NIFTP were included. The pooled prevalence of NIFTP in cases which would be classified previously as the follicular variant of papillary thyroid cancer (FVPTC) and papillary thyroid cancer (PTC) were 43.5% (95% CI 33.5-54.0%) and 4.4% (95% CI 2.0-9.0%) respectively. The pooled TBSRTC distribution of cases diagnosed as NIFTP was: from the non-diagnostic category 3.6% (95% CI 2.4-5.3%), benign 10.0% (95% CI 7.2-13.6%), AUS/FLUS 34.2% (95% CI 28.2-40.8%), FN/SFN 22.7% (95% CI 17.2-29.4%), suspicious for malignancy 22.4% (95% CI 17.7-27.9%), and malignant 7.5% (95% CI 4.2-12.9%). While a significant reduction in FVPTC prevalence is anticipated, a modest reduction of PTC prevalence is also expected with adoption of the NIFTP terminology that would be distributed mainly among lesions classified as indeterminate thyroid nodules. Further studies are needed to identify unique clinical characteristics of these lesions preoperatively.

Abstract
PURPOSE The purpose of this study was to compare patients' pain and satisfaction of fine needle aspiration (FNA) and core needle biopsy (CNB) for a thyroid nodule. METHODS We consecutively enrolled patients with thyroid nodules who underwent ultrasound-guided FNA or CNB in our institution. The patients answered a questionnaire about pain scores during the procedure, immediately after the procedure and 20 min after the procedure, and any complication after the biopsy. Through a phone interview which was conducted 2 weeks after the procedure, a researcher asked the patients about residual pain and overall subjective satisfaction score about the procedures. Patients were also asked to report any complication or complaint after the procedures on the phone interview. RESULTS The 167 patients who had undergone thyroid FNA (n = 87) or CNB (n = 80) were included. The pain scores were not significantly different between the two groups during the procedure and after the procedure. Overall satisfaction scores after 2 weeks were not different, either. There was no acute or delayed major complication in both groups. CONCLUSIONS Differences regarding patients' pain and satisfaction scores between CNB and FNA were not demonstrated.

Abstract
INTRODUCTION The second edition of The Bethesda System for Reporting Thyroid Cytopathology has incorporated the recent change in nomenclature, noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP), with an anticipated change in the risk of malignancy (ROM). We examined our institutional experience in the incidence of NIFTP and the change in the ROM in The Bethesda System for Reporting Thyroid Cytopathology. MATERIALS AND METHODS A computerized search was performed from January 2013 to August 2017 for all thyroid fine needle aspirations (FNAs), the corresponding surgical resection specimens, and clinical follow-up data. All thyroid specimens reported as follicular variant of papillary thyroid carcinoma were reviewed and reclassified, and all NIFTP diagnoses from April 2016 to August 2017 were identified. The ROM for each category was calculated before and after the change and analyzed for significance. RESULTS A total of 4500 thyroid FNA cases were collected. Of these, 479 cases had surgical resection specimens available and 36 cases had been diagnosed as NIFTP. Of these, 22 had been previously diagnosed as FVPT. Of 27 cases of NIFTP, 14 and 13 were atypia of undetermined significance/follicular lesion of undetermined significance and follicular neoplasm/suspicious for follicular neoplasm, respectively. A reduction in the ROM was observed in these 2 categories (P = 0.03 and P = 0.04, respectively). CONCLUSIONS In our institution, NIFTP has accounted for 13% of all malignant thyroid neoplasms since the change in nomenclature. Although the ROM was decreased in the affected categories, with absolute statistically significant decreases in ROM of 15% and 16.2% for category III and IV, respectively, the overall ROM change was marginal.

Abstract
BACKGROUND Atypia of undetermined significance or follicular lesion of undetermined significance (AUS/FLUS) criterion in thyroid fine-needle aspirates (FNAs) has been a heterogeneous entity with much inter-observer variation. Sub-categorisation of AUS/FLUS has been observed to play an effective role in risk stratification. We aimed to validate AUS/FLUS sub-categorisation in correlation with the spectrum of malignancy. STUDY DESIGN Subjects included patients with AUS/FLUS diagnosed between January 2015 and December 2016. AUS/FLUS cases were sub-categorised into those exhibiting (1) architectural atypia, (2) cytological atypia, (3) architectural and cytological atypia, (4) AUS with Hürthle cells, and (5) AUS not otherwise specified (AUS-NOS). Each sub-category was correlated with their corresponding incidence of malignancy in surgical resections. RESULT The overall incidence of AUS/FLUS in our centre was 13% (132/1,018). On retrospective review of 117 patients with AUS/FLUS, smears with cytological atypia showed a higher incidence of malignancy (78.3%) than those with architectural atypia (75.3%). AUS/FLUS cases with both cytological and architectural atypia had a malignancy rate of 71.4%. CONCLUSION AUS/FLUS cases with cytological atypia had a higher risk of malignancy than those with architectural atypia. The sub-categorisation of AUS/FLUS is diagnostically important for the proper risk stratification of patients.

Abstract
CONTEXT The prevalence of thyroid nodules in the general population is increasingly high, and at least half of those biopsied prove to be benign. Sonographic risk-stratification systems are being proposed as "rule-out" tests that can identify nodules that do not require fine-needle aspiration (FNA) cytology. OBJECTIVE To comparatively assess the performances of five internationally endorsed sonographic classification systems [those of the American Thyroid Association, the American Association of Clinical Endocrinologists, the American College of Radiology (ACR), the European Thyroid Association, and the Korean Society of Thyroid Radiology] in identifying nodules whose FNAs can be safely deferred and to estimate their negative predictive values (NPVs). DESIGN Prospective study of thyroid nodules referred for FNA. SETTING Single academic referral center. PATIENTS Four hundred seventy-seven patients (358 females, 75.2%); mean (SD) age, 55.9 (13.9) years. MAIN OUTCOME MEASURES Number of biopsies classified as unnecessary, false-negative rate (FNR), sensitivity, specificity, predictive values, and diagnostic ORs for each system. RESULTS Application of the systems' FNA criteria would have reduced the number of biopsies performed by 17.1% to 53.4%. The ACR Thyroid Imaging Reporting and Data System (TIRADS) allowed the largest reduction (268 of 502) with the lowest FNR (NPV, 97.8%; 95% CI, 95.2% to 99.2%). Except for the Korean Society of Thyroid Radiology TIRADS, all other systems exhibited significant discriminatory performance but produced significantly smaller reductions in the number of procedures. CONCLUSIONS Internationally endorsed sonographic risk stratification systems vary widely in their ability to reduce the number of unnecessary thyroid nodule FNAs. The ACR TIRADS outperformed the others, classifying more than half the biopsies as unnecessary with a FNR of 2.2%.

Abstract
BACKGROUND The 2015 American Thyroid Association (ATA) guidelines have been proposed to aid in the management of thyroid nodules by determining whether fine needle aspiration is indicated. OBJECTIVE To determine whether the ATA guidelines contribute to the overdiagnosis of thyroid cancer. PATIENTS AND METHODS This was a retrospective cohort study of ultrasound-imaged thyroid nodules (n = 1947) consecutively aspirated at a tertiary care center from 1 October 2009 to 22 February 2016. Nodules were retrospectively reviewed, assigned a 2015 ATA morphology, and placed into one of five 2015 ATA categories of risk (ATA-1, <1% risk of malignancy; ATA-2, <3% risk; ATA-3, 5% to 10% risk, ATA-4: 10% to 20% risk; ATA-5, >70% to 90% risk) by a reader who was blinded to cytology. ATA category was compared with cytopathology. The positive predictive value (PPV) of each ATA category was calculated with respect to cancer. Numbers needed to aspirate and Pearson correlations were calculated. Interrater agreement for ATA category across five readers was assessed. RESULTS The PPV for cancer increased by ATA category [category 1 to 5, respectively: 0% (0/14), 2% (4/249), 5% (36/733), 12% (104/850), 28% (28/101)]. The number needed to sample to detect one papillary cancer was 125 (ATA-2), 49 (ATA-3), 13 (ATA-4), and 5 (ATA-5). The overall interrater agreement for ATA score across all five readers was fair (intraclass correlation coefficient 0.460). CONCLUSIONS The 2015 ATA guidelines stratify risk for thyroid cancer; however, the stratification system is overly optimistic regarding cancer detection rates for the higher-risk nodules, and there is only fair interrater agreement.

Abstract
OBJECTIVE Black patients have a significantly lower incidence of well-differentiated thyroid cancer (WDTC) compared to all other race/ethnic groups, while white patients appear to be at greater risk. This study examines incidental thyroid nodules (ITNs) to assess whether racial disparities in WDTC arise from a differential discovery of ITNs-perhaps due to socioeconomic disparities-or reflect true differences in thyroid cancer rates. METHODS A retrospective review was performed of all patients who underwent fine-needle aspiration (FNA) of thyroid nodules by our academic medical center's endocrinology division between January 2006 and December 2010. Medical records were reviewed to identify whether the biopsied thyroid nodule was discovered incidentally through nonthyroid-related imaging or identified by palpation. RESULTS FNAs were performed on 1,369 total thyroid nodules in 1,141 study patients; 547 (48%) were classified as white, and 593 (52%) were classified as nonwhite. Among this cohort, 36.6% of patients underwent biopsy for an ITN. White patients were 1.6 times more likely to have undergone a biopsy for a nodule that was incidentally identified compared to nonwhites ( P<.0001). Indicators of socioeconomic status (SES) did not have a significant association with ITNs. Within the ITN cohort, 4.9% of nonwhite patients were found to have a thyroid malignancy compared to 12.9% of white patients ( P<.01). CONCLUSION The higher incidence of thyroid cancer in white patients appears to be not only due to diagnostic bias, but also to a true difference in cancer prevalence. ABBREVIATIONS FNA = fine-needle aspiration; ITN = incidental thyroid nodule; SEER = Surveillance Epidemiology and End Results; SES = socioeconomic status; WDTC = well-differentiated thyroid cancer.

Abstract
BACKGROUND/OBJECTIVE The atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS) category is one of six diagnostic categories of The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC). In this study, we report the diagnostic distribution of thyroid fine needle aspiration (FNA) cytology and analyze the outcome of AUS/FLUS cases. METHODS A total of 29,937 thyroid FNA results, reported between April 2012 and December 2016, were retrieved from the database of a medical center. We reviewed the electronic medical records and analyzed the management of these patients. RESULTS Overall frequency of AUS/FLUS is 3.1% in our laboratory, which is at the lower limit of the recommended range. Of these, 891 reports of AUS/FLUS from 770 patients were identified. Out of the 770 patients, 367 had surgical intervention. In these 367 patients, final surgical pathology yielded 204 (55.6%) malignancies, 12 indeterminateness (3.3%), and 151 (41.1%) benignity. Among these surgical patients, 113 (30.8%) had received a repeat FNA of the thyroid before thyroid resection. The difference between the malignancy rates among patients who directly received surgery after the first AUS/FLUS diagnosis (132 of 254, 52.0%) and patients having a repeat FNA before surgery (72 of 113, 63.7%) was not statistically significant. CONCLUSION Our results are in agreement with AUS/FLUS diagnoses in less than 7% of specimens, and confirm that it is appropriate to perform either a repeat thyroid FNA or thyroid lobectomy, with the clinical decision being subject to the standardized management protocols of the second edition of TBSRTC in the AUS/FLUS category.

Abstract
OBJECTIVE This study looked at the effect of a changing radiology reporting policy to routinely review the thyroid gland where visible and report on any thyroid lesion, recommending further investigation as appropriate. CONTEXT Incidentaloma is a term used to describe a lesion found on imaging unrelated to the clinical issue under investigation. There is variability in the radiological reporting of thyroid incidentalomas and conflicting recommendations as to how these lesions should be managed. DESIGN Data were collected retrospectively during a two-year period, including 12 months before and 12 months after the change in reporting policy and categorized according to whether the lesion under investigation was a thyroid incidentaloma or a symptomatic thyroid lesion. PATIENTS All patients undergoing ultrasound-guided fine-needle aspiration cytology or core biopsy were included. MEASUREMENTS The effects of the change in policy were analysed including rates of needle biopsy, rates of malignancy and subsequent surgical intervention. RESULTS There was a 122% increase in thyroid incidentalomas undergoing needle biopsy, the majority of these were detected on computed tomography. The number of malignancies increased from 1 to 4 from year 1 to year 2. All patients were >35 years old. One patient had a positron emission tomography (PET)-detected cancer, two of four of the non-PET-detected malignancies were <1.5 cm. CONCLUSION This study posits that routine radiological reporting of thyroid incidentalomas, with further investigation when clinically appropriate, is warranted. The results suggest that lesion size and CT characteristics are not reliable criteria to triage patients for investigation/biopsy.

Abstract
INTRODUCTION The fine-needle aspiration has a significant role in assessing the malignancy risk of thyroid nodules. There is uncertainty regarding the value of repeat fine-needle aspiration in benign nodules. This study aims to evaluate the concordance of results in consecutive fine-needle aspiration and to study the relevance of repetition in benign results. MATERIAL AND METHODS Retrospective study of the 4800 thyroid nodules fine-needle aspiration held in Instituto de Patologia e Imunologia Molecular da Universidade do Porto between January 1, 2014 and May 2, 2016. Of the initial sample, we selected the repeated fine-needle aspiration on the same nodule. RESULTS The first fine-needle aspiration result of the 309 nodules underwent revaluation was non-diagnostic in 103 (33.3%), benign in 120 (38.8%) and atypia/follicular lesion of undetermined significance in 86 (27.8%). The agreement between the first and second fine-needle aspiration was significantly higher in cases with an initial benign result (benign: 85.8%, non-diagnostic: 27.2% and atypia/follicular lesion of undetermined significance: 17.4%, p < 0.005). The fine-needle aspiration repeating motifs in initially benign nodules (n = 78) were repetition suggestion in 58, nodule growth in 17 and suspicious ultrasonographic features in 3. DISCUSSION The fine-needle aspiration repetition in nodules with initial non-diagnostic and atypia/follicular lesion of undetermined significance result changed the initial diagnosis in a significant proportion of patients, modifying their therapeutic approach. The high concordance of results in initially benign nodules makes fine-needle aspiration repetition not cost-effective in most cases. CONCLUSION The fine-needle aspiration should be repeated when the initial cytology result is non-diagnostic or atypia/follicular lesion of undetermined significance.

Abstract
BACKGROUND It is essential to interpret fine needle aspiration biopsy (FNAB) material correctly to create a common language among pathologists and surgeons, leading to a uniform approach to thyroid nodule management. We aimed to compare FNAB reports of patients at our institution who were treated with total thyroidectomy, before and after the Bethesda classification system. PATIENTS AND METHODS Patients who underwent total thyroidectomy for thyroid nodules are reviewed. 226 patients who underwent total thyroidectomy before the Bethesda era (2006-2009) were classified as Group-I, and 316 patients in whom total thyroidectomy was performed after the Bethesda classification system was introduced (2010-2014) were classified as Group-II. RESULTS Before Bethesda, 'nondiagnostic' or 'benign' lesions were reported in 16.4 and 45% of patients, respectively, which then significantly decreased to 4.7 and 32.9% as the Bethesda classification criteria came into use. In Group-II, the actual malignancy rates were 13.3, 2.8, 7.3, 15.5, 85.4, and 96.5% for Bethesda I, II, III, IV, V, and VI, respectively. CONCLUSION Our experience confirms that the Bethesda classification system leads to a significant reduction in lesions that used to be reported as 'benign' without compromising the actual rates of malignancy. It ensures better classification of so-called suspicious lesions, and allows for more accurate predictions of suspicious or malignant lesions.

Abstract
BACKGROUND Quality of any service is the most important aspect for the manufacturer as well as the consumer. The primary objective of any nation's health system is to provide supreme quality health care services to its patients. The objective of this study was to assess the quality of diagnostic fine needle aspiration cytology service in a tertiary care hospital. As Patient's perspectives provide valuable information on quality of process, therefore, patient's perception in terms of satisfaction with the service was measured. METHODS In this cross sectional analytical study, 291 patients undergoing fine needle aspiration cytology in Mayo Hospital were selected by systematic sampling technique. Information regarding satisfaction of patients with four dimensions of service quality process, namely "procedure, sterilization, conduct and competency of doctor" was collected through interview on questionnaire. The questionnaire was developed on SERVQUAL model, a measurement tool, for quality assessment of services provided to patients. All items were assessed on 2- point likert scale (0=dissatisfied, 1=satisfied). Frequencies and percentages of satisfied and dissatisfied patients were recorded for each item and all items in each dimension were scored. If the percentage of sum of all item scores of a dimension was ≥60, the dimension was 'good quality'. Whereas <60% was 'poor quality' dimension. Data was analysed using epi-info-3.5.1. Fisher test was applied to check statistical significance. (p-value <0.05). RESULTS Out of the 4 dimensions of service quality process, Procedure (48.8%), Sterilization (51.5%) and practitioner conduct (50.9%) were perceived as 'poor' by the patients. Only practitioner competency (67.4%) was perceived as 'good'. Comparison of dimensions of service quality scoring with overall level of patient satisfaction revealed that all 4 dimensions were significantly related to patient dissatisfaction (p<.05). CONCLUSIONS The study suggests that service quality of therapeutic and diagnostic procedures in public hospitals should be routinely monitored from the patients' point of view as most aspects of service quality in public hospitals of Pakistan, require improvements. In this manner patient's satisfaction regarding use of services in public hospitals can be made better.

Abstract
Fine-needle aspiration (FNA) is commonly used to diagnose skin disease in companion animals, but its use in horses appears to be infrequent. Equine veterinarians in western Canada were surveyed to determine their opinions about FNA and 15 years of diagnostic submissions were used to compare the perceived to actual value of FNA in the diagnosis of skin disease in horses. Practitioners viewed FNA as quick, easy, economical, and minimally invasive. However, most veterinarians rarely chose to use FNA due to a perception that sample quality and diagnostic yield were poor and there was a narrow range of diseases the technique could diagnose. Analysis of the FNA cytology samples from a veterinary diagnostic laboratory showed a wide variety of equine skin disease conditions, but the frequency of non-diagnostic results was significantly higher in equine submissions compared to those from dogs and cats.

Abstract
OBJECTIVE In this study, we aimed to determine whether preoperative thyroid fine-needle aspiration (FNA) in patients with multinodular goiter (MNG) and compressive symptoms influences the type of thyroid surgery performed, the incidence of recurrent thyroid cancer, or the need for successive surgery. METHODS We retrospectively reviewed the charts of 431 patients who underwent thyroidectomy at our institution from 2008 to 2011. Patients who presented with compressive symptoms and no prior FNA at initial presentation were included in this study. RESULTS Eighty patients met the criteria for our study, of which 46 (57.5%) underwent FNA prior to surgery and 34 (42.5%) were referred to surgery without FNA. The prevalence rates of malignancy (>1 cm) on surgical pathology in the FNA and non-FNA groups were 41% (n = 19) and 38% (n = 13), respectively. There was no statistically significant difference between the rate of total/subtotal thyroidectomies (71.7% in FNA vs. 79.4% in non-FNA, P = .31), lobectomies/partial thyroidectomies (28.3% in FNA vs. 20.5% in non-FNA, P = .43), neck lymph node dissections (P = .89) or subsequent surgeries (P = .72) between the 2 groups. CONCLUSION Our findings show that preoperative FNA in patients with an MNG and compressive symptoms does not influence the type of surgery performed, short-term outcomes, or the need for subsequent surgeries. Further studies are needed to validate the need for preoperative FNA in such patients. ABBREVIATIONS FNA = fine-needle aspiration MNG = multinodular goiter WHO = World Health Organization.

Abstract
BACKGROUND Fine needle aspiration (FNA) cytology is the method of choice to exclude malignancy in thyroid nodules. A major limitation of thyroid FNA is the relatively high rate (13-17%) of non-diagnostic samples. The aim of this study is to determine the diagnostic yield of a screw needle compared to the conventional FNA. METHODS We retrospectively analysed thyroid nodule cytology of all patients that underwent thyroid nodule fine needle or screw needle aspiration between July 2007 and July 2012 in a single academic medical centre. Cytology results were categorized according to the Bethesda classification system. RESULTS In total, 644 punctures of thyroid nodules from 459 patients were available for analysis. The screw needle was used 531 times, and the conventional fine needle 113 times. The percentage of non-diagnostic cytology was significantly lower in the screw needle samples than in the fine needle samples (3% vs 17%, P<0.001). CONCLUSION This study shows a significantly better diagnostic performance of the screw needle compared to the conventional fine needle in cytology of thyroid nodules.

Abstract
INTRODUCTION A palpable lesion in the breast is usually subjected to triple assessment (clinical examination [CE], imaging and core biopsy [CB] or fine needle aspiration [FNA]) to minimise the risk of missing breast cancer. However, breast cancer is rare in young women, and triple assessment (especially CB) is invasive and expensive. Our aim was to see whether CB/FNA could be avoided in young women with benign findings on CE and imaging. METHODS This study analysed data from a prospectively entered database on female patients aged under 25 years who attended a rapid diagnosis breast clinic over a 68-month period. RESULTS Among 10,301 patients seen, 955 females (9.3%) were aged <25 years. The most common presenting complaint was a lump, followed by pain and nipple discharge. CE was normal or revealed benign findings in all except 15 patients, in whom it was indeterminate. Ultrasonography was performed in 692 patients (72%) and was normal (n=289) or benign (n=382) in all except 21 patients, in whom it was indeterminate. In six patients, both were indeterminate. A total of 317 patients (35%) had triple assessment: FNA in 106, CB in 239 and both in 9 cases. No cancers were diagnosed. CONCLUSIONS It would appear safe to omit FNA/CB in patients aged under 25 years when clinical and ultrasonography findings are normal or benign. This approach would have avoided needle biopsies in all but 30 patients (3%) in the study.

Abstract
OBJECTIVE Numerous published guidelines have described the optimal management of thyroid cancer. However, these rely on the clinical availability of diagnostic and therapeutic modalities. We hypothesized that the availability of medical resources and economic circumstances vary in Asia-Pacific countries, making it difficult to implement guideline recommendations into clinical practice. METHODS We surveyed participants at the 2009 and 2013 Congresses of the Association of Southeast Asian Nations Federation of Endocrine Societies by distributing questionnaires to attendees at registration. RESULTS Responses were obtained from 268 respondents in 2009 and 163 respondents in 2013. Similar to the high prevalence of low-risk thyroid cancer observed in the Surveillance, Epidemiology, and End Results database, across the Asia-Pacific countries surveyed in 2009 and 2013, 50 to 100% of the respondents from the Philippines, Malaysia, Singapore, China, Taiwan, Thailand, Hong Kong, Korea, and Sri Lanka reported that more than 50% of the patients had low-risk thyroid cancer on follow-up. Importantly, there was much variation with regards to the perceived availability of investigation and treatment modalities. CONCLUSION We found a wide variation in clinicians' perception of availability of diagnostic and therapeutic modalities in the face of a rise in thyroid cancer incidence and thyroid cancer management guidelines that emphasized their importance. The lack of availability of management tools and treatments will prove to be a major barrier to the implementation of thyroid cancer management guidelines in Southeast Asia, and likely in other parts of the world as well.

Abstract
The exact frequency of non-diagnostic ultrasound-guided fine-needle aspiration (USFNA) is unknown. Clinical guidelines suggest repeating USFNA of these nodules. However, there is no specific recommendation or evidence on how and when this re-aspiration should be done. We aim to describe the approaches considered by endocrinologists to yield the highest likelihood of a satisfactory sample in solid thyroid nodules. A cross-sectional survey of The Endocrine Society (TES) and the American Thyroid Association members was conducted between October and December 2012. A total of 694 surveys were returned, 648 (93.4 %) from TES. The responders were equally divided between private and academic settings and had a high degree of expertise. Thirty-nine percent of respondents estimated the frequency of non-diagnostic USFNA to be above 10 %. For its management, 311 (46 %) recommended repeating USFNA in 1-3 months. For a second non-diagnostic USFNA, 216 (31 %) recommend surgery. The most common approaches to increase the diagnostic yield were (1) use of suction with USFNA, 18 % and (2) changing the targeted area of biopsy within the nodule, 18 %. Few considered the patients' preferences as an important driver for the management of non-diagnostic USFNA. Finally, a molecular test for bypassing non-diagnostic USFNA was regarded as the most needed strategy for future research. Variability exists in the management of non-diagnostic USFNA and strategies to increase the diagnostic yield. Testing the suggested strategies in clinical trials and understanding patient's preferences should be supported by guideline panels and funding agencies.

Abstract
The optimum technique for histological confirmation of the nature of a parotid mass remains controversial. Fine needle aspiration cytology (FNAC), which has traditionally been used, is associated with high non-diagnostic and false negative rates, and ultrasound (US)-guided core biopsy and frozen section have been explored as alternatives. US-guided core biopsy is more invasive than FNAC, but is safe, well-tolerated, and associated with improved diagnostic performance. Although frozen section offers better specificity than FNAC, it has a number of important drawbacks and cannot be considered as a primary diagnostic tool. US-guided core biopsy should be considered as the initial diagnostic technique of choice, and in units where the accuracy of FNAC is good it can be used when FNAC is equivocal or non-diagnostic.

Abstract
When calcification, frequently found in both benign and malignant nodules, is present in thyroid nodules, non-invasive differentiation with ultrasound becomes challenging. The goal of this study was to evaluate the utility of elastography in differentiating calcified thyroid nodules. Consecutive patients (165 patients with 196 nodules) referred for fine-needle aspiration who had undergone both ultrasound elastography and B-mode examinations were analyzed retrospectively. Calcification was present in 45 benign and 20 malignant nodules. On 65 calcified nodules, elastography had 95% sensitivity, 51.1% specificity, 46.3% positive predictive value and 95.8% negative predictive value in detecting malignancy. Twenty-three of 45 benign calcified nodules were correctly diagnosed with elastography compared with 4 of 45 by B-mode ultrasound. Although it is difficult to differentiate benign and malignant calcified thyroid nodules solely with B-mode ultrasound, elastography has the potential to reduce the number of fine-needle aspiration biopsies performed on calcified nodules.

Abstract
CONTEXT Novel molecular diagnostics, such as the gene expression classifier (GEC) and gene mutation panel (GMP) testing, may improve the management for thyroid nodules with atypia of undetermined significance (AUS) cytology. The cost-effectiveness of an approach combining both tests in different practice settings in North America is unknown. OBJECTIVE The aim of the study was to determine the cost-effectiveness of two diagnostic molecular tests, singly or in combination, for AUS thyroid nodules. DESIGN AND SETTING We constructed a microsimulation model to investigate cost-effectiveness from US (Medicare) and Canadian healthcare system perspectives. PATIENTS Low-risk patients with AUS thyroid nodules were simulated. INTERVENTIONS We examined five management strategies: 1) routine GEC; 2) routine GEC + selective GMP; 3) routine GMP; 4) routine GMP + selective GEC; and 5) standard management. MAIN OUTCOME MEASURES Lifetime costs and quality-adjusted life-years were measured. RESULTS From the US perspective, the routine GEC + selective GMP strategy was the dominant strategy. From the Canadian perspective, routine GEC + selective GMP cost and additional CAN$24 030 per quality-adjusted life-year gained over standard management, and was dominant over the other strategies. Sensitivity analyses reported that the decisions from both perspectives were sensitive to variations in the probability of malignancy in the nodule and the costs of the GEC and GMP. The probability of cost-effectiveness for routine GEC + selective GMP was low. CONCLUSIONS In the US setting, the most cost-effective strategy was routine GEC + selective GMP. In the Canadian setting, standard management was most likely to be cost effective. The cost of these molecular diagnostics will need to be reduced to increase their cost-effectiveness for practice settings outside the United States.

Abstract
BACKGROUND Fine needle aspiration cytology is a valuable technique in the work-up of masses arising within neck and represents a screening, inexpensive, and rapid technique to sample masses found in neck. METHODS This study included 117 cases of neck masses, subjected to fine needle aspiration cytology at the department of Pathology of a hospital in Nepal from January 2013 to December 2013. RESULTS The study included 117 patients with neck masses with median age of 37 years. The majority of the patients were in the age group of 20-29 yrs with female predominance. The most frequent cause of neck swelling is lymphadenopathy 65 (55.6%), followed by thyroid swelling 36 (30.7%), soft tissue lesion 12 (10.3%) and salivary gland lesions 4 (3.4%). The most common lesion in these patients was non-neoplastic, followed by malignant neoplasm. Tuberculosis is the most common cause of neck lymphadenopathy and colloid goiter is the commonest cause of thyroid swelling. In soft tissue, abscess is the most frequent one. Pleomorphic adenoma is more common than other salivary gland lesions. CONCLUSIONS Lymphadenopathy is commonest cause of neck mass, followed by thyroid gland & soft tissue swellings. Tuberculosis is the most common diagnosis of neck masses, followed by colloid goiter. Fine needle aspiration cytology is pretty accurate technique to diagnose neck masses and it is helpful to avoid unnecessary surgeries and in general clinical management and it is recommended as a first line of investigation in the diagnosis of neck masses.

Abstract
BACKGROUND The diagnostic and therapeutic procedures performed in a series of patients with primary parapharyngeal space (PPS) tumours treated at the ENT Departments of San Giovanni Bosco Hospital, Turin, and of the Pugliese-Ciaccio Hospital, Catanzaro, Italy, in the period 2001-2010 are evaluated. MATERIALS AND METHODS The retrospective review included 20 patients, 11 male and 9 female, average age of 41 years operated on for 21 primary PPS tumours. The most common tumours found were neurogenic neoplasms, while those of salivary origin were the next most common. RESULTS There were 14 paragangliomas (7 originating from carotid glomus, 5 from vagal and 2 from tympanicum), 1 sympathetic chain schwannoma and 6 pleomorphic adenomas. All the tumours were benign in nature and gave rise to few signs or symptoms. Patients underwent preoperative computed tomography (CT) scan or magnetic resonance imaging (MRI) or both. Most contrast-enhanced masses were submitted to some type of angiography. Most of the surgeries were planned through imaging alone, as preoperative fine needle aspiration (FNA) biopsy was performed only in six cases. Four different approaches were adopted for tumour removal: transcervical, transcervical/transparotid, cervical-transparotid-transmandibular and infratemporal fossa approach. There was no operative mortality, though neurologic morbidity was significant. Follow-up, extended to a maximum of 11 years, did not reveal any recurrences. In conclusion, neurogenic tumours may be the most common of PPS masses. Surgery is the mainstay treatment and external approaches offer the potential for satisfactory tumour resection. Of such external approaches, transcervical and cervical/transparotid are the most often used in benign forms. CONCLUSION The number of perioperative complications encountered in this series confirms the difficulty of performing surgery in this complex area, even in benign cases. The chances of avoiding vascular damage and saving the trunks or most of the nerve fibres involved depend not only on the skill and experience of the surgeon but also on the anatomy of the lesion, the type of connection between the tumour and the nerve from which it originates and the distribution of neural fibres in or around the tumour mass.

Abstract
Sentinel node biopsy (SNB) has largely replaced axillary lymph node dissection (ALND) as the standard-of-care for nodal staging in invasive breast cancer. Preoperative imaging-based staging of the axilla using ultrasound with selective ultrasound-guided needle biopsy (UNB) is moderately-sensitive and identifies approximately 50% of patients (pooled estimate from meta-analysis 50%; 95% confidence interval=43%-57%) with axillary nodal metastases prior to surgical intervention. It is also a highly specific staging strategy that allows patients to be triaged to ALND based on a positive result (positive predictive value approximates 100%), thus avoiding two-stage axillary surgery and unnecessary SNB. Axillary UNB has a good clinical utility: based on an updated meta-analysis, we found that a median proportion of 18.4% (inter-quartile range=13.3%-27.4%) from 7,097 patients can be effectively triaged to axillary treatment and can avoid SNB. However, the changing algorithm of axillary surgical treatment means that UNB will have relatively less utility where surgeons omit ALND for minimal nodal metastatic disease. Research that allows enhanced application of ultrasound and UNB to specifically identify and biopsy sentinel nodes and to discriminate between patients with minimal versus advanced nodal metastatic involvement is likely to have the most impact on future management of the axilla in breast cancer.

Abstract
BACKGROUND To provide population-based estimates of trends in thyroid nodule fine-needle aspirations (FNA) and operative volumes, we used multiple claims databases to quantify rates of these procedures and their association with the increasing incidence of thyroid cancer in the United States. METHOD Private and public insurance claims databases were used to estimate procedure volumes from 2006 to 2011. Rates of FNA and thyroid operations related to thyroid nodules were defined by CPT4 codes associated with International Classification of Diseases, Ninth Revision Clinical Modification codes for nontoxic uni- or multinodular goiter and thyroid neoplasms. RESULTS Use of thyroid FNA more than doubled during the 5-year study period (16% annual growth). The number of thyroid operations performed for thyroid nodules increased by 31%. Total thyroidectomies increased by 12% per year, whereas lobectomies increased only 1% per year. In 2011, total thyroidectomies accounted for more than half (56%) of the operations for thyroid neoplasms in the United States. Thyroid operations became increasingly (62%) outpatient procedures. CONCLUSION Thyroid FNA and operative procedures have increased rapidly in the United States, with an associated increase in the incidence of thyroid cancer. The more substantial increase in number of total versus partial thyroid resections suggests that patients undergoing thyroid operation are perceived to have a greater risk of cancer as determined by preoperative assessments, but this trend could also increase detection of incidental microcarcinomas.

Abstract
BACKGROUND Endoscopic ultrasonography (EUS) and Endoscopic Retrograde Cholangiopancreatography (ERCP) are often required in patients with pancreaticobiliary disorders. AIMS To assess the clinical impact and costs savings of a single session EUS-ERCP. METHODS Patient and intervention data from April 2009 to March 2012 were prospectively recruited and retrospectively analyzed from a database at a tertiary hospital. Indications, diagnostic yield, procedure details, complications and costs were evaluated. RESULTS Fifty-five scheduled combined procedures were done in 53 patients. The accuracy of EUS-fine needle aspiration for malignancy was 90%. The main clinical indication was a malignant obstructing lesion (66%). The ERCP cannulation was successful in 67%, and in 11/15 failed ERCP (73%), drainage was completed thanks to an EUS-guided biliary drainage: 6 transmurals, 5 rendezvous. Eight patients (14%) had related complications: bacteremia (n = 3), pancreatitis (n = 2), bleeding (n = 2) and perforation (n = 1). The mean duration was 65 ± 22.2 min. The mean estimated cost for a single session was €3437, and €4095 for two separate sessions. The estimated cost savings using a single-session strategy was €658 per patient, representing a total savings of €36,189. CONCLUSION Combined EUS and ERCP is safe, technically feasible and cost beneficial. Furthermore, in failed ERCP cases, the endoscopic biliary drainage can be completed with EUS-guided biliary access in the same procedure.

Abstract
AIM The aim of this study was to evaluate the correlation between preoperative thyroid fine-needle aspiration result and final histopathology in patients with thyroid nodules. METHODS The medical records of 298 patients (mean age, 47.7±12.3 years; 79.5% females) who underwent fine-needle aspiration for thyroid nodules and who were operated and have final pathological diagnosis were retrospectively reviewed. For reporting fine-needle aspiration specimen pathology, the Bethesda thyroid fine-needle aspiration classification was used. Tyroglobulin (Tg) and anti-Tg and anti-thyroid peroxidase (anti-TPO) antibody levels were determined preoperatively. RESULTS Thyroid nodules were non-diagnostic, benign or atypia (Bethesda groups 1-3) in 76.8% of patients; and follicular neoplasm, suspicious for malignancy or malignant (Bethesda groups 4-6) in 23.1% of patients. Final pathology of surgery specimen was most commonly nodular goiter (36.6%) and papillary carcinoma (35.6%). Nodular goiter was significantly more prevalent in Bethesda 1 group while papillary carcinoma was more common in Bethesda 3 group (P<0.05). Tg level is significantly higher in the nodular goiter group (90.49±126.93 ng/mL), while anti-Tg and anti-TPO levels are significantly higher in the lymphocytic thyroiditis goiter group (229.77±494.42 U/mL and 282.86±360.77 U/mL, respectively) than the other pathology groups (P<0.05 for all). CONCLUSION Papillary carcinoma is more common in Bethesda thyroid fine-needle aspiration classification 3 group. Therefore, preoperative fine-needle aspiration for thyroid nodules is predictive of final pathology and should be applied for diagnosis and follow-up.

Abstract
BACKGROUND Although the Bethesda System for Reporting Thyroid Cytopathology (BSRTC) has standardized the diagnostic terminology for thyroid fine-needle aspiration (FNA), morphological interpretation remains subjective, and interobserver discrepancies are expected. This study quantifies the frequency and magnitude of these discrepancies in a single tertiary center's experience and elucidates key factors that are associated with changes in diagnosis. METHODS Institutional consultation for 3885 thyroid cytological samples over 45 months were reviewed. BSRTC classification made by the sending institution was compared with that of our institution. An ANOVA was performed to determine factors that may be associated with interinstitutional diagnostic differences. Histopathology diagnoses were available for 1049 (27%) nodules; the malignancy rates for inside and outside BSRTC classifications were calculated. RESULTS There were 937 1-step changes and 301 ≥2-step diagnostic discrepancies comprising 24% and 8% of all cases, respectively. Second review decreased the indeterminate rate 38% to 28% (P < .000001). Indeterminate diagnostic category before second review, low specimen cellularity, Hashimoto's thyroiditis, and low volume of consults from the sending institution were associated with discordance. Of the 1049 thyroid nodules operated for which unequivocal histopathology was available, the malignancy rates for the BSRTC categories before and after second review were compared. Categorical upgrades were associated with a malignancy rate of 84%, whereas downgrades were associated with a malignancy rate of 38% (P < .000001). CONCLUSION This is the largest series to date of thyroid cytology second review. The BSRTC classification changed 32% of the time, potentially resulting in significant changes in clinical and surgical management. Because certain specimen characteristics (indeterminate diagnostic category before second review, low specimen cellularity, Hashimoto's thyroiditis, and low volume of consults from the sending institution) were particularly associated with a diagnosis change, morphological second review may be of potential benefit in these settings.

Abstract
PURPOSE To determine the optimal number of biopsies in patients with non-obstructive azoospermia (NOA) who undergo testicular sperm extraction (TESE), and assess the impact of testicular histology on outcome. MATERIALS AND METHODS Seven hundred and forty-one patients with NOA who underwent TESE in our institution were enrolled in the study. Testicular sperm extraction was performed applying an open surgical technique on the larger testis. The number of biopsies varied according to the presence or absence of spermatozoa. No further biopsies were obtained once spermatozoa were detected. If no spermatozoa were seen, the procedure was continued to a maximum number of 5 biopsies, including a single biopsy of the contralateral testis. RESULTS Spermatozoa were obtained in 330 (44.5%) patients after a single biopsy. The success rate increased to 381 (51.4%), 416 (56.1%), 433 (58.4%), and 441 (59.5%) after the second, third, fourth, and contralateral sampling, respectively. Multiple sampling increased the success rate; however, success rate did not increase considerably after the third sampling. Performing contralateral testicular biopsy was advantageous in patients with uniform or mixed pattern hypospermatogenesis. CONCLUSION We recommend performing at least 3 biopsies in patients with NOA who undergo TESE. Further biopsies may also be advantageous when the NOA is a consequence of either uniform or mixed pattern hypospermatogenesis.

Abstract
To study the efficacy of fine needle aspiration cytology as a diagnostic tool and also to find out the incidence of auto-immune thyroiditis in Burdwan a prospective study was undertaken among 131 patients with thyroid swelling presented to the department of ENT, Burdwan Medical College and Hospital, Burdwan, a rural based medical college. All patients underwent fine needle aspiration cytology. Out of them satisfactory aspirates were obtained in 130 cases. There were 31 cases (23.84%) of auto-immune thyroiditis among 130 cases. Auto-immune thyroiditis is the archetype for organ-specific auto-immune disorders. Incidence of auto-immune thyroiditis is increasing day by day. Their accurate diagnosis and management needs a team approach. The incidence of auto-immune thyroiditis patients is high in Burdwan Medical College and Hospital.

Abstract
PURPOSE The purpose was to compare the frequency of metastatic and nonmetastatic lymph nodes diagnosed by fine needle aspiration biopsy cytology (FNAC) and thyroglobulin concentration from fine needle aspiration biopsy washout fluid (FNAB-Tg) in an indeterminate range (0.2-100 ng/mL), and to evaluate the most appropriate threshold value of FNAB-Tg in an indeterminate range. MATERIALS AND METHODS We performed ultrasound-guided FNAB and FNAB-Tg in suspicious metastatic cervical lymph nodes of papillary thyroid carcinoma and performed surgery. Ninety-five lymph nodes with indeterminate values of FNAB-Tg ranging from 0.2-100 ng/mL in ninety-two patients were included in this study. The diagnostic performances in multiple Tg levels (0.7, 1.0, 5.0, 10.0, 20.0, 50.0) were evaluated to compare with FNAB cytology using sensitivity, specificity, and accuracy with area under the curve (AUC) analysis. RESULTS Forty-two were metastatic lymph nodes and fifty three were nonmetastatic lymph nodes. FNAB-Tg ranged from 0.22 to 90.9 ng/mL in metastatic lymph nodes (mean; 34.3 ± 33.3 ng/mL) and 0.20 to 56.7 ng/mL in nonmetastatic lymph nodes (mean; 4.9 ± 11.1 ng/mL) (p<0.001). The most excellent diagnostic performance was displayed in 5 ng/mL of FNAB-Tg with AUC of 0.76, sensitivity, specificity, accuracy, 69.0, 83.0, and 76.8, respectively. However, there was no significant difference from 10 ng/mL FNAB. CONCLUSION We ascertained that 5 ng/mL yielded the most excellent diagnostic performance among FNAB-Tg levels in the present setting with a large series with the indeterminate range (0.2-100 ng/mL) of FNAB-Tg values. These results need additional confirmation under different laboratory conditions.

Abstract
OBJECTIVE We aimed to evaluate the prognostic value of thyroid fine needle aspiration biopsy (FNAB) in the diagnosis of pathologic lesions. METHODS Data from 1 078 consecutive patients (female : male ratio, 9:1) who underwent thyroidectomy were retrospectively analyzed. All patients had preoperative thyroid FNAB. Unilateral and bilateral FNAB were performed in 872 and 206 patients, respectively, resulting in 1 284 cytologic aspirates, which were compared to postoperative histology. Risk factors for malignancy (age, sex, single nodule, or nodule in multinodular goiter) were evaluated. RESULTS 203 (15.81%) aspirates were non-diagnostic. 768 (59.81%) were benign; 112 (8.72%) were atypical; 170 (13.24%) were follicular neoplasms, 5 (0.4%) had suspicion of malignancy; and 26 (2.02%) were malignant tumors on FNAB. The calculated risk of malignancy in each group was: 1.97%, 1.84%, 7.15%, 12.35%, 60%, and 100%. There were 2.02% false negative and 0.15% false positive results. Diagnostic discrepancies occurred in the follicular neoplasm group, of 86 biopsies (0.15%). CONCLUSION FNAB is the primary method of preoperative diagnostics of thyroid tumors, as it allows many patients to avoid thyroidectomy. In addition, it helps the operating surgeon to decide the extent of surgical resection.
