The Bethesda System for Reporting Thyroid Cytopathology is a standardized reporting system for classifying thyroid fine-needle aspiration results comprising of 6 diagnostic categories with unique risks of malignancy and recommendations for clinical management. The majority of thyroid nodules are benign; however, up to 30% of fine-needle aspiration of thyroid nodule results are equivocal. Until 2007, various diagnostic terms were used to classify such cases, including "atypical," "indeterminate," and rule-out or cannot exclude malignancy. A literature review of 13 original studies was conducted to evaluate whether utilization of the Bethesda System for Reporting Thyroid Cytopathology nomenclature represent an improvement over thyroid cytopathology reporting schemes used before 2007 in diagnosing thyroid malignancy. The sensitivity and specificity of thyroid fine-needle aspiration was high in the studies that assessed the measures. However, a selection bias exists and most studies do not include indeterminate diagnosis in their calculations. Although the Bethesda System for Reporting Thyroid Cytopathology recommends a repeat fine-needle aspiration to follow-up nondiagnostic specimens, in the majority of studies, an appreciable number of cases underwent follow-up surgical biopsy or thyroidectomy. The diagnostic category of atypia/follicular lesion of undetermined significance remains heterogenous in terms of usage and clinical outcome. The majority of the studies that utilize the Bethesda System for Reporting Thyroid Cytopathology in this literature review retrospectively reclassified thyroid fine-needle aspiration into the Bethesda System for Reporting Thyroid Cytopathology nomenclature with reported malignancy rates that are similar between cases reclassified as atypia/follicular lesion of undetermined significance and follicular neoplasm/suspicious for follicular neoplasm.  相似文献

Via routinely used thyroid function tests, scintigraphy and ultrasonography (USG), important information is obtained in the clinical and diagnostic practice for thyroid nodules. However, the distinction between benign and malignant lesions cannot precisely be performed with these tests. Thyroid fine needle aspiration biopsy (FNAB) is considered the most reliable diagnostic method in the differentiation between benign and malignant thyroid nodules. It has recently been likely to perform aspiration from deeper nodules via the implemention of FNAB along with USG. Today, in cytopathological examination of thyroid FNAB, standardized Bethesda System for Reporting Thyroid Cytopathology (BSRTC) system is used. Here, FNAB was performed in 1096 patients with thyroid nodules in the Medical School of Selcuk University between January 2009 and July 2014. Patients consisted of 919 women and 177 men between 12 and 87 years of age. Evaluated via BSRTC, the results were classified as unsatisfactory, benign, atypia (or follicular lesions) of undetermined significance (AUS), follicular neoplasm or lesions suspicious for follicular neoplasm (FN), suspected malignant and malignant. After FNAB, 183 patients were operated and evaluated histopathologically. Histological malignancy rates of the categories were as follows: 16% (5), 15% (6) 14% (1) 60% (9), 72% (18) and 97% (63), respectively. In our study, we aimed to compare FNAB results of thyroid nodules with histopathology results after thyroidectomy and to show the sensitivity and specificity of FNAB technique to be higher in the follow-up and diagnosis of thyroid lesions. Given the malignancy detection rate in the follow-up of patients whose cytology was reported as inadequate, we also consider follow-ups are important in these patients.  相似文献

Purpose: The management criterion of thyroid nodules is to evaluate the risk of malignancy, based on cytological examinations. Ultrasound-guided fine-needle aspiration biopsy (US-FNAB) has a highly diagnostic value for thyroid nodules. The aim of this study was to compare the efficacy of US-FNAB for thyroid nodules with different sizes. Material and methods: From August 2013 to November 2013, 344patients with thyroid nodules who had undergone US-FNAB were divided into three groups, according to the largest diameter of their nodules (group A, ≤ 5.0 mm; group B, 5.1-10.0 mm; group C, > 10.0 mm). All the nodules were subsequently verified by histology or follow-up findings. The accuracy, sensitivity, specificity, positive predictive value, negative predictive value of aspiration cytology in each group was compared. Results: Among 344 thyroid nodules diagnosed by cytology, the cytology was classified as nondiagnostic or unsatisfactory for 53 (15.4%) lesions, benign for 144 (41.9%) lesions, atypia of undetermined significance or follicular lesion of undetermined significance for 20 (5.8%) lesions, follicular neoplasm or suspicious for a follicular neoplasm for 26 (7.6%) lesions, suspicious for malignancy for 36 (10.5%) lesions, malignant for 65 (18.9%) lesions. There were 243 benign and 101 malignant nodules confirmed by the pathological or follow-up ultrasound. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value were confirmed to be 87.5% (14/16), 92.5% (37/40), 91% (51/56), 82.3% (14/17), and 94.8% (37/39) in group A; 92.3% (36/39), 96.9% (94/97), 95.5% (130/136), 92.3% (36/39), and 96.9% (94/97) in group B; and 91.3% (42/46), 93.4% (99/106), 92.7% (141/152) 85.7% (42/49), and 96.1% (99/103), in group C. There were no statistical differences in accuracy, sensitivity, specificity, false positive accuracy, false negative rate of fine needle aspiration of thyroid nodules with different sizes (P > 0.05). Conclusion: US-FNAB has similar diagnostic efficacy to thyroid nodules with different sizes.  相似文献

There are papers suggesting the complementary role of core needle biopsy (CNB) in the diagnosis of thyroid nodules. By comparing the result of CNB and fine needle aspiration (FNA) cytology performed in consecutive cases of thyroid nodules, the role of CNB was evaluated. Retrospective reviews of 2131 FNA and 275 CNB which were performed as first-line biopsy for 2406 thyroid nodules in 2187 patients were performed. The ultrasound (US) feature of thyroid nodule was classified following the risk of malignancy suggested by American Thyroid Association (ATA) guideline. Rate of unsatisfactory and cellular atypia could be decreased significantly by first-line CNB in all US group, and the nodules with highly suspicious feature showed significant decrease in inconclusive result by first-line CNB. However, increased rates of architectural and follicular neoplasm (FN) were identified in CNB group especially in intermediate and low suspicious nodules, and the first-line CNB could not decrease the inconclusive result in these US groups. The diagnostic rate of neoplasm diagnosed by surgery following the result of architectural atypia or FN was not different between FNA and CNB even with significantly higher rate in CNB group. Furthermore, the sensitivity for follicular neoplasm (21.2 vs. 61.9%) was significantly higher in CNB group. The CNB can be considered in nodules with highly suspicious feature with advantage of significantly lower inconclusive diagnostic rate than FNA group. However, significantly increased diagnosis of architectural atypia or FN in other nodules by CNB is recognized and should be evaluated in future to understand the meaning.  相似文献

Asymptomatic incidental thyroid nodules (thyroid incidentalomas) are found in up to a third of the adult population. There is notable overlap in the sonographic appearance of benign and malignant thyroid nodules. This paper provides a brief review of the ultrasound findings of thyroid nodules that are suspicious for malignancy with pathologic correlates. We then discuss the standard approach to a fine needle aspiration biopsy of a thyroid nodule at our institution. Finally, we review specific diagnostic challenges in image guided fine needle aspiration biopsies. Diagn. Cytopathol. 2013;41:1107–1114. © 2013 Wiley Periodicals, Inc.  相似文献

Objective: To compare the cytological findings of hypoechoic thyroid nodules with intranodular vascular pattern (pattern II) obtained by two different needles (Neolus 25 gauge, Chemil, Wenzhou, China vs Yale Spinal 25 gauge, Becton Dickinson, Madrid, Spain) in euthyroid patients and to evaluate their cost-effectiveness. Methods: From January 2001 to December 2003, 480 euthyroid patients with a hypoechoic thyroid nodule pattern II were referred for US-FNAC. The nodules were alternatively evaluated by Neolus or by Yale Spinal with the stylet (YS+) or without the stylet (YS−), in order to evaluate if the cytological results could be due to the presence of the stylet or to the different length of the two needles. For each nodule two passes were performed and the material was obtained by capillary action. Material was smeared on slides, fixed, and stained by Papanicolaou techniques. Cytological specimens were evaluated in blind by the same experienced cytopathologist. Results: Inadequate cytological specimens because of blood contamination were present in 30 (18.7%) samples by Neolus needle and in 22 (13.8%) by YS− compared to only 5 (3.1%) by YS+. In 6 (20%) cases of the 30 repeated US-FNAC by Neolus and in 4 (18%) of the 22 US-FNAC by YS−, material remained inadequate for diagnosis because of blood contamination. All the five repeated samples obtained by YS+ became adequate for diagnosis and resulted benign nodules. Direct costs of US-FNAC procedure are currently Э 72.30 including cytological examination. The cost of Neolus and Yale needles is Э 0.19 and Э 3.0, respectively. The estimated total cost to obtain a cytological diagnosis by a Neolus needle (160 + 30 repeated US-FNAC) was Э 13809.2 vs Э 12919.5 by Yale Spinal needle (160 + 5 repeated US-FNAC). Conclusion: This study demonstrates that the use of Yale Spinal needles greatly reduces inadequate cytological specimens, and therefore limits both direct and indirect costs.  相似文献

Early detection and diagnosis of papillary thyroid carcinoma are important for successful management of patients. Liquid-based preparations (Thinprep) of fine needle aspirations from thyroid nodules are now widely used and are replacing conventional smears because residual samples can be used for ancillary tests. Detection of the BRAF(V600E) mutation in cytology specimens could aid in the diagnosis of papillary thyroid carcinoma. We, therefore, analyzed the cytologic features and BRAF(V600E) mutation status of thyroid liquid-based preparation-fine needle aspiration samples. A total of 191 histologically confirmed thyroid liquid-based preparation-fine needle aspiration specimens were selected. We analyzed cytomorphological features and BRAF(V600E) mutation status in both liquid-based preparation-fine needle aspiration samples and the corresponding formalin-fixed, paraffin-embedded tissues. The Seeplex BRAF ACE detection kit (Seoul, Korea), melting curve analysis with SYBR green, and sequencing analysis were used to detect BRAF(V600E) mutations. Of 191 patients, 126 had histologically confirmed papillary thyroid carcinoma, whereas the remaining 65 lesions were benign lesions and carcinomas of other types. The sensitivity of liquid-based preparation alone for diagnosis of papillary thyroid carcinoma was 71.4%. When BRAF(V600E) mutation analyses results were considered in conjunction with the cytologic diagnosis, the diagnostic sensitivity for detecting papillary thyroid carcinoma increased to 84.9% regardless of the method used to detect BRAF mutations. BRAF(V600E) mutation analysis using residual liquid-based preparation cytologic samples is, therefore, a powerful additional diagnostic tool for diagnosis of papillary thyroid carcinoma.  相似文献
