ABSTRACT FNAC though considered the gold standard diagnostic test in the evaluation of a thyroid nodule, has many issues regarding the terminologies and interpretation. The National Cancer Institute (NCI) hosted the NCI Thyroid Fine needle Aspiration State of the Science Conference in 2007, which acknowledged the importance of developing a uniform terminology for reporting thyroid FNA results to facilitate effective communication among cytopathologists, endocrinologist, surgeons, radiologists and other healthcare providers. The NCI Conference concluded the terminology and morphologic criteria which formed the framework for The Bethesda system for reporting thyroid cytopathology (TBSRTC). It is a 6 tiered ‘The Bethesda System for Reporting Thyroid Cytopathology’ (TBSRTC) for unifying the terminology and morphologic criteria along with the corresponding risk of malignancy. Bethesda also offers management approach for all the categories. Bethesda system is presently widely accepted in western countries and is being introduced in rest of the world. This system of reporting undoubtedly represents a major step toward standardization, reproducibility and ultimately improvement in clinical significance, usefulness and predictive value of thyroid FNAC. The problems faced by the cytopathologist while implementing Bethesda during reporting are centred on AUS/FLUS category. The heterogeneity of this low-risk category leads to significant variability in its reported percentage as well as reported rate of malignancy. How to cite this article Dhume V, Kavishwar V.

Background: It has been reported that African-Americans (AA) have a higher prevalence of overall malignancy compared to Caucasians, in the United States, yet the incidence of thyroid malignancy is half. The aim of this study is to assess the rate of malignant versus benign thyroid disease in AA from an urban-based hospital with an academic setting. Our study analyzed the AA population with respect to fine needle aspiration (FNA) of thyroid lesions, in correlation with final surgical pathology. This is the first study of its kind to our knowledge. Design: We retrospectively reviewed thyroid FNA cytology between January 2005 and February 2011. Consecutive FNA specimens with corresponding follow-up surgical pathology were included. The patients were categorized as African- American (AA) and Non-African-American (NAA), which included Caucasians (C), Hispanics (H), and Others (O). The FNA results were classified using the latest edition of The Bethesda System for Reporting Thyroid Cytopathology (TBS-Thy) and the follow-up surgical pathology was used for the final categorization. Results: We studied 258 cases: 144 AA (56%) and 114 NAA [43 C (17%), 3 H (1%), and 68 O (28%)]. The average age for AA was 51 years (range 20 – 88) and for NAA was 53 years (range 25 – 86). There were more females than males in the AA versus the NAA group (85 vs. 75%). The incidence of thyroid lesions in the FNA specimens was similar between these two populations. The distribution of benign versus malignant diagnosis on follow-up surgical pathology was examined across TBS-Thy class. Conclusion: Our data suggest that distribution of benign versus malignant lesions in the thyroid FNA of AA versus NAA, with follow-up surgical pathology, is comparable for TBS-Thy classes, non-diagnostic (I), benign (II), suspicious for malignancy (V), and malignant (VI) in AA versus NAA.

The Impact

Abstract Objectives Long-term follow-up is important for determining performance characteristics of thyroid fine-needle aspiration (FNA). Methods Histologic or 3 or more years of clinical follow-up was used to calculate performance characteristics of thyroid FNA before and after implementation of The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC). The impact of noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) classification was also investigated. Results Follow-up was obtained for 1,277/1,134 and 1,616/1,393 aspirates/patients (median clinical follow-up, 9.9 and 4.4 years, pre- and post-TBSRTC, respectively). Nondiagnostic, suspicious for follicular neoplasm, and suspicious for malignancy (SFM) diagnoses decreased and benign diagnoses increased post-TBSRTC, while atypical rate remained less than 1%. Negative predictive value for benign nodules and positive predictive value (PPV) for SFM increased significantly. Eleven nodules were reclassified as NIFTP, slightly decreasing PPV/risk of malignancy (ROM). Conclusions Appropriate ROM for thyroid FNA can be achieved through application of TBSRTC terminology with minimal use of atypical category.

Background: An encouragement for the thyroid proposal was the Bethesda system for reporting cervical cytology interpretations, a uniform reporting system for thyroid FNA will facilitate effective communication among health care providers. The objective of the present study was to classify thyroid lesions in various categories under Bethesda system correlating the cytological findings in various thyroid lesions with clinical and radiological details.Methods: A retrospective study on FNAC thyroid was performed in a tertiary hospital and a Medical teaching institution in Mumbai, Maharashtra, India which included cases which were reported from 1st January 2010 to 31st July 2011. For cytomorphological analysis, all smears (Papanicolaou and MGG) were reviewed and cases were categorized into six Bethesda categories. The FNAC findings were correlated with clinical, radiological and laboratory findings. Discrepancies between original diagnosis and review diagnosis as well as difficulties encountered during application of Bethesda were studied in detail.Results: Total 413 FNACs were received during the study period. The original diagnoses included 10 different categories or labels some of which were descriptive. On application of Bethesda, maximum cases were found in category II (82.32%) followed by category I i.e. inadequate (7.7%). Category III (Atypia of Undetermined significance) included wide spectrum of cases which were previously diagnosed as goitre, suspicious or neoplastic.Conclusions: Bethesda system of reporting thyroid FNAC has brought uniformity in cytology reporting. It has facilitated better understanding between cytopathologist and clinicians as every category connotes specific risk of malignancy and recommends treatment.
