Objective: Diagnostic frequency ratios such as the atypia of undetermined significance (AUS):malignant ratio are touted to be useful for laboratory precision benchmarking. We therefore sought to examine their reproducibility and usefulness at a tertiary hospital. Methods: We reviewed thyroid fine-needle aspirates (FNA) submitted to our institution from outside laboratories and evaluated the ability of diagnostic frequency ratios to capture the complexity of The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC). Specifically, we evaluated the ability of the AUS:malignant ratio to describe the frequencies of the other TBSRTC diagnoses. Results: A total of 2,784 cases from 19 laboratories were included. The use of the AUS category varied the most. There was insufficient reflection of the non-AUS nonmalignant TBSRTC diagnostic frequencies in our analysis, and these results do not appear to arise from observer variability in the outside laboratories. Conclusion: Diagnostic frequency ratios are not reproducible in our experience and fail to describe the other TBSRTC categories. As such, they are unlikely to prove sufficient for benchmarking laboratory precision with TBSRTC.

The present study was a two year prospective study of FNAC of total 158 palpable thyroid lesions, reported according to The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC). Out of 158 cases, 36 patients underwent surgical excision and cyto- histopathological correlation was done in these cases. Majority of the patients were females, with a ratio of female to male as 8.9:1. The duration of the palpable thyroid swelling in the present study ranged from less than 1 month period to more than 5 years. Size of thyroid swelling varied from as small as 1 cm to as large as 18 cm in diameter. The procedure was done by both aspiration and non-aspiration techniques and any significant difference in terms of the yield of material by either of the method, was not observed in the present study. TBSRTC is an excellent reporting system, as it showed specificity of 100 % in the present study, which helped to diagnose benign cases correctly and to avoid unnecessary surgery.

Context.—The Bethesda System for thyroid fine-needle aspirates does not account for the size of the lesion that is aspirated. Objective.—To determine whether the size of the lesion would be helpful in order to reduce indeterminate thyroid aspirations. Design.—We correlated the results of all thyroid aspirations and surgical resection for the last 16 years at our institutions. Results.—A total of 9080 cases were aspirated and 1393 resections were performed. Of those resected, a total of 236 (17%) were classified as atypical follicular cells of undetermined significance, and 256 (18%) were classified as suspicious for a follicular/Hürthle cell neoplasm. A total of 52 incidental papillary carcinomas were identified in these indeterminate cases at resection (52 of 492; 11%). Thirty-seven (16%) atypical follicular cells of undetermined significance cases and 21 (8%) suspicious for a follicular/Hürthle cell neoplasm cases were for nodules smaller than 1 cm in diameter. When cases subtyped as atypical, a papillary carcinoma cannot be ruled out, were removed (13 cases), the remaining 24 and 21 aspirates identified 3 tumors each (13% and 14%), all papillary carcinomas. Together, the incidence of identified carcinomas was not significantly different than that of incidental carcinomas (13% versus 11%, P = .48). The rate of identified carcinomas was significantly less than for similar indeterminate cases smaller than 1 cm (excluding cases of atypical, papillary carcinoma cannot be ruled out) (88 of 330 cases; 27%; P = .05). Conclusions.—For nodules smaller than 1 cm in our series, indeterminate aspirates without features of papillary carcinomas have the same risk of malignancy as benign aspirates.

Introduction: Thyroid nodules are very common. Many are detected incidentally due to increased head and neck imaging. The majority are benign; however, malignancy can’t be excluded in many cases and tissue sampling is needed. Ultrasound guided fine needle aspiration is an easy and effective way to sample g thyroid nodules. Inadequate sampling was reported in 10-40% of the cases. Rapid On-site Evaluation (ROSE) was proposed to assess obtained sample for adequacy. The aim of this study is to identify the benefit of applying ROSE with US-FNA of thyroid nodules within our institution. Materials and methods: Patients who underwent FNA for thyroid nodules with ROSE availability documented in their procedure note between January 2017 to December 2018 were retrospectively included. All procedures were done by experienced radiologists. Aspirated material was Diff Quik stained for immediate evaluation. The final cytological diagnosis and specimen adequacy was based on The Bethesda system for reporting thyroid cytopathology. Specimen adequacy was compared between ROSE and non-ROSE groups. Results: 442 thyroid nodules were biopsied. ROSE was available for 65 nodules. Non-diagnostic rate with ROSE was 10.8% compared to 13.8% without ROSE with the difference being statistically insignificant. ROSE availability improved sample adequacy of nodules less than 3 cm with statistically significant difference of 100.0% with ROSE vs. 87% without ROSE. Conclusion: The current study does not justify the routine use of ROSE. However, ROSE availability is beneficial with smaller sized thyroid nodules and less experienced radiologists performing the procedure. Doi: 10.28991/SciMedJ-2021-0301-1 Full Text: PDF
