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.

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.

ABSTRACT Cytodiagnostic fine needle aspiration biopsy specimens from toxic goitres were studied for signs of lymphoid infiltration. Comparison with histological sections of specimens obtained by surgery showed that an excess of lymphoid cells in the aspirate smears corresponded to a large number of lymphoid foci in these sections. Excess of lymphoid cells in the fine needle aspirates was also positively correlated with the occurrence of circulating thyroid antibodies against thyroglobulin and/or cytoplasmic antigen, but not with the presence of the long-acting thyroid stimulating factor, LATS. It also varied with age in that it was most common in the youngest patients and in patients between 40–55 years, while lymphoid infiltration was seldom seen in patients over 55 years. A finding of practical clinical interest was that in toxic goitres with cytological signs of lymphoid infiltration hyperthyroidism had less tendency to recur after treatment with thiocarbamide drugs than in those without such signs.
