Abstract
Background: Objectives: to determine the stratification and risk of malignancy of Bethesda system’s subgroups for reporting thyroid cytopathology, in addition, compare with Thyroid Imaging Reporting and Data System [TI-RADS] in diagnosing benign and malignant thyroid nodules.
Method: - Retrospective cross - sectional descriptive study. Collect data of 202 thyroid nodules from 193 patients admitted at the Hospital of in Hue University of Medicine and Pharmacy during the period 6/2018 to 5/2020.
Results: The average age uns 46.7 ± 14.5 years, women accounted for the majority (89.6%) and most patients had multiple thyroid nodules (79.2%). The proportion of Bethesda subgroups were : 0% (I); 38.6% (II); 0.5% (III); 30.2% (IV); 16.8% (V) and 13.9% (VI) with a malignant risk of 9% (II); 100% (III); 26.3% (IV); 76.4% (V) and 96.4% (VI). The percentage of TIRADS subgroups were: 6.9% (1); 11.4% (2); 30.2% (3); 34.2% (4) and 17.3% (5) with corresponding malignant risks were: 0% (1); 4.4% (2); 14.8% (3); 47.8% (4)
and 86.8% (5). Bethesda system has sensitivity, specificity, positive diagnostic value, negative diagnostic value of 69.7%; 92.8%; 85.5%; and 83.6% (with the cut off are groups V and VI). TIRADS system whose sensitivity, specificity, positive diagnostic value, negative diagnostic value were 86.8%; 67.5%; 61.6% and 89.4% respectively (cut off were groups of 4 and 5). The area under the curve (AUC) of Bethesda V, VI subgroups was 0.81 (p <0.001) and of TIRADS 4 and 5 subgroups was 0.25 (p <0.001).
Conclusion: The Bethesda system for reporting thyroid cytopathology was more valuable than Thyroid Imaging Reporting and Data System [TI-RADS] in diagnosing thyroid malignant nodules
