The Bethesda system of reporting thyroid cytopathology is a standardised system, improving communication between cytopathologists and clinicians, leading to more consistent management approaches. The aim of the research work was to study the utility of Bethesda system in reporting thyroid cytology with histopathological correlation of all the cases undergoing surgical resection.
Methods: We studied all the thyroid cytology cases received between January 2018 to January 2019, and classified them according to the Bethesda system. Histopathological correlation was done for all the cases which underwent surgical resection with evaluation of cyto-histological discrepancies.
Results: Out of 92 cases studied, 68 (73.9%) were benign lesions, 08 (8.7%) were malignant, 06 (6.5%) were Unsatisfactory/Nondiagnostic, 07 (7.6%) were Follicular neoplasm/Suspicious for neoplasm, 2 (2.2%) were suspicious for malignancy, and 1(1.1%) case was reported as Atypia of undetermined significance.
Out of the 49 cases available for histopathological follow-up, cyto-histological discrepancies were noted in 5 cases (10.2%).
Conclusions: Reviewing the thyroid FNAs (fine needle aspirates) using Bethesda system allowed a more specific cytological diagnosis with better interlaboratory agreement. As evidenced by its high sensitivity and specificity, Bethesda system has proven to be a very effective guide for the clinical management of thyroid nodules.
